Find the final amount of money in an account if $7, 300 is deposited at 2% interest compounded semi annually and the money is left for 7 years

Answers

The final amount of money in the account after 7 years would be $8,790.56.

To calculate the final amount of money in an account, we can use the formula for compound interest:

A = [tex]P(1 + r/n)^{(nt)[/tex]

where A is the final amount of money, P is the initial amount of money, r is the annual interest rate, n is the number of times the interest is compounded per year, and t is the number of years.

In this case, we have P = $7,300, r = 0.02 (since the interest rate is 2%), n = 2 (since the interest is compounded semi-annually), and t = 7 (since the money is left for 7 years). Plugging these values into the formula, we get:

A = $7,300(1 + 0.02/2)¹⁴

A = $7,300(1.01)¹⁴

A = $8,790.56

This means that the initial investment of $7,300 earned $1,490.56 in interest over the 7-year period due to the compounding effect of the semi-annual interest payments.

Question 5
Which of the following functions best describes this graph?
4
Ay=x²-2x+4
OB. y +9x+18
OC. ys (x+5)(x-4)

Answers

Answer:

D. y = (x - 3)(x - 6)

Step-by-step explanation:

The graph shows a parabola and the parabola intersects the x-axis at (-6, 0) and at (-3, 0).  When a function intersects the x-axis, the y value must automatically equal 0, since there is only horizontal movement on the x-axis.

(x-3)(x-6) is a binomial expression that will make a quadratic equation when expanded.  We refer to the coordinate where a parabola intersects the x-axis as roots, which are numbers that make the quadratic equation equal 0.

We know from the zero-product property, that when the product of two numbers is 0, at least on the numbers must be 0 (e.g., 4 * 0 = 0 or even 0 * 0 = 0).  Thus, we can solve any quadratic equation in the the x-intercept form (i.e., the form tha (x-3)(x-6) is currently in) by setting both expressions equal to 0 and solving for x.  This wil give an x-coordinate both times, but since you set the equations equal to 0, you know that your y-coordinate each time is 0:

Solution for x - 3 = 0:

x - 3 = 0

x = 3

Solving for x - 6 = 0

x - 6 = 0

x = 6

You can check by plugging in 3 for x and 6 for x and see if you get 0:

3 for x:

(3 - 3)(3 - 6) = 0

0 * -3 = 0

0 = 0

6 for x:

(6 - 3)(6 - 6) = 0

3 * 0 = 0

0 = 0

A planter box has dimensions 30 in × 15 in × 18 in (Length × Width × Height).
a. Find the volume of the box in cubic feet and in cubic yards.
b. Potting soil is sold in 1.5 cubic-foot bags, and each bag weighs 11.2 pounds. How many
pounds of soil does the box hold?
c. You’d like to paint the sides (but not the bottom) of the planter box. You plan on
applying one coat of paint. How many square feet of paint will you need?
88

Answers

Okay, let's solve this step-by-step:

a)

Length = 30 in = 2.5 ft

Width = 15 in = 1.25 ft

Height = 18 in = 1.5 ft

Volume (cubic ft) = Length x Width x Height

= 2.5 x 1.25 x 1.5 = 3.75 cubic ft

Volume (cubic yards) = 3.75 / 27 = 0.14 cubic yards

b)

Since the box volume is 3.75 cubic ft and potting soil bags are 1.5 cubic ft,

you will need 3.75 / 1.5 = 2.5 bags of soil.

Each bag weighs 11.2 lbs, so 2.5 bags will weigh 2.5 * 11.2 = 28 lbs of soil.

c)

To paint the sides of the box, you need:

Length (2 sides) = 30 in x 2 = 60 in

Width (2 sides) = 15 in x 2 = 30 in

Height (4 sides) = 18 in x 4 = 72 in

Total inches of sides = 60 + 30 + 72 = 162 in

Conversion: 162 in / 12 in = 13.5 square ft

So you will need about 14 square feet of paint.

A. Domain: x≥−4, Range: y≥0
B. Domain: x≥4, Range: y≥0
C. Domain: x≤4, Range: y≤0
D. Domain: x≥0, Range: y≥4

Answers

Using the function y = √ (x-4) has the following:

Domain: x≥−4, Range: y≥0.

Correct answer is A.

Define a function?

A function is a relationship between each element of a non-empty set A and at least one element of another non-empty set B. A relation f between a set A (the function's domain) and a set B is how a function is defined in mathematics (its co-domain). Anytime an A and b B exist, f = (a,b)|

The domain of the function y=√ (x-4) is restricted by the square root of a non-negative number, which means that x-4 must be greater than or equal to zero. Thus, we have:

x-4 ≥ 0

x ≥ 4

Therefore, the domain of the function is x≥4.

The range of the function is determined by the output values of the function. Since the square root of any non-negative number is always non-negative, the output values of the function y=√x-4 will always be non-negative. Thus, the range of the function is y≥0.

Therefore, the correct answer is A. Domain: x≥−4, Range: y≥0.

Hence, the critical value for the 81% confidence interval is 1.311 occurs while comparing equations (1) and (2).

Explain about the Critical Values:

The cut-off scores used during confidence intervals, hypothesis testing, and other statistical techniques are known as the crucial values. They are used to establish the boundaries of confidence intervals in the case of confidence intervals.

Level of confidence c = 0.81

The degree of assurance c =  81%.

Now, the overall confidence level is shown as (1−α) , where α is the significance level.

adam bought a skateboard that is on sale for 35% off the original cost is 150 what is the sale price

Answers

Answer:

$97.50

Step-by-step explanation:

To calculate the sale price of the skateboard, we need to apply a discount of 35% to the original cost of $150:

Discount amount = 35% x $150 = $52.50

The sale price is the original cost minus the discount amount:

Sale price = $150 - $52.50 = $97.50

Therefore, the sale price of the skateboard after a 35% discount is $97.5

The sale price of the skateboard is $97.50.

To calculate the sale price, we need to first determine the amount of the discount, and then subtract that discount from the original price.

The discount is 35% of the original price:

Discount = 0.35 x 150 = 52.50

So the sale price is the original price minus the discount:

Sale price = 150 - 52.50 = 97.50

t=
reject or do not reject the null hypothesis
is there enough evidence to support the claim

Answers

As per the hypothesis, t (1.7518) is less than the critical value (1.7823), we fail to reject the null hypothesis.

For this scenario, our null and alternative hypotheses can be stated as follows:

H0: u₁ - u₂ = 0 (There is no significant difference between the mean earnings of PGA and LPGA golfers)

H1: u₁ - u₂ > 0 (There is a significant difference between the mean earnings of PGA and LPGA golfers)

Assuming a level of significance (alpha) of 0.05, the degrees of freedom can be calculated as follows:

df = (s₁²/n₁ + s₂²/n₂)² / [(s₁²/n₁)²/(n₁-1) + (s₂²/n₂)²/(n₂-1)]

where s₁ and s₂ are the sample standard deviations, n₁ and n₂ are the sample sizes.

For the PGA sample, we have n₁ = 8, s₁ = 3139.71

For the LPGA sample, we have n₂ = 8, s₂ = 1232.59

Using the above formula, we get df = 12.61

Using a t-distribution table with 12 degrees of freedom and a one-tailed test, we find the critical value to be 1.7823.

Next, we need to calculate the test statistic t, which can be calculated as follows:

t = (x₁ - x₂) / √[s₁²/n₁ + s₂²/n₂]

where x₁ and x₂ are the sample means.

For the PGA sample, we have x₁ = 4358.22

For the LPGA sample, we have x₂ = 1128.50

Using the above formula, we get t = 1.7518.

Now, we can compare the test statistic t to the critical value 1.7823. Since In other words, we do not have enough evidence to support the claim that there is a significant difference between the mean earnings of PGA and LPGA golfers.

Margarita borrows $14,000 from her uncle and agrees to repay it in monthly installments of $400. Her uncle charges 0.9% interest per month on the balance.

(a) If her balance An in the nth month is given recursively by A0 = 14,000 and An = k · An − 1 − 400, what is k?

(b) Find her balance after two months. (Round your answer to the nearest cent.)

Answers

Answer:

Step-by-step explanation:

(a) We know that the balance An in the nth month is given by:

An = k · An-1 - 400

where A0 = 14,000. Substituting n = 1, we get:

A1 = k · A0 - 400

A1 = k · 14,000 - 400

We also know that her uncle charges 0.9% interest per month on the balance. This means that the balance after one month should be:

A1' = A0 + 0.009 · A0 - 400

A1' = 14,000 + 0.009 · 14,000 - 400

A1' = 14,126

Setting A1 = A1', we can solve for k:

k · 14,000 - 400 = 14,126

k = 1.009

Therefore, k is approximately 1.009.

(b) To find her balance after two months, we can use the recursive formula with n = 2:

A2 = k · A1 - 400

A2 = 1.009 · 14,126 - 400

Using a calculator, we get:

A2 ≈ 14,272.34

Therefore, her balance after two months is approximately $14,272.34.

Which car should Andre buy? How many more miles per gallon can he
drive in this car than the other car?

Answers

Answer: Andre should buy Car 2. Brainliest?

Step-by-step explanation:

To compare the gas mileage of the two cars, we need to find out how many miles each car can travel per gallon of gas.

For Car 1: y = 25x

This means that for every gallon of gas used (x), the car can travel 25 times that amount in miles (y). So, the gas mileage for Car 1 is 25 miles per gallon (mpg).

For Car 2: we can calculate the miles per gallon by dividing the total miles traveled by the number of gallons of gas used:

For 2 gallons of gas, the car can travel 60 miles. So, the gas mileage is 30 mpg (60 miles ÷ 2 gallons).

For 5 gallons of gas, the car can travel 150 miles. So, the gas mileage is 30 mpg (150 miles ÷ 5 gallons).

For 7 gallons of gas, the car can travel 210 miles. So, the gas mileage is 30 mpg (210 miles ÷ 7 gallons).

For 8 gallons of gas, the car can travel 240 miles. So, the gas mileage is 30 mpg (240 miles ÷ 8 gallons).

For 11 gallons of gas, the car can travel 330 miles. So, the gas mileage is 30 mpg (330 miles ÷ 11 gallons).

Therefore, Car 2 has a consistent gas mileage of 30 mpg.

From the above calculations, we can see that Car 2 has a better gas mileage compared to Car 1. Car 2 can travel 30 miles on a gallon of gas, while Car 1 can only travel 25 miles on a gallon of gas.

Therefore, Andre should buy Car 2 if he wants to get the best gas mileage. Car 2 can travel 5 more miles per gallon than Car 1.

a. A bag contains 4 red marbles, 5 yellows marbles, and 7 whites marbles. If a marble is drawn from the bag, replaced, and another marble is drawn,
what is the probability of drawing first a marble and then a marble?

Answers

Answer: 5/64

Step-by-step explanation:

The probability of drawing a red marble on the first draw is 4/16 = 1/4 (since there are 4 red marbles out of 16 total marbles).

After replacing the first marble, the probability of drawing a yellow marble on the second draw is 5/16 (since there are 5 yellow marbles remaining out of 16 total marbles).

Therefore, the probability of drawing a red marble and then a yellow marble is (1/4) x (5/16) = 5/64

R Calculation

r = ∑((X - My)(Y - Mx)) / √((SSx)(SSy))

r = 15978328.125 / √((119242794.375)(2396869.375)) = 0.9451

Thus, the value of R is 0.9451.

4. This is a strong positive correlation, which means that high X variable scores go with high Y variable scores (and vice versa).

5) The value of R², the coefficient of determination, is 0.8932.

To drive this, just square the coefficient of determination. That is

R² = 0.9451² = 0.8932

5. To compute the standard errors of the estimate:


SE = √(SSE / (n-2))

where SSE is the sum of squared errors and n is the sample size.

From the regression output, we have SSE = 0.9326 and n = 40.

SE = √ (0.9326 / (40-2)) = 0.1570

Therefore, the standard error of estimate is 0.1570.



6) Yes, because the coefficient of determination is high (0.8932), indicating that 89.32 % of the variability i  n the amount spent can be explained by the linear relationship with monthly  income.

An integer A written in an n-based number system is 647, while written in an (n+2)-based number system is 513. Write the number A in the 10 number system! (n is of course a positive integer)​

Answers

Answer:

79

Step-by-step explanation:

Let's start by writing out what we know:

A = 647 in base-n

A = 513 in base-(n+2)

To find A in base-10, we need to use the place value system and the definition of each base. Let's first convert A to base-10 using the given information.

In base-n, A is equal to:

A = 6n^2 + 4n + 7

In base-(n+2), A is equal to:

A = 5(n+2)^2 + 1(n+2) + 3

A = 5(n^2 + 4n + 4) + (n + 2) + 3

A = 5n^2 + 21n + 20

Now we have two expressions for A, so we can set them equal to each other and solve for n:

6n^2 + 4n + 7 = 5n^2 + 21n + 20

Simplifying and rearranging, we get:

n^2 + 8n + 13 = 0

Using the quadratic formula, we can solve for n:

n = (-8 ± sqrt(8^2 - 4(1)(13))) / (2(1))

n = (-8 ± 2) / 2

n = -3 or n = -5

Since n is a positive integer, we can disregard the negative solution and conclude that n = 3.

Now that we know n, we can substitute it back into the expression for A in base-n and solve for A in base-10:

A = 6n^2 + 4n + 7

A = 6(3^2) + 4(3) + 7

A = 79

Therefore, the number A written in base-10 is 79.

A wildlife group is trying to determine how many wild hogs are in a certain area. They trapped, tagged, and released 20 wild hogs. Later, they counted 8 wild hogs out of the 40 they saw.
What can the wildlife group estimate is the total population of wild hogs in that area

A. 80
B. 90
C. 100
D. 16

Answers

Answer:

The correct answer is 16

Step-by-step explanation:

Answer:

C. 100

Step-by-step explanation:

Assuming that the proportion of tagged hogs in the population is the same as the proportion of tagged hogs in the sample that was later observed, we can set up a proportion to estimate the total population of wild hogs:

tagged hogs in population / total population = tagged hogs in sample / size of sample

We know that 20 wild hogs were tagged and released, and that 8 out of 40 hogs observed were tagged. So we can plug these numbers into the proportion and solve for the total population:

20 / total population = 8 / 40

Simplifying this equation, we get:

total population = (20 * 40) / 8 = 100

Therefore, the wildlife group can estimate that the total population of wild hogs in the area is 100. Answer choice C is correct.

Hope this helps!

You work independently as a copier salesperson. Last month, you sold 26 printers at a cost of $1,750 each. The cost of goods sold for each printer is $975. Additional operating expenses include your salary ($3,000/month), advertising ($50/month), and office lease ($550/month). Use this information to calculate (a) your gross profit and (b) your net income.

Answers

(A) The gross profit is $20,150.

(B) The net income is $16,550

To solve this problem

(A) To calculate the gross profit, we need to subtract the cost of goods sold from the total revenue generated by selling the printers.

Total revenue = 26 x $1,750 = $45,500

Cost of goods sold = 26 x $975 = $25,350

Gross profit = Total revenue - Cost of goods sold

Gross profit = $45,500 - $25,350

Gross profit = $20,150

Therefore, the gross profit is $20,150.

(B) To calculate the net income, we need to subtract all the operating expenses from the gross profit.

Gross profit = $20,150

Salary = $3,000

Advertising = $50

Office lease = $550

Total operating expenses = $3,600

Net income = Gross profit - Total operating expenses

Net income = $20,150 - $3,600

Net income = $16,550

Therefore, the net income is $16,550.

The standard deviation for non-employed students is given as 0.524,

the margin of error is 0.083 and the 90% confidence interval for the mean GPAs of non-employed students is (3.147, 3.313).

Variables needed to solve the problem Sample size (n)

Sample mean, Sample standard deviation (s), Confidence level (CL)

Margin of error (E)

b. The standard deviation for non-employed students is given as 0.524.

c. Point estimate:

The point estimate for the mean GPA of non-employed students is the sample mean, which is given as 3.23.

Margin of error:

We can use the formula for the margin of error:

E = z(s/√n)

For a 90% confidence level, the critical value is 1.645.

E = 1.645(0.524/√114) = 0.083

Therefore, the margin of error is approximately 0.083.

d. Confidence interval:

The confidence interval is given by the formula:

(3.23 - 0.083, 3.23 + 0.083)

= (3.147, 3.313)

Therefore, the 90% confidence interval for the mean GPAs of non-employed students is (3.147, 3.313).
