Mr. Sanchez built a fence to enclose a rectangular
yard for his horse. If the area of the yard to be
enclosed is 2835 square feet, and the length of
the yard is 45 feet, how much fencing is needed?

Answers

9514 1404 393

Answer:

  216 feet

Step-by-step explanation:

The area is given by the formula ...

  A = LW

Solving for width, we have ...

  W = A/L = 2835 ft²/(45 ft) = 63 ft

__

The perimeter is given by the formula ...

  P = 2(L +W)

  P = 2(45 ft +63 ft) = 2(108 ft)

  P = 216 ft

216 feet of fencing are needed to enclose the area.

What are squares of a number?

Square numbers are numbers that can be multiplied by themselves.

Given that, The sum of the squares of two positive numbers is 73 and the difference of the squares of the numbers is 55.

Let the numbers be x and y, then,

x²+y² = 73

x²-y² = 55

On solving, we get,

x² = 9

x = 3

Putting x = 3 in first equation, we get

3²+y² = 73

y² = 64

y = 8

Hence, the required numbers are 3 and 8.

An administrator at a local high school wants to investigate whether there is an association between the grade level of a student (either ninth, tenth, eleventh, or twelfth) and how the student commutes to school (either walks, bikes, takes the bus, receives a ride, or drives). After a chi-square test for association was conducted, the results indicated that the chi-square test statistic was 14.63 with a p-value of 0.2623. Which of the following is the correct interpretation of the p-value in the context of the test?

a. There is a 26.23 percent chance that grade level and how a student commutes to school are independent.
b. There is a 26.23 percent chance that there is no association between grade level and how a student commutes to school.
c. Assuming there is no association between a student's grade level and how the student commutes to school, there is a 26.23 percent chance of finding a test statistic that is 14.63 or larger.
d. Assuming that a student's grade level and the way the student commutes to school are dependent, there is a 26.23 percent chance of finding a test statistic that is 14.63 or larger.
e. Assuming that a student's grade level and the way the student commutes to school are dependent, there is a 26.23 percent chance of finding a test statistic that is 14.63 or smaller.

Answers

Answer:

c.

Step-by-step explanation:

The following is how the p-value should be interpreted:

The probability of getting the test statistics value at least as intense as it might have been acquired during the test, assuming the null hypothesis is true, is considered as the p-value.

Null hypothesis

[tex]\mathbf{H_o :}[/tex] A student's grade level has no bearing or association on how they commute to school.

Alternative hypothesis;

[tex]\mathbf{H_1: }[/tex] There is a link between a student's grade level and the way they get to school.

The test statistic's value is 14.63, and the p-value is 0.2636.

As a result, the p-value is interpreted as that of option c in the question.

Answer: C

Step-by-step explanation: Because the p value is less than 0.05 you know that your null hypothesis can be rejected and thus your alternative can have significant evidence to be proven. Thus you can eliminate answer choices B, and E. A and B can be rejected because your p value from your chi square test is telling you the likelihood of your chi square falling in a certain category of the graph.

You purchase a new car for $24,000. If you obtain a 5 year bank loan at 2.75% compounded monthly, what is your monthly loan payment?

Answers

Answer:

The monthly loan payment is of $458.88.

Step-by-step explanation:

Compound interest:

The compound interest formula is given by:

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

Where A(t) is the amount of money after t years, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per year and t is the time in years for which the money is invested or borrowed.

Amount owed after 5 years:

Loan of 24000 means that [tex]P = 24000[/tex]

5 years means that [tex]t = 5[/tex]

Interest rate of 2.75% means that [tex]r = 0.0275[/tex]

Compounded monthly means that [tex]n = 12[/tex]

The amount is A(5). So

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

[tex]A(5) = 24000(1 + \frac{0.0275}{12})^{12*5}[/tex]

[tex]A(5) = 27533[/tex]

What is your monthly loan payment?

$27,533 in 5 years = 5*12 = 60 months. So

27533/60 = 458.88

The monthly loan payment is of $458.88.

Jazmin takes a ride share service home from the airport. The ride share service charges $5 as an initial cost to pick her up, and $2.25 for every mile to her final destination. Jazmin's ride home cost a total of $38.75.


Write an equation to represent the situation. Let m represent the number of miles to her home. Do not use any spaces or extra symbols.

Answers

Answer:

[tex]5+2.25m=38.75[/tex]

Step-by-step explanation:

Let [tex]m[/tex] represent the number of miles to Jazmin's home.

Initial cost to pick Jazmin [tex]=\$5[/tex]

Cost per mile [tex]=\$2.25[/tex]

Therefore,

Cost for [tex]m[/tex] miles [tex]=\$2.25m[/tex]

Total cost of Jazmin's ride = Initial cost to pick Jazmin + Cost for [tex]m[/tex] miles

                                            = [tex]5+2.25m[/tex]

Also, total cost incurred [tex]=\$38.75[/tex]

So, equation that represent the above situation is [tex]5+2.25m=38.75[/tex]

Answer:

y = 3x + 41

Step-by-step explanation:

First, lets set up the slope-intercept form equation, that is...

y = mx + b

m = slope

b = y-intercept

because the y-intercept is a positive value, it cannot be y=-3x-41 or y= 3x-41

now, we know that b = 41, but what is the slope?

Well, here are tips for doing slope

if the line is gradually increasing upwards, then it is a positive slope

if the line is gradually decreasing downwards, then it is a negative slope

because the line in the picture is positive, this proves y=-3x+41 wrong, therefore making y = 3x + 41 the only correct answer

Therefore, your correct answer is y = 3x + 41

Is urgent If a line passes through the points (2, 7) and (7,9), its slope is

Find the compound amount and compound interest on $6000 invested at 6%
compounded continously for 6 years. Use e = 2.71828
(Round value of exponential expression upto 4 decimal places.)

Answers

Answer:

$8,511.1147

Step-by-step explanation:

Compound interest formula is expressed as;

A = P(1+r)^n

P is the amount invested = $6000

r is the rate = 6% = 0.06

t is the time = 6yrs

A is the compound amount

A = 6000(1+0.06)^6

A = 6000(1.06)^6

A  = 6000(1.4185)

A = 8,511.1147

Hence the compound amount to 4dp is $8,511.1147
