I don't understand this question like for example what do you do with the $28.00 if it's not in the graph?​

Answer:

2000 because you got to subtract

Answer:

Generally, the algebraic expression should be any one of the forms such as addition, subtraction, multiplication and division. To find the value of x, bring the variable to the left side and bring all the remaining values to the right side. Simplify the values to find the result.

Answer:

628

Step-by-step explanation:

1) Find the circumference of the wheel (the distance it travels in 1 revolution)

[tex]C=\pi d[/tex] where d is the diameter

Plug in 2 ft as the diameter

[tex]C=(3.14) (2)\\C=6.28[/tex]

Therefore, the circumference of the wheel is 6.28 ft.

2) Multiply the circumference by 100

6.28 × 100

= 628 ft

Therefore, Joe would travel 628 feet if his wheel turns exactly 100 complete revolutions in one direction.

Answer:

Step-by-step explanation:

This question is about the benefits of estimation.

1300/13 is easy and results in 100.

1287/13 can be approximated by 1300/13:  1287/13 ≈ 100.

Actually, 1287 = 1300 - 13 = 13(99); just subtract 1 from 100.  

So:  1287/13 = 1300 - 13 = 1287.  A nice bit of mental math!

Answer:

the probability is 0.0067

Step-by-step explanation:

The computation of the probability of receiving no e-mails during an hour is shown below;

Let us assume x be the number of emails received during an hour

Now the probability of receiving no e-mails is

= e^-5 × 5^0÷ 0!

= e^-5 × 1  ÷ 1

= e^-5

= 0.00674

= 0.0067

Hence, the probability is 0.0067

Answer:

The domain of a function is the set of all possible x values that satisfy the equation. We cannot answer this question without first knowing what the equation for f(x) is.

Step-by-step explanation:

Take for example the function y = f(x) = [tex]x^{2} +3[/tex]. Here, you can plug in literally any value for x and still get our a real number. Thus, the domain of f(x) is (-∞, ∞).

However, if your function is y = f(x) = [tex]\frac{2}{\sqrt{x+3} }[/tex] , not every x value is acceptable. First, we cannot have the denominator (bottom part) of the fraction be zero, because division by zero is undefined. Thus, x = -3 is not an acceptable value for x.

We also cannot take the square root of a negative number. Thus, we have the rule that x + 3 must be greater than or equal to zero.

[tex]x+3 > 0\\\\x > -3\\[/tex]

Normally we would use greater than or equal to zero, but because this is in the denominator, we don't want it to equal zero (and thus x = -3 is not acceptable).

So, the domain of x is (-3, ∞). The parenthesis tell us we do not include the negative three and we do not include infinity. In other words, the domain of x is all numbers greater than -3 but less than infinity.

So, first look at your equation for f(x), then see which values of x don't break the rules of math like division by zero or square roots of negative numbers. Good luck!

Answer:

15.5t=18(t-0.5) is the correct answer

Step-by-step explanation:

if the first boat travels t time then the second traveld t-0.5 time to take over

The expression on each side of each equation represent the distance travelled. Hence, 15.5t=18(t-0.5) is the correct answer

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

We are given that boat left Kyuquot and headed west at 15.5 km/h.

A second boat left Kyuquot half an hour later and headed west at 18 km/h.

Helga’s Equation 15.5t = 18(t + 0.5)

Dora’s Equation 15.5t = 18(t - 0.5)

Therefore, if the first boat travels t time then the second travelled

t-0.5 time to take over

By using the formula for the volume of a cylinder we will see that the approximate radius must be 8.2 inches.

Remember that for a cylinder of radius R and height H the volume is:

[tex]V = 3.14*R^2*H[/tex]

In this case, the height is twice the radius, so we have:

H = 2R

[tex]V = 3.14*R^2*2R = 6.28*R^3[/tex]

And we know that the volume must be 3,500 in^3, now we can replace that and solve for R, we will get:

[tex]3,500 in^3 = 6.28*R^3[/tex]

[tex](3,500 in^3/6.28)^{1/3} = R = 8.2 in[/tex]

The approximate radius of the cylinder must be 8.2 inches.

Answer:

The country's population increased by about 16.73% during this time period.

Step-by-step explanation:

Percent increase:

The percent increase is given by the change multiplied by 100 and divided by the initial value.

In 1990, the population was about 263 million people In 2014, the population was about 307 million people.

Change: 307 - 263 = 44

Initial population: 263

Percentage increase:

44*100/263 = 16.73%

The country's population increased by about 16.73% during this time period.

Answer:

I = $ 1,937.50

Step-by-step explanation:

Equation:

I = Prt

Calculation:

First, converting R percent to r a decimal

r = R/100 = 3.875%/100 = 0.03875 per year,

then, solving our equation

I = 10000 × 0.03875 × 5 = 1937.5

I = $ 1,937.50

The simple interest accumulated

on a principal of $ 10,000.00

at a rate of 3.875% per year

for 5 years is $ 1,937.50.

Answer:

m<UVT = 114°

Step-by-step explanation:

½(sum of intercepted arcs) = measure of vertex of an angle inside a circle

Thus:

½(FS + UT) = m<UVT

Substitute

½(53 + 175) = m<UVT

½(228) = m<UVT

114 = m<UVT

m<UVT = 114°

Answer:

The manager should use a sample size of 12 to determine the average travel expenditure

Step-by-step explanation:

Spent about 20 cents per mile. Distance of 15 miles

We have the mean per a distance, so we use the Poisson distribution. In this distribution, the standard deviation is the square root of the mean. So

[tex]\mu = 20*15 = 300, \sigma = \sqrt{300} = 17.32[/tex]

Confidence interval:

We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:

[tex]\alpha = \frac{1 - 0.95}{2} = 0.025[/tex]

Now, we have to find z in the Ztable as such z has a pvalue of [tex]1 - \alpha[/tex].

That is z with a pvalue of [tex]1 - 0.025 = 0.975[/tex], so Z = 1.96.

Now, find the margin of error M as such

[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]

In which [tex]\sigma[/tex] is the standard deviation of the population and n is the size of the sample.

What sample size should the manger use to determine the average travel expenditure?

This is n for which M = 10. So

[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]

[tex]10 = 1.96\frac{17.32}{\sqrt{n}}[/tex]

[tex]10\sqrt{n} = 1.96*17.32[/tex]

[tex]\sqrt{n} = \frac{1.96*17.32}{10}[/tex]

[tex](\sqrt{n})^2 = (\frac{1.96*17.32}{10})^2[/tex]

[tex]n = 11.52[/tex]

Rounding up

The manager should use a sample size of 12 to determine the average travel expenditure

Step-by-step explanation:

The prism shown is a rectangular prism with a height of 3 in a length of 5 in and a width of 8 in

The volume of a rectangular prism can easily be calculated by multiplying the height by the length by the width

So V = 3 * 5 * 8

3 * 5 = 15

15 * 8 = 120

V = 120
