First let the line pass -5 since it is the y-intercept.

Next, start from point (0,-5) and rise up by 3 then turn to the right by 2.

That is what the slope represents.

The graph should look like this (see the picture; refresh the page if you can't see it)

The surface area of a sphere is 275.56 1 cm? What is the approximate volume of the sphere?

skad [1K]

Answer:

$V=430.19\ cm^3$ or $V=136.93\pi\ cm^3$

Step-by-step explanation:

The surface area of a sphere is:

$A_s=4\pi r^2$

Where r is the radius of the sphere

In this case we know that $A_s = 275.561\ cm^2$

$4\pi r^2=275.561$

We solve the equation for r

$4\pi r^2=275.561\\r^2 = \frac{275.561}{4\pi}\\\\r=\sqrt{ \frac{275.561}{4\pi}}\\\\r=4.683\ cm$

Now we know the radius of the sphere.

The volume of a sphere is:

$V=\frac{4}{3}\pi r^3$

We substitute the value of the radius in the formula

$V=\frac{4}{3}\pi (4.683)^3$

$V=430.19\ cm^3$

The International Air Transport Association surveys business travelers to develop quality ratings for transatlantic gateway airp

yKpoI14uk [10]

Answer:

Confidence Interval in 95% confidence level for the quality rating is (6.06,7.46)

Step-by-step explanation:

Confidence Interval can be calculated using the formula M±ME where

M is the mean of the sample
ME is the margin of error in a given confidence level

Using the sample obtained from 50 business travelers we get

Mean of the sample is 6.76
standard deviation of the sample is 2.526

Margin of error (ME) around the mean using the formula

ME= $\frac{z*s}{\sqrt{N} }$ where

z is the corresponding statistic in 95% confidence level (1.96)

s is the standard deviation of the sample (2.526)

N is the sample size (50)

Using the numbers in the formula we get:

ME= $\frac{1.96*2.526}{\sqrt{50} }$ ≈ 0.70

Then the confidence interval becomes 6.76±0.70

Identify the quadrant where each point is located. (-5,2) (5,-5) (2,-5) (-4,-5)

Tanzania [10]

(-5,2) is located in the II quadrant because the x is negative and the y is positive.

(5,-5) is located in the IV quadrant because the x is positive and the y is negative.

(2,-5) is also located in the IV quadrant because the x is positive and the y is negative.

(-4,-5) is located in the III quadrant because both x and y are negative.
