To find y-intercept bring the formulat to explicit form,

$y=\frac{1}{6}(-48-11x)$

Now put in x = 0 since we are looking at what value y does the function intercept the y-axis.

$y=\frac{1}{6}(-48-11\cdot0)=-8$

The line intercepts y-axis at y = -8.

Hope this helps.

Answer:

y = -11/6x - 8

Step-by-step explanation:

<u>Step 1: Solve for y</u>

11x + 6y = -48

11x + 6y - 11x = -48 - 11x

6y / 6 = (-48 - 11x) / 6

y = -8 - 11/6x

Answer: y = -11/6x - 8

Imagine you are given the diameter of a circle and asked to find its volume. Select the statement that describes what you should

ivanzaharov [21]

Answer:

We need to take the diameter and divide by 2 to find the radius

Step-by-step explanation:

The volume of a sphere is found by

V = 4/3 pi r^3

So we need the radius

We know the diameter

r = d/2

We need to take the diameter and divide by 2

Find the area of the shaded region

PIT_PIT [208]

Answer:

Area of the shaded region= $500inch^2$

Step-by-step explanation:

Area of the shaded region= Area of the triangle- Area of the rectangle

Dimensions of the triangle:

Base= 40 inch

Height= 40 inch

Area of a triangle= $\frac{1}{2}*Base*Height$

$=\frac{1}{2}*40*40\\\\ =\frac{1}{2} *1600\\\\=800 inch^2$

Area of the rectangle= Length*Width

Length=30 inch

Width=10 inch

Area:

$= 30*10\\\\=300 inch^2$

Area of the shaded region= $800-300= 500 inch^2$

A recent study asked U. S. Adults to name 10 historic events that occurred during their lifetime that have had the greatest impa

Nadusha1986 [10]

Using the z-distribution, as we are working with a proportion, it is found that the 99% confidence interval for the proportion of all U. S. Adults who would include the 9/11 attacks on their list of 10 historic events is (0.7458, 0.7942). It means that we are 99% sure that the true proportion for all U.S. adults is between these two bounds.

<h3>What is a confidence interval of proportions?</h3>

A confidence interval of proportions is given by:

$\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}$

In which:

$\pi$ is the sample proportion.

z is the critical value.

n is the sample size.

In this problem, the parameters are:

$z = 2.575, n = 2000, \pi = 0.77$

The lower limit of this interval is:

$\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.77 - 2.575\sqrt{\frac{0.77(0.23)}{2000}} = 0.7458$

The upper limit of this interval is:

$\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.77 + 2.575\sqrt{\frac{0.77(0.23)}{2000}} = 0.7942$

The 99% confidence interval for the proportion of all U. S. Adults who would include the 9/11 attacks on their list of 10 historic events is (0.7458, 0.7942). It means that we are 99% sure that the true proportion for all U.S. adults is between these two bounds.

Answer:

See below

Step-by-step explanation:

AB is a midsegment.

<u>Property of the midsegment is midsegment is half the length of the parallel side of the triangle:</u>

2AB = 88
AB = 44

3x - 4 = 44
3x = 48
x = 16
