Answer:

(0,1) , (2,4) , (4,7)

Explanation:

convert the equation into slope-intercept form (this would be y=3/2x+1)

now plug in random numbers for x and solve for y by multiplying them by 3/2 and adding 1.

You have used the significant level of 0.01 to estimate the average hours of television viewing for the NJ students. What is the

Lorico [155]

Answer:

Step-by-step explanation:

Given : You have used the significant level of 0.01 to estimate the average hours of television viewing for the NJ students.

To Find :What is the chance that our interval estimate does not contain the true population mean?

Solution:

We are given that You have used the significant level of 0.01 to estimate the average hours of television viewing for the NJ students.

So, α=0.01

Significance level indicates a risk of concluding that a difference exists when there is no actual difference.

So, The chance that our interval estimate does not contain the true population mean is 0.01

So, The chance that our interval estimate does not contain the true population mean is $0.01 \times 100 = 1\%$

Hence Option D is true

Betsy is saying for a bird cage. She saves $1 the first week, $3 the second week, $9 the third week, and so on. All together how

Zigmanuir [339]

Answer:

Betsy will save $121 in 5 weeks.

Step-by-step explanation:

We can see that Betsy's savings are 3 times the saving of her last week. We can see that this is an geometric sequence as 1,3,9,..

To find the sum of our geometric sequence we will use $S_{n}=a\cdot \frac{1-r^{n}}{1-r}$ , where n is number of terms we are taking sum of, a is first term of sequence and r is common ratio of the sequence.

$S_{5}=1\cdot \frac{1-3^{5}}{1-3}$

$S_{5}=\frac{1-243}{-2}$

$S_{n}=\frac{-242}{-2}=121$

Therefore, Betsy will save $121 in 5 weeks.

If w represents the width of a rectangle with a length of 12 centimeters and an area of 590 square centimeters, what is the best

Y_Kistochka [10]

The formula for the area of a rectangle is...

Area = length x width

A = L x W

What we know so far...

Area is 590 cm^2

length is 12 cm

width is unknown

Plug all of these into the equation for area of a rectangle:

590 = 12 * w

590 = 12w

Letter A is the correct answer

Hope this helped!
