This is a false statement.

When you are solving using square roots, you need to be aware that answers can be both positive and negative. When we solve this, you see there are two possible answers.

x^2 - 9 = 0

x^2 = 9

x = +/- 3

While 3 is an answer, so is -3. If we square either of those numbers, we get 9, which will satisfy the equation.

Quan is inviting 3 friends to a party. Each friend wants 8 cookies and each box has 6 cookies.How many boxes should Quan get?
Anastasy [175]
First, figure out how many total cookies you need. You do this by multiplying the number of friends times the number of cookies each friend will get.

8 x 3 = 24

Then, you take the number of cookies and divide it by the number in each box to find the number of boxes you need.

24/6 = 4

Quan should get 4 boxes.

skelet666 [1.2K]

0.67n + 320

=(0.67 * 430) + 320

= 288.1 + 320

= $608.1

0.67n + 320 = 728.70

0.67n = 728.70 - 320

0.67n = 408.7

n = 408.7 / 0.67

n = 610 Bags of peanuts

Solve this system of equations by using the elimination method -2x-2y=-6, 3x+4y=8
adoni [48]

Step-by-step explanation:

- 2x-2y=-6

3x+4y=8

multiply equation (1) by 3 and equation (2) by 2

- 6x-6y=18

6x+8y=16

Add

2y=34

y= 34÷2

y=17

substitute 17 for y in equation (2)

3x+4y=8

3x+4(17)=8

3x+68=8

3x=8-68

3x=-60

x=-60÷3

x=-20

x=-20,y=17

Using an applet, we found that the theory-based test results in a t-statistic of -7.25 and p-value less than 0.0001. State your
11111nata11111 [884]

Answer:

b. We have very strong evidence that the long-run average guess of the population size of Milwaukee, Wisconsin is smaller with the anchor of Green Bay than with the anchor of Chicago.

Step-by-step explanation:

Smaller p-value indicates a strong evidence in favor of the alternative hypothesis which means we can reject the null hypothesis. In the given scenario the p-value is 0.0001 which is very small. There is sufficient evidence for the rejection of null hypothesis.
