Andrew is creating a rectangular dog run in his back yard. The length of the dog run is 18 feet. The perimeter of the dog run mu
ale4655 [162]

Answer: 3\leq x \leq 18

Step-by-step explanation:

Given, the length of the rectangular dog run is 18 feet.

Formula: Perimeter = 2 ( length + width)

Let width be x.

Then, Perimeter = 2 (18 + x ) feet

The perimeter of the dog run must be at least 42 feet and no more than 72 feet.

That is  

42\leq 2 (x+18)\leq 72

Divide inequality by 2, we get

21\leq 18+x\leq 36

Subtract 18 from each side, we get

3\leq x \leq 18

Required inequality : 3\leq x \leq 18

Verizon [17]

Answer:

A. 8

Step-by-step explanation:

The angle shown is a 90 degree right angle (shown by the box where the vertex is)

We see that the first angle inside the right angle is 50 degrees, so the other angle must be 40 because the degrees must add up. We can set up an equation here.

5x=40

After dividing both sides by 5, we get x = 8

bulgar [2K]

Answer:

A.

H0: the mean IGA score is the same for all three formulas.


Ha: the mean IGA score is not the same for all three formulas.

The Group of answer choices are as below:

A.

H0: the mean IGA score is the same for all three formulas.


Ha: the mean IGA score is not the same for all three formulas.

B.

H0: the mean IGA score is the same for all three formulas.


Ha: the mean IGA score is higher for at least one of the two treatment groups than the control group

C.

H0: the mean IGA score is the same for all three formulas.


Ha: the mean IGA score is higher for both treatment groups A and B than the control group.

D. No answer text provided.

Explanation:

Given that a manufacturer is running an experiment using the standard (control) infant formula, and two new formulas, A and B to boost the immune system in infants.

The variable that is measured is Total IGA (in mg per dl) score.

We have to state the hypotheses for one-way ANOVA F test to test if the mean IGA score is the same for all three formulas.

In null hypothesis H0, the mean of all groups are equal and in alternative hypothesis, Ha, the mean of the groups are not the same.

Therefore, the hypothesis tested by the one-way ANOVA F test are:

H0: the mean IGA score is the same for all three formulas.

Ha: the mean IGA score is not the same for all three formulas.

Find m2 ROL if<br><br> m2 ROC = 31° and<br><br> m2 COL = 52°<br><br> 0<br><br> L
Tamiku [17]

Answer:

<h3>83°</h3>

Step-by-step explanation:

Given the parameters

m2 ROC = 31° and

m2 COL = 52°

According to the diagram in the attachment;

m2 ROL =  m2 ROC + m2 COL

Substitute the given values into the expression as shown;

m2 ROL= 31°+52°

m2 ROL = 83°
