Answer:

#4.  m=0;

#3.  m = \frac{-1}{2}

Step-by-step explanation:

It seems right.

#4.  

Maybe your teacher wants you to write m=0; because when a fraction has a numerator equal to zero then the fraction is zero.

#3.

Maybe your teachers want you to simplify the fraction and write m = \frac{-1}{2}

Answer:

3. The slope is 1/-2

4. The slope is 0/6 or 0

Step-by-step explanation:

Don't worry you did number 3 correctly, but you should always completely simplify your fraction if its possible. In the fraction 4/-8, the numerator and denominator are both divisible by 4 and can be simplified to 1/-2.

You used the equation for finding the slope correctly in number 4, but 8-2=6. You accidently put 7. So, the correct fraction would be 0/6. This can also be simplified because 0 divided by 6 is 0. So, the slope is 0.

A manufacturer is running an experiment using the standard (control) infant formula, and two new formulas, A and B. The goal is
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.

Consider the line y=9x-8
jasenka [17]

Answer:

y=9x+75

Step-by-step explanation:

since we know that the slope must be the same for two lines to be proportional, we are gonna start there.

so our equation is: y= 9x + b

we need to find b to complete our equation, so substitute in the points we were given.

3 = 9(-8) + b

so now,

3 = -72 + b

now we have to isolate b to find out what it is,

3  =  -72 + b

+72   +72

so now: 75= b

Put that back into the starting equation: y = 9x + 75
