Answer:

I think it's Answer choice C.)

Not 100% sure but I think I'm correct.

Step-by-step explanation:

There are 3 fives out of 12 sections, so that will be. 3/12

And you spin 150 times, so (3/12 x 150 = 37.5)

Then you round to the nearest tens, so that would give you 40.

So the reasonable estimate of landing on 5 is C.) 40

Answer:

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:

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.

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

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.

Triangle CAT is transformed to produce triangle DOG.

PilotLPTM [1.2K]

Using transformations and congruency concepts, it is found that with these following transformations, the triangles will be congruent.

A reflection, then a translation.
A rotation, then a reflection.

--------------------------

Two triangles are congruent if they have the same lengths of the sides and the same angles.

In a reflection, there is a rule that changes the coordinates (x,y), but does not change the lengths of the sides of the triangles, thus they will still be congruent.
A reflection is also a special case of rotation, thus, in a rotation, the triangles are also congruent.
A translation is also similar to a reflection, using rules to shift the triangle up, down, left or right according to it's coordinates, not changing the sides or angles, thus congruent.
In a dilation, the lengths of the sides are changed, thus, the triangles will not be congruent.

--------------------------

Thus, from the bullet points above, the correct options are:

A reflection, then a translation.
A rotation, then a reflection.
