A pharmaceutical company wants to test the effectiveness of a new allergy drug. The company identifies 250 females ages 30 to 35 who suffer from severe allergies. The subjects are randomly assigned into two
groups. One group is given the drug and the other is given a placebo that looks exactly like the drug. After
six months, the subjects' symptoms are studied and compared.
Which of the following best describes the experimental units in this experiment?

The time it took to implement the study

The severe allergies

The new allergy drug

The 250 females ages 30 to 35

yes yes yes yes yes yes yes yes yes

damm bro the struggle

step-by-step explanation:

the 1st digit is in the 100s n its 1

step-by-step explanation:

3,589÷18 = 199.389

so the first digit of the quotient is in the 100s n its 1

let's cover over the formula of the vertex:

y = a(x – h)^2 + k

in this formula, (h,k) are the vertex, always remember that the positive or negative value of the vertex is based on the sign it has.

for example, if the vertex is -3,-6 then both the x and y value would have the positive sign attached to it and if it were a positive x and y value, then a negative sign would be attached to it.

with that being said, for our problem the x value is a positive one so we are looking for a number with a negative sign next to it, in this case the first and second choice.

however, for the first answer choice it isn't quite part of the formula so we know that the answer choice correctly displays the x value.

to confirm, we can see if the -1 fits correctly with the second answer choice, and as mentioned above a negative number will have a positive sign attached to it. so, for our problem we can see that -1 has been changed to +1, so we can confirm that the second answer choice is correct.

hence, our final answer is y=(x - 1)^2 + 1
