PLS HELP ME Advertisements claim that taking an SAT preparation course can significantly
improve performance on the SAT. Assume there are three SAT preparation
services available for students to enroll in, and assume you have 200 students
available to use in your experiment. Explain the design of an experiment to
examine the claim that SAT preparation courses improve SAT scores and, if so,
which of the preparation services would seem to be the best. (15 points)

huh im kind of confused can u explain it in dummy terms

Step-by-step explanation:

the cat is blue because the probability of extension towards the prefix of the diameter of the circle could only mathematically equal to the sum of the roots of the carrots from   your garden.

step-by-step explanation:

the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

the root or roots of a polynomial are the values of the variable that makes the polynomial equal to 0. we can find the roots of a polynomial making the expression equal to 0 and then, isolating the variable (it it has just one variable).

for example, given the following polynomial:

the root or zero of the polynomial, can be found by making the expression equal to 0, and then, isolating the variable, so, finding the root we have:

therefore, we have that the root of the polynomial is equal to 2.

we must remember that the number of roots that a polynomial can have, will depend on the degree of the polynomial, a first degree polynomial have will have one single root, a second degree polynomial (quadratic expression) may have two roots and so.

hence the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

have a nice day!
