In kendra’s class, 40 percent of the students earned an a on the math test. twenty students earned an a. kendra needs to find out how many students are in her class. kendra’s work is shown below. 40 / 2 = 20 100 x 2 = 200 what mistake did kendra make? (the / is meant as a division symbol) a. kendra should have multiplied by 4 in both the numerator and the denominator. b. kendra should have divided by 2 instead of multiplying by 2 in the denominator. c. kendra should have added 40 and 20. d. kendra should have the part to whole equation written as 100/40 (100 over 40)

B. Kendra should have divided by 2 instead of multiplying by 2 in the denominator.

Step-by-step explanation:

In Kendra’s class, 40 percent of the students earned an A on the math test.

Let the total students in the class be = x

So, as per the situation given, we can say that

x = 50

Hence, there are 50 students in the class.

We can cross check this as:

So, Kendra surely did a mistake.

Kendra should have divided 100 by 2. But she multiplied by 2.

a, b, c, d are correct.

step-by-step explanation:

we have g(x) = 3 and are required to find which option is a translation of g(x).

now, 'translation' is a transformation which means to shift the function in any direction and the general form of translation is g(x) + k, where k is any real number.

so, according to the options we see that all are correct as they satisfy the general form of translation.

also, it can be seen from the graph below that the function g(x) = 3 is shifted from its position in all the four options.
