Really ! plz ! will give !

after conducting a survey of all her classmates, midge discovers that the amount of money everyone spends buying books each month has a mean of $30. what does the mean say about the amount her classmates spend on books?

a. half of her classmates spend exactly $30 per month buying books.
b. half of her classmates spend more than $30 per month buying books.
c. the majority of her classmates spend $30 per month buying books.
d. if the amount spent on books per month by all her the classmates is leveled, that amount would be $30.

I took the quiz and the answer is D

Step-by-step explanation:

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.
