In a survey at a local university, 38% of students say that they get less than the recommended eight hours of sleep per night. In a group of 4200 students, how many would you expect get eight or more hours of sleep per night? TIMED TEST

You would expect 2,604 to get 8 or more hours of sleep per night.

Step-by-step explanation:

4,200 x .38 = 1,596 (do not get enough sleep)

4,200 - 1,596 = 2,604

answer:

(-8,7)

explanation:

we know that  

f

(

−

3

)

=

7

therefore, if we wish to get the output as 7, in the function, we need to have our input to be -3.

looking at the function  

f

(

x

+

5

)

, what should the value of x be, such that the input in the function becomes 7?

we simply equate the terms,

x

+

5

=

−

3

x

=

−

8

thus, the point on the new function would be  

(

−

8

,

7

)
