Answer:

27.5

Step-by-step explanation:

You know that the member ship is 20 dollars. For every movie rented you pay 2.5 dollars, and if you rent out 3 movies you can multiply 3 by the value of each movie

2.50 x 3 =7.5

20 + 7.5 = 27.5

sweet [91]

Answer:

Kindly check explanation

Step-by-step explanation:

________A___ B___ C___ Total

Male____ 9___13___ 6____ 28

Female_ 20__ 19___ 2____ 41

Total___ 29__ 32___ 8____ 69

If one student is chosen at random,

Find the probability that the student got a C:

P(getting C) = (number of C's) / total number

P(getting C) = 8 / 69

Find the probability that the student was female AND got a "C":

P(female and C):

(number of female who got C / total number)

= 2 / 69

Find the probability that the student was male OR got an "B":

P(male OR B) :

(Number of males or B) = (28 + 32) - 13 = 47

= 47 / 90

find the probability that the student got a 'C' GIVEN they are female:______.

P(C given they are female) :

This is the proportion of females who got C

Total Number of females = 41

Females who got C = 2

Hence,

P(C given they are female) = 2 / 41

How find derivative of function: y=arcsin(2x+1)<br> ...?
Setler [38]
( \arcsin{x})'= \frac{1}{ \sqrt{1-x^2} } &#10;\\&#10;\\ (\arcsin{(2x+1)})'= \frac{1}{ \sqrt{1-(2x+1)^2} } (2x+1)'= \frac{2}{ \sqrt{1-(4x^2+4x+1)} } =&#10;\\&#10;\\= \frac{2}{ \sqrt{-4x^2-4x} } =\frac{2}{ \sqrt{4x(-x-1} )} =\frac{2}{ 2\sqrt{x(-x-1} )} =\frac{1}{ \sqrt{x(-x-1} )}

Aleksandr [31]

The question is incomplete. The complete question is :

Members of a research team are considering three studies related to sleep and learning. The first study involves comparing the scores on a post-study test of learning from two groups of randomly chosen adults, with one group getting at least 7 hours of sleep per night for a week and the other group getting at most 6 hours  of sleep per night for a week. A second study involves asking a random sample of students at a large university to report the average number of hours of sleep they get each night and their college grade point average. A third study involves asking a random sample of high school students in a large school district whether they feel they get enough sleep to stay alert throughout the school day.

Which study appears to look for an association between two variables without actively manipulating either one. What are those variables ?

Solution :

The second study in the context is involved in asking for a random sample of the students at an university to provide a report the average hours of sleep that everybody get each night and also the grade point of their college appears for association between these two variables without actively changing either of one.

These variables are the grade point average of the students and the numbers of hours of sleep.

What statement describes how the graph of the given polynomial would change if the term 2x^5 is added?
vaieri [72.5K]

I don't see any answer choices, so I'm just going to attach an image of the equations graphed on Desmos.

Desmos is a free, online graphing calculator that works really well for problems like this. If you want to get a better view of the graphs and to be able to "interact" with them, just go to the desmos website and put in your equation(s). The picture that I've attached might not be very helpful because it doesn't show the full extent of the graph, so you might want to check it out and do it yourself.

Hope this helps!
