Mrs. Daly's reading classes were surveyed about their reading preferences. The data is summarized in the table below.
andriy [413]

Answer:

Required probability is 0.19

Step-by-step explanation:

The two-way table for the given data is,

                              Fiction                Non-Fiction                Total

9th grade                35                            8                             43

10th grade               52                            12                           64

Total                        87                            20                           107

It is required to find the probability of the students who prefer to read non-fiction novels, given that they are in 9th grade.

That is, to find the conditional probability P(Non-fiction| 9th\ grade).

Now, P(A|B)=\dfrac{P(A\bigcap B)}{P(B)}

So, we get,

P(Non-fiction| 9th\ grade)=\dfrac{(Non-fiction\bigcap 9th\ grade)}{P(9th\ grade)}\\\\P(Non-fiction| 9th\ grade)=\dfrac{8}{43}\\\\P(Non-fiction| 9th\ grade)=0.19

<h3>Thus, the required probability is 0.19.</h3>

— 7x — бу = — 15 Determine the intercepts of the line.
____ [38]

Answer:

see below

Step-by-step explanation:

— 7x — бу = — 15

To find the x intercept set y = 0 and solve for x

-7x - 0 = -15

-7x= -15

Divide by -7

-7x/-7 = -15/-7

x = 15/7

The x intercept is (15/7,0)

To find the y intercept set x = 0 and solve for y

o— бу = — 15

— бу= -15

Divide by -6

— бу/-6= -15/-6

у= 5/2

The y intercept is (0,5/2)
