Please help and explain how you solved it. Thanks.

Answer:

This is 0.14 to the nearest hundredth

Step-by-step explanation:

Firstly we list the parameters;

Drive to school = 40

Take the bus = 50

Walk = 10

Sophomore = 30

Junior = 35

Senior = 35

Total number of students in sample is 100

Let W be the event that a student walked to school

So P(w) = 10/100 = 0.1

Let S be the event that a student is a senior

P(S) = 35/100 = 0.35

The probability we want to calculate can be said to be;

Probability that a student walked to school given that he is a senior

This can be represented and calculated as follows;

P( w| s) = P( w n s) / P(s)

w n s is the probability that a student walked to school and he is a senior

We need to know the number of seniors who walked to school

From the table, this is 5/100 = 0.05

So the Conditional probability is as follows;

P(W | S ) = 0.05/0.35 = 0.1429

To the nearest hundredth, that is 0.14

Solve by elimination: <br> x+y=5 <br> 3x + y= -11<br><br><br><br> Please explain the steps!!!
Firlakuza [10]

Answer: x = -8, y = 13

Step-by-step explanation:

x+y=5

3x+y=-11

now subtract the two equations

x-3x+y-y=5-(-11)

-2x=16, x = -8

now substitute

-8 + y = 5, y = 13
