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

What is the surface are of a rectangular prism of the length is 18cm the width 6cm and the height 3cm
Harlamova29_29 [7]

The surface area of rectangular prism is 360 square inches

<em><u>Solution:</u></em>

Given that rectangular prism of the length is 18 cm the width 6 cm and the height 3 cm

To find: Surface area of rectangular prism

<em><u>The Surface area of rectangular prism is given by formula:</u></em>

A=2(wl+hl+hw)

Where,

"l" is the length and "h" is the height and "w" is the width of prism

From given,

l = 18 cm

w = 6 cm

h = 3 cm

<em><u>Substituting the values in formula,</u></em>

A = 2((6 \times 18) + (3 \times 18) + (3 \times 6))\\\\A = 2(108+54+18)\\\\A = 2 \times 180\\\\A = 360

Thus surface area of rectangular prism is 360 square inches

Tax: $2

Total: $27

Step-by-step explanation:

Given,

Price of boots = $25

Tax = 8%

Amount of tax = 8% of price of boots

Amount\ of\ tax = \frac{8}{100}*25\\Amount\ of tax=\frac{200}{100}\\Amount\ of\ tax=\$2

Total = Price of boots + Tax amount

Total = 25+2=\$27

Tax: $2

Total: $27

Help again pleaseeeeeee
lisabon 2012 [21]
Ok so we have the parabola at origin of y=-12 and crosses x-axis at points x=1,8 so, we could just look at where it crosses the x-axis and find it directly from there. it crosses x-axis at 1 and 8 so the answer can only be A to fit this criteria
