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
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>
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>
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
Total = Price of boots + Tax amount
Tax: $2
Total: $27

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
