Robero will randomly choose 1 book to read. What is the probability that he will
choose an adventure book?
Answer:
Step-by-step explanation:
How many books are there?
6+5+4+3 = 18 books total
How many are adventure books?
3
3 out of 18 books are adventure books
Robero has a 3/18 probability of choosing an adventure book.
Your teacher might want that probability in the lowest possible form. That is because it is the easiest to use and to understand.
You can do this by dividing both numbers by the "numerator" which is the first number in the fraction, (the adventure book count).
3/3 = 1
18/3 = 6
So the fraction can be reduced to 1/6.
Robero has a 1/6 chance of choosing an adventure book.
Sara had 88 dollars to spend on 8 books. After buying them she had 16 dollars. How much did each book cost?
Answer
$9
first take $88 and subtract what you have left which is $16,
88-16 = 72
Now take 72 and divide by number of books bought which was 8
72/8 = 9
So each book cost $9

Answer:
a) f(2) = 4
b) g(3) = 3
c) g(1/3) = -1
d) f(3) = 1/2
e) g(-2) = 2
f) f(π) = 3
Step-by-step explanation:
We are given:
f={(2,4),(-4,3),(3,1/2),(π,3)} and g={(3,3),(-2,2),(1/3,-1)}
We need to find the following values of f and g
a) f(2)
f(2) means when x=2, we need to find the value of y.
Looking at the given f={(2,4),(-4,3),(3,1/2),(π,3)} , when x =2 then y=4
So, f(2) = 4
b) g(3)
g(3) means when x=3, we need to find the value of y.
Looking at the given g={(3,3),(-2,2),(1/3,-1)}, when x =3 then y=3
So, g(3) = 3
c) g(1/3)
g(1/3) means when x=1/3, we need to find the value of y.
Looking at the given g={(3,3),(-2,2),(1/3,-1)}, when x =1/3 then y=-1
So, g(3) = -1
d) f(3)
f(3) means when x=3, we need to find the value of y.
Looking at the given f={(2,4),(-4,3),(3,1/2),(π,3)} , when x =3 then y=1/2
So, f(3) = 1/2
e) g(-2)
g(-2) means when x=-2, we need to find the value of y.
Looking at the given g={(3,3),(-2,2),(1/3,-1)}, when x =-2 then y=2
So, g(-2) = 2
f) f(π)
f(π) means when x=π, we need to find the value of y.
Looking at the given f={(2,4),(-4,3),(3,1/2),(π,3)} , when x =π then y=3
So, f(π) = 3
9.) In a state with a sales tax of 7%, Hernando
spends a total of $73.98. What is the final price
after tax that Hernando has to pay? Show work.
Answer:
Final price = $79.16
Step-by-step explanation:
Given that:
Sales tax in the state = 7%
Amount spent by Hernando = $73.98
Amount of sales tax = 7% of 73.98
Amount of sales tax = [tex]\frac{7}{100}*73.98[/tex]
Amount of sales tax = 0.07 * 73.98
Amount of sales tax = $5.18
Final price = 73.98 + 5.18 = $79.16
Hence,
Final price = $79.16

Using the coordinate plane below, find the distance between each pair of points. 1. (-3, 6) and (-3, 10) 2. (4, -5) and (-2, -5) 3. (6, 4) and (6, -1) 4. (-9, 1) and (-4, 1)
Answer:
1. 4
Step-by-step explanation:
(-3, 6) and (-3, 10)
|-3 - 3| = 0, |6 - 10| = 4
4² + 0² = 16, [tex]\sqrt{16}[/tex] = 4
(4, -5) and (-2, -5)
|4 - -2| = 6, |-5 - 5| = 0
6² + 0² = 36, √36 = 6
(6, 4) and (6, -1)
|6 - 6| = 0, |4 - -1| = 5
5² + 0² = 25, √25 = 5

A car travels 5/16 of a mile in 1/4 of a minute. How many miles will the car travel in 2 1/4 minutes?
Answer: 2 13/16 miles
Step-by-step explanation:
From the question, we are informed that a car travels 5/16 of a mile in 1/4 of a minute. The number of miles that the car will travel in 2 1/4 minute will be calculated as:
= 5/16 ÷ ( 1/4 / 2 1/4)
= 5/16 × 2 1/4 / 1/4
= 5/16 × (9/4 ÷ 1/4)
= 5/16 × 9
= 45/16
= 2 13/16 miles
The car will travel 2 13/16 miles in 2 1/4 minutes.
The cycle time for trucks hauling concrete to a highway construction site is uniformly distributed over the interval 40 to 75 minutes. What is the probability that the cycle time exceeds 50 minutes if it is known that the cycle time exceeds 45 minutes
Answer:
0.8333 = 83.33% probability that the cycle time exceeds 50 minutes if it is known that the cycle time exceeds 45 minutes
Step-by-step explanation:
A distribution is called uniform if each outcome has the same probability of happening.
The uniform distributon has two bounds, a and b, and the probability of finding a value higher than x is given by:
[tex]P(X > x) = \frac{b - x}{b - a}[/tex]
Uniformly distributed over the interval 40 to 75 minutes.
This means that [tex]a = 40, b = 75[/tex]
It is known that the cycle time exceeds 45 minutes
This means that we can use [tex]a = 45[/tex]
What is the probability that the cycle time exceeds 50 minutes?
[tex]P(X > 50) = \frac{75 - 50}{75 - 45} = 0.8333[/tex]
0.8333 = 83.33% probability that the cycle time exceeds 50 minutes if it is known that the cycle time exceeds 45 minutes
What expressions represent 1/3 times the sum of 8 and 4
Answer:
1/3 * (8 + 4)
Step-by-step explanation:
Expression which represents 1/3 tines the sum of 8 and 4
Expressing mathematically,
Sum of 8 and 4 is written as (8 + 4)
1/3 of the sum is expressed as ; 1/3 x (8 + 4)
Hence,
1/3 * (8 + 4)
1/3 * 12
= 4
Expression is 1/3 * (8 + 4)
Result = 4

Diane had 0.9 grams of pepper. Then she used 0.6 grams of the pepper to make some scrambled eggs. How much pepper does Diane have left? 10min left!!!!!!!!!!!!!!!!!!!!!!!!!!!
Answer:
Diane had 0.3 grams of pepper left
Step-by-step explanation:
If she had 0.9 grams of pepper, we can subtract the amount of pepper she used (0.6) to find out how much she has left.
0.9 - 0.6 = 0.3
(sorry if this is confusing but I hope it helped)

If the volume of a box if found by calculating the product of its length, height and width, then which of
the following statements below explain the volume of a box represented by function V(x) = x* (10 -
4x) and correctly interpreted V (2)?
A
Given the length, the height, and the width of the box, it was a perfect cube. V(x) is a cubic
function for volume of the box with sides measuring 2 units, where V(2) = 8.
B
Given the length of x, the height of 2x, and the width of 10 - 4x of the box, V(x) is a cubic
function for the volume of the box, where V (2) = 16.
C Given the length, the height, and the width of the box, 2 of the dimensions were the same. V(2)
is a cubic function for the volume of the box with 2 sides measuring 2 units, where V (2) = 8.

Translate and solve: Eighty-Two less than r is less than −164.
Give your answer in interval notation.
Answer:
(−∞,−82)
Step-by-step explanation:
Eighty-two less than r, r−82 is less than <−164.
Now we can solve the inequality by adding 82 to each side.
r−82r−82+82r<−164<−164+82<−82
In interval notation, we write this as (−∞,−82).
The value of r in the statement eighty-Two less than r is less than −164
is r < - 82.
What are inequalities and their types?Inequality is a relation that compares two numbers or other mathematical expressions in an unequal way.
The symbol a < b indicates that a is smaller than b.
When a > b is used, it indicates that a is bigger than b.
a is less than or equal to b when a notation like a ≤ b.
a is bigger or equal value of an is indicated by the notation a ≥ b.
The given statement is Eighty-Two less than r is less than −164 which can be numerically expressed as,
r - 82 < - 164.
r < - 82.
