A traffic engineer records a sample of the types of vehicles that cross a bridge. She counts 112 passenger cars, 18 light trucks, and 20 heavy trucks.
What is the APPROXIMATE probability that a random vehicle crossing the bridge is a passenger car?
Answer:
The approximate probability that a random vehicle is a passenger car is 74.67%
Step-by-step explanation:
Probability
The traffic engineer records 112 passenger cars, 18 light trucks, and 20 heavy trucks. The total of vehicles recorded is n=112+18+20 = 150.
We are required to find the probability that a randomly selected vehicle crossing the bridge is a passenger car. There are 112 passenger cars, thus the probability is:
[tex]\displaystyle p=\frac{112}{150}[/tex]
p = 0.7467
p = 74.67%
The approximate probability that a random vehicle is a passenger car is 74.67%
The video streaming service that you want to use is represented with the equation below, where y represents the the total monthly cost of the service and x represents the number of videos you plan to stream each month:
y = $1.25x + $5.00
What is the total cost of the service for the month if you stream 30 videos?
Group of answer choices
$36.25
$151.25
$35.00
$42.50
Answer:
$42.50
Step-by-step explanation:
y = mx + b
x = how many videos you watched
y = 1.25(30) + 5.00 = 42.50

On average, Emma can clean her room in 35 minutes but, depending on how dirty her room is, her time can vary from the average by 20 minutes.
Which absolute value equation can be used to calculate Emma's maximum and minimum time to clean her room?
Let x represent the maximum and minimum time.
|x-20|=35
|x+20|=35
|x+35|=20
|x-35|=20
B. |x+20|=35
This is because 20 is the minimum time, so you have to add that to whatever x is. since x can be the minimum or maximum, this further proves this statement. You can also know this is correct because the final product (35) was the maximum time shown in the world problem
May I have brainliest please? :)
Find the midpoint of the line segment with end coordinates of:
(-3,-1) and (-4,2)
Answer:
(- 3.5, 0.5 )
Step-by-step explanation:
Given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is
( [tex]\frac{x_{1}+x_{2} }{2}[/tex], [tex]\frac{y_{1}+y_{2} }{2}[/tex] )
Here (x₁, y₁ ) = (- 3, - 1) and (x₂, y₂ ) = (- 4, 2) , then
midpoint = ( [tex]\frac{-3-4}{2}[/tex], [tex]\frac{-1+2}{2}[/tex] ) = ( [tex]\frac{-7}{2}[/tex], [tex]\frac{1}{2}[/tex] ) = (- 3.5, 0.5 )

Answer:
x = 8, y = 8[tex]\sqrt{3}[/tex]
Step-by-step explanation:
30-60-90 triangles have sides in a ratio of 1 : [tex]\sqrt{3}[/tex] : 2
'x' would be half of 16, or 8
'y' would be x · √3, or 8[tex]\sqrt{3}[/tex]

2x+8y=56 on a 10x 10 grid
Answer:
Step-by-step explanation:
Simplifying
2x + -8y = 56
Solving
2x + -8y = 56
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '8y' to each side of the equation.
2x + -8y + 8y = 56 + 8y
Combine like terms: -8y + 8y = 0
2x + 0 = 56 + 8y
2x = 56 + 8y
Divide each side by '2'.
x = 28 + 4y
Simplifying
x = 28 + 4y
2x + 3 = 5 what does x equal?
Answer:
x=1
2x+3=5

now the three gets canceled and 5-3 is 2
2x=2
now divide 2 on both sides
2x÷2=2÷2
x=1
