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%
i’ll give u brainliest!! what is the area of shape 1 2 and 3
Answer:
Shape 1: 197.04
Shape 2: 125.44
Shape 3: 62.72
Step-by-step explanation:
For shape 1, you first need to find the radius to then find the area of a circle. Which is 394.08. Since this isn't a full circle, you will need to divide it by 2 to get 197.04. For shape 2(Easiest to find) You do 11.2*11.2 to get the answer of 125.44. And lastly for shape 3, you can basically do the same as what you did for shape 2. But since it is a triangle, you divide your answer by 2, to get the answer of 62.72.

Evaluate the function:
f(x)=x2−4x, find f(−3)
Answer:
f(-3) = 21
Step-by-step explanation:
To solve this, you can replace all x's with -3 and then solve to find the answer.
f(x) = x^2 - 4x
f(-3) = -3^2 - 4(-3)
f(-3) = 9 - (-12)
f(-3) = 21

Answer: Option A.
Step-by-step explanation:
Simplifying
xy + -9z = 4
Solving
xy + -9z = 4
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '9z' to each side of the equation.
xy + -9z + 9z = 4 + 9z
Combine like terms: -9z + 9z = 0
xy + 0 = 4 + 9z
xy = 4 + 9z
Divide each side by 'y'.
x = 4y-1 + 9y-1z
Simplifying
x = 4y-1 + 9y-1z
In a system of two linear equations, the lines represented by each equation have the same slope. Which could be the total number of solutions to the system of equation
Answer:
Please see explanation
Step-by-step explanation:
A system of linear equations in two variables represents two lines on graph.
When both the lines have same slope, there can be two cases
Same slope with different y-interceptsWhen two lines have same slope and different y-intercepts, that means that both lines are parallel and parallel lines have no solution.
Same slope with same y-interceptsWhen the slope of both lines is same and the y-intercept is also same, this means that both the equations refer to the same line. This means that the system has infinite number of solutions.

Gia opened two savings accounts at two diffrent banks. One account earns an annual 3.4% simple interest, and the other earns half as much. If she deposited $509 in each account, how much total interests will sh have earned in 3 years? A:$153.00 B:$38.25 C:$76.50 D:$51.00
Interest from first account is :
[tex]I_1 = \dfrac{p\times r \times t}{100}\\\\I_1 = \dfrac{509\times 3.4\times 3}{100}\\\\I_1 =\$ 51.918[/tex]
Interest form second account is :
[tex]I_2 = \dfrac{p\times r\times t}{100}\\\\I_2 = \dfrac{509\times 1.7\times 3}{100}\\\\I_2 = \$25.959[/tex]
So, total interest is :
[tex]I = I_1 + I_2 \\\\I = 51.918 + 25.959\\\\I = \$77.877[/tex]
Therefore, total interest is $77.877 .

what is the value of 4(2f-3d)+2(2d+e)
Answer:
8f - 8d + 2e
Step-by-step explanation:
8f-12d+4d+2e = 8f - 8d + 2e
Answer:
−8d+8f+5.436564
Step-by-step explanation:
Let's simplify step-by-step.
4(2f−3d)+2(2d+2.718282)
Distribute:
=(4)(2f)+(4)(−3d)+(2)(2d)+(2)(2.718282)
=8f+−12d+4d+5.436564
Combine Like Terms:
=8f+−12d+4d+5.436564
=(−12d+4d)+(8f)+(5.436564)
=−8d+8f+5.436564
Answer:
=−8d+8f+5.436564

find common denominator
For [tex]\dfrac{1}{3}-\dfrac{1}{6}[/tex] the fraction will be [tex]\dfrac{1}{6}[/tex] .
Given to us,
[tex]\dfrac{1}{3}-\dfrac{1}{6}[/tex]
To solve this, firstly we need to make the denominators the same, thus taking the LCM of both 3 and 6.
As we know the LCM of 3 and 6 is 6 itself.
So, multiplying and dividing by 2.
[tex]\dfrac{1}{3}\rightarrow \dfrac{1\times 2}{3\times 2}\rightarrow \dfrac{2}{6}[/tex]
Now,
[tex]\dfrac{2}{6}-\dfrac{1}{6} = \dfrac{1}{6}[/tex]
Hence, for [tex]\dfrac{1}{3}-\dfrac{1}{6}[/tex] the fraction will be [tex]\dfrac{1}{6}[/tex] .
