Find the probability that an adult resident has 3 or more
vehicles. Give your answer as a number between 0 and 1.

Answers

Answer:

Step-by-step explanation:

Number of Vehicles Probability

0 0.04

1 0.41

2 0.38

3 0.13

4 0.03

5 0.01

X= 1

.13+.03+.01=0.17 (the amount with 3 or more cars)  

0.17/1(Total amount of all probability)= 0.17 has 3 or more cars.

Probability is the chance of an event to occur from a total number of outcomes.

The formula for probability is given as:

Probability = Number of required events / Total number of outcomes.

The probability that an adult resident has 3 or more is 0.17

What is probability?

It is the chance of an event to occur from a total number of outcomes.

The formula for probability is given as:

Probability = Number of required events / Total number of outcomes.

We have,

The probability distribution of the number of vehicles is given as,

P(x) where x is the number of vehicles.

P(0) = 0.4

P(1) = 0.41

P(2) = 0.38

P(3) = 0.13

P(4) = 0.3

P(5) = 0.1

The probability that an adult resident has 3 or more.

= P(3) + P(4) + P(4)

= 0.13 + 0.03 + 0.01

= 0.17

Thus,

The probability that an adult resident has 3 or more is 0.17

Answer:

-7

Step-by-step explanation:

right on edge 2021

The determinant of the provided matrix is -7 after opening the matrix option (B) -7 is correct.

What is the matrix?

It is defined as the group of numerical data, functions, and complex numbers in a specific way such that the representation array looks like a square, rectangle shape.

It is given that a matrix:

[tex]\rm H = \left[\begin{array}{ccc}0&2&3\\-1&3&5\\6&3&-2\end{array}\right][/tex]

As we know, the determinant in arithmetic is a real number that is a variable of the rows and columns of a square matrix. It lets specifying a few aspects of the matrix and the linear map that the matrix provides.

Open the above matrix to find the determinant:

|H| = 0[(-6 - 15)] - (-1)[-4 - 9] + 6[10 - 9]

|H| = 0[-21] - (-1)[-13] + 6[1]

|H| = 0 - 13 + 6

|H| = -7

Thus, the determinant of the provided matrix is -7 after opening the matrix option (B) -7 is correct.

Calculate the area of the triangle:

A. 48 square units
B. 14 square units
C. 24 square units
D. 10 square units

HELP ME PLS PLS ASAP PLS PLZ PLS

Answers

Answer: C

Step-by-step explanation: 8(6)=24

C. 24, because to find the area of a triangle you need to multiply the two lengths and then find the half of it. So in this case, it would be 8x6=48, and half of 48 is 24.

The area of a rectangular sheet of metal is 135 square inches. The perimeter is 48 inches. What are the dimensions of the sheet?

Answers

Answer:  The length is 15 inches and breadth is 9 inches

Step-by-step explanation:

Given : Area of rectangular sheet = 135 square inches

Perimeter of rectangular sheet = 48 square inches

Now Area of rectangular sheet = [tex]Length\times Breadth[/tex] =  135 square inches

perimeter of rectangular sheet = [tex]2\times (Length+Breadth)[/tex] = 48 square inches

Thus [tex](Length+Breadth)[/tex] = 24 square inches

Thus Length = 15 inches

Breadth = 9 inches

Which of the following statements is NOT true about the graph of a system of equations with no solutions?

A. The lines will have the different slopes.
B. The lines will have different y-intercepts.
C. The lines will share none of the same points.
D. The lines will have the same slope.

Answers

Answer:

A

Step-by-step explanation:

A would be the best answer here because equations with no solutions would be parallel. That means they would have the same slope but with different y-intercepts. Since where the equations share points would be the solution, they cannot share points either.
