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.

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

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

Charlie and Violet met for lunch at a restaurant between their two locations (exactly in the middle). It took
Charlie 2.6 hours to get there, but it only took Violet two hours because she was driving 15 mph faster than
Charlie. The distance between the two of them initially was 260 miles. Find the speed of the two drivers.
Charlie
Violet
mph
mph
Answer:
Charlie 55 miles per hour
Violet 65 miles per hour
Step-by-step explanation:
Charlie and Violet met for lunch at a restaurant between Memphis and New Orleans. Since, Charlie left Memphis and drove towards New Orleans, and Violet left New Orleans and drove towards Memphis, the total distance that they covered altogether is the total distance between Memphis and New Orleans.
It is given that the distance between Memphis and New Orleans is 394 miles. This means, the total distance both covered = 394 miles
Charlie drove for 4.8 hours and Violet drove for 2 hours. Let the speed of Charlie be x miles per hour. Since, the speed of Violet was 10 miles per hour faster than Charlies, the speed of charlie was (x + 10) miles per hour
Since, distance = speed multiplied by time
Distance covered by Charlie = 4.8x
Distance covered by Violet = 2(x + 10)
Altogether they covered 394 miles,
So,
394 = Distance covered by Charlie + Distance covered by Violet
394 = 4.8x + 2(x + 10)
394 = 4.8x + 2x + 20
374 = 6.8x
x = 55
Since, x represents the speed of Charlie, the speed of charlie was 55 miles per hour and speed of Violet was 65 miles per hour
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.
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.
