Answer:
63 pounds
Step-by-step explanation:
Given data
Quantity of meat= 18 pounds
TIme taken= 2 hours
Rate= Quantity/Time taken
Rate= 18/2
Rate= 9 pounds per hour
Now time= 7 hours
Rate= 9 pounds per hour
Quantity= Rate*Time
Quantity= 9*7
Quantity= 63 pounds
It is the biggest number that two numbers are divisible by.
For example, if you did 12 and 24
The factors of 12 are:
1, 2, 3, 4, 6, 12
The factors of 24 are:
1, 2, 3, 4, 6, 8, 12, and 24
Their greatest common factor would be 12 since, it is the greatest number that each number can be divisible by.
The matrix expressions are:
- Matrix 2 cannot be solved
<h3>How to solve the matrix expression?</h3>
The rule for matrix product states that:
If the dimensions of matrix A is m by n, and the dimension of matrix B is n by p.
Then, the dimension of the product matrix is: m by p
Using the above rule, we have:
<u>Expression 1:</u>
Expand:
By comparison, we have:
12a + 7c = 2
5a + 3c = 3
12b+ 7d = -1
5b + 3d = 2
Using a graphing tool, we have:
a = -15, b = -17, c = 26 and d = 29
Hence, the matrix expression is:
<u>Expression 2:</u>
Expand:
By comparison, we have:
6.75a + 3b = 8
-9a - 4b = 5
Using a graphing tool, the system of equation has no solution
Hence, the matrix expression cannot be solved
<u>Expression 3:</u>
Expand:
By comparison, we have:
-2a + 3b = 6
3a + 5b = 8
Using a graphing tool,
a = 3 and b = 4
Hence, the matrix expression is:

I do believe the answer is D
To make A frequency table, you will need to look at the lowest average number of movies and the highest average number of movies and create equally space intervals.
You will need to include 0.5 to 4.5.
I would use the following equal intervals (frequencies are beside the intervals).
0 - 0.9(1)
1 - 1.9(5)
2 - 2.9(5)
3 - 3.9(2)
4 - 4.9(1)
Check to make sure they are all there by counting the frequencies. The total should equal the number of pieces of data that you had to start with.
