Answer:
18
Step-by-step explanation:
The middle number of the sequence us the median
Answer:
7. Mean = 48
Median = 47.5
Mode = 72
Range = 66
8. Mean= 59.625
Median = 61
Mode = 90
Range = 79
9. Mean = 31.57
Median = 32
Mode = 46
Range = 34
10. Mean = 42.11
Median = 36
Mode = 51
Range = 51
Step-by-step explanation:
Mean is the average. Mode is the number that appears the most. Median is the middle number. Range is the biggest number minus the smallest number.
Hope this helps.
Answer:
7. Mean = 48
Median = 47.5
Mode = 72
Range = 66
8. Mean= 59.625
Median = 61
Mode = 90
Range = 79
9. Mean = 31.57
Median = 32
Mode = 46
Range = 34
10. Mean = 42.11
Median = 36
Mode = 51
Range = 51
Step-by-step explanation:
The solution to the equation 2(12 - 8x) = x - 11x is x = -4.
To solve the equation 2(12 - 8x) = x - 11x, we can simplify and solve for x by following these steps:
Distribute the 2 to the terms inside the parentheses:
24 - 16x = x - 11x
Combine like terms on the right side of the equation:
24 - 16x = -10x
Bring all the x terms to one side of the equation:
-16x + 10x = -24
-6x = -24
Divide both sides of the equation by -6 to isolate x:
x = 24 / 6
Simplifying the division, we get:
x = 4
Therefore, the solution to the equation 2(12 - 8x) = x - 11x is x = -4.
By performing the necessary operations of distribution, combining like terms, and solving for x, we have determined that -4 satisfies the equation. Substituting x = -4 back into the original equation confirms that both sides are equal.

The answer to that is 2.875
To find the ratio of mystery books to the total, divide the number of mystery books by the total number of books and simplify the ratio if possible.
To find the ratio of mystery books to the total, we need to divide the number of mystery books by the total number of books and simplify the ratio if possible.
In this case, the number of mystery books is 12 and the total number of books is 48. So, the ratio of mystery books to the total is 12:48.
We can simplify this ratio by dividing both the numerator and denominator by 12. This gives us a simplified ratio of 1:4.
