Answer:
12.3 grams
Step-by-step explanation:
When a constant value is added to each data element in a distribution, the maen changes by that constant but the standard deviation stays the same. This is because the standard deviation is a measure of how distant the data are from the mean. When a constant value is added to each of them, the mean also gets the increment. Hence, the distance from the mean is maintained.
However, if the data were multiplied by a constant factor, then the standard deviation will be multiplied by the same factor as well as the mean.
Therefore, the standard deviation from the question remains the same as before, 12.3 grams.
Answer:
m=75
Step-by-step explanation:
75/-5=-15
Answer:
22
Step-by-step explanation:
Use the trapezoid area formula.
A = (b1 + b2) / 2 * h
Plug in the values.
A = 3 + 8 / 2 * 4
A = 11 / 2 * 4
A = 44/2
A = 22
P = l + w + l + w or 2l + 2w
answer is A. first one.
Answer:
1 1/6 units
Step-by-step explanation:
area = length * width
6 * 1 1/6 = 7
