The answer is <span>B. 14(m − 8)
</span>
<span>m represent the weight of the boxes that Marco lifted.
</span><span>d represent the weight of the boxes that Drew lifted.
</span><span>The boxes that Drew lifted each weighed 8 lb less than the boxes Marco lifted:
d = m - 8
So the weight of one box that Drew lifted is (m - 8). Since he lifted boxes, the </span><span>total number of pounds Drew lifted is </span> 14(m - 8)
Answer:
A.) The manager calculated mean and not standard deviation
B.) Standard deviation should be calculated with the use of formula.
Step-by-step explanation:
A.) The assumption that his customers do spend more than the national average is wrong because the standard deviation is not calculated and mean cannot be used as a substitute for standard deviation.
B.) Standard deviation tells us how value obtain from group measurement deviates from the average value or expected value of each item of observations.
When standard deviation is low, this show that the value is very close to the expected value or the average value.
If the national average value = $150 and average customer spends $160.
Deviation = 160 - 150 = 10
This is lower than $30
Or better still, the manager should make use of standard deviation formula. Which is the square root of variance.

Answer:
Every number in the pattern will have a 0 or a 5 in its ones place
Step-by-step explanation:
Given
Rule: Divide by 2
See attachment for complete question
Required
Which statement is true
First, we apply the rule to complete the blanks.
Divide by 2 implies that we divide the current element by 2, to get the next
So, the first blank becomes
The next is:
So, we have:
Compare each option with the above dataset, we have:
(a) False; because 25 do not have 0 in its 1's space
(b) False; because 50 and 25 do not have 0 in their 10's space
(c) True; because each of the dataset either have 0 or 5 in their 1's space
