Answer:
(E) The z-scores of the height measurements
Step-by-step explanation:
Mean is given by

Where,
n = Number of people
= The heights of people
When converting m to cm the mean would be

So, the mean would change
The median gives us the middle data value when the data values are in ascending order.
So, the median would change
Standard deviation

When converting to centimeters

Hence, the standard deviation would change
When converting to centimeters the maximum height in meters would be the maximum height in centimeters also.
The z score is given by

where,
x = Data point
= Mean
= Standard deviation
When converting to centimeters

Hence, the z score would remain the same
Answer:

Step-by-step explanation:
Answer:
6
Step-by-step explanation:
4x-12 = x+7
4x-12+12 = x+7+12
4x = x+19
4x-x = x+19-x
3x=19
x = 6
And if we substitute the value of x into the equation 4x-12 = x+7,
we will get 13
= 13
in the end.

Answer: clearly the answer is B hope this helps
Step-by-step explanation:
Answer:
8x+25=5x+35 (x=10/3)
Step-by-step explanation:
The equation for Store A would be: y(cost) = 8x(days) + 25
The equation for Store B would be: y = 5x + 35
So, since he wants the cost to be the same, 8x+25=5x+35
