The answer is c cccccc the answ er is c
Mean= is the summation of the maximum temperatures ÷ the numbers of times the temperatures where recorded
standard deviation= is a number used to tell how measurements for a group are spread out from the average (mean), or expected value.
A low standard deviation means that most of the numbers are very close to the average.
A high standard deviation means that the numbers are spread out.
Variance= is a way to measure how far a set of numbers is spread out.
A variance of zero indicates that all of the data values are identical. All non-zero variances are positive.
A small variance indicates that the data points tend to be very close to the mean, and to each other.
A high variance indicates that the data points are very spread out from the mean, and from one another.
Answer:
874.6
Step-by-step explanation
Profit = Sales - Costs
Profits by day:
Mon:
225 - (225*0.12) -9 = 189.0
Tue
260 - (260*0.12) -9 = 219.9
Wed
230 - (230*0.12)-9 = 193.4
Thu
180 - (180*0.12) - 9 = 149.4
Fri
150 - (150*0.12) -9 = 123.0
Total:
189+219.9+193.4+149.4+123 = 874.6
8x8x8=512

What is the slope of the line through (-7,-8)(−7,−8)left parenthesis, minus, 7, comma, minus, 8, right parenthesis and (0,4)(0,4
ANEK [815]
Answer:
12/7
Step-by-step explanation:
When given two points, we can find the slope by using
m = (y2-y1)/(x2-x1)
= (4 - -8)/ (0 - -7)
= (4+8) / (0+7)
= 12/7
