To answer this question we can propose the following equation:
Where:
x is the number of weeks elapsed.
d is the debt depending on the weeks.
Robert promised to pay at least $ 67 each week.
Therefore, after 5 weeks the debt of rober should be:
Then scenario A) is possible because .
After 6 weeks:
Then scenario B) is possible because .
After 7 weeks
Then scenario C) is possible because .
After 8 weeks
So scenario D) is NOT possible because
Finally the correct answer is option D.
Range= biggest number - smallest number
so,
67 - 39 = 28
Answer:
A) Length = 94 m
B) Width = 79 m
Step-by-step explanation:
A)
The area of a parking lot is 7802 m²
Area = length x width
7802 = length x 83
length = 7802 ÷ 83
length = 94 m
b)
The perimeter of a pool is 353 m
Perimeter = 2(length + width)
352 = 2(97 + width)
352 = 194 + 2width
2width = 352 - 194
2width = 158
width = 158/2
width = 79 m

Answer:
18.5 in=decimal feet,
Step-by-step explanation:
1)18.5/12=18.512
2)18.512=1.542 feet
Standard deviation is like the average range values are away from the mean/median. So if you remember box and whisker plots, It is 2 boxes with 2 lines coming from them. Where the boxes meet is the mean/median depending on what you are trying to find, and the edges of the boxes are the normal distribution of values, and the lines go out, and that's the standard deviation. The values outside of those lines are outliers. A way you can think about it, is if let's say I had 3 numbers: 7,8,9. Now the mean/median is 8, and for this the standard deviation is 1 because most numbers that are not the median/mean are 1 value from the median/mean. It is a way of measuring an element of range. I hope this helped.
