Area of the room = 14*15 = 210 ft^2
Cost padding = 210*89 = 186.90
Cost of carpet = 210 * 2.99 = 627.90
Perimeter of the room = 2*15 + 2*14 = 58 ft
Cost of strip = 58*0.19 = 11.02
Total cost of supplies = 186.90 + 627.90 + 11.02 = 825.82 Answer
Answer:
the percent error is 6.25%
Step-by-step explanation:
The computation of the percent error is shown below:
Percent error is
= (Experimental value - accepted value) ÷ (experimental value) × 100
= (80 degrees - 75 degrees) ÷ (80 degrees) × 100
= (5 degrees) ÷ (80 degrees) × 100
= 0.0625 × 100
= 6.25%
hence, the percent error is 6.25%
We simply applied the above formula so that the correct value could come
And, the same is to be considered
Answer:the answer would be 75
Step-by-step explanation:If you divide 105 by 7 you get 15 which mean there are 15 strawberries per box so just take 15 times 5 to get your answer -hope this helps!
Answers:
Sample Variance = 31.03
Sample Standard Deviation = 5.57
See the table below.
===================================================
Explanation:
M refers to the midpoint of each interval. The midpoint is
where a,b are the left and right endpoints.
For example,
in the first row.
Multiply the frequency with the midpoint to get the third column. Summing this column of values leads to 4+49+180+153+154 = 540 shown at the bottom of that column.
Divide this sum over the sum of the frequencies (2+7+15+9+7 = 40) and we arrive at
which is the sample mean xbar.
--------------------------------------------------------------------------
After we determine xbar, we subtract it from each value of M. Then we square the result to get
. Multiply that with the column f to get the new column
.
This column is added to arrive at 1210 shown in the table below. Divide this over the sum of the frequencies minus 1. So we divide by n-1 = 40-1 = 39 to get roughly 31.03
This is the sample variance.
The square root of this is sqrt(31.03) = 5.57 and this is the approximate sample standard deviation.
