Box A is 4. 4 is 5% of the total boxes.
5% = 1/20, so multiply whatever number that's 5% of the total by 20 to get the total.
4 x 20 = 80.
There are 80 marbles total.
Hope this helps!
Answer:
7 pencils
8 sweet tarts
Step-by-step explanation:
7*0.35=2.45
8*0.10=0.80
2.45+0.80=3.25
7+8=15
=
Multiply both sides by v
<span>
= w Multiply both sides by x
</span>kv = wx Divide both sides by w
<span>
= x Switch the sides to make it easier to read
</span>
x = <span>

Answer:
14 and 22
Step-by-step explanation:
If x is the first number, then 36-x is the second. We are told that ...
2x -(36-x) = 6 . . . . twice the first less the second is 6
3x = 42 . . . . . . . . . add 36
x = 14
(36 -x) = 22
The numbers are 14 and 22.
Answer:
(a) MAE = 5.20
(b) MSE = 10
(c) MAPE = 38.60%
(d) Forecast for week 7 = 14
Step-by-step explanation:
Note: See the attached excel for the calculations of the Error, Error^2, and Error %.
(a) mean absolute error
MAE = Total of absolute value of error / Number of observations considered = |Error| / 5 = 26 / 5 = 5.20
(b) mean squared error
MSE = Total of Error^2 / Number of observations considered = Error^2 / 5 = 150 / 5 = 10
(c) mean absolute percentage error (Round your answer to two decimal places.)
MAPE = Total of Error % / Number of observations considered = Error % / 5 = 193.02 / 5 = 38.60%
(d) What is the forecast for week 7?
Since the forecast is based on the naive method (most recent value), the forecast for week 7 is value for week 6. Therefore, we have:
Forecast for week 7 = 14
