Answer:
-512
Step-by-step explanation:
Evaluate y^5/(x^3/2^2) where x = 2 and y = -4:
(y^5)/(2^(-2) x^3) = (-4)^5/2^(-2)×1/2^3
2^3 = 2×2^2:
(-4)^5/2^(-2) 1/(2×2^2)
2^2 = 4:
(-4)^5/((2×4)/2^2)
2×4 = 8:
(-4)^5/(8/2^2)
2^(-2) = 1/4:
((-4)^5/8)/(1/4)
(-4)^5 = (-1)^5×4^5 = -4^5:
((-4^5)/8)/(1/4)
4^5 = 4×4^4 = 4 (4^2)^2:
((-4 (4^2)^2)/8)/(1/4)
4^2 = 16:
((-4×16^2)/8)/(1/4)

2 | 5 | 6:
((-4×256)/8)/(1/4)
4×256 = 1024:
((-1024)/8)/(1/4)
Multiply the numerator by the reciprocal of the denominator, ((-1024)/8)/(1/4) = (-1024)/8×4:
(-1024×4)/8
(-1024)/8 = (8 (-128))/8 = -128:
-128×4
-128×4 = -512:
Answer: -512
You would need to add 10 -oz with 14-oz and once you get that answer,you need to add it to 40-oz
That would be (4/6) of 45 minutes, or 180/6 minutes, or 30 minutes.
You could also find her rate: 6 miles / 45 minutes, or 8 miles / 60 minutes.
Write an equation of ratios:
8 mi 4 mi
---------- = ------------
60 min x
Solving for x: 8x = 240; x = 30 minutes
Answer:
Mean

Best measure of center
The mean is considered the best measure of center when there are no outliers in the given data.
Outlier is when a particular data set is far away from other datasets.
For instance: 20 is an outlier in the following data sets:
Also, the given data are not open-ended.
An open-ended data is as follows:
Since we do not have any of the above conditions, then the mean is the best center to use.
