Answer:
C. $0.0004
Step-by-step explanation:
Cost per cubic foot is found by dividing the cost by the number of cubic feet of volume the space has. Of course, the volume is the product of the dimensions, so we have ...
cost per ft³ = $1500/((250 ft)(300 ft)(50 ft)) = 15×10²/(3.75×10⁶) $/ft³
= 4×10⁻⁴ $/ft³ = $0.0004 per cubic ft
Kilograms. Everything else is too high
Answer:
B:
Step-by-step explanation:
Measure of ARC AFB is 180°
Why?
This is because AB is a diameter.
Basically make a plot that has no correlation (the points are all random and don't mean anything)
Answer:
The z-score for a data value of 121 is -2.29.
Step-by-step explanation:
In a set with mean
and standard deviation
, the zscore of a measure X is given by:

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this problem, we have that:

Find the z-score for a data value of 121.
This is Z when X = 121. So



The z-score for a data value of 121 is -2.29.
