Answer:
The 99th percentile for a man’s arm span is 80.47 inches.
Step-by-step explanation:
Problems of normally distributed samples can be solved using the z-score formula.
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:
99th percentile
X when Z has a pvalue of 0.99. So X when Z = 2.327.
The 99th percentile for a man’s arm span is 80.47 inches.
Plotting the functions is highly recommended.
For A, the area under 
over the interval [1, 2] is the area of rectangle with height 3 and width 2 - 1 = 1, so the area is
For B, the area under 
plotted over the interval [0, 2] is the area of a triangle with height 1 and base length 2, so the area is
Answer:
-5
Step-by-step explanation:
if u add negative and positive of the same numbers the end result is 0
Answer: >, <, ≥, ≤
Step-by-step explanation: Any of these are clear indicators of an inequality
Step-by-step explanation:
1.) Plug in one of the points.
y = 8x + b
6 = 8(4) + b
2.) Solve for b (or [?])
32 cancels out on the right side.
Subtract 32 from 6, which is -26
3.) -26 = b
4.) Check with other point:
-2 = 8(3) + b
-2 = 24 + b
Cancel out 24 on the right side: 24-24 = 0
-2 - 24 = -26
-26 = b
