Answer:
-2, -6
Step-by-step explanation:
|3x−4(x+1)|=2
|3x - 4x - 4| = 2
|-x - 4| = 2
-x - 4 = 2
-x = 6
x = -6
-x - 4 = -2
-x = 2
x = -2
Answer:
Step-by-step explanation:
Given that X - the distribution of heights of male pilots is approximately normal, with a mean of 72.6 inches and a standard deviation of 2.7 inches.
Height of male pilot = 74.2 inches
We have to find the percentile
X = 74.2
Corresponding Z score = 74.2-72.6 = 1.6
P(X<174.2) = P(Z<1.6) = 0.5-0.4452=0.0548=5.48%
i.e. only 5% are below him in height.
Thus the malepilot is in 5th percentile.
A=11. to graph it plot an open circle on 11 and go right
25 - 5= 20
20/25 = 0.8
0.8*100 = 80
Percent change is 80%
Answer:
