Answer:
Step-by-step explanation:
<em>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.</em>
<em />
<em>Height of male pilot = 74.2 inches</em>
<em />
<em>We have to find the percentile</em>
<em />
<em>X = 74.2</em>
<em />
<em>Corresponding Z score = 74.2-72.6 = 1.6</em>
<em />
<em>P(X<174.2) = P(Z<1.6) = 0.5-0.4452=0.0548=5.48%</em>
<em />
<em>i.e. only 5% are below him in height.</em>
<em />
<em>Thus the malepilot is in 5th percentile.</em>
Answer: Pt1= Only x=5
Pt2=Is not x=5 is an extraneous solution though I believe It is x=-2 is an extraneous solution

Step-by-step explanation:
Find the area of the base
The base is a square.
The formula is Area = s^2
s = 1.5
Area = 1.5^2
Area = 2.25 sq cm.
Area of 1 triangle
h = 2.4
b = 1.5
Area = 1/2 * b * h
Area = 1/2 * 1.5 * 2.4
Area = 1.8 cm^2
Area of 4 triangles
Area = 4 * area of 1 triangle
Area = 4 * 1.8
Area = 7.2
Total Area = 2.25 + 7.2 = 9.45 cm^2
