Given:
μ = 55 in, population mean
σ = 6 in, population standard deviation
Part (a)
x = 48 in, the random variable
Calculate the z-score.
z = (x - μ)/σ
= (48 - 55)/6
= -1.667
From standard table, obtain
P(X < 48) = 0.12167
Answer: 0.1217 (tyo 4 dec.places)
Answer:
YZ cannot be determined from the similar triangles
Step-by-step explanation:
Given two similar triangles, to get any sides of the triangles, the ratio of their congruent sides is equal to a constant, Hence;
AB/XY = AC/XY
Also, BC/YZ = AB/XY
This shows that to get YZ, both BC and XY must be given. Since we are not given either of the two sides hence YZ cannot be determined from the similar triangles
Answer:
Perimeter = 4s
s = P/4
s = 48 in/4
s = 12 in
V = a^2h/3
h = 3V/a^2
h = 3(288 in^3)/ (12 in)^2
h = 864 in^3 / 144 in^2
h = 6 inches
