Men’s heights are normally distributed with a mean of 71.8 inches and a standard deviation of 3.4 inches. A social organization
nadya68 [22]

Answer: 2.28%

Step-by-step explanation:

μ = 71.8

σ = 3.4

X < 65

P(X < 65) = P (Z < 65 - 71.8/3.4) = P (Z < -2)

According to the table for the normal distribution attached, it will give us

P (z < Z < 0), this way, to find the P(Z < z), we need to do 0.5 - P:

0.5 - P(-2 < Z < 0) = 0.5 - 0.4772 = 0.0228

In percentage: 0.0228*100 = 2.28%

What is the length of ED
STALIN [3.7K]

Answer:

ED ≈ 2.6 units

Step-by-step explanation:

Using the Sine rule in Δ DEF

\frac{FD}{sin115} = \frac{ED}{sin20}

\frac{6.95}{sin115} = \frac{ED}{sin20} ( cross- multiply )

ED sin115° = 6.95 sin20° ( divide both sides by sin115° )

ED = \frac{6.95sin20}{sin115} ≈ 2.6 ( to the nearest tenth )

HELP!!!!!!!!!! AP CALCULUS AB
raketka [301]

Answer:

\lim_{x \to 5^{-}} f(x)= 54

\lim_{x \to 5^{+}} f(x) = -17

Step-by-step explanation:

+ means we are approaching from the right

- means we are approaching from the left

We are given that if x < 5, it is x² + 5x + 4

So to find \lim_{x \to 5^{-}} f(x) we would plug in 5 into that piecewise function part:

5² + 5(5) + 4 = 54

We would be approaching y = 54 if we approach from the left.

We are given that x > 5, it is -4x + 3

So to find \lim_{x \to 5^{+}} f(x) we would plug in 5 into that piecewise function part:

-4(5) + 3 = -17

We would approach y = -17 if we approached from the right.
