Answer:
The value of x is about 2.206.
Step-by-step explanation:
Consider the given equation is
We need to find the value of x.
Using the properties of logarithm we get
On comparing both sides we get
Using graphing calculator, the real solution of the above equation is
Therefore, the value of x is about 2.206.
Answer: 0.206
Step-by-step explanation:
Given that :
Height of American men is normally distributed :
Mean height (μ) = 69.7 inch
Standard deviation (σ) = 2.8 inch
Probability that height of a randomly selected man is more than 72 inches
P(X > 72)
Obtain the standardized score (Zscore):
Zscore = (x - μ) / σ
Zscore = (72 - 69.7) / 2.8
Zscore = 2.3 / 2.8
Zscore = 0.8214285
Zscore = 0.8214
Using the Z probability calculator ;
P(Z > 0.8214) = 0.20571
Probability of selecting a man whose height is more Than 72 is 0.206
Answer:
Area = 1/2 × base × height
A = 1/2 × 5 × 3,3/5
= 9
