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
Here is the answer to the problem above. Given that a necktie is sold per dozen and costs $30.00 and sells it for $5. In order for us to know the price per necktie, we just have to divide 30 by 12 since one dozen is 12. 30 divided by 12, and the answer is 2.5. So the cost of one tie is $2.5. Hope this answers your question.
x>12
When someone is older than 12, their age is greater than 12.
Answer:
1/4
Step-by-step explanation:
10+10+20=40
10 of those are red cards which makes it 10/40 which is simplified to 1/4.
In order from least to greatest ---- -2.15, -2.105, 17/7, 2.7
