Answer:
98
Step-by-step explanation:
the measure of angles of a triangle=180
the measure of straight angle=180 find angle HAC:
180-128=52
angle A: 180-52-46= 82
now find IAC : 180-82=98 degrees
Answer:
Step-by-step explanation:
Given that taxi Fares are normally distributed with a mean fare of $22.27 and a standard deviation of $2.20.
For a random single taxi std deviation is 2.20
But for a sample of size 10, std deviation would be

This would be less than the 2.20
Because std devition is less for sample we get a big z score for the sample than the single.
As positive values of z increase we find that probability would decrease since normal curve is bell shaped.
So single taxi fare would have higher probability than sample.
B) Here >24.
By the same argument we have z value less for single taxi hence the probability for more than that would be less than that of sample size 10
Answer:
34:49
Step-by-step explanation:
total = 49 plays
comedy + tragedies is 20 + 14 = 3
So the odds of picking a tragedy or comedy is 34:49
