Answer:
Option D: g = 7 and h = 3
Step-by-step explanation:
The polynomial is;
8x² – 8x + 2 – 5 + x
Simplifying this gives;
8x² - 7x - 3
If this is simplified to 8x² – gx – h
Thus, by comparison of terms;
– gx = - 7x
-x will cancel out to get;
g = 7
Similarly, - h = - 3
Thus,h = 3
Therefore; g = 7 and h = 3
Answer:
0.8213
Step-by-step explanation:
-This is a binomial probability problem given by the function:

Given that n=21 and p=0.2, the probability that she experience a delay on at least 3 days is calculated as:

Hence, the probability that she experience delay on at least 3 days is 0.8213
Answer:
The questions and problem can be chosen in 1260 ways.
Step-by-step explanation:
Given that, a physics exam consists of 6 open-ended problem and 9 multiple choice questions.
The order of choosing does not matter.
So,we use combination to find ways.
The ways to choose 6 multiple choice from 9 is= 

=84
The ways to 2 open-ended question from 6 is= 

=15
Since pick 6 multiple choice out of 9 and 2 open-ended question out of 6 both are independent we have multiply both to find required ways.
Total number of ways is =(84×15)
=1260.
It's called a decimal.
I hope it helps.
