B) I say this bcz I divided 30 by 24 and got 1.25
Profit=1.25(subscription)
(If someone else proves this wrong then I am sorry but I am in Middle School and my teacher just taught me this and I got an 100 so if it doesn't help I'm sorry) (I even used all those math calculator and word problem websites)
Answer:
The correct answer is "(18, 30) minutes".
Step-by-step explanation:
Mean,
= 24
Standard deviation,
= 2
The range of minutes where 99.7% of individuals completed the quiz will be:
= 
On substituting the values, we get
= 
= 
now,
= 
= 
Or,
= 
= 
i.e., 18 to 30 minutes
She is correct.
She starts with 50
Each square foot adds 3 dollars...
so Square feet can be represented by x, and cost will be y... giving this linear function:
y=3x+50.
Answer: 0.74
Step-by-step explanation:
Given : The probability that the passengers booked for a certain flight actually show up : p=0.80
The number of passengers are randomly selected : n= 9
Binomial probability formula to find the probability of getting success in x trial :-

Then , the probability that more than 6 of them show up will be :-

Hence, the probability that more than 6 of them show up = 0.74
