Answer:
Step-by-step explanation:
We are given the following in the question:
Flat fee = 6 dollars
Charges per hour = 10 dollars per hour
Let Steve work for h hours.
Then, we can write the total charge in the following manner:
Total charge =
Putting values, we get,
is the required equation for total charges if Steve worked for h hours.
16 or more books sold in a day will include two intervals from the given table:
a) 16 - 20 books sold.
Probability = 0.201
b) 21 - 25 books sold.
Probability = ?
Since the table gives the probability distribution, the sum of all the probabilities must be equal to 1. We are given the probabilities of 4 out 5 intervals. So in order to find the probability of the 5th interval (21-25) we can subtract the sum of probabilities of rest of the intervals from 1.
So, P(21 - 25) = 0.019
In order to find the probability of 16 or more books sold we need to sum the probabilities of both these intervals.
So, the probability of 16 or more books being sold on a given day = 0.201 + 0.019 = 0.220
Answer:
Hi there!
Your answer is:
996 students were apart of this survey!
Step-by-step explanation:
3 out of 4 students means that 75% of students prefer the assemblies be held on Friday.
If 75% = 747 students then:
/75
1% = 9.96 students
×100
100% = 996 students
I hope this makes sense!
105 Animals....You know that because when you add together the head & feet that's adding all the animals together to get the total number of animals
$9.75 because one taco is 0.75 and 13 x 0.75 is $9.75
