Which value is closest to f^-1(7)?
A-5
B-3
C,3
D, 5
The closest to the inverse notation is (d) 5
How to determine the closest to the inverse notationFrom the question, we have the following parameters that can be used in our computation:
The graph of the function f(x)
The notation f'(7) implies that we determine the inverse of the function
From the graph, we have the following equation
f(5) = 7
This means that
f^-1(7) = 5
Hence, the closest is (d) 5

Answer:
(3,0) (0,9)
Step-by-step explanation:
To find the x-intercept, y must equal 0
9x+3(0)=27 substitute
9x=27 divide
x=3 (3,0)
To find the y-intercept, x must equal 0
9(0)+3y=27 substitute

In a class of 25 students, 14 have a brother and 17 have a sister. There are 5 students who do not have any siblings. What is the probability that a student who has a brother also has a sister?
Answer: 11
Students have both a brother and a sister
Step-by-step explanation:
I don't think probability should be used for this question because the answer is quite clear
So in a class of 25 students
5 students don't have a sibling
So 25-5=20
Total number of siblings=14+17=31 siblings in total
So 20 people have 31 siblings
31-20=11
So the answer should be 11
In a class of 25 students, 14 have a brother and 17 have a sister. There are 5 students who do not have any siblings. The probability that a student who has a brother also has a sister is 11/25.
How to calculate the probability of an event?Suppose that there are finite elementary events in the sample space of the considered experiment, and all are equally likely.
Then, suppose we want to find the probability of an event E.
Then, its probability is given as
[tex]P(E) = \dfrac{\text{Number of favorable cases}}{\text{Number of total cases}} = \dfrac{n(E)}{n(S)}[/tex]
where favorable cases are those elementary events that belong to E, and total cases are the size of the sample space.
In a class of 25 students, 14 have a brother and 17 have a sister. There are 5 students who do not have any siblings.
So in a class of 25 students
5 students don't have a sibling
then, 25-5=20
Total number of siblings = 14+17
= 31 siblings in total
So, 20 people have 31 siblings
= 31 - 20
= 11
So, the probability that a student who has a brother also has a sister
= 11/ 25.

Find the total amount given the original price and tip rate. Round to the nearest cent if necessary. Original price: $41.32 Tip: 15%
Answer:
$6.20
Step-by-step explanation:
We can covert 15% to a decimal by moving the decimal point two places over.
15% = 0.15
41.32 X 0.15 = 6.198
6.198 ≈ $6.20
The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Original price: $41.32
Tip: 15% = %6.189
Total amount = = Original price + Tip amount
The total amount is $47.509
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
Original price: $41.32
Tip: 15%
Now,
The amount of the tip.
= 15% of 41.32
= 15/100 x 41.32
= $6.189
The total amount.
= Original price + Tip amount
= 41.32 + 6.189
= $47.509
Thus,
Original price: $41.32
Tip: 15% = %6.189
Total amount = = Original price + Tip amount
The total amount is $47.509
