One customer is chosen at random for a prize giveaway. (Round answers to 4 decimal places.)
a. What is the probability that the customer is at least 20 but no older than 59?
b. What is the probability that the customer is either older than 60 or younger than 40?
c. What is the probability that the customer is at least 60?
Using it's concept, it is found that the probabilities are as follows:
a) 0.6637.
b) 0.6947.
c) 0.1527.
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
In this problem, there is a total of 83 + 63 + 99 + 65 + 73 + 69 = 452 customers.
Item a:
63 + 99 + 65 + 73 = 300 are at least 20 but no older than 59, hence:
p = 300/452 = 0.6637.
Item b:
83 + 63 + 99 = 245 are younger than 40.
69 are older than 60.
Hence:
p = (245 + 69)/452 = 0.6947.
Item c:
69 customers are at least 60, hence:
p = 69/452 = 0.1527.

Sandy bought a pair of shoes on sale for 40% off the original price and an additional 25% off the discounted price. If the shoes originally cost $60, what was the final cost, without tax, that Sandy paid for the shoes? (I ALREADY KNOW THE ANSWER. BUT I NEED THE WORK FOR THE ANSWER TO SHOW MY TEACHER) (the answer is $27)
The price is $27.00
Step-by-step explanation:
First you find 40% of 60 which is 24.
Next you subtract 24 from 60 (60-24) which equals 36.
Then you find 25% of the discounted price (36) which is 9.
Finally you subtract 9 from 36 (36-9) which is 27.
Conclusion:
So therefore the answer is $27.00.

What's the ratio for tan B
Answer:
C. [tex]tan(B) =2[/tex]
Step-by-step explanation:
Here we can see tan(B) has a opposite side of 2 and adjacent of 1.
[tex]tan(B) = \frac{opposite}{adjacent}[/tex]
[tex]tan(B) = \frac{2}{1}[/tex]
[tex]tan(B) =2[/tex]
Answer:
[tex]\textsf{tan(B)}=2[/tex]
Step-by-step explanation:
The trig ratio for tan is tan(x) = O/A
where x is the angle,
O = side OPPOSITE to the angle, and
A = side ADJACENT to the angle
For angle B:
O = 2
A = 1
Therefore, [tex]\textsf{tan(B)}=\frac{2}{1}=2[/tex]
A store pays $5 for a computer mouse and marks the price up by 45% what is the amount of the mark-up
Answer:
Mark-up = $2.25
Total price after mark-up = $7.25
Step-by-step explanation:
Well, 45% of $5 is $2.25, so now you just add that back to the total, which would be $7.25.
jayden and chandra are cleaning the house. it has 12 rooms, and each room is about the same size. when jayden cleans by himself, it takes him 6 hours. when chandra cleans by herself, it takes her 12 hours. when they clean the house together, they finish in 4 hours. when they work together, how many rooms does jayden clean and how many does chandra clean?
Jayden's work rate is twice Chandra's work rate, and, the rooms cleaned
by Jayden is twice the number of rooms cleaned by Chandra.
Response:
Jayden cleans 8 rooms while Chandra cleans 4 roomsWhich method can be used to find the number of rooms cleaned by Jayden and Chandra?Number of rooms in the house = 12
The time that Jayden takes to clean the house = 6 hours
Time that it takes Chandra to clean the house by herself = 12 hours
Time it takes both of them to clean the house = 4 hours
Required:
The number of rooms that Jayden clean and the number of rooms that
Chandra cleans when they work together.
Solution:
Given that the time it takes Jayden to clean the house is half the time
taken by Chandra.
Therefore;
The number of rooms Jayden cleans in 4 hours is twice the number of rooms cleaned by Chandra, which gives;
Ratio of the number of rooms cleaned by Jayden to the number cleaned by Chandra is 2 : 1
Total number of rooms cleaned = 12
[tex]Number \ of \ rooms \ cleaned \ by \ Jayden = \dfrac{2}{2 + 1} \times 12 = \underline{8 \ rooms}[/tex]
The number of rooms cleaned by Chandra = 12 - 8 = 4 rooms

You are in need of a $7,500 loan, which you plan to repay over 5 years. Your credit score is currently 690. Using the rates and the online calculator below, determine how much your savings would be if your credit score were 700 instead of 690.
Answer:
$232.57
Step-by-step explanation:
1 year = 12 months
⇒ 5 years = 5 x 12 = 60 months
APR credit score of 700 or higher = 13.25%
(using the APR calculator) total payment over term of loan = $10,296.56
APR credit score of 699 or lower = 14.25%
(using the APR calculator) total payment over term of loan = $10,529.13
Savings = $10,529.13 - $10,296.56 = 232.57

Square ABCD is divided into 5 rectangles that all have the same area. FH = 20 and CK = KD. Find the length of BE.
Answer:
8cm
Step-by-step explanation:
The area of a shape is the amount of space it can occupy.
The length of BE is 8 units
The question is incomplete.
So, I will give a general solution
Assume that the length BE is 2/5 of length FH.
Then the length BE would be:
BE = 2/5 * FH
Substitute 20 for FH
BE = 2/5 * 20
Evaluate the product
BE = 8
Using the assumed value, the length of BE is 8 units

Step-by-step explanation:
Simple interest formula: SI = PRT
where P = principal amount of loan, R = annual rate of Interest in decimal format, and T = Time.
Given:
P = 9573R = 4% = 4/100 = 0.04a) when T = 2:
SI = 9573 x 0.04 x 2 = 765.84

Answer:
Jessica scored 20 points, Letitia scored 40 points, and Sally scored 48 points.
Step-by-step explanation:
Let x represent the points Jessica score then...
Letitia scored 2x points (twice as many as Jessica) and Sally scored 2x+8 (8 more than Letitia) points.
We can use this information to set up an equation:
x+2x+2x+8=108
Combine like terms
5x+8=108
Subtract 8 from both sides
5x=100
Divide both sides by 5
x=20 (Jessica)
2x=2(20)=40 (Letitia)
2x+8=2(20)+8=48 (Sally)
Jessica scored 20 points, Letitia scored 40 points, and Sally scored 48 points.
