You have 10 blue marbles, 8 red marbles, and 6 white marbles in a bag. You pick a red marble and put it back, pick a blue marble and put it back, and then pick a red or white marble.
Answers
Answer: depends on which probability you want (tell me and I’ll edit)
Step-by-step explanation:
10 blue
8 red
6 white
24 total
Pick a red marble: 8/24 or 1/3
Pick a blue marble: 10/24 or 5/12
Pick red or white: 14/24 or 7/12
do you want to know the probability of doing all that (pick red, put back, pick blue, put back, then pick red or white)? Or just the probability of each outcome?

Add 4 to both sides of the equation.
5x = 20
Divide both sides by 5.
x = 4
Answer:
x=4
Step-by-step explanation:
You first add 4 to both sides and get 5x=20. Then you divide both sides by 5 to isolate the x and get x=4.

On his way to a job site, Spencer stops to buy bags of concrete mix. Each bag weighs 60 pounds. Spencer’s truck can carry at most 1,700 pounds, and he already has 320 pounds of tools and other equipment in his truck. What are the possible numbers of bags of concrete mix Spencer can buy?
Answers
Answer:
28 bags but see below
Step-by-step explanation:
Start by subtracting 320 from 1700
1700 - 320 = 1680
Now he can buy any number of bags as long as he doesn't go over 1680 pounds. Let's see what that means
1680 / 60 = 28 bags of cement.
The answer to the math problem is 28 bags.
In real life, you likely want to trim it that close. What if you hit a bump. That would be very hard on the springs. I'd drop it down to 26 bags if I was actually transporting concreate mix.
He could by any number of bags between 1 and 28 in a math class and a few less in actual practice.

1. If A is an invertible matrix, then what is det(A-1) equal to?
a) 0
b) det (A)
c) 1/det(A)
d) 1
Answers
Answer:
b) det (A)
Step-by-step explanation:
The determinant of the inverse of an invertible matrix is the inverse of the determinant: det(A-1) = 1 / det(A) [6.2. 6, page 265]. Similar matrices have the same determinant; that is, if S is invertible and of the same size as A then det(S A S-1) = det(A).

Answers
Answer:
23% of people who prefer plan I are from the 36–45 age group, and 42% of people from the 46–55 age group prefer plan II.
Step-by-step explanation:
___________Plan I___ Plan II ___Neither
Ages 26–35__ 19_____ 14_______ 17
Ages 36–45__ 14 _____28_______ 8
Ages 46–55__ 27 _____21_______ 2
Total Number who prefer plan 1 = (19 + 14 + 27) = 60
Number in the 36 - 45 age group = 14
Percentage = 14 / 60 = 0.2333 = 23%
Number of people in the 46-55 age group = (27 + 21 + 2) = 50
Number on the age group who prefer plan II = 21
Percentage = 21 / 50 = 0.42 = 0.42 * 100 = 42%

Formula for volume of a cylinder = [tex]V=\pi r^2h[/tex]
Where r = radius and h = height
The cylinder shown has a given diameter of 22ft and a given height of 10ft
In order to use the formula we must convert the diameter to radius.
To do this we divide the diameter by 2 ( this is because the radius is equal to half the diameter )
so radius = 22/2 = 11
Now we plug in the dimensions into the formula
[tex]V=\pi 11^210\\11^2=121\\121*10=1210\\1210\pi[/tex]
Remember, it says " Leave your answer in terms of pi," therefore we do not apply pi and leave it as 1210π
We can conclude that the answer is A
