A bag contains 9 red balls numbered 1, 2, 3, 4, 5, 6, 7, 8, 9 and 6 white balls numbered 10, 11, 12, 13, 14, 15. One ball is drawn from the bag. What is the probability that the ball is red, given that the ball is odd-numbered? (Enter your probability as a fraction.)
Answer: 5/8
Step-by-step explanation: There are 5 odd-numbered balls in the red numbered balls. There are 3 odd-numbered balls in the white numbered balls. So the probability of choosing a red odd numbered ball out of the set of all odd numbered balls is 5/8! Hope this helps!

(a) Laura pumped 7 gallons of water into her pool each minute for 14 minutes. What was the total change in the amount of water in the pool?
Answer:
98 gallons
Step-by-step explanation:
Laura's Pump rate = 7 gallon/minute.
Thus, the total change in 14 minutes =
7(14) = 98 gallons
I know why no ones answering your questions. Because there is not enough info.

Suppose that the members of a student governance committee will be selected from the 40 members of the student senate. There are 18 sophomores, 12 juniors and 10 seniors who are members of the student senate. In how many ways can the governance committee be selected, if it must be made up of 2 sophomores, 2 juniors and 3 seniors? Assume that each of the sophomores, each of the juniors and each of the seniors is equally likely to be selected for the committee.
Using the combination formula, it is found that the committee can be selected in 1,211,760 ways.
Combination formula:
[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by:

[tex]T = C_{18,2} \times C_{12,2} \times C_{10,3} = \frac{18!}{2!16!} \times \frac{12!}{2!10!} \times \frac{10!}{3!7!} = 1211760[/tex]

What is the area of a rectangle with a length of 5 units and a width of 8 units
Answer:
40 square units
Step-by-step explanation:
A = LW
A = 5 units x 8 units
A = 40 square units
Answer:
40^2
Step-by-step explanation:
The formula for finding the area of a triangle is length times width. So all you have to do is multiply the length 5 and width 8 together to give you 40. Therefore, the area of the rectangle is 40^2.
13. Maddie purchased a sofa and a chair for her new apartment. The sofa cost $40 more
than twice the chair. She paid a total of $1252. What did she pay for each one?
The sofa cost $848 while the chair cost $404
Let x represent the cost of the sofa and y represent the cost of the chair.
The sofa cost $40 more than twice the chair, hence:
x = 2y + 40
x - 2y = 40 (1)
She paid a total of $1252, hence:
x + y = 1252 (2)
Solving equation 1 and 2 simultaneously gives:
x = 848, y = 404
Therefore the sofa cost $848 while the chair cost $404

A field is a rectangle with a perimeter of 1200 feet. The length is 200 feet more than the width. Find the width and length of the rectangle field
Answer:
Step-by-step explanation:
let the width be w
p=l*w
1200= 200*w
1200= 200w
1200 = 200w
6 feet = w
width is 6 feet
let the length be a
p = l* w
1200 = a* 6
1200 = 6a
1200 = 6a
200 feet = a
length is 200 feet
Which equation is correct?
8 dot 8 equals 8 Superscript 2 equals 16.
9 dot 9 equals 2 left-parenthesis 9 right-parenthesis equals 18.
10 dot 10 equals 2 left-parenthesis 10 right-parenthesis equals 100.
11 dot 11 equals 11 Superscript 2 equals 121.
The equation that is correct is 11.11 = 11² = 121. The correct answer is the fourth option: 11 dot 11 equals 11 Superscript 2 equals 121 (11.11 = 11² = 121)
From the question,
We are to determine which of the options is correct.
To determine which of the options is correct, we will evaluate the options one after the other.
For the first option8 dot 8 equals 8 Superscript 2 equals 16
That is,
8.8 = 8² = 16
Evaluating properly
8.8 = 8² = 8 × 8 = 64
Then, 8.8 = 8² ≠ 16
∴ This is NOT correct
For the second option9 dot 9 equals 2 left-parenthesis 9 right-parenthesis equals 18
That is,
9.9 = 2(9) = 18
Evaluating properly
9.9 = 9 × 9 = 9² = 81
Then, 9.9 ≠ 2(9) = 18
∴ This is NOT correct
For the third option10 dot 10 equals 2 left-parenthesis 10 right-parenthesis equals 100
That is,
10.10 = 2(10) = 100
Evaluating properly
10.10 = 10 × 10 = 10² = 100
Then, 10.10 ≠ 2(10) ≠ 100
∴This is NOT correct
For the fourth option11 dot 11 equals 11 Superscript 2 equals 121
That is,
11.11 = 11² = 121
Evaluating properly
11.11 = 11² = 11 × 11 = 121
Then, 11.11 = 11² = 121
This is correct.
Hence, the equation that is correct is 11.11 = 11² = 121. The correct answer is the fourth option: 11 dot 11 equals 11 Superscript 2 equals 121 (11.11 = 11² = 121)

Given lines are parallel, find the value of x.
Then determine the measure of the angle.
Answers:
x = 45angle measure = 104 degrees============================================================
Explanation:
These angles are on alternating sides of the transversal line, and they are exterior of the parallel lines. Therefore, these are alternate exterior angles.
Alternate exterior angles are congruent when we have parallel lines like this.
Set the two expressions equal to each other. Solve for x.
3x-31 = x+59
3x-x = 59+31
2x = 90
x = 90/2
x = 45
Then we can find that:
3x-31 = 3*45-31 = 135-31 = 104x+59 = 45+59 = 104Both alternate exterior angles are 104 degrees each, which confirms we have the correct x value.

Answer:
The square root of 144 is 12

[tex]\sqrt{144} = 12[/tex]
because 12 x 12 = 144
it's basically 12 doubled... [tex]12^{2}[/tex]
Answer:
12 is the square root of 144.
Step-by-step explanation:
That means if you multiply 12 by 12, you will get 144.
That's called 12² (12 squared)
The square root is the opposite of that. √144=12.
Keep in mind that 12*12=144.

Pls mark brainliest :P
And have an amazing day <3
Answer:
A sample standard deviation is a statistic. This means that it is calculated from only some of the individuals in a population. Since the sample standard deviation depends upon the sample, it has greater variability. Thus the standard deviation of the sample is greater than that of the population.
