The mean of the data set is 22.1 , and the sample proportion of numbers less than the mean is 46.67 %
What are mean?The mean is the average value which can be calculated by dividing the sum of observations by the number of observations
Mean = Sum of observations/the number of observations
Mean of the data set is calculated by adding all numbers and dividing it with total number sample data.
Then Adding all the numbers;
25.5 + 26 +18.2 +15.3 + 28.5 + 27 + 20.7 +20.2 +26.1 +18.2 +21.4 +17.9 +24.3 +22.6+ 19.6 =331.5
Now Dividing by total,
331.5/15 =22.1
Mean =22.1
The sample proportion of numbers less than the mean will be;
= (7/15 ) 100

The probability that you win is 6%, and the two choices are dependent events option (B) is correct.
What is probability?
It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.
It is given that:
A standard deck of playing cards contains 52 total cards, 13 of which are "spades".
The probability of the first draw:
Probability = favorable outcomes/total outcomes
First draw: 1/4
For the second draw:
Second draw = 12/51
The probability that you win = (1/4)(12/51) = 3/51

cover the area with two coats of paint. If
each can of paint can cover 60 square feet,
how many cans of paint will you need?
Answer:
Step-by-step explanation: √240 = 15.49…. √50 = 7.07…
15.5 x 7.07 = 109.58 rounded to 110. Therefore the area is 110 feet so at least 2 can is needed to fill up the wall. But if the problem is being precise it’s 1 can and 5/6 of a can.
2 cans of paint will be needed to cover 110 square feet area.
What is Area of Rectangle?The area of Rectangle is length times of width.

Given (x – 7)2 = 36, select the values of x. x = 13 x = 1 x = –29 x = 42
Answer:
Unless you wrote the wrong expressions, non of your choice answers are correct!
Step-by-step explanation:
Solve for x:
2 (x - 7) = 36
Divide both sides of (x - 7)×2 = 36 by 2:
(2 (x - 7))/2 = 36/2
2/2 = 1:
x - 7 = 36/2
The gcd of 36 and 2 is 2, so 36/2 = (2×18)/(2×1) = 2/2×18 = 18:
x - 7 = 18
Add 7 to both sides:
x + (7 - 7) = 7 + 18
7 - 7 = 0:
x = 18 + 7
18 + 7 = 25:
Answer: x = 25

(b) The zeros of the function f(x) are -3, -1, -1, and 1.
(c) The y-intercept is at (0,-3).
What is the endpoint behaviors of a polynomial?
A polynomial function's final behaviour is how its graph behaves as x gets closer to positive or negative infinity. The graph's final behavior is determined by a polynomial function's degree and leading coefficient.
What are zeros of a polynomial?
The locations where a polynomial becomes zero overall are known as the zeros of the polynomial. The term "zero polynomial" refers to a polynomial with a value of zero (-1). The highest power of the variable x is referred to as a polynomial's degree. A linear polynomial is a polynomial with degree 1.
Given function is f(x) = (x+3)(x+1)^2(x-1).
If x = ∞, then f(x) = ∞. The one endpoint of the function will go positive infinity.
If x =- ∞, then f(x) = -∞. The one endpoint of the function will go negative infinity.
To find the zeros of the polynomial, equate f(x) with zero.
(x+3)(x+1)^2(x-1) = 0
Either, x + 3 =0 → x = -3
or, (x+1)^2 =0 → x = -1
or, x-1 = 0 → x = 1
The zeros of the function are -3, -1, and 1.
To find y-intercept, put x=0 in the given function:
f(0) = (0+3)(0+1)^2(0-1)
→ f(0) = -3
The y-intercept is at (0,-3).
The x-intercepts of the function are zeros of the function.

How do I figure the total of a 4:3 ratio?
Step-by-step explanation:
If you take the 4:3 aspect ratio and divide 4 by 3, the result is 1.33. Therefore, you could alternately describe the 4:3 aspect ratio as 1.33:1, meaning that for every 1.33 units in width, there is 1 unit in height. Again, the same applies for the 16:9.

The point only can be on the unit circle and on the second quadrant if:
x = -√55/8
How to get the value of the x-coordinate?
We know that we have a point of the form:
P = (x, y)
And the value of y is:
y = 3/8
Then our point is:
P = (x, 3/8)
And it is on the unit circle, then the values of x and y are solutions of:
x^2 + y^2 = 1
x^2 + (3/8)^2 = 1
x^2 = 1 - (3/8)^2 = 1 - 9/64 =
x^2 = 64/64 - 9/64
x^2 = 55/64

Ratchet Manufacturing anticipates total sales for August, September, and October of $110,000, $120,000, and $130,500 respectively. Cash sales are normally 20% of total sales and the remaining sales are on credit. All credit sales are collected in the first month after the sale. Compute the amount of accounts receivable to be reported on the company's budgeted balance sheet at the end of August.
The amount of accounts receivable to be reported on the company's budgeted balance sheet at the end of August is $22000.
What is the percentage?The percentage is a ratio that can be expressed as a fraction of 100.
Given that, the sales of the company for August, September, and October are $110000, $120000, and $130500.
The company collects 20% of total sales in cash, therefore, the cash received by the company for the august month is,
110000×20%
= 110000×20/100

e. Explain why time is not a function of height in the bouncing ball experiment.
The value of velocity is [tex]v = 7.67\frac{m}{s}[/tex].
The coefficient of restitution is the ratio of the final to initial speed between two bodies after the collision. While a value of 1 indicates a perfectly elastic collision, a value of 0 indicates a perfectly inelastic collision.
The first option is
We can find the displacement by using the area under the graph, which is equal to the displacement. The area of the triangle can be found using the formula below.
[tex]Area = \frac{1}{2} . base . length[/tex]
[tex]Area = 0.5m.50m.50. = 1250 m^{3}[/tex]

We use the conservation of energy. So, we equate the potential energy and the kinetic energy.
[tex]E_{pot} = E_{kin}\\ \\ m.g.h = \frac{1}{2}.m.v^{2}[/tex]
The mass is cancelled out in the above equation, and we re-arrange with respect to velocity.

Friday: Nabil had $80.50 on a gift card before buying four journals at a bookstore. The bookstore charges 50¢ to use the card. He had $44.00 left on the gift card after buying the journals. If each journal cost the same amount, what was the price of each journal?
Answer:
$9.00 a journal.
Step-by-step explanation:
First off, you can start by subtracting $0.50 from $80.50 because it costs $0.50 to use the card.
You’re left with a new value of $80.00. Since Nabil had $44.00 left over on his card, you can subtract $44.00 from $80.00 to figure out how much he spent.
$80.00
-$44.00
————
$36.00
Since Nabil bought four journals, and they are all equal in cost, you can divide $36.00 by 4 (36/4) and get $9.00.
