Answer:
84%
Step-by-step explanation:
To find the mean, you use a formula.
You add up all the numbers, then divide that by how many numbers you have:
80 + 92 + 80 + 84
336 / 4 = 84

What is the slope percentage of 1 12?
The slope percentage of the given ratio i.e. 1:12 is 83.33%.
You can determine the slope percentage by dividing the elevation change by the horizontal distance covered (sometimes called "the rise divided by the run") and multiplying the result by 100. The "run" assumes a flat surface - it doesn't account for elevation change when factoring in the actual distance traveled.
Example: let’s assume a mountaineer climbs 1,000 feet in altitude (the rise) and the horizontal distance measured on the map is 2,000 feet (the run).
thus, 1,000/2,000 = 0.5
Multiply 0.5 by 100 to derive the percent of the slope, which is 50%.
Hence, the slope percentage of 1:12 is = (1/12) x 100
= 8.33 x 100
= 83.33 %.

an organization wants to select a committee of 3 members from a group of 11 eligible members. how many different committees are possible?
the 165 different committees are possible in combination.
What is combination?
If the order of the selections is unimportant, a combination is a mathematical choice made from a collection of various elements (unlike permutations). An apple and a pear are just one of three conceivable combinations if three fruits, such as an orange, an apple, and a pear, are provided. A k-combination of a set S is, technically speaking, a subset of the k distinctive elements of S. Alternatively said, two combinations are identical if and only if they have the same members. (How each set's members are ordered is not crucial.) the number of k-combinations given a set of n elements
That would be equal to the Combinations of 11 items taken 3 at a time.
C(n , k) = n!/[k!(n - k)!]
= 11!/[3!*(11 - 3)!]
= 11!/(3!*8!)
= 11*10*9/3*2

The length of a rectangle is twice its width. If its perimeter is 54 cm, find its length.
a. 18 cm
b. 10 cm
c. 19 cm
d. 15 cm
The length of a rectangle is found to be 18 cm.
An enclosed 2-D shape plane called a rectangle has four sides, four corners, and four right angles (90°). It has equal and parallel opposite sides. Because a rectangle is a two-dimensional form, it has length and width as its two dimensions. The length of a rectangle is considered as its longer side; its breadth is considered as its shorter side.
The perimeter of the rectangle is given as 54 cm. Let's consider the length of the rectangle as x and the width as y.
The formula to calculate the perimeter is 2(x+y).
The length is given as 2y.
Then, the perimeter is,
[tex]\begin{aligned}\text{Perimeter}&=2(2y+y)\\&=4y+2y\\&=6y\\54&=6y\\y&=\frac{54}{6}\\&=9\end{aligned}[/tex]
Then, the length is 2y=2×9=18.

A line's steepness is determined by its slope. In mathematics, slope is determined by "rise over run" (change in y divided by change in x).
Let the given points as shown:
(x1,y1)= (-5, 6) and (x2,y2)= (-9, -6)
Slope = m = (y2-y1) /( x2-x1)

A shirt is on sale for 25% off. If the original price was $120, what is the sale price?
Answer:
If a shirt is on sale for 25% off and the original price was $120, then the sale price is $90. This is because 25% of $120 is $30, and when we subtract this amount from the original price, we get $120 - $30 = $90.
In general, if an item is on sale for x% off and the original price was y dollars, then the sale price is y - (x/100) * y dollars. For example, if the discount is 25% and the original price is $120, then the sale price would be $120 - (25/100) * $120 = $90.

Answer:
The sale price is $90
Step-by-step explanation:
Given;A shirt is on sale for 25% off. If the original price was $120.To Find;The sale price.Now,
