If Jasper installs a floor himself, it will take him 7 hours. Working with Yolanda, it will take them 3 hours.
Svetllana [295]

Answer: 5\frac{1}{4} hrs

<u>Explanation:</u>

Jasper: \frac{1}{7} per hr

Yolanda: \frac{1}{x} per hr

Together: \frac{1}{3} per hr

Jasper + Yolanda = Together

\frac{1}{7} + \frac{1}{x} = \frac{1}{3}

(21x)\frac{1}{7} + (21x)\frac{1}{x} = (21x)\frac{1}{3}

3x + 21 = 7x

        21 = 4x

        \frac{21}{4} = x

         5\frac{1}{4}

7,8,9,7,2,5,3,2, 2<br><br> Mean__<br> Median__<br> Mode__<br> Range__
serious [3.7K]

Answer:

Mean: 5

Median: 5

Mode: 2

Range: 7

Step-by-step explanation:

We find the mean by adding all the numbers together to get 45. Then we divide the 45 by the amount of numbers in the set, for this one it is 9. 45 divided by 9 equals 5.

To find the median we put the numbers in the set in order from least to greatest. Next, we find the middle number. median=5

To find the mode we find the number repeated the most. In this set the number that repeats the most is 2.

Range is found by subtracting the largest number and the smallest number. 9-2=7

yKpoI14uk [10]
Given: 
Right Rectangular Prism.
It has its length, width, and height.

SA = 2 (wl + hl + hw)

V = whl

Formula of Surface Area is different from Volume.

Surface area measures the area the whole rectangular prism surface. It computes for the area of all 6 faces that a right rectangular prism has.

Volume measures the area within the rectangular prism. It is the space that is enclosed within the rectangular prism.
