Find the mean, median, and mode of the data set. Round to the nearest tenth.
5, 7, 2, 6, 7, 10, 12, 7, 9, 13, 5
Answers
Answer:
The mean is 7.5.
The median is 7.
The mode is 7.
Step-by-step explanation:
To find the mean, add up all the numbers in the data set and then divide the sum by the total number of values.
5 + 7 + 2 + 6 + 7 + 10 + 12 + 7 + 9 + 13 + 5 = 83
83 divided 11 equals 7.5.
To find the median, arrange all the numbers in the data set from smallest to largest and then find the number that is in the middle of the set.
To find the mode, put the numbers in order from least to greatest and count how many times each number occurs. The number that occurs the most is the mode.

find surface area of the square pyramid!!! pls i need help with explaining!!!!!
Answers
Answer:
39 square yards
Step-by-step explanation:
The base is a square, so the area is 3 x 3 = 9.
Each side is a triangle, and the formula for that is (1/2)(base)(height)
The base of each side is 3 and the height of each is 5. There are 4 of those, so it's 4 x (1/2)(3)(5) = (2)(3)(5) = 30
Add the base and sides
30 + 9 = 39
Answer:
39 yards
Step-by-step explanation:
surface area = A + [tex]\frac{1}{2}[/tex] ps
A = area of the base
p = perimeter of the base
s = slant height
the base of the pyramid is a square, all sides and angles are equal
; 3 yards
; area of a square = l x w
; area of the base = 9 yd (A)
perimeter of the base ; 3 + 3 + 3 + 3 = 12 yd (p)
slant height = 5 yd (s)
; sub it into the formula
surface area = 9 + [tex]\frac{1}{2}[/tex] x 12 x 5
surface area = 39 yd

Step-by-step explanation:
Using the tip, (4+5=9 is equal to 5+4=9), just switch the two numbers that add up to 888. So instead of 136+752=888, do 752+136=888 because both of those add up to the same number.

Answer:

Step-by-step explanation:
Volume of a hemisphere = [tex]\frac{2}{3}[/tex]π[tex]r^{3}[/tex]
=> 18π = [tex]\frac{2}{3}[/tex]π[tex]r^{3}[/tex]
=> 18 = [tex]\frac{2}{3}[/tex][tex]r^{3}[/tex]
=> [tex]r^{3}[/tex] = 18 × [tex]\frac{3}{2}[/tex]
=> [tex]r^{3}[/tex] = 27
=> r = [tex]\sqrt[3]{27}[/tex]
=> r = 3 inches
Therefore, the radius of the hemisphere in inches is 3 inches.
