Hey PLZZZZ HELP!
The profits earned in a year by some companies in a city are shown below: Company Profit A $160,000 B $140,000 C $130,000 D $1,120,000 E $150,000 Based on the data, should the mean or the median be used to make an inference about the profits earned by these companies? Mean, because it is in the center of the data Median, because it is in the center of the data Mean, because there are no outliers that affect the mean Median, because there is an outlier that affects the mean
Answer:
mean because there is an outlier
Step-by-step explanation:
since there is an outlier that affected the mean which is company D, it can only be mean because the outlier is too big.

Consider the 720 permutations of the numbers 1, 2, 3, 4, 5, 6. In how many of these permutations do exactly 3 of the numbers end up in the positions where they started?
The set {1,2,3,4,5,6} has a total of 6! permutations
a. Of those 6! permutations, 5!=120 begin with 1. So first 120 numbers would contain 1 as the unit digit.
b. The next 120, including the 124th, would begin with 2.
c. Then of the 5! numbers beginning with 2, there are 4!=24 including the 124th number, which have the second digit =1
d. Of these 4! permutations beginning with 21, there are 3!=6 including the 124th permutation which have third digit 3
e. Among these 3! permutations beginning with 213, there are 2 numbers with the fourth digit =4 (121th & 122th), 2 with fourth digit 5 (numbers 123 & 124) and 2 with fourth digit 6 (numbers 125 and 126).
Lastly, of the 2! permutations beginning with 2135, there is one with 5th digit 4 (number 123) and one with 5 digit 6 (number 124).
∴ The 124th number is 213564
Similarly reversing the above procedure we can determine the position of 321546 to be 267th on the list.
helpppp plzzz...plz give steps
Answer:
Volume of hemisphere =
[tex] \frac{2}{3} \pi \: r {}^{3} [/tex]
Given volume =
[tex]18\pi \: cube[/tex]
[tex] \frac{2}{3} \times \frac{22}{7} \: {r}^{3} = 18 \times \frac{22}{7} [/tex]
So pi is there on both the sides so it will be cut from both LHS and RHS
[tex] \frac{2}{3} \times r {}^{3} = 18[/tex]
[tex]2 \times r {}^{3 } = 18 \times 3[/tex]
[tex]2 \times r {}^{3} = 54[/tex]
[tex]r {}^{3} = \frac{54}{2} [/tex]
[tex]r {}^{3} = 27[/tex]
[tex]r = 3[/tex]
Therefore value of r=3 inches

Answer:
83
Step-by-step explanation:
its a guess bc its a right triangle and right triangle is 90 degrees minus 7 is 83
Answer:
I think it is 93 degrees
Step-by-step explanation:
A triangle has a full angle of 180 degrees
47+47 = 94
180-94=86
x-7=86
x = 93

Solve the following equation.
U + 2 = 4
Answer:
U=2
Step-by-step explanation:
This is a simple one-step algebraic equation. In algebra to solve equations, you should use the properties of equality. The properties say that an equation remains true as long as the same thing happens on both sides. For this equation, the property of subtracting should be used; this property states that the same number can be subtracted from both sides. To find U, isolate the variable by subtracting 2 from both sides. This leaves U=2.

Answer:
AC=2.868
Step-by-step explanation:
using pythagoras theorem
take 35 degree as reference angle
hypotenuse =5 , opposite =AC , adjacent=BC
using sin rule
sin 35=opposite/hypotenuse
0.5735=AC/5
0.5735*5=AC
2.8675=AC
2.868=AC
find surface area of the square pyramid!!! pls i need help with explaining!!!!!
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:
How do I solve this?
Answer:
We know the width maybe 22ft and at its widest.
IF we say 3 triangles can be fit into a polygon given 2 sides then we 180 x 3 = 560 degree if its 3 rectangles then if it is easier to make 4 rectangles if square shape we can subtract the smaller measures of the missing rectangle.
With triangles;
The number of triangles is always 2 less than that that of its sides.
= 3 triangles + 2 = 5 sides.
The sum of interior angles
(n-2) x 180 = 540 degree
5-2 x 180
To determine the amount of sides; we remember
(n-2) 180
360 = (n-2) 180
+360 = 180 -360 +180
+360 = 180 = (3 triangles with 180)
900/180 = 5 sides.
If we say 5 triangles created with 3 given lengths
then same rule applies n-2 (180)
=7 sides

A square pyramid. The square base has side lengths of 5 feet. The 4 triangular sides have a base of 5 feet and height of 6 feet.
What is the surface area of a pyramid with a base area of 25 ft2 and lateral faces each with areas of 15 ft2?
Answer:
85 ft^2
Step-by-step explanation:
Ok, the square base area is 5 x 5 = 25 square feet
the triangular sides have an area of (1/2)(5)(6) each, which is 15 square feet each, like you said.
To find the total surface area, you multiply the 15 square feet x 4 (there are 4 sides) and add the base.
15 x 4 = 60 + 25 = 85 square feet
