A paperweight is shaped like a triangular pyramid. The base is an equilateral triangle. Find the surface area of the paperweight

melomori [17]

Answer:

Step-by-step explanation:

We have

three triangles with the base b = 2 in. and the height h₁ = 2.2 in.

one triangle with the base b = 2 in. and the height h₂ = 1.7 in.

The formula of an area of a triangle:

$A=\dfrac{b\cdot h}{2}$

b - base

h - height

Substitute:

$A_1=\dfrac{(2)(2.2)}{2}=\dfrac{4.4}{2}=2.2\ in^2$

$A_2=\dfrac{(2)(1.7)}{2}=1.7\ in^2$

$S.A.=3A_1+A_2$

$S.A.=3(2.2)+1.7=6.6+1.7=8.3\ in^2$

Listed below are the top 10 annual salaries (in millions of dollars) of TV personalities. Find the range, variance, and stand

Black_prince [1.1K]

Answer:

Step-by-step explanation:

The data is written wrongly. The correct data is:

42, 40, 38, 31, 22, 19, 17, 16, 15.9, 15.0

Range = largest value - smallest value

Range = 42 - 15 = 27

n = 10

The mean of the set of data given is

Mean = (42 + 40 + 38 + 31 + 22 + 19 + 17 + 16 + 15.9 + 15.0)/10 = 25.59

Standard deviation = √(summation(x - mean)²/n

Variance = Summation(x - mean)²/n =

Summation(x - mean)² = (42 - 25.59)^2 + (40 - 25.59)^2 + (38 - 25.59)^2 + (31 - 25.59)^2 + (22 - 25.59)^2 + (19 - 25.59)^2 + (17 - 25.59)^2 + (16 - 25.59)^2 + (15.9 - 25.59)^2 + (15.0 - 25.59)^2 = 1088.329

Variance = 1088.329/10 = 108.8329

Standard deviation = √variance = √(108.8329 = 10.43
