Answer:

D. 108.25 sq in

Step-by-step explanation:

Area of triangle = bh/2

Area of bottom triangle = 4.3(5)/2 = 10.75

Area of a lateral triangle = 13(5)/2 = 32.5

Area of 3 lateral triangles = 3(32.5) = 97.5

Total surface area = 10.75 + 97.5 = 108.25

On the rectangular coordinate system, what is the shortest distance between points (−4, 3) and (−2, −1)?

pogonyaev

Shortest Distance = $\sqrt{ (-4+2)^{2} + (3+1)^{2} }$
Shortest Distance = $\sqrt{ (-2)^{2} + (4)^{2} }$
Shortest Distance = $\sqrt{20}$
Shortest Distance = $4.47 units$

Last summers, students who worked earned an average of $80 a week with a standard deviation of $12. What percentage of students

Roman55 [17]

Answer:

2.28%

Step-by-step explanation:

Given:

μ = 80
σ = 12
x = 104

Find z-score:

z = (x - μ)/σ
z = (104 - 80)/12 = 2

Percent value corresponding to 2 as per z-table is 0.9772. This is corresponding to 97.72%.

Percentage of students earned more than $104:

100 - 97.72 = 2.28
