Answer:

Step-by-step explanation:

The number of defective laptops = 6/145 * 100 as a percent.

The number of defective laptops = 4.13% in a sample of 145

A: False. The percentage should be the same for 290 laptops. The % does not change. The number of defective laptops will change (12)

B: True. It is a reason assertion that about 4% of all laptops will be defective.

C: True. It is not reasonable to assume that only 0.5 laptops will be defective. .5% is too small.

D: True. 10% is too high.

E: False. The variation should not be much.

The answer is B

sin=Opposite/Hypotenuse

sin=28/100

Divide numerator and denominator by 4

sin=7/25

Cosine=adjacent/hypotenuse

cos=96/100

Divide numerator and denominator by 4

cos=24/25

Tangent=opposite/adjacent

tan=28/96

Divide numerator and denominator by 4

tan=7/24

A is the correct answer. Both diagonals would be the same length as it is a rectangle and when you substitute 7 for X in the equations, the answer is 26 for both.
