Which of the following is true for most distributions? Group of answer choices

Mathematics
1 answer:
Drupady [299]3 years ago
8 0

Answer:

a)

Step-by-step explanation:

The standard deviation is a measure that tells us how far measures tend to be from the mean. A low standard deviation gives us values closer to  the mean than a high standard deviation. Usually 68% of the data falls within one standard deviation of the set.

Thus, the most accurate answer would be a) Around 70% of the scores will be located within one standard deviation of the mean

A force of 50 pounds is exerted at an angle of 80 with the horizontal. What is its horizontal component?
Shalnov [3]

Answer:

Option A is the correct answer.

Explanation:

 Any vector can be resolved in to two components. Horizontal component and vertical component.

Consider a vector F which is at angle θ⁰ to the horizontal, we can resolve this vector in to two.

Horizontal component = F cos θ

Vertical component = F sin θ

Here we have Force , F = 50 pounds

Angle with horizontal = 80°

Horizontal component = F cos θ = 50* cos 80 = 8.68 pounds

                                      ≅ 9 lb.

Option A is the correct answer.
