As you are walking down a path, you see a sign telling the path has a 2% grade (ie., a rise of 2 metres for a horizontal change

Leni [432]

Answer:

Option (A)

Step-by-step explanation:

It has been given in this question that sign telling path has a 2% grade.

2% grade means a rise of 2 meters for a horizontal change of 100 m (As given in the figure attached).

All the trigonometric ratios for the angle θ between the path and the horizontal are,

Sinθ = $\frac{\text{Opposite side}}{\text{Hypotenuse}}$

Cosθ = $\frac{\text{Adjacent side}}{\text{Hypotenuse}}$

tanθ = $\frac{\text{Opposite side}}{\text{Adjacent side}}$

Since measures of the opposite side and adjacent sides are given

Therefore, tangent ratio will be applied to get the measure of the angle,

tanθ = $\frac{2}{100}$

θ = $\text{tan}^{-1}(\frac{2}{100})$

Option (A) will be the answer.

Find the indicated probability by using the complementation rule. A percentage distribution is given below for the size of famil

arlik [135]

Answer:

The correct option is c.

Step-by-step explanation:

The percentage probability distribution is:

Size (X) Percentage

2 39.9

3 24.4

4 20.1

5 10.8

6 3.3

7 1.5

Total 100.0

Compute the probability that the size of the family is 4 or more as follows:

P (X ≥ 4) = P (X = 4) + P (X = 5) + P (X = 6) + P (X = 7)

= 0.201 + 0.108 + 0.033 + 0.015

= 0.357

Thus, the probability that the size of the family is 4 or more is 0.357.

The correct option is c.
