Answer: Yes, they can.

Clarification:

We have three different sides with different lengths:

$\mathrn {14, 18, 31}$

These three lengths can form a triangle, an isosceles triangle.

Isosceles triangles have three different side lengths.

Hope this helps you. Best of Luck!

Answer:

A, or 8

Step-by-step explanation:

the total angle is 102, so we can subtract 54 from 102 to get 6x, then divide by 6.

102 -54 = 48/6 =8

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.

Two companies, A and B, package snack-size bags of cashews. Let X represent the weight of the packages from company A, and let Y

Vitek1552 [10]

The answer choice that correctly calculates and interprets the standard deviation of the sum, S = X + Y is D. Sigma Subscript s = 0.8; companies A and B can expect the total weight of packages to vary by approximately 0.8 ounces from the mean.

<h3>What does the standard deviation means?</h3>

A standard deviation means the all measure of how dispersed the data is in relation to the mean. It should be noted that low standard deviation means that the data are clustered around the mean, and the high standard deviation means that the data are more spread out.

In this case, the answer choice that correctly calculates and interprets the standard deviation of the sum, S = X + Y is the sigma Subscript s = 0.8; companies A and B can expect the total weight of packages to vary by approximately 0.8 ounces from the mean.

In conclusion, the correct option is D.

Question 5.
The function given shows represents height after a certain time. The distance measures is initial distance till the distance covered when the time is calculated. The question has given us an initial distance of 100 feet and they want us to calculate the time when the egg hits the ground, or, in other words, 0 feet. So, next, we substitute this information in the equation.
