Answer:

20%

Step-by-step explanation:

If he rolled the dice 50 times and got the following result

Sum of the number-Number of rolls

2-1

3-4

4-3

5-6

6-7

7-10

8-7

9-5

10-4

11-2

12-1

What percentage of the rolls resulted in a sum of 7?

Percentage of the rolls that resulted in a sum of 7 = 100% × (number of times the sum of 7 showed up)/(total number of rolls)

From the data presented above,

number of times the sum of 7 showed up = 10

total number of rolls = 50

Percentage of the rolls that resulted in a sum of 7 = 100% × (10/50) = 20%

An electrician leans an extension ladder against the outside wall of a house so that it reaches an electric box 22 feet up. The
jeka57 [31]

The ladder and the outside wall form a right triangle

The length of the ladder is 97.8 feet

<h3>How to determine the length of the ladder?</h3>

The given parameters are:

Distance (B) = 22 feet

Angle of elevation (θ) = 77 degrees

The length (L) of the ladder is calculated using the following cosine ratio

cos(θ) = B/L

So, we have:

cos(77) = 22/L

Make L the subject

L = 22/cos(77)

Evaluate the product

L = 97.8

Hence, the length of the ladder is 97.8 feet
