OlgaM077 [116]

Answer:

48% of people do NOT like walking

Step-by-step explanation:

First, write it as a fraction 13/25 (People who like jogging)

We want to find out the number of people who DON'T like walking, so we subtract 25-13=12. Put 12/25.

Lastly, convert into a percentage. Percent is out of 100, so we need to make the fraction out of 100. To do this multiply the numerator and the denominator by 4. 48/100.

=

48%

Hope this helps,

A manufacturer knows that their items have a normally distributed length, with a mean of 16.2 inches, and standard deviation of
statuscvo [17]

Answer:

57.926%

Step-by-step explanation:

Calculation for the probability that it is less than

16.4 inches long

Using this formula

z = (X - μ) / σ

Where,

X represent Date=16.4

μ represent Mean=16.2

σ represent Standard deviation=0.9 inches

Let plug in the formula

z = (16.4 - 16.2) /0.9 inches

z=0.2/0.9 inches

z = 0.2

Using Z-score table to find the area of 0.2

z=0.57926*100

z=57.926%

Therefore the probability that it is less than

16.4 inches long is 57.926%

valina [46]

Answer:

a is adjacent, b is opposite, c is the hypotenuse

Step-by-step explanation:

see the attached figure to better understand the problem

In the right triangle XYZ we have

The side a and side b are the legs and the side c is the hypotenuse (the greater side)

The side a is the adjacent side to angle Y and is the opposite side to angle X

The side b is the opposite side to angle Y and is the adjacent side to angle X

The side c is the hypotenuse

The sum of the angles X and Y is equal to 90 degrees because are  complementary angles

therefore

a is adjacent, b is opposite, c is the hypotenuse
