What are all the factos of 36 ​
oksano4ka [1.4K]

Hi there!  

»»————- ★ ————-««

I believe your answer is:  

{1, 2, 3, 4, 6, 9, 12, 18, 36}

»»————- ★ ————-««  

Here’s why:

A factor is a whole number that is multiplied by another to have a product have another number.

⸻⸻⸻⸻

The Factors Are:

  • 1 (1 * 36 = 36)
  • 2 (2 * 18 = 36)
  • 3 (3 * 12 = 36)
  • 4 (4 * 9 = 36)
  • 6 (6 * 6 = 36)
  • 9 (9 * 4 = 36)
  • 12 (12 * 3 = 36)
  • 18 (18 * 2 = 36)
  • 36 (36 * 1 = 36)

⸻⸻⸻⸻

Hope this helps you. I apologize if it’s incorrect.

The heights of adult males in the United States are approximately normally distributed. The mean height is 70 inches (5 feet 10
steposvetlana [31]

Using the normal distribution, it is found that the probability is 0.16.

<h3>Normal Probability Distribution</h3>

In a normal distribution with mean \mu and standard deviation \sigma, the z-score of a measure X is given by:

Z = \frac{X - \mu}{\sigma}

  • It measures how many standard deviations the measure is from the mean.
  • After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.

In this problem, the mean and the standard deviation are given by, respectively, \mu = 70, \sigma = 3.

The proportion of students between 45 and 67 inches is the p-value of Z when <u>X = 67 subtracted by the p-value of Z when X = 45</u>, hence:

X = 67:

Z = \frac{X - \mu}{\sigma}

Z = \frac{67 - 70}{3}

Z = -1

Z = -1 has a p-value of 0.16.

X = 45:

Z = \frac{X - \mu}{\sigma}

Z = \frac{45 - 70}{3}

Z = -8.3

Z = -8.3 has a p-value of 0.

0.16 - 0 = 0.16

The probability is 0.16.

A tornado traveled 260 miles in 4 hours. if the average rate at which the tornado is moving slows by 20%, how many miles will th
lianna [129]
Given that the tornado traveled 260 miles in 4 hours, its initial speed is 65 mi/h. Then, slowing by 20% every hour, the speed after 2 hours can be calculated through the equation,
                          speed = (65 mi/h) x (1-0.2)^2
                             speed = 41.6 mi/h
Thus, the speed of the tornado after 2 hours is approximately 41.6 mi/h.
