Answer:

26 and 43

Step-by-step explanation:

The difference between the two numbers is 17, so we can set the two numbers as x and x+17. We also know that the sum of the two numbers are 69, so we can set up the equation x+(x+17)=69.

x+(x+17)=69

2x+17=69

2x=52

x=26.

If x=26, then the other number would be x+17, which is 43, so the two numbers are 26 and 43.

Solution:

Note that:

AB = EF
BC = EG = 6x - 8
7x - 19 = 2x + 11
Perimeter of triangle: 24 + 2x + 11 + 6x - 8

Solving for x:

7x - 19 = 2x + 11
=> 7x - 2x = 19 + 11
=> 5x = 30
=> x = 30/5 = 6

Substitute the value of x into the expression (24 + 2x + 11 + 6x - 8):

24 + 2x + 11 + 6x - 8
=> 24 + 2(6) + 11 + 6(6) - 8
=> 24 + 12 + 11 + 36 - 8
=> 24 + 12 + 3 + 36
=> 75 units

The perimeter of the triangle ABC is 75 units.

Using the normal distribution and the central limit theorem, it is found that there is a 0.0166 = 1.66% probability of a sample proportion of 0.59 or less.

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.

By the Central Limit Theorem, the sampling distribution of sampling proportions of a proportion p in a sample of size n has mean $\mu = p$ and standard error $s = \sqrt{\frac{p(1 - p)}{n}}$
