The pairs of numbers that multiply to 20 are:
(1,20),(2,10),(5,4)

The pair that also adds up to 20 is (2,10). So these are the two numbers you need.

Three students want to estimate the mean word length of the same book. To do this, each student randomly chose 4 words from the

Firlakuza [10]

The solutions to the questions are given below

sample(n) word length sample mean

1 5,4,4,2 3.75

2 3,2,3,6 3.5

3 5,6,3,3 4.25

b)R =0.75

The mean of the sample means will tend to be a better estimate than a single sample mean.
The closer the range of the sample means is to 0, the more confident they can be in their estimate.

<h3>What is the students are going to use the sample means to estimate the mean word length in the book.?</h3>

The table below shows sample means in the table.

sample(n) word length sample mean

1 5,4,4,2 3.75

2 3,2,3,6 3.5

3 5,6,3,3 4.25

Generally, the equation for is mathematically given as

variation in the sample means

R =maximum -minimum

R=4.25-3.5

R =0.75

In conclusion, In most cases, the mean of many samples will provide a more accurate estimate than the mean of a single sample.

They may have a higher level of confidence in their estimate if the range of the sample means is closer to 0 than it is now.

What is the slope of the line that goes through (2, 5) and (-6, -2) ?

alexira [117]

Answer:
slope = 7/8

Explanation:
Slope of the line can be calculated using the following equation:
slope = $\frac{y2 - y1}{x2 - x1}$

The two points given are:
(2,5) representing (x1 , y1)
(-6,-2) representing (x2 , y2)

Substitute with the points in the above equation to get the slope as follows:
slope = $\frac{-2 - 5}{-6 - 2}$ = 7/8

Hope this helps :)
