Answer:

Step-by-step explanation:

To get the y-intercept, we need to get the slope first

Slope = y2-y1/x2-x1

Slope = -20-1/-3-4

slope = -21/-7

Slope = 3

Get the y-intercept. Substitute m = 3 and any point say (4, 1) into the expression y = mx+c

c is the y-intercept

1 = 3(4) + c

1 = 12 + c

c =1-12

c = -11

Hence the y-intercept is -11

What is the Mean,Mode and range of the set below?:

Zepler [3.9K]

Answer:

Set of numbers: 5, 6, 8, 10, 11, 15, 17, 25, 29, 29, 41, 50, 51, 52, 52, 54, 56, 57, 57

Mean: 32.89

Median: 29

Mode: 29, 52, 57

Range: 52

Step-by-step explanation:

The numbers are already ordered for us, so to find the mean, we need to add the numbers and divide the sum by the number of numbers. This gives us about 32.89.

The median is the middle number in the set, so right in the middle of the set is 29.

The range is the biggest number minus the smallest number, which would be 57-5 = 52.

Mode is the value or values in the data set that occur most frequently, which would be 29, 52, and 57, because they all occur the same number of times.

Happy learning and sorry for the late answer!

A 1 = 57, a 2 = 61, a 3 = 65 ( arithmetic sequence )
a n = a 1 + ( n - 1 ) d
a 2 = a 1 + d
61 = 57 + d
d = 61 - 57
d = 4
a 9 = 57 + 8 * 4 = 57 + 36 = 93
Answer: Her score on the 9th assessment will be 93 points.

In order to estimate the mean amount of time computer users spend on the internet each month, how many computer users must be su

prisoha [69]

Answer:

1568

Step-by-step explanation:

The computation of the minimum sample size is shown below:

Given that

Error E = 11

The population standard deviation $\sigma$ =217

Confidence level 1-α = 95%

Now following formula should be used

n > (Zalpha ÷ 2 × sigma ÷ E)^2

As we know that

Zalpha ÷ 2= 1.96

Now the sample size is

n> (1.96 × 202 ÷ 10)^2

= 1568
