Step-by-step explanation:
3x3x9 is 36ft.
Answer:
1. T test for independent means
2. T test for dependent means
3. T test for dependent means
Step-by-step explanation:
In number 1, the two groups are unrelated. The first group has 25 subjects and they're all unemployed. The second group has 24 subjects and their employment status is not stated and might not be the same all through. Also, the first group is receiving a new type of job skills program while the second group is taking the standard job skills program.
- The groups in the experiment are unrelated
- The tests in the research are unrelated
- The purpose of the research is unreasonable - the researcher seeks to measure how well all 49 subjects perform on 'a' job skills test! No comparison between the scores or mean scores of the two groups.
In number 2, the researcher uses the same subjects and also measures the same variable but twice. This is a good example of a study where the t test for dependent means can be taken. Same applies in case 3.
Given that Nicole rented a bike from Krystal's Bikes, the number of hours is
4 hours
Given data
Initial Cost = $15
Cost per extra hours = $7
Amount Paid = $43
The Expression that we will use to describe this situation is modelled below
let y = Amount paid
m = cost per extra hour
x = the number of hours
c = the initial cost
y = mx + c -------- Equation of line
43 = 7*x + 15
43 = 7x+15
7x = 43-15
7x = 28
divide both sides by 7
x= 28/7
x= 4 hours
Hence the number of hours is 4 hours

Hi I’m someone new here and I really don’t know the answer but I’ll ask my 29 year old smart sister :)
