My best guess would be A=8(7+x)
That is a correct way to figure it out I’m just not sure if it’s the correct format. :)
Answer:
40 and 16
Step-by-step explanation:
Let's say these numbers are 5x and 2x.
Their sum is 56, so
5x + 2x = 56
7x = 56
x = 8
Now substitute the unknown value with 8.
5 · 8 = <u>40</u>,
2 · 8 = <u>16</u>
Answer:
C. The height of each bar represents the category's frequency or relative frequency
Step-by-step explanation:
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.
Answer:
{-4,3,5,8}
Step-by-step explanation:
The function is in (a,b) form. Always remember that range comes after domain. So here a represents the domain and b represents the range.
In the given function:
{(-1,5),(2,8),(5,3),(13,-4)}
The range will be {5,8,3,-4}
We will write it in ascending order
{-4,3,5,8} ....
