Answer:
JK+KL=JL
Step-by-step explanation:
- (x-6) +(2x-8) =16
- x-6+2x-8=16
- x+2x=16+6+8
- 3x=30
- x=30/3
- x=10
- Now KL
- 2x-8
- 2x10-8
- 20-8
- =1<u>2</u><u>(</u><u>A</u><u>)</u><u> </u>
Answer:
-24
Step-by-step explanation:
You are just counting by two's.
We call two numbers a and b, notice a>b
<span>The sum of two numbers is 110: a+b=110
</span><span>The larger number is 2 less than 7 times the smaller: a=7b-2
And by replacing a=7b-2 we have an equation: 7b-2+b=110
or 8b=110+2, and 8b=112, that means b=112:8= 14
We have two numbers: 14 and 96</span>
The stem and leaf plot will look like:
6 | 1 5 8 - 3 scores
7 | 1 7 7 9 - 4 scores
8 | 2 3 4 5 7 9 - 6 scores
9 | 0 1 4 7 9 - 1 score
To total up the number of students who scored less than 90, we have 3 under 60-69, 4 under 70-79, and 6 under 80-89, so this is 3 + 4 + 6. This is the third choice.
The list is known as the sampling frame.
To conduct a survey on current social work majors, a researcher gets a list of all students who have declared a social work major from the registrar from which a sample will be drawn.
This list is known as a sampling frame.
The sampling frame is the list from which units are drawn for the sample.
Hence, the list is known as the sampling frame.
