Answer:
2.4
Step-by-step explanation:
First we need to find the mean
Add up all the number
(10+ 7+ 1+ 6+ 7+ 9+ 8+ 10+ 2+ 5)/10
65/10 = 6.5
Then find the absolute difference from each point and the mean and sum them together and divide by the number of points
((10-6.5) + (7-6.5) +(6.5- 1) +(6.5-6) + (7-6.5)+( 9-6.5)+( 8-6.5)+ (10-6.5)+(6.5- 2)+(6.5- 5)) /10
24/10
2.4
Answer:
a = -3/2
Step-by-step explanation:
You can set x=0 and solve for y to find the y-intercept in each case.
first equation: y-intercept = -3/2
second equation: y-intercept = a
To make these equal, we must have ...
a = -3/2
Answer:
Convenience sampling.
Step-by-step explanation:
In Statistics, sampling can be defined as a process used to collect or select data (objects, observations, or individuals) from a larger statistical population using specific procedures.
There are various types of sampling used by researchers and these are;
1. Random sampling.
2. Systematic sampling.
3. Stratified sampling.
4. Cluster sampling.
5. Quota sampling.
6. Convenience (opportunity) sampling.
Convenience sample can be defined as a sampling technique in which the representatives to be used are easily accessible. For example, a researcher using a social media poll such as Twitter polls.
In this scenario, Catherine Chao, Director of Marketing Research, chooses thirty-six of her closest friends to participate in the testing of a new toothpaste package. Thus, Catherine's sample is a convenience sampling.
I think the answer is 30....Not sure
Percentage of increase = 300%
Initial amount = $25
So amount of increase = (300/100) * 25
= 3 * 25
= 75 dollars
Then the final amount = (25 + 75) dollars
= 100 dollars
I hope this is the answer you
were looking for. The procedure should also be absolutely clear to you. It is
always possible to solve similar problems using this easy procedure. In future I
hope you will not require help from anyone for solving such problems.
