For making a scatter plot of the data set, which would be the best scale and interval for the axis that represents the amount of
Serga [27]

I'd say the answer to the first question is D) 0 to 4 with intervals of 0.2.

Because, you can't just have 1 to 4, as some of the numbers are less than 1.  Of course you can't have 2 to 5 either. And intervals of 2 would be too messy.

For the second question:

I believe the answer is A. Because it's obvious that there IS one outlier, and it looks like there are two clusters.

So, the answers are: A) and D).

A population has a mean µ = 6 and ∑x = 48. How many scores are in the population?
maks197457 [2]

Answer:

8

Step-by-step explanation:

Recall the formula for the population mean of a data set:

\mu=\frac{\sum x}{N}

We already know that μ is 6 and the sum is 48. Substitute:

6=\frac{48}{N}

Divide both sides by 48:

\frac{1}{8}=\frac{1}{N}

Reciprocal of both sides:

N=8

Thus, there are 8 scores in the population size.

And we're done!

If the angles of a quadrilateral measure 67 degrees 123 degrees and 58 degrees what is the measure of the other angle
Cloud [144]
The other angle measures 112°.
All the angles in any 4-sided polygon will add up to 360°, like how all angles in a triangle add up to 180°. A good way to remember this is with the sum of interior angles formula:
180 x (n - 2), where n is the number of sides.

Hope that helps! if you liked this answer please rate it as brainliest so i can gain the next rank!! thank you!!!!
