SHOW ALL WORK!
Answers
6n - 3(2n-5)
mutiply the bracket by -3
(-3)(2n)= -6n
(-3)(-5)= 15
6n-6n+15
0+15
answer:
15
6n-(6n-15)
6n-6n+15
(6n-6n)+15
=15

Final answer:
The distribution is skewed.
Explanation:
The question asks about the description of the distribution of a dataset. To determine how the data is distributed, we need to analyze the shape of the graph or histogram representing the data.
If the dataset is skewed, it means that the data is not evenly distributed and there is a tail on one side. So, option A is correct. If the dataset had a bell-shaped graph with a single peak, it would be symmetric, but since it is bimodal, with two distinct peaks, option D is not accurate. The options B and C are not applicable based on the given information.
Therefore, the best description for the distribution is skewed.

Answer:
-10a² + 5a
Step-by-step explanation:
Given the expression (–5a)(2a – 1)
Open the bracket
(–5a)(2a – 1)
= -5a(2a) -5a(-1)
= -10a² + 5a
hence the equivalent expression is -10a² + 5a

Answer:
2/6 or 1/3 I think
Step-by-step explanation:
you have a 1 out of 2 chances to land tails and 1 out of 4 chance to role a 2 on the spinner. so in total there is 6 chances for rolling and flipping the coin. and there is only 1 chance for both in the odds.
therefore I believe that its is 1/3 or 2/6. I do not know if I am right exactly but that is my thought process.
