alex41 [277]

Answer:

The value is a statistic because the 6,076 adults in public restrooms are a sample

Step-by-step explanation:

A measure that is calculated from a sample is known as sample statistic.

A study conducted and for the study 6076 adults are selected to inquire about the hand washing habit of adults. The selected 6076 adults are a sample and for this sample we computed the average 23% which demonstrates that 23% of adults did not wash their hands before exiting. So, a statistic is 23% and  6076 adults are a sample.

The vertex angle of an isoceles triangle is 8 times the measure of the base angle. find the measure of the base angle
Yuki888 [10]
For this problem, if we used b to represent your base angle measurement, you would add 8b+2b and set it equal to 180. This is because the measure of the vertex angle is 8 times the base angle measurement, so we had to multiply b by 8. We also had to add it to the other angle measures, so the other angle measures are represented as 2b since they are the same length. We then have to set this equal to 180 since that measures of a triangle must add up to 180. Then we combine like terms on our “b” side to get 10b=180. Then we divide both sides by 10 and we get b=18, which is the measure of our base angle.
