Answer: Simple random sampling
Step-by-step explanation:
Given: A market researcher obtains a list of all streets in a town. She randomly samples 10 street names from the list, and then administers survey questions to every family living on those 10 streets.
Since she randomly samples street names , therefore the type of sampling is simple random sampling.
- A simple random sample is a sample that is a subset of the population the researcher surveyed selected in a way such that all the individuals in the population has an equal chance to be selected.
Answer: A
Step-by-step explanation:
When you use the distributive property, you are multiplying every term in the parentheses by the number outside of it. You are typically multiplying so that is how you will get the simplified form of your equation.
Answer:
Yes
Step-by-step explanation:
91 is a multiple of 13 because it is divisible by 13.
91 divided by 13 is equal to 7.
This means 91 is a multiple of 13, because you can multiply 13 by 7 to get 91.
<u>Part 1: Finding radius</u>
The radius of a circle is defined as the distance from the center to a point on the circle's circumference.
Using the distance formula,
<u>Part 2: Finding the point with x-coordinate -15</u>
Let the y coordinate of the point be y. Then, we have the point (-15, y). Substituting into the distance formula,
<h3>
</h3>
Simplify both sides of the inequality.
Subtract 3x from both sides.
<h3>
</h3><h3>
</h3>
Subtract 6 from both sides.
