Answer: D. A single number calculated from the sample that estimates a target population parameter is called a point estimator.
An interval estimator is a range of numbers that contain the target parameter with a high degree of confidence.
Step-by-step explanation:
When we evaluate an range of values for an unknown population parameter, then it is known as interval estimation .
A single number evaluated from the SAMPLE that estimates an unknown population parameter is known as a point estimator.
The general difference between point and interval estimator is the point estimator is a single value of target parameter while interval estimator is a range of numbers to estimate the values about the unknown population.
Answer:
∠6=78° ∠7=102° ∠14=78°
Step-by-step explanation:
Angles 6 and 7 are supplementary angles so ∠a+∠b=180°
in this case it would be 102°+x=180° and you subtract 102° from 180° getting 78°
∠7 is the vertical angles postulate stating that any angles vertical to each other are eaqual

Answer:
B) 4,320
Step-by-step explanation:
You would first find the volume of the triangular prism using this formula:
V = 1/2 x A x C x H
A = 3 C = 6 H = 24
V = 1/2 x 3 x 6 x 24 = 216 cubic feet
Since there are 20 pounds of snow per cubic foot, you multiply the cubic feet (216) by the pounds of snow per cubic foot (20):
216 x 20 = 4,320 pounds
