Ski resorts are interested in the mean age that children take their first ski and snowboard lessons. They need this information to plan their ski classes optimally. Define the following in terms of the study. Give examples where appropriate. The sample:

a. The sample is all of the people taking skiing or snowboarding lessons.
b. The sample is all of the children taking skiing or snowboarding lessons.
c. The sample is a group of the people taking skiing or snowboarding lessons.
d. The sample is a group of the children taking skiing or snowboarding lessons.

Option D

Step-by-step explanation:

A sample can be described as a small part or potion that is intended to describe what the whole population is like.

In this study, the sample is a group of the children taking skiing or snowboarding lessons: this group is taken out of the whole population of children taking skiing or snowboarding lessons.

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value

step-by-step explanation:

a cube has 6 sides

the probability of getting 5 on the first cube is 1/6 since only one side of the cube has 5 on it.

there are 3 sides of the cube with even number on it [2,4,6]

therefore the probability of getting even number is 3/6

for both events to happen together, the probability would be

1/6 x 3/6 = 12/36

which simplifies to 1/12
