Step One: Place them in order from least to greatest

18 22 23 27 29 34 35

Step Two: Add them all up

18 + 22 + 23 + 27 + 29 + 34 + 35 = 188

Step Three: Divide them by the # of numbers you have.

1. 18
2. 22
3. 23
4. 27
5. 29
6. 34
7. 35

You have 7 numbers so divide the 188 (The sum) by 7.

188 ÷ 7 = 26.85

Step Four: Know what your answer is-> 26.85

A mouse climbs up a well of 86 meters. It advances 14 meters during the night, but during the day it retreats 2. The mouse will
Deffense [45]

Step-by-step explanation:

we assume day and night are equally long.

and the mouse will start at night of day 1.

then, on day 2, it will first retreat 2 meters (during daylight) and then advance 14 meters (at night).

so, on every full day, the mouse will effectively advance 12 meters (-2 + 14 = 12).

with a starting value of 14 (the first night).

so, we are getting an arithmetic sequence

an = an-1 + c

c = 12 in our case.

a1 = 14

a2 = a1 + 12 = 14+12 = 26

a3 = a2 + 12 = a1 + 12 + 12 = 14 + 2×12 = 38

an = a1 + (n-1)×12 = 14 + 12(n-1)

at what n will it reach 86 ?

86 = 14 + 12(n-1) = 14 + 12n - 12 = 2 + 12n

84 = 12n

n = 7

so, on the 7th day the mouse will reach the surface (if we truly count the first starting night day 1 - this is up to your teacher, but I would).

In each of the following situations, the sampling frame does not match the population, resulting in undercoverage. Give examples
Scrat [10]

The possible answer to your question is , under coverage in a random sampling where the result that you get is still just a partial of the whole but it could be done in anytime as long as the number of people are still there. It means that the sampling result do not just base in one session of sampling.
