Which of the following methods would result in a simple random sample of size 10 from a population consisting of 100 individuals? (Assume that a list with the names of the 100 individuals is available.) Select all that apply.
Write the 100 names on slips of paper, mix well, and then draw 10.
Number the names on the list from 0 to 99. Use a random number table to select a
digit from 0 to 9. Use this digit to select one of the first 10 people on the list and then
take every 10th person on the list thereafter.
Number the names on the list from 1 to 100 and then use random numbers to select
10 individuals from the list.
Number the names on the list from 1 to 100. Write the numbers from 1 to 100 on
slips of paper, mix well, and then select 10 of the slips. Use these numbers to select
10 individuals from the list.

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5

step-by-step explanation:

what grade level is this? need to know so i can look in my old textbooks!

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4
