Please help Harold took five different samples of thirty-five randomly selected students from the 520 students he surveyed. The means of the samples are shown below.

Sample

Mean

Sample 1

3.4

Sample 2

3.2

Sample 3

4.1

Sample 4

4.6

Sample 5

3.1

The predicted mean of the population will fall between

3.1 and .

1.5

3.4

3.7

4.6

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.

ask the math teacher she or he would know lol.

step-by-step explanation:

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft
