Answer:

B. $\sqrt{18}$

Step-by-step explanation:

While we don't know exactly where it is, we know that it's not A, as $\sqrt{10} < 4$ .

We know it's not D, because $\sqrt{12} < 4$

We're left with B and C. We know that $\sqrt{24} > \sqrt{20.25} = 4.5$ so it's not C either.

B is the only sensible answer.

Some emoji math, there are more to be solve as well. 15 points for each. Must explain how to get the answers you got.

Maslowich

Answer:

Ladybug=7

clock= 5

bulb= 2

Step-by-step explanation:

there are a whole row of ladybugs that equal 21. 21/3=7.

on the third row, the value we need is 12, 6 won't work because we also have a bulb. so pug in 5, 5+5=10, that means the bulb is 2.

So now that we know the values, lets plug them into the first problem to see if it gives us 14... it does

So we have the correct answers

Also, you can plug in the values for the the bottom numbers and you will get those values

A published report of a repeated-measures research study includes the following description of the statistical analysis. "The re

balandron [24]

Answer:

3 treatment conditions were compared in the study.

14 individuals participated in the study.

Step-by-step explanation:

Consider the provided information.

Part (A) How many treatment conditions were compared in the study?

There are two sets of degrees of freedom; one for the numerator and one for the denominator.

F ratio is defined as: $df=(df_{\text{Between treatment}}, df_{error})$

The formula for between treatment is: $df_{\text{Between treatment}}=k-1$

Substitute $df_{\text{Between treatment}}=2$ in above formula.

$2=k-1$

$k=3$

Therefore, 3 treatment conditions were compared in the study.

Part (B) How many individuals participated in the study?

The error degree of freedom is $df_{error}=(k-1)(n-1)$

Substitute $df_{error}=26$ and k=3 in above formula.

$26=(3-1)(n-1)$

$26=2(n-1)$

$14=n$

Hence, 14 individuals participated in the study.

3x/4=6/5 solve the equation for x

Luba_88 [7]

Answer:

x = 8/5

Step-by-step explanation:

3x/4 = 6/5

15x = 24 (Use the common denominator 20. After everything is under 20, it doesn't really matter if you have it in the equation.)

x = 24/15

x = 8/5
