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.

What are three ratios equvilent to 8:20
Genrish500 [490]

Answer:

see explanation

Step-by-step explanation:

Multiplying or dividing each part of the ratio gives an equivalent ratio

Given

8 : 20 ← divide both parts by 2

= 4 : 10 ← divide both parts by 2

= 2 : 5 ← ratio in simplest form

Multiply both parts by 2

8 : 20 = 16 : 40

4 : 10, 2 : 5, 16: 40 ← are possible equivalent ratios

If 2a-b:2a+b=1:2find the value of a:b​
weqwewe [10]

Answer & Step-by-step explanation:

2a - b : 2a + b = 1 : 2

2a - b = 1

-                         Elimination

2a + b = 2

-b - (b) = -1

-2b = -1

b = 0.5

---------------------------------------------------------------------------------

2a + b = 2           Substitution

2a + 0.5 = 2

2a = 1.5

a = 0.75

--------------------------------------------------------------------------------------

a:b

0.75 : 0.5

or

3/4 : 1/2

Hope this helps!!!
