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.

I'm not sure if D is right

Rzqust [24]

Ratio and proportion

height :legnth of shadow=56:49 (man's shadow)
we assume the ratio is the same for the tower thing (obelisk)

so
56:49=x:28
conver tto fraction
56/49=x/28
times both sides by 28
1568/49=x
32=x
answer is 32ft

Chareese reflects figure RSUT over the y-axis and then rotates the reflected figure 180 about the origin, resulting in figure A.

rewona [7]

Accurate. A reflection will change the direction the vertices trace around the figure. A rotation preserves the change.<span>

Grace is an hourly employee, and the line that models her total pay in dollars

tresset_1 [31]

Answer: Hello mate!

if x is the amount of hours worked, 45 is the slope and the y intercept is 35.

A linear equation has the form of y = ax + b, where a is the slope and b is the y-intercept, then the equation that we have is:

y = 45*x + 35

this means that she wins $45 per hour, and has a plane amount of $35, indiferent of the amount of hours worked.

Then the correct answer is

C) Grace's wage is $45 an hour, and it appears that she received a signing bonus of $35.
