A researcher reports an F-ratio with df between = 3 and df within = 40 from an independent-measures ANOVA. How many treatment co

nditions were compared in the experiment?

Answer:

4 treatment

Step-by-step explanation:

The degree of freedom between = number of treatment (t) - 1

Degree of freedom between = 3

Hence,

3 = t - 1

Add 1 to both sides

3 + 1 = t - 1 + 1

4 = t

4 treatments

I count 4 green stars and 6 red stars

ratio of green to red would be
4 green : 6 red

4:6

if you divide both numbers by 2, cause theyre both even

2:3

67. The line contains the point (4,0) and is parallel<br> to the line defined by 3x = 2y.

olganol [36]

Answer:

$y=\frac{3}{2} x-6$

Step-by-step explanation:

Hi there!

<u>What we need to know:</u>

Linear equations are typically organized in slope-intercept form:

$y=mx+b$ where m is the slope of the line and b is the y-intercept (the value of y when the line crosses the y-axis)

Parallel lines will always have the same slope but different y-intercepts.

<u>1) Determine the slope of the parallel line</u>

Organize 3x = 2y into slope-intercept form. Why? So we can easily identify the slope, m.

$3x = 2y$

Switch the sides

$2y=3x$

Divide both sides by 2 to isolate y

$\frac{2y}{2} = \frac{3}{2} x\\y=\frac{3}{2} x$

Now that this equation is in slope-intercept form, we can easily identify that $\frac{3}{2}$ is in the place of m. Therefore, because parallel lines have the same slope, the parallel line we're solving for now will also have the slope $\frac{3}{2}$ . Plug this into $y=mx+b$ :

$y=\frac{3}{2} x+b$

<u>2) Determine the y-intercept</u>

$y=\frac{3}{2} x+b$

Plug in the given point, (4,0)

$0=\frac{3}{2} (4)+b\\0=6+b$

Subtract both sides by 6

$0-6=6+b-6\\-6=b$

Therefore, -6 is the y-intercept of the line. Plug this into $y=\frac{3}{2} x+b$ as b:

$y=\frac{3}{2} x-6$

I hope this helps!

What is the value of x=2x + 9 = -27

Sergio039 [100]

<h3>I'll teach you how to solve 2x + 9 = -27</h3>

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

2x + 9 = -27

Subtract 9 from both sides:

2x+9-9 = -27-9

SImplify:

2x=-36

Divide both sides by 2:

2x/2 = -36/2

Simplify:

x= -18

Your Answer Is x= -18

plz mark me as brainliest if this helped :)
