A physiological psychologist has performed an experiment to determine if a particular drug, smartozine, affects maze learning in

Elis [28]

Answer:

The critical value of F for this situation is 2.975.

Step-by-step explanation:

A test is being performed to determine if a particular drug, smartozine, affects maze learning in rats.

The groups are divided as follows:

Three groups of 8 rats each are injected with one of three different doses of smartozine.
The fourth group of 6 rats is injected with a saline solution as a control.

So, there were in total k = 4 groups with n = 30 rats.

The significance level of the test is, α = 0.05.

Compute the critical value of F as follows:

$F_{\alpha, (k-1, n-k)}=F_{0.05, (4-1, 30-4)}=F_{0.05, (3,26)}=2.975$

*Use the F-table.

Thus, the critical value of F for this situation is 2.975.

What is the angle of B

Charra [1.4K]

Y-9 + y/2 = 180
Add nine to each side
y+y/2=189
Multiply each side by two
2y+y=378
Add the y's together
3y=378
Divide it all by three
y=126

so, Angle B is 126 degrees

I hope that helps!

Can someone explain this I dont understand it

IrinaVladis [17]

Y = mx + b

m is your slope AKA rate of change
b is the y intercept.

from the graph we can see that the y intercept (b) is 15. (look at the y axis and see what point the line crosses on the y, here it is 15, in-between 10 and 20)

slope is rate of change. to figure this out remember slope = rise over run:

$slope = \frac{rise}{run}$

so pick two points. how much does one point rise after the other point you picked? In the graph it rises 1 square so rise = 1

Now looking at the same two points, how far away from each other are they on the x axis? Looking at the graph they are 2 squares away from each other. so run = 2

Now plug these numbers into the rise over run formula:

$slope \: = \frac{1}{2}$

Now we have everything we need to put into our formula for a line:

$y = mx + b$
$y = \frac{1}{2} x + 18$

For number 16 you should get:

$y = \frac{1}{5} x + 3$

after you do the same steps again yourself

[Right Triangles Only] SOHCAHTOA
[Right Triangles Only] cos∅ = adjacent over hypotenuse

Step-by-step explanation:

Step 1: Identify Variables

Angle measure = 58°

Adjacent side of angle = x

Hypotenuse = 9

Step 2: Solve for x

Substitute [cosine]: cos58° = x/9
Isolate x: 9cos58° = x
Evaluate: 4.76927 = x
Rewrite: x = 4.76927
Round: x ≈ 4.8
