Answer:
B). F(1, 12) = 16.00
Step-by-step explanation:
'ANOVA' is a measure employed for 'analysis of a variance' in a given set of data of treatments or populations. While t-test helps in comparing their means.
As per the question, the F-ratio using ANOVA would be 'F(1, 12) = 16.00.' In order to calculate the variances, the distinction among the samples. The б^2 denotes the difference of representative means which is augmented by n(in case of samples being same). So, the ratio of F(1, 12) would be б^2 i.e. 4^2 = 16 since the sample sizes are distinct. Thus, <u>option B</u> is the correct answer.
Hello there!

Explanation:
↓↓↓↓↓↓↓↓↓↓↓↓↓
I gave you a hint.
You had to used PEMDAS.
P-Parenthesis
E-Exponents
M-Multiply
D-Divide
A-Add
S-Subtract
First you had to calculate with parenthesis first.


Then you calculate with exponents.


You had to multiply and divide you had go to left to right.


Then you add or subtract you had go to left to right.

Answer:
(3,0)
Step-by-step explanation:
Co-ordinates of J =(4,3)
Co-ordinates of K = (2,-3)
Midpoint formula :
= 
<u>Coordinates of the midpoint M </u><u>(3,0)</u>
The formula of a function is the rise over run.
The slope would be 2/5.
