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.
The first one should be read as between 75 and 97 inclusive. That means you are using ≤
75 ≤ x ≤ 97 As a compound inequality this is
75 ≤ x ; x ≤ 97
The second one is just a bit harder. That's because a place in Ohio probably could go down to - 36. Again, both ends of the inequality use ≤
-36 ≤ x ≤ 20 As a compound inequality
-36 ≤ x; x ≤ 20
I'm not sure if you should be including units like 20°F. If you are, add them in.
Answer:
, so using order of applications, it simplifies to 27+1.5+9 after multiplying and dividing, and the final answer is 37.5
Step-by-step explanation:
Answer: The total amount the water change was -28 gallons by the end of the week <u>OR</u> The total amount the water changed decreased 28 gallons by the end of the week. Depending on how you want to word it.
Hope this helps!
Step-by-step explanation:
<u>Create you equation:</u>
x = the total amount the water changed
d = the amount of days
x = -4d
<u />
<u>Insert the known information into the equation and solve:</u>
x = -4d
x = -4(7)
x = -28
The answer is <span>-(3/4) and 3/4</span>
