K is the number of groups in one way ANOVA. Since here 4 groups involved. So k here is four.
<u>Explanation:</u>
In statistics, one-way analysis of variance is a technique that can be used to compare means of two or more samples. This technique can be used only for numerical response data, the "Y", usually one variable, and numerical or categorical input data, the "X", always one variable, hence "one-way".
The one-way analysis of variance (ANOVA) is used to determine whether there are any statistically significant differences between the means of two or more independent (unrelated) groups (although you tend to only see it used when there are a minimum of three, rather than two groups).
Answer:
can i please have somepoints
Step-by-step explanation:
i need to get an answer to a question and if i don't i might fail a really hard test
Michael must've rounded 500 to 600, and 754 to 800, which means there's an approximate difference of 200 between their scores.
The answer is:
940

70
Here's my work:
<span><span><span>949/70</span></span>=<span><span><span><span>70t/</span>70</span></span>
-</span></span>Cross-multiply.<span><span><span><span>
949/70</span></span></span>=<span><span><span><span>70t/</span>70</span></span></span></span><span><span><span>
(949)</span>*<span>(70)</span></span>=<span><span>70t</span>*<span>(70)
</span></span></span><span>66430=<span>4900t</span></span>
-Flip the equation.
<span><span>4900t</span>=66430</span>
-Divide both sides by
4900.<span><span><span><span><span>4900t

Hope this helps:)
Answer:
Tuesday
Step-by-step explanation:
Let the days of the week be numbered 1–7, starting with Monday and ending with Sunday. Let <em>t</em> represent today. We can equate the number of skirts finished by Friday (day 5) with the ones finished by Sunday (day 7) at the lower rate. (days × (skirts/day) = skirts)
... (5-t)×5 = (7-t)×3
... 25 -5t = 21 -3t . . . . . eliminate parentheses
... 4 = 2t . . . . . . . . . . . . add 5t-21
... 2 = t . . . . . . . . . . . . . divide by 2
Day 2 corresponds to Tuesday.
_____
<em>Check solution</em>
(5-2)·5 = 15 = (7-2)·3 skirts are being made.
