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).
(0,3) and (10, 15)
slope = (15-3)/(10-0) = 12/10 = 6/5
b = 3
so equation
y = 6/5x + 3
answer
<span>A. Y=6/5x+3</span>
Y - y1 = m(x - x1)
slope(m) = 1/2
(6,-3)....x1 = 6 and y1 = -3
now sub...and pay attention to ur signs
y - (-3) = 1/2(x - 6)...not done yet
y + 3 = 1/2(x - 6) <=== ur answer
Answer:
14
Explanation:
The given triangle is a right-angled triangle. This means that special trig functions can be applied.
These functions are as follows:
sin θ = opposite / hypotenuse
cos θ = adjacent / hypotenuse
tan θ = opposite / adjacent
Now, we have:
θ = 40°
opposite = 12 m
adjacent is the distance we want to find
Substitute with the givens in the tan formula to get the distance as follows:
tan (40) = 12 / distance
distance = 12 / tan (40)
distance = 14.3 which is approximately 14 m
Hope this helps :)
