Answer:
The value of K is 5
Step-by-step explanation:
I reversed it.
The tiny squares means 90⁰, so 90+49=139
All of these angles add up to 180⁰
So 180-139=41
The k equation equals 41⁰, so reverse it to find answer
41-1=40
40÷8=5
Answer:
8 should be multiplied in the parenthesis
Step-by-step explanation:
8(9 + x) = 192
72 + 8x = 192
8x = 120
x = 4
Answer:
C. 2
Step-by-step explanation:
Cohen's d is a parameter used to express the standardised difference between two means. It is defined as the difference between the means divided by the pooled standard deviation.
In this case, the difference between both means (M2-M1) is 8. As for the pooled standard deviation, simply take the square root of the given pooled variance:
Therefore, the value of Cohen's d (d) is:
3(13-2a)=-3+a
39-6a=-3+a
42=7a
a=6
