Answer:
2
Step-by-step explanation:
The slope (m) can be found using the formula ...
m = ∆y/∆x = (y2 -y1)/(x2 -x1)
= (1 -(-5))/(4 -1) = 6/3
m = 2
The slope of the line is 2.
Line BD and MK are parallel to each other.
The answer is 1/4 or 0.25.
steps:
first look in the parenthesis and notice that the denominator is not the same. set the denominator to 6 for the fraction 1/3 by multiplying 3(2) and 1(2) which makes the fraction 1/6. now add -5/6 and 1/6 inside the parenthesis. you should get -3/6 which you should put in the simplest form: -1/2. now combine -1/2 and -1/2 to get 1/4
A 1 = - 32, a 9 = - 120
a 9 = a 1 + 8 d
- 120 = - 32 + 8 d
8 d = - 88
d = - 88 : 8
d = - 11
a 32 = a 1 + 31 d = - 32 + 31 * ( -11 ) = - 32 - 341 = - 373
Answer: B ) - 373
Answer:
0.125
Step-by-step explanation:
Cohen's d is used to measure the effect size. Larger the value of Cohen's d, larger the effect between two observations.
It is determined by the formula,
where M₂ is Mean of 1st group
M₁ is the Mean of the 2nd group.
Here, M₁ = 46, M₂ = 48 and Standard deviation = 16
∴
⇒ d = 0.125
