Answer:
none of the above
Step-by-step explanation:
cohen's d= (Mean of population - mean of sample)/ standard deviation of population
0.5 = (80-mean of sample)/12
Mean of sample= 74
Answer: I believe this will be your answer for this.

Answer:
Therefore the measure of the central angle is 45.86°.
Step-by-step explanation:
Given:
Radius = 9 cm
arc length = 7.2 cm
pi = 3.14
To Find:
Central angle = θ =?
Solution:
If the θ measured in degree then the arc length is given as
Where r = radius, θ = Central angle
On substituting the values we get
Therefore the measure of the central angle is 45.86°.
The factors of this equation are x = sqrt(6), x = -sqrt(6) and x = -5.
In order to find these by grouping, we start by just taking the first two terms. We then pull out the greatest common factor.
x^2 + 5x^2
x^2(x + 5)
Now we do the same for the last two.
-6x - 30
-6(x + 5)
Since the two parenthesis left behind are exactly the same, we can use them along with the factors pulled out, multiplied together.
(x^2 - 6)(x + 5)
Now to find the factors, we simply set both parenthesis separately equal to 0.
x + 5 = 0
x = -5
x^2 - 6 = 0
x^2 = 6
x = +/-sqrt(6)
