Answer:
For the interpretation we consider a value for d small is is between 0-0.2, medium if is between 0.2-0.8 and large if is higher than 0.8.
And on this case 1.713>0.8 so we have a large effect size
This value of d=1.713 are telling to us that the two groups differ by 1.713 standard deviation and we will have a significant difference between the two means.
Step-by-step explanation:
Previous concepts
The Effect size is a "quantitative measure of the magnitude of the experimenter effect. "
The Cohen's d effect size is given by the following formula:
Solution to the problem
And for this case we can assume:
the mean for females
the mean for males
represent the deviations for both groups
And if we replace we got:

Use law of cosines
o^2=p^2+q^2-2pqCos(C)
o^2=38^2+29^2-38*29Cos(39)
o^2=1444+841-1712.83
o^2=572.17
o=23.92
Say 24 cm
Answer:
-3x^2+7x+6
Step-by-step explanation:
1,099 square inches.
formula for surface area of cylinder:
2 π r^2 + 2 π rh
π = 3.14
Use formula with given dimensions:
2 • 3.14 • 5^2 + 2 • 3.14 • 5 • 30 = 1,099
Final answer: 1,099 square inches
(NOT ROUNDED)
Have a nice day!
Answer:
41
Step-by-step explanation:
Applying Pythagoras theorem since it is a right angled triangle.
(Hypotenuse)^2=(base)^2+(perp)^2
Hyp^2=(9)^2+(40)^2
Hyp^2=81+1600
Hyp^2=1681
Taking sq root on both sides
Hypotenuse=41
