A treatment is administered to a sample of n = 9 individuals selected from a population with a mean of m = 80 and a standard dev
kupik [55]
Cohen's d is calculated according to the formula:
d = (mean difference) / standard deviation
0.5 = mean difference / 12
Therefore, mean difference = 6
Since we have a population mean of 80, the sample mean must be 80 + 6 = 86.

Will mark brainliest for having the steps.<br> prove tan(2x) = tan(x+x)
jonny [76]
So here is how we are going to prove that (2(tan x - cot x) / (tan^2 x - cot^2 x} = sin (2x). Follow it step by step:
LS = 2(tanx−cotx)
------------------
tan^2−cot^2x
= 2(tanx−cotx)
----------------------
(tanx−cotx)(tanx+cotx)
= 2
-------------------
(tanx+cotx)
= 2
-----------------
Sin2x+cos2x
---------------- sinxcosx
= 2
-------------
1
------------
sinxcosx
= 2sinxcosx
= sin2x

Tell whether the triangle with the given side lengths is a right triangle. Y/N question
melomori [17]

Answer:

Yes it is a right triangle.

Step-by-step explanation:

Because the Pythagorean Theorem states that a^{2} +b^{2} =c^{2}

85^{2}=7225\\84^{2}=7056\\13^{2}=169\\7056+169=7225

What is the greatest whole number that is less than ( 5\2)^3 divided by (3\4)^2
12345 [234]
First work out (5/2)³ by cubing both the numerator and denominator to give: 125/8

then work out (3/4)² by squaring both the numerator and denominator to give: 9/16 

then divide 125/8 by 9/16
using the stay-change-flip method of division:
the first term stays the same, the divide becomes multiply and the second fraction is flipped upside down.
so:
125/8 x 16/9 =2000/72
then just divide 2000 by 72 to give: 27.78 to 2 d.p
therefore the greatest whole number than 27.78 is 27.
