Answer:

Choice C is correct.(f-g)(x) = -4x²+10x is the answer.

Step-by-step explanation:

We have given two functions:

f(x) = -x²+6x-1

g(x) = 3x²-4x-1

We have to find (f-g)(x) = ?

(f-g)(x) = f(x) - g(x)

Putting values in above formula we get,

(f-g)(x) =(-x²+6x-1) - ( 3x²-4x-1)

(f-g)(x) = -x²+6x-1-3x²+4x+1

(f-g)(x) = -4x²+10x

For this case we have that given two functions, f (x)and g (x), then(f-g) (x)is given by:

(f-g) (x) = f (x) -g (x)

So:

f (x) = - x ^ 2 + 6x-1\\g (x) = 3x ^ 2-4x-1

We have to:

(f-g) (x) = - x ^ 2 + 6x-1- (3x ^ 2-4x-1)\\(f-g) (x) = - x ^ 2 + 6x-1-3x ^ 2 + 4x + 1\\(f-g) (x) = - 4x ^ 2 + 10x\\

Answer:

(f-g) (x) = - 4x ^ 2 + 10x

For an independent-measures research study (i.e., independent measures t Test), the data show an 8-point difference between the
zloy xaker [14]

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:

S=\sqrt{S^2}\\S=\sqrt{16} \\S= 4

Therefore, the value of Cohen's d (d) is:

d=\frac{M_{2} -M_{1}}{S} \\d=\frac{8}{4}\\d=2
