Answer:

a. 5.26

Step-by-step explanation:

As, the standard deviation of the distribution of the difference between mean is 0.76 so the t score will be simply calculated by dividing the difference of means by standard deviation of the distribution of the difference between mean as hypothesized difference is zero.

t score=Xbar A- Xbar B/Sd of difference of means

t score=55-51/0.76

t score=4/0.76=5.26

What is the value of k in the function ƒ(x) = 108 – kx if ƒ(–4) = 124?
ruslelena [56]

Answer:

4

Step-by-step explanation:

If f(x)= 108-kx, then all you have to do is plug in the given value of x which is -4, then equal it to the given value of 124.

108 - kx = 124\\108 - k(-4) = 124\\\\108 + 4k = 124\\\\4k = 124 - 108\\\\k = 16/4\\\\k = 4
