Aset of data items is normally distributed with a mean of 270 and a standard deviation of 36. convert 270 to a z-score.

f(x) is going down by 4

step-by-step explanation:

(its either that or its going left by 4)

he earned 78.75 in interest.

step-by-step explanation:

a, b, c, d are correct.

step-by-step explanation:

we have g(x) = 3 and are required to find which option is a translation of g(x).

now, 'translation' is a transformation which means to shift the function in any direction and the general form of translation is g(x) + k, where k is any real number.

so, according to the options we see that all are correct as they satisfy the general form of translation.

also, it can be seen from the graph below that the function g(x) = 3 is shifted from its position in all the four options.
