Some IQ tests are standardized to a Normal model N(100,18). a) What cutoff value bounds the highest 5% of all IQs? b) What cutoff value bounds the lowest 20% of the IQs? c) What cutoff values bound the middle 70% of the IQs?

i believe the answer is d.

hope it you! : d

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.

since no one answered yet i will give it a shot, not completely sure tho.

i think it should be y=cos(x+2pi), (third answer, answer c)

good luck.
