Sat scores are normally distributed, with a mean of 500 points and a standard deviation of 100 points. suppose you take the sat. several weeks later, you receive your results, which show that you reached the 90th percentile for the math portion. recalling that sat scores are always expressed as multiples of 10, how many points did you get on the test?

45

step-by-step explanation:

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.
