Test scores on a statewide standardized test for a large population of students are
normally distributed with mean = 9.44 and standard deviation = 1.75. Certificates
are given to students who score in the top 2.5% of those who took the test. Fred, a
student who took the test, finds out that he earned a score of 13.1 on the test. He
will not get a certificate.
True
False

true is the answer

Step-by-step explanation:

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.

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.
