Running times for 400 meters are normally distributed for young men between 18 and
30 years of age with a mean of 93 seconds and a standard deviation of 36 seconds.
what is the proportion of men having running times faster than 120 seconds? (hint:
remember running faster means the finishing time is a smaller number). round to 3
decimal places.

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.

h is the x-coordinate of the vertex

step-by-step explanation:

we have

in this function

the point represent the vertex of the function

so

h is the x-coordinate of the vertex

k is the y-coordinate of the vertex

15 / 2 = 7.5

100 / 7.5 = 13.
