Anumber wheel is divided into 15 equally-sized segments. each segment is numbered 1 through 15. if amelie s
wheel, what is the probability that the number will be a 4, 5, 6, or 7?
a. 33.3%
b. 26.7%
20%
d. 13.3%
e. 6.7%

B)  P(E) = 26.7%

Step-by-step explanation:

Probability of an event E =

Now, here let E be the event of getting a number 4,5,6 or7.

Total Outcomes = 15

So, P(E) = favorable Outcomes / Total Outcomes =  

⇒ P(E)= 0.2666

or P(E) 0.266 x 100 =    26.7 %

So, B is the correct option.

  b.   the average rate of change of f(x) is less than the average rate of change of g(x).

step-by-step explanation:

since the length of the interval is the same in each case, we only need to compare the change in y-value to see which is greater.

so the change in y-value for function f is (6 )) = 9.

the table tells us

so the change in y-value for function g is (31 -1) = 30.

the change in y-value of f(x) on the interval is less than the change in y-value of g(x) on the same interval, so the average rate of change of f(x) is less than the average rate of change of g(x).

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
