VikaD [51]

Step-by-step explanation:

There are a total of 4 + 1 + 9 + 6 = 20 cookies.  So the probabilities of each type for a random cookie are:

P(oatmeal raisin) = 4/20 = 1/5

P(sugar) = 1/20

P(chocolate chip) = 9/20

P(peanut butter) = 6/20 = 3/10

Complete the sentence below. A function f is​ _____ on an open interval I​ if, for any choice of x1 and x2 in​ I, with x1less th
mojhsa [17]

Answer:

Increasing if f' >0 and decreasing if f'<0

Step-by-step explanation:

Difference quotient got by getting

\frac{f(x+h)-f(x)}{h} will be greater than 0 if function is increasing otherwise negative

Here h is a small positive value.

In other words, we find that whenever first derivative of a function f(x) is positive the function is increasing.

Here given that for x1, x2 where x1<x2, we have

if f(x1) <f(x2) then the function is decreasing.

Or if x1<x2 and if f(x1) >f(x2) for all x1, and x2 in I the open interval we say f(x) is decreasing in I.

Benito spent $1616 to operate his car last year. Some of these expenses are listed below. Benito's only other expense was for ga
Verizon [17]
Subtract all the operating expenses from the amount he spent total and get what's left over is $491.  That's what he spent on gas.  Divide the number of miles he drove by the amount he spent on the gas to find out what the average cost of the gas was per mile.  491/7270 = .06753.  But that is expressed in dollars and we need it in cents.  Multiply that decimal by 100 to get 6.75 cents, choice A from above.
