A new truck sells for $28,000depreciates (decreases in value) 13% each year. What is the Decay Factor, b?
sleet_krkn [62]
Not sure
te rate is r
for decay, it is
A=P(1-r)^t
r=rate
P=present amount
dunno what b is
but I guess
A=28000(1-0.13)^t
A=28000(0.87)^t
I would guess the decay factor would be 0.87

Mr.Traynor's class is taking a field trip to the zoo.The trip will cost $26 for each student.There are 22 students in her class.
marta [7]
A good estimate would be $500 because if I round $26 to $25 and 22 to 20, 20x25=500

Find the cumulative frequency
aleksandrvk [35]

We get the cumulative frequency as:

                3

                7

               13

               22

               29

               36

               37

We are given the data:

Daily Low(°F)    Frequency

 35 - 39                    3

 40 - 44                    4

 45 - 49                    6

 50 - 54                    9  

 55 - 59                    7

 60 - 64                    7

 65 - 69                     1

We have to find the cumulative frequency of the data.

We will do this by adding the data values of previous interval.

Daily Low(°F)    Frequency     cumulative frequency

 35 - 39                    3                              3

 40 - 44                    4                              7

 45 - 49                    6                             13

 50 - 54                    9                             22

 55 - 59                    7                             29

 60 - 64                    7                             36

 65 - 69                    1                              37

Therefore, we get the cumulative frequency as:

                3

                7

               13

               22

               29

               36

               37
