Arecent survey of local cell phone retailers showed that of all cell phones sold last? month, 64% had a? camera, 28% had a music player and? 22% had both. what is the probability that a cell phone sold last month had a camera or a music? player?

The probability of having a cell phone with either a camera or a music player is simply the sum of their probabilities minus the probability of having both.

P (camera or music player) = 64% + 28%  - 22% = 70%

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.
