A computer battery is found to have a mean time between charges of 13 hours. A modification is made which is supposed to increase battery life. Test on a random sample of 35 modified computers resulted in mean battery life of 13.6 hours with a standard deviation 0.5 hours. At the 95% confidence level, test the claim that the mean time between charges is longer after the modification.

i don't know but sry

Step-by-step explanation:

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.

i think the answer is d im not sure
