(c) There are seven days in a week. How many of them start with the letter 'T? What fractions of the days start with the letter 'T’?

Step-by-step explanation:

No of days in 1 week = 7

No. of days starting with T letter = 2

Now

Fraction of the days starting with the letter T

= 2 / 7

Hope it will help :)

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.
