A university has 33,660 students. In a random sample of 180 students, 12 speak three or more languages. Predict the number of students at the university who speak three or more languages.

2244

Step-by-step explanation:

Divide 33660 by 180, Then when you get your quotient multiply that by 12 , which gives you 2244

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.
