There are 32
students in Mr. Morgan’s math class. One student will be randomly selected to present his/her project.
If there are 20 boys and 12 girls in the class, what is the probability that the presenter will be a boy?

the boys percentage of getting picked are 63% while the girls are 38%

Step-by-step explanation:

There is a 62.5% chance that a presenter will be a boy.

Step-by-step explanation:

Divide the number of boys by the number of total students. Like when you find a percentage on a test.

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.

27 + 13x + 15 = (x + 5)( =

step-by-step explanation:

27 + 13x + 15 = (x + 5)( = 27 + 13x + 15 = (x + 5)( = 27 + 13x + 15 = (x + 5)( =
