It depends on how many sided die it is

One die has a 5.
The only way to get a sum of 7 is by rolling a 2 on the other die.
The other die has 6 equally likely outcomes, the numbers 1, 2, 3, 4, 5, or 6.
The probability of rolling a 2 with one die is 1/6.

The answer is 1/6.

a. f(2)=24  

Step-by-step explanation:

Given function:

f(x)=3x^2+9x-6

To find f(2)

Solution:

In order to find f(2),we need to plugin input=2 i.e. the value of x=2 in the function and find the output by evaluating.

Plugging in x=2 in the given function.

f(2)=3(2)^2+9(2)-6

Evaluating.

f(2)=3(4)+18-6

f(2)=12+18-6

At a school fair 70% of the people are under 16 years old. One third of the people remaining are teachers. If there are 21 teach
Tamiku [17]
In the fairest school 70% are below 16 years old 1/3 are teachers which is equals to = 21 Let’s start solving: => 1/3 of 100% => 100 / 3 = 33.33% thus 33.33% = 21 => 21 x 3 = 63, is the total number of people in the school. Let’s try solving the number of people below 16 years old Have you notice that you are asking for a 70% of students but there are already 33.33% of teacher. Thus your given problem is not right already. => 100% - 33.33% = 66.67% that’s the only remaining percentage and not 70% => 63 * .6667 = 42.0021 Thus, there are around 42 people who are 16 years old younger.
