83 students choose to attend one of three after school activities: football, tennis or running. There are 53 boys. 36 students choose football, of which 6 are girls. 15 students choose tennis. 18 girls choose running. A student is selected at random. What is the probability this student chose running? Give your answer in its simplest form.

38.55% or 32/83

Step-by-step explanation:

First of all, we need to write down the amount of students in each activity:

Football = 36

Tennis = 15

Running = 18 girls + 14 boys (the remainder of the 83 students) so 32 students.

So 32/83 as a percentage is 38.55%

Thus, the chance of the randomly selected student being in the Running category is 38.55% or 32/83.

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be
