Answer:

105 selection s

Step-by-step explanation:

Given:

The coach has to select 2 co-captains from the 15 girls out for soccer

n = 15

r = 2

The number of selections possible is;

N = nCr = n!/r!(n-r)!

Since no other is specified.

Substituting the values of n and r;

N = 15C2 = 15!/2!(15-2)!

N = (15×14)/2

N = 105

Therefore, she have 105 possible selections

0.1715

Step-by-step explanation:

From previous experience 340/1982 is the past probability that a person has high blood pressure.

The division of that leads to 0.1715 that the next person will have high blood pressure. That number is roughly (very roughly) 1 person in 6. So if 6 people come in 1 will have high blood presure.

A line passes through the points (2,21) and (8,27). Write a linear function rule in terms of x and y for
tatiyna
We have two points so we can find the gradient using y1-y2/x1-x2
gradient = 21-27/2-8
= 1
we know the form for any linear equation is y = mx + c
we have m and a point so we can substitute in point (2,21) to find c
21 = 1 x 2 + c
c = 19
therefore, the equation is y = x + 19
