lesya692 [45]

Answer:

\sqrt{74}

Step-by-step explanation:

<u>Distance between two points</u>

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

\textsf{let}\:(x_1,y_1)=(2,-6)

\textsf{let}\:(x_2,y_2)=(7,1)

d=\textsf{length of segment AB}

Substituting points into the distance formula and solving for d:

\implies d=\sqrt{(7-2)^2+(1-(-6))^2}

\implies d=\sqrt{5^2+7^2}

\implies d=\sqrt{25+49}

\implies d=\sqrt{74}

Out of 50 basketball players trying to make a team, 5 will be chosen. 36 of the 50 are seniors and the remaining players are jun
AveGali [126]

Answer:   5503680

Step-by-step explanation:

The coach wants  2 senior out of 36 so he have

C₃₆,₂   =  36!/( 36 - 2 )!     = 36*35*34!/34!    =  36 * 35   = 1260

possibilities

Now he also wants 3 juniors out of 14

C₁₄,₃  =   14!/ (14- 3)!      =  14*13*12*11!/11!     =  14*13*12  = 2184

Now for each pair of senior (from 1260 outcomes) coach has 2184 possiblities therefore

Coach has

2184 * 1260 = 2751840    possibilities to choose from

Again as there are 2 senior to choose for captain we have to multiply by 2 to get the total  ways the team could be

2751840*2  = 5503680
