There are 20 members of a basketball team.

spin [16.1K]

Answer:

a)125970

b)95040

c)35640

Step-by-step explanation:

a) selecting 12 player from 20 players can be one in $^{20} C_{12}$

$^{20} C_{12}$ = $\frac{20!}{12!X (20-12)!}$

= $\frac{20!}{12!X8!}$

= $125970$

b) since each position has an identity permutations can be used so

Number of ways = $^{12} P_{5}$

= $\frac{12!}{(12-5)!}$

= $\frac{12!}{7!}$

= $95040$

c) coach permutes 4 players for position other than centers in $^{12}P_{4}$ ways and selects center in 3 ways

so, number of ways = $^{12}P_{4}X3$

= $\frac{12!}{8!}X3$

= $35640$

Select all of the statements that are true for the given parabola.

Naddik [55]

Answer:

A & D

Step-by-step explanation:

The parabola opens up, so the minimum value of y is at the point (1, -2) and the graph passes thru the x-axis at 3 and -1, so those are the x-intercepts.

The axis of symmetry is x = 1, not y = -2 and the graph never has a maximum value. Parabolas that open up never have a maximum value.
