Answer: B)792

Step-by-step explanation:

Given: The number of people in basketball team = 12

To choose different five-person starting lineups , we will use combinations.

The number of different five-person starting lineups can be chosen  will be given by :-

^{12}C_5=\frac{12!}{(12-5)!5!}............[^nC_r=\frac{n!}{(n-r)!r!}}]\\=\frac{12\times11\times10\times9\times8\times7!}{7!\times5!}\\\\=\frac{12\times11\times10\times9\times8}{120}=792

Hence, 792 different five-person starting lineups can be chosen .

NO LINKS!!! Find the equation of the PARABOLA with a vertex at (-2, 6) and passing through the point (1, -3)​
levacccp [35]

General equation of parabola

  • y=a(x-h)²+k

for vertex(h,k)

Now

\\ \rm\Rrightarrow y=a(x+2)^2+6

  • Put (1,-3) and find a

\\ \rm\Rrightarrow -3=a(1+2)^2+6

\\ \rm\Rrightarrow -9=a(3)^2

\\ \rm\Rrightarrow -9=9a

\\ \rm\Rrightarrow a=-1

So

equation of parabola

\\ \rm\Rrightarrow y=-(x+2)^2+6

kaheart [24]

Here, Alicia is wrong because on evaluating 3 ^{1.4} we get 4.65554 which is of course less than 6. Zara's calculation could be;

3 ^{1.4}  \\  \\ 3 ^{ \frac{7}{5} }  \\  \\  \sqrt[5]{3 ^{7} }   \\  \\ 3 \sqrt[5]{3 ^{2} }  \\  \\ 3 \sqrt[5]{9}  \\  \\  = 4.6554

What is the probability of getting either blue or green on a spinner that is 3/10 greens and 1/5 blue?
Semmy [17]

Answer:

1/2 or 0.50

Step-by-step explanation:

To find the probability of getting either blue or green on a spinner, we must add both probabilities together.

\frac{3}{10}+\frac{1}{5}  = ?

To make adding our two fractions easier, we need to make sure they have like denominators.

\frac{1*2}{5*2} =\frac{2}{10}

Now that the denominators of our probabilities are the same, we can add them together to get our answer.

\frac{3}{10} +\frac{2}{10}=\frac{5}{10}

\frac{5}{10} =\frac{1}{2} or 0.50
