Mamont248 [21]

If there are 40 children aged twelve and under and x of them are under three years old, 40 - x aged three twelve years old. From the 92 people that where taken by the company on whale watching trips, 52 are over twelve years old. The equation that best show the total cost, C is
(40 - x)(36) + (52)(48) = C
Rearranging the equation gives,
x = 40 - ((C - 2496)/ 36)

2x^2 + 3x - 12 when x = 5 help pls

cluponka [151]

$\huge\textsf{Hey there!}$

$\mathsf{2x^2 + 3x - 12}$

$\mathsf{= 2(5)^2 + 3(5) - 12}$

$\mathsf{5^2}$

$\mathsf{= 5 \times 5}$

$\mathsf{\bf = 25}$

$\mathsf{2(25) + 3(5) - 12}$

$\mathsf{2(25)}$

$\mathsf{= \bf 50}$

$\mathsf{3(5)}$

$\mathsf{= \bf 15}$

$\mathsf{= 50 + 15 - 12}$

$\mathsf{50 + 15}$

$\mathsf{= \bf 65}$

65 - 12

$\mathsf{= \bf 53}$

Answer:

0.6804

Step-by-step explanation:

Given that Margie is practicing for an upcoming tennis tournament. Her first serve is good 20 out of 30 times on average.

Since each trial is independent and there are two outcomes, X no of good serves is binomial with n=6 and p =2/3

Required probability

= Prob that atleast four of 6 times good serve

= $P(X\geq 4)$

= $P(x=4,5 or 6)\\=1-F(3)\\=0.6804$

Formula used:

P(X=r) = $6Cr (\frac{2}{3}^r )(\frac{1}{3}^{6-r} )$
