Answer:

C) 24

Step-by-step explanation:

we know that 18 students is 75% of the class and we need to know 100% of the class. to calculate this, divide the 18 students by 75% to work out what 1% of the students equals:

18 ÷ 75 = 0.24

0.24 students = 1% of the class. multiply this number by 100 to calculate 100% of the class:

0.24 x 100 = 24

∴ there are 24 students in Ms. Perron's class

I hope this was helpful :-)

$x ^{3} - 3x - 2$

x³-2x²+2x²-3x-2

x²(x-2)+2x²-4x+1x-2

x²(x-2)+2x(x-2)+1(x-2)

(x-2)(x²+2x+1)

(x-2)(x+1)(x+1)is a required answer.

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