Answer:

B, C, D, E

Step-by-step explanation:

I just substituted the pairs in so

14 = 6(3) - 4(1)

14 = 18 - 4

14 = 14 yes that works

let's try another pair just so you see

14 = 6x - 4y

14 = 6(-1) - 4(-5)

14 = -6 - (-20)

14 = 14 yes that works

14 = 6(1) - 4(-2)

14 = 6 - (-8)

14 = 14 yes that works

14 = 6(14) - 4(-4)

14 = 84 - (-16)

14 = 100 nope

14 = 6(4) - 4(2.5)

14 = 24 - 10

14 = 14 yes that works

Answer:

The probability of getting 2 or fewer women when 10 people are picked

P(x≤ 2) = $\frac{56}{1024} = 0.0546$

Step-by-step explanation:

The participants in a television quiz show are picked from a large pool of applicants with approximately equal numbers of men and women

That is probability of participants of television quiz of equal numbers of men and women that is 50 %of men and 50% of women.

p = 50/100 = 1/2

q = 1-p = 1 - 1/2 = 1/2

n =10

we will use binomial distribution $p(x =r) = n_{cr} p^{r} q^{n-r}$

The probability of getting 2 or fewer women when 10 people are picked

P(x≤ 2) = P(x=0)+P(x=1)+P(x=2)

= $10_{c0} \frac{1}{2} ^{0} (\frac{1}{2}) ^{10-0}+ 10_{c1} \frac{1}{2} ^{1} (\frac{1}{2}) ^{10-1 \\$ + $10_{c2} \frac{1}{2} ^{2} (\frac{1}{2}) ^{10-2$
