Answer:

P(X=x)=0.0004928

Step-by-step explanation:

-This is a binomial probability problem.

-Given the probability of catching a cold is 0.03, n=6

#The probability of exactly 3 people catching a cold is calculated as:

P(X=x)={n\choose x}p^x(1-p)^{n-x}\\\\P(X=3)={6\choose3}0.03^3(1-0.03)^3\\\\=0.0004928

Hence, the probability of exactly 3 in 6 people catching a cold is 0.0004928

Find the y-intercept of 2x - 3y = 6
Ksju [112]

Answer:

(0, - 2)

Step-by-step explanation:

The y-intercept is the value of y when x = 0. Substitute 0 for x in the equation and solve for y.

2x - 3y = 6

2(0) - 3y = 6

- 3y = 6

\frac{ - 3y}{ - 3}  =  \frac{6}{ - 3}

y =  - 2

When x = 0, y = - 2.
