Answer:

32

Step-by-step explanation:

In order to find the measure of angle A we must first find x

If you didn't know, supplementary angles add up to equal 180

Hence, 2x - 16 + 5x + 28 = 180

( Note that we just created an equation that we can use to solve for x )

We now solve for x using the equation that we created

2x - 16 + 5x + 28 = 180

Combine like terms

7x + 12 = 180

Subtract 12 from both sides

7x = 168

Divide both sides by 7

We're left with x = 24

Now to find Angle a

To find Angle A we simply substitute 24 for x in 2x - 16

* Substitute 24 for x *

2(24) - 16

Multiply

48 - 16

subtract

/_ A = 32

If probability of catching a cold is 0.03, what is the probability of 3 people out of six catching a cold?
xeze [42]

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
