Let A be the event that there are at least two fives among the four rolls. Let B be the event that there is at most one five among the four rolls. Find the probabilities P(A) and P(B) by finding the ratio of the number of favorable outcomes to the total (i.e., P(A) = #A #Ω and P(B) = #B #Ω ).

Answers

Answer 1

Answer:

P(A) = 31/1296

P(B) = 125/1296

Step-by-step explanation:

Here, we want to find P(A) and P(B)

Let’s start with A

In a roll of a die, the probability that there will be a 5 is 1/6

The probability of not having a 5 is therefore 1-1/6 = 5/6

So out of four rolls , we want to find the probability of having at least two fives

This means there could be 2, 3 or 4 fives;

For two fives;

We have 2 fives and two non-fives

= (1/6 * 1/6 * 5/6 * 5/6) = 25/1296

For 3 fives;

we have 3 fives and 1 non five

= 1/6 * 1/6 * 1/6 * 5/6 = 5/1296

For 4 fives;

= 1/6 * 1/6 * 1/6 * 1/6 = 1/1296

So the probability of at least two fives is;

1/1296 + 5/1296 + 25/1296 = 31/1296

Event B is the probability that there is at most one five among the four rolls

That means there are 3 non fives and 1 five

P(B) = 1/6 * 5/6 * 5/6 * 5/6 = 125/1296

The American Academy Dermatology says that hair grows about 6 inches per year. How much hair can you expect to grow after 3 years, given that you do not get any haircuts.

Answers

About 18 inches / 1 foot and 6 inches

If hair grows about 6 inches every year, and we want to find out how much will grow in 3 years, we multiply.

6 x 3 = 18 inches

Then we can simplify it because there are 12 inches in a foot

18/12 = 1 6/12

When we evaluate the quotient functions, (mn)(x) for x = -3

(mn)(-3) = 9 and (m/n) (x), x ≠ 0

How did we evaluate the quotient function?

To evaluate the quotient function (mn)(x) for x = -3, we  substituting x = -3 into the function mn(x).

This gives us (mn)(-3) = m(-3) × n(-3) = (-3)² × (-3) = 9.

We then need to evaluate (m/n)(x), x ≠ 0.

This is done by dividing the function m(x) by the function n(x). This gives us (m/n)(x) = m(x) / n(x) = x^2 / x = x. However, this expression is undefined when x = 0, because division by zero is undefine

Answers

Answer: 24100

Step-by-step explanation:

The money in the account after 8 years is $24068.631.

Given that, principal=$19000 and the rate of interest=3%.

What is the formula to find the compound interest?

The formula to find the compound interest is CI=A-P.

Where, A=Amount that is [tex]A=P(1+\frac{r}{100} )^{n}[/tex], P=principal.

Now, [tex]A=19000(1+\frac{3}{100} )^{8}[/tex]

=19000×1.26677008139

What is the slope of a line perpendicular to the line whose equation is

Answers

Answer:
Mperpendicular=6
Pls mark me brainliest

The slope of a line would be -6 which is perpendicular to the line whose equation is 2x+12y=−192.

What is the slope of the line?

The slope of a line is defined as the angle of the line. It is denoted by m

Slope m = (y₂ - y₁)/(x₂ -x₁ )

We have to determine the slope of a line perpendicular to the line whose equation 2x + 12y = −192.

First, we have to find the slope of the given line

The equation of the line which is given as

2x + 12y = −192

12y = −192 - 2x

Divided by 12 both sides of the above equation to get the slope-intercept form

y = - (1/6)x - 16

Here the slope of the line (m) = -1/6

So the slope of the line perpendicular to the line will be: 1/m = 1/(-1/6) = - 6.
