d) If you buy 500 lottery tickets, what is the probability that you will get at least one $10 winner? B

Answers

The probability of each event will be

a. 0.122

b. 0.1

c. 0.64

d. 0.63

Probability of a $2 winner is 1 in 10

Probability of a $5 winner is 1 in 50

Probability of a $10 winner is 1 in 500

The formula to find probability is

1. no. of favorable outcomes / total no. of favorable outcomes

                                                  OR

2. P(A) = n(A)/n(S)

where

P(A) is the probability of an event “A”

n(A) is the number of favorable outcomes

n(S) is the total number of events in the sample space

Now we will use formula to find probability of different events happening

a. To find the probability of getting either a $2, or $5, or $10 winner we

will find probability of $2 , $5 and $10 and add them together.

1/10 + 1/50 + 1/500 = 0.122

b. The probability of getting a $2 winner will be

1/10 = 0.1

c. The probability of getting no $5 winner is (49/50)^50 = 0.36

So the probability of getting $5 winner will be 1 - 0.37 = 0.64

d. The probability of getting no $10 winner is (499/500)^500 = 0.37

And we can take probability of total no. of outcomes as 1.

So the probability of getting $10 winner will be 1 - 0.37 = 0.63

a store increased the original price of a shirt by a certain percent and then decreased the new price by the same amount. given that the resulting price was 84% of the original price, by what percent was the price increased and decreased?

Answers

A retailer raised a shirt's original price by a certain percentage before lowering it by the same percentage. The price was increased and decreased by 40% as the final cost was 84% of the initial cost.

What is percent?

In essence, percentages are fractions with a 100 as the denominator. We place the percent symbol (%) next to the number to indicate that the number is a percentage. For instance, you would have received a 75% grade if you answered 75 out of 100 questions correctly on a test (75/100). A number or ratio that can be expressed as a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The percentage therefore refers to a part per hundred. Per 100 is what the word percent means. The letter "%" stands for it.

Here,

Let's say the shirt originally cost Rs 100, and we're adding t% to the price.

The new price of the shirt is therefore 100 + (t/100 * 100) = Rs. 100+t after the initial t% increase.

The price is then reduced by t%.

Cost of a new shirt: (100 + t) - (t/100)

[100+t] = (100+t)

[1-(t/100] = [(100+t)/100]

therefore, the final price is equal to 84% of Rs 100, or Rs 84.

10000 - t^2 = 84.

t^2 = 1600

 t = 40

The price was thus raised and lowered by 40%.

The original price of a shirt was increased by a specific percentage before being decreased by the same percentage by the retailer. As the final price was 84% of the initial price, the price was both increased and decreased by 40%.

Given:

The technician at the store worked on the computer for 5.25 hours and charged her $133 for parts.

Total charged = 579.25

Let x be the charge per hour.

so the equation = 5.25x + 133 = 579.25.

Technician charge  = 579.25 - 133 = 446.25

5.25 hours = 446.25

divide by 5.25 on both sides

5.25 hours / 5.25 = 446.25/5.25

when two pipes fill a pool together, they can finish in 4 hours. if one pipe fills half of the pool and then the other takes over and finishes filling the pool, the pool will fill in 9 hours. how long would it take each pipe to fill the pool if it were working alone?

Answers

Time taken by pipe 1 to fill the pool is 6 and by pipe 2 is 12.

Here we have to find the time taken by each pipe to fill the pool.

Formula to find the work:

w = r × t

where

w =  is the work done

r = is the rate of work done

t =  is the time taken to do the work

For pipe 1 working alone to fill 1 pool, the work done is 1

w1 = r1 t1

1 = r1 × t1

t1 = 1/r1

For pipe 2 working alone to fill 1 pool, the work done is 1;

w2 = r2 t2

1 = r2 × t2

t2 = 1/r2

From the question, it would take 9 hours if each pipe took turns filling half the pool. That is;

t1/2 + t2/2 = 9

t1 + t2 = 18

However, if both pipes worked together, it would take 4 hours for each pipe. That is;

w1 + w2 = w

r1t1 + r2t2 = 1

4r1 + 4r2 = 1

r1 + r2 = 1/4

As we know from the above:

r1 = 1/t1 and r2 = 1/t2

So;

1/t1 + 1/t2 = 1/4

(t2 + t1)/ t1 t2 = 1/4

t1 + t2 = 18

So

t1 t2 = 72

The only factors of 72 that satisfy the conditions

t1 + t2 = 18

t1 . t2 = 72

are 6 and 12.

Therefore, pipe 1 will take 6 hours, and pipe 2 will take 12 hours.

4) The "random walk theory of stock prices holds that price movements in disjoint time periods are independent of each other. Suppose that we record only whether the price is up or down each year, and that the probability that our portfolio rises in price in any one year is 0.65.



a) What is the probability that the portfolio goes up for 3 consecutive years?



b) What is the probability that the portfolio's value moves in the same direction (either up or down) for 3 consecutive years?



c) What is the probability that the portfolio's value goes up for at least 1 of 3 years?​

Answers

Part (a)

Each year is independent of any other. This allows us to simply multiply the probability values for each increase. Recall that P(A and B) = P(A)*P(B) if and only if events A & B are independent.

(0.65)*(0.65)*(0.65) = (0.65)^3 = 0.274625

Answer: 0.274625

=========================================

Part (b)

We calculated the probability of an increase for each of the 3 years back in part (a). Let's calculate we have a decrease 3 times in a row.

0.65 is the probability of increase for any given year, which makes 1-0.65 = 0.35 the probability of decrease for any given year.

Therefore (0.35)^3 = 0.042875 represents the probability of 3 decreases in a row.

Add this result to what we got in part (a)

0.274625+0.042875 = 0.3175

This is done because we could have 3 increases OR 3 decreases (pick one). Think of it like this P(A or B) = P(A) + P(B) where A & B are mutually exclusive events.

Answer: 0.3175

=========================================

Part (c)

In the previous part we calculated 0.042875 as the probability of 3 decreases in a row.

1-0.042875 = 0.957125 is the probability of at least one increase. Note how the events "no increases" and "at least one increase" are complementary events. They are opposite. One or the other must happen, which allows us to subtract from 1.

You can think of it like this

P(no increases) + P(at least one increase) = 1

P(at least one increase) = 1 - P(no increases)

Answer: 0.957125

The pair of points (−6, y) and (4, 8) lie on a line with a slope of 5/2. Set up and solve for the missing y-value using the slope formula. Show all work to receive credit.

Answers

Given the slope of the line and the pair of points, the missing y - value can be found to be - 17

How to find the missing y - value?

The slope formula is:

y = Slope(x) + y - intercept

Using the point (4, 8), the y - intercept can be found by the formula:
8 = 5/2 (4) + y - intercept

y - intercept = 8 - 10

y - intercept = -2

The missing y value is therefore:

y = Slope(x) + y - intercept

= -6 (5/2) - 2

= -15 - 2

= - 17

a croissant shop has plain croissants, cherry croissants, chocolate croissants, almond croissants, apple croissants, and broccoli croissants. how many ways are there to choose ) two dozen croissants with at least two of each kind?

Answers

There are 6188 ways are there to choose two dozen croissants with at least two of each kind.

A combination is the combination of two or more distinct things. Although it is not necessary to combine things in pairs, the term "combining" comes from the Latin word for "joining together two by two."Combination repetition is permitted.

There are six different varieties of croissants (n = 6), and we must select two dozen croissants (r = 12) with at least two of each type.

In combination, The order does not matter and repetition is allowed.

thus, according to combination,

[tex]C( n+ r - 1,r) = \frac{(n + r - 1 )!}{r! (n-1)!} \\\\C( 6+ 12 - 1,12) = \frac{(6 + 12 - 1 )!}{12! (6-1)!} \\\\ = \frac{17!}{12!5!} \\= 6188[/tex]


thus, there are 6188 ways possible to choose two dozen croissants with at least two of each kind.

Graph the line that represents a proportional relationship between d and t with the property that an increase of 5 units in t corresponds to an increase of 8 units in d.

What is the unit rate of change of d with respect to t? (That is, a change of 1 unit in t will correspond to a change of how many units in d?)

The unit rate is

?

Graph the relationship.

Answers

The unit rate of change , d with respect to t is =  1.6  .

In the question,

it is given that ,  the relationship between d and t is proportional

also given that "  increase of 5 units in t corresponds to increase of 8 units in d ".

which is represented as 5t = 8d

Divide both sides of the equation  5t = 8d by "5" ,

t = 8/5d

t = 1.6d

next we plot the graph of t = 1.6d

we see that the above equation is a proportional linear equation

and A proportional linear equation is represented as

t = md , Where m represents the unit rate .

So , after comparing , we get

m = 1.6

0.25 in standard form

Answers

Answer:

2.5 × 10^-1

step-by-step explanation:

To get to standard form, you must move the decimal to the right one place so the number before it is not a 0. Because you move the decimal, you must add the second part of the equation so that the value does not change.

Answer:

02.5 but the 0 at the beginning isn't significant so 2.5

Step-by-step explanation:

because to find the standard form you move the decimal point so that there is only one non-zero digit in front of the decimal point.

The Tran family and the Campbell family each used their sprinklers last summer. The water output rate for the Tran family's sprinkler was 35 L per hour. The water output rate for the Campbell family's sprinkler was 25 L per hour. The families used their sprinklers for a combined total of 65 hours, resulting in a total water output of 1925 L. How long was each sprinkler used?

Answers

The time in hours for the Tran family's sprinkler will be 30 hours.

The time in hours for the Campbell family's sprinkler will be 35 hours.

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The water output rate for the Tran family's sprinkler was 35 L per hour.

The water output rate for the Campbell family's sprinkler was 25 L per hour.

And, The families used sprinklers for a combined total of 65 hours, which is resulting in a total water output of 1925 L.

Now,

Let time in hours for the Tran family's sprinkler = t

And, The time in hours for the Campbell family's sprinkler = 65 - t

So, We can formulate by the given condition,

⇒ 35t + 25 (65 - t) = 1925

Solve for t as;

⇒ 35t + 25 (65 - t) = 1925

⇒ 35t + 1625 - 25t = 1925

⇒ 10t + 1625 = 1925

⇒ 10t = 1925 - 1625

⇒ 10t = 300

⇒ t = 30

Thus, The time in hours for the Tran family's sprinkler = t

                                                                                   = 30 hours

And, The time in hours for the Campbell family's sprinkler = 65 - t

                                                                                          = 65 - 30

                                                                                          = 35 hours.

Therefore, we get;

The time in hours for the Tran family's sprinkler will be 30 hours.

The time in hours for the Campbell family's sprinkler will be 35 hours.

given that the probability of a family owning a dog is 0.91, and the probability of a family owning a cat and a dog is 0.15, what is the probability of a family owning a cat given that the family owns a dog?

Answers

The probability of a family owning a cat given that the family owns a dog is 0.164

In probability theory, conditional probability is a measure of the probability of an event occurring, given that another event has already occurred.

Here

probability of a family owning a dog is 0.91,

P(dog) = 0.91

probability of a family owning a cat and a dog is 0.15,

P(dog ∩ cat) = 0.15

according to conditional probability

the probability of occurring of B after event A takes place is

P(A|B)=P(A∩B)/P(A)

so, the probability of a family owning a cat given that the family owns a dog is

        P(dog | cat) =P(dog∩cat)/P(dog)

                            = 0.15/0.91

                            =0.164
