April wants to know what the probability is that a card drawn randomly from a deck will be a heart. Her sample space includes all 52 cards in a standard deck. Which of these outcomes composes the event?

(This question was not multiple choice)

Answers

Answer 1
52 / 4 (types of cards): 13.

13/52.

13 is prime. 52 can be divided by 13.

1/4 chance that a card will be hearts, or a 25% chance.
Answer 2

There is a 1/4 chance.

In decimal 0.25

In percentage 25%

Can you help me list the following stocks and bonds in order from highest default risk to lowest default risk?
-A municipal bond in a city with a population of 150,000
-A common stock in a company under federal investigation
-A preferred stock in a 150-year old firm with good business practices

Answers

Final answer:

From highest to lowest default risk, the investments would likely be ranked as follows: common stock in a company under federal investigation, a municipal bond from a relatively small city, and preferred stock in a stable, long-established firm.

Explanation:

The default risk of a financial investment is the likelihood that the issuer of the instrument will be unable to meet their obligations, thereby causing a default. From the highest to lowest default risk, the list would likely be:

Common stock in a company currently under federal investigation: This company has the highest default risk because the investigation could lead to penalties, disruptions in its business, or damage to its reputation.A municipal bond from a city with a population of 150,000: Though generally considered safe, these bonds can still go into default. The default risk here is lower than the stock under investigation because municipal bonds are backed by the taxes and revenue of the municipality, making them more stable than corporations which are dependent on their business performance.A preferred stock in a 150-year old firm with good business practices: This has the lowest default risk. Preferred stocks have a lower risk than common stocks because they receive dividends before common stock and have a higher claim on the assets in case of bankruptcy. The age of the firm and its good business practices also suggest stability and reduced risk.

A businessman has 10 employees; his salary is equal to 6 times the average of employees' salary. If the 11 of them received a total of 64000 in a one year, what was the businessman's salary that year?

Answers

Let [tex]x[/tex] be the average salary of an employee. Since the salary of the business man is 6 times the average salary of an employee, his salary will be [tex]6x[/tex]. We also know that the sum of the salary of the businessman and the average salaries of his 10 employees is 640000, so:
[tex]6x+10x=64000[/tex]
Solving for [tex]x[/tex]:
[tex]16x=64000[/tex]
[tex]x= \frac{64000}{16} [/tex]
[tex]x=4000[/tex]
The average salary of an employee is 4000, so the salary of the businessman will be [tex]6*4000=24000[/tex].

We can conclude that the business man's salary that year was 24000.

vic is driving 450 miles to his grandma's house. if vic can drive 25 miles per gallon of gas,how many gallons if gas will he use round trip

Answers

In order to find the answer to this question, you need to multiply 450 by 2 to find the amount of miles in the round trip, which is 900.

Next, you divide 900 by 25, because that will leave you with the amount of gas it needs. 

So the answer is 36.


P.S. I don't know if 450 miles is round trip or it is half. But if it is half, the answer would be 18

(9r-5)-(-4r+9)

Answers

The first step for solving this expression is to remove the first set of parenthesis.
9r - 5 - (-4 + 9)
In order to find the sum inside the parenthesis we must keep the sign of the number with the larger absolute value and subtract the smaller absolute value from the larger. This will look like the following:
+ (9 - 4)
Now subtract the numbers and add it back into the expression.
9r - 5 - 5
Now we will calculate the difference between -5 - 5 and add it back into the expression.
9r - 10
Since we cannot simplify this any further,, 9r - 10 is going to be the correct answer to your question.

Answers

The answer is 9.
This is because if you buy 10 pencils, it will cost a total of three dollars. 0.30 times 10=3.00. You then subtract this amount by 7.50, getting 4.50. 4.50 is the total amount that was spent on pens, but since you are trying to figure out how many pens were bought, you divide 4.50 by the cost of one pen (0.50).
This gives you 9.

Hi there!

In order to solve, you can use substitution. This means that you use one equation and solve for one variable, then use that one equation and plug it into the other equation. Here's how we'd do it:

WORK:
x = 12 - y (since x is already solved for, we'll use that to plug into the other given equation.
2(12 - y) + 3y = 29 (using substitution)
24 - 2y + 3y = 29
24 + y = 29
y = 5
Plug the value of y back into the first equation
x = 12 - 5
x = 7

A - x = 7, y = 5

Kimela’s little sister likes to swing the playground. Yesterday, Kimela pulled the swing back and let it go. The swing traveled a distance of 9 feet before heading back the other way. Each swing afterward was only 70% as long as the previous one. Find the total distance the swing traveled.

Answers

it went 6.3 feet every other swing cause 70% of 9 is 6.3

To find the total distance traveled by the swing, we use the sum of an infinite geometric series formula with the first swing distance being 9 feet and a common ratio of 0.7. The sum equals 30 feet, indicating the total distance the swing traveled.

The question involves finding the total distance traveled by a swing that starts with an initial swing length and then decreases by a certain percentage with each subsequent swing. It can be classified as a series problem in mathematics, specifically dealing with a geometric series.

First swing distance is 9 feet. Each subsequent swing is only 70% of the previous, which means the ratio is 0.7. We want to find the sum of this geometric series. The total distance traveled by the swing is the sum of the distances traveled in each direction, so the swing's distances form an infinite series. To find the total distance traveled, we use the formula for the sum of an infinite geometric series:

S = [tex]\frac{a}{1-r}[/tex]

where S is the sum of the series, a is the first term, and r is the common ratio (in this case, 0.7). Plugging in the values, we get:

S = [tex]\frac{9 feet }{(1 - 0.7)}[/tex] = 9 feet ÷ 0.3 = 30 feet

Hence, the total distance traveled by the swing is 30 feet.

The answer is A.

When setting up a proportion, it doesn't really matter which numbers go where, as long as you are consistent.

A is the correct answer because it is set up as width/length = width/length. So when you solve for the missing length, you are finding what value of x will make 9/x the same ratio as 10/12.

The height of a ball in feet is modeled by
[tex]y = - 16x {}^{2} + 72x[/tex]
where X is the time in seconds after the ball is hit. How long is the ball in the air?

(May I also get steps on how to solve these kind of questions please?)

Answers

The answer to this question is 4.5 seconds. You can see from the graph that the ball is above the ground in the interval 0 < t < 4.5. It is at t = 4.5 where the graph touches the t-axis. When it touches the t-axis, then the height is 0 and therefore on the ground.

The value of time of the ball in the air is,

⇒ 4.5 seconds

What is Quadratic equation?

An algebraic equation with the second degree of the variable is called an Quadratic equation.

We have to given that;

The height of a ball in feet is modeled by the equation,

y = - 16x² + 72x

where, x is the time in seconds after the ball is hit.

Hence, For time of the ball in the air, we can plug y = 0 in above equation.

y = - 16x² + 72x

0 = - 16x² + 72x

Solve for x;

- 16x² + 72x = 0

- 4x (4x - 18) = 0

This gives,

4x = 18

x = 18/4

x = 4.5 seconds

Thus, The value of time of the ball in the air is,

⇒ 4.5 seconds

Write an equation in standard form for the line whose slope is undefined and and passes through (-6,4).

A line whose slope is undefined has no finite slope; the line is a vertical one.
A vertical line has an equation of the form x = k.  In this case, since the line passes thru (-6,4), the eq'n of the line is x = -6.

The equation represents a vertical line passing through the point (-6, 4) is x= -6.

When the slope is undefined, it means that the line is vertical.

In this case, the line passes through the point (-6, 4).

A vertical line has the equation of the form x = k, where k is a constant. Since the line passes through (-6, 4), the equation of the line in standard form is:
