You reach into a bag of coins and withdraw two coins without replacement. What is the probability you withdrew a nickel and then a dime if the bag held five pennies, ten nickels, and four dimes?

Answers

20/171

aaaaaaaaaaaaaaaaaaaaaa

Answer: [tex]\dfrac{20}{171}[/tex]

Step-by-step explanation:

Given : Number of nickels in the bag = 10

Number of dimes in the bag = 4

The total number of coins in the bag =[tex]10+4+5=19[/tex]

The probability of drawing nickel :-

[tex]\text{P(nickel)}=\dfrac{10}{19}[/tex]

Total number coins left = 18

The conditional probability of drawing dime, given that a nickel is already drawn :-

[tex]\text{P(dime}|\text{nickel)}=\dfrac{4}{18}[/tex]

Now, the probability you withdrew a nickel and then a dime is given by :-

[tex]\text{P(dime and nickel)}=\text{P(dime}|\text{nickel)}\times\text{P(nickel)}\\\\=\dfrac{10}{19}\times\dfrac{4}{18}=\dfrac{20}{171}[/tex]

Now, the probability you withdrew a nickel and then a dime [tex]}=\dfrac{20}{171}[/tex]

This trip covers approximately 1,500 miles. You plan to return the car with a full tank of gasoline. You are considering two options advertised by Hertz: Toyota Camry, 33 mpg highway, costs $465.59 plus taxes and fees totaling $553.28. Toyota Prius Hybrid, 48 mpg highway, costs $634.49 plus taxes and fees totaling $804.61. In both cases, you must purchase gasoline, which costs approximately $3.80 per gallon in California.

Answers

This answer assumes that the majority of the 1,500 miles are on the highway. After adding up the total cost for the trip for each car, the Toyota Camry is the better value. Toyota Camry: Base Price: $553.28 Gas Price: $172.72 Total Price: $726.01 Toyota Prius: Base Price: $804.61 Gas Price: $118,75 Total Price: $923.36 Therefore, based on the distance traveled on this trip, the Toyota Camry is the better value. A longer trip would likely turn the Prius into the better value but not for a 1,500 mile trip.

Parallel slope of 8x+y=11

Answers

Find the parallel slope of 8x + y = 11

First, we must put this into slope-intercept form, just so that we see this better :)

Slope-intercept form : y=mx+b where m=slope, b=y-intercept.

Subtract 8x from both sides.

y = -8x + 11

-8 is in the "m" spot. Remember, m=slope :)

So, our slope is -8.

Remember, if 2 lines are parallel to one another, then they have the same slope.

So, the parallel slope of -8 is -8.

However, if 2 lines are perpendicular from one another, they have negative reciprocal slopes :)

~Hope I helped!~

Answer:

The slope parallel to this line is -8.

Step-by-step explanation:

That's because parallel lines have the same slope. Therefore to find the slope of a parallel line, we must first find the slope of this one. On order to do that, we need to solve for y and then look at the coefficient of x.

8x + y = 11

y = -8x + 11

Therefore, we know the slope to be -8, which means the parallel slope must also be -8.

Write the equation that satisfies the given conditions. The line passes through the two points (3, -1) and (-2, 5). Choices A. 5y = 6x - 23 B. y=-6/5x +13/5 C. y = 4x - 13

Answers

(3,-1)(-2,5)
slope = (5 - (-1) / (-2 - 3) = -6/5

y = mx + b
slope(m) = -6/5
(3,-1)...x = 3 and y = -1
sub and find b, the y int
-1 = -6/5(3) + b
-1 = -18/5 + b
-1 + 18/5 = b
-5/5 + 18/5 = b
13/5 = b

so ur equation is : y = -6/5x + 13/5

Final answer:

To find the linear equation of a line passing through two given points, use the formula for the slope of a line to calculate the slope, then substitute this value, along with one of the given points, into the point-slope form of a line and solve for y.

Explanation:

The subject of this question is the formulation of a linear equation, specifically a equation of a line passing through two given points (3, -1) and (-2, 5). The formula used to find the slope (m) of a line between two points is: m = (y2 - y1) / (x2 - x1). Use this formula to calculate the slope using these points(m = (5 - (-1)) / (-2 - 3) = -6/5) .

Next, using the point-slope form of a line, y - y1 = m(x - x1), we substitute m with the calculated slope, and (x1, y1) with one of the given points. (Let's use (3, -1), y - (-1) = -6/5(x - 3) simplifying this gives us the answer: y=-6/5x +13/5. Therefore, the correct answer is choice B: y=-6/5x +13/5.

Bob can do a job in 5 hours while Bill can do the same job in 8. How many hours would it take them, working together, to do this job?

Answers

Final answer:

Bob and Bill can complete the job together in approximately 3.08 hours by combining their individual rates of work, which are 1/5 and 1/8 jobs per hour respectively.

Explanation:

The question asks how long it would take Bob and Bill to complete a job if they worked together, with Bob being able to do it in 5 hours and Bill in 8 hours. To solve this, we calculate the rates at which Bob and Bill work and then combine these rates to find their combined rate.

Bob's rate is 1 job per 5 hours, or 1/5 jobs per hour. Bill's rate is 1 job per 8 hours, or 1/8 jobs per hour. When they work together, their combined rate is 1/5 + 1/8 = 8/40 + 5/40 = 13/40 jobs per hour.

To find the total time it takes for them to complete 1 job, we take the reciprocal of their combined rate: 1 / (13/40) = 40/13, which is approximately 3.08 hours.

Combining Bob and Bill's individual rates, it would take them approximately 3.08 hours to complete the job together.

Find out how long it would take Bob and Bill to do the job together:

Calculate individual rates.

Bob's rate: He can complete the job in 5 hours, meaning his rate is 1 job / 5 hours.

Bill's rate: He can complete the job in 8 hours, meaning his rate is 1 job / 8 hours.

Combine rates.

To find their combined rate, we simply add their individual rates: Combined rate = Bob's rate + Bill's rate Combined rate = (1 job / 5 hours) + (1 job / 8 hours)

Calculate combined time.

Now, divide 1 (representing the entire job) by the combined rate to find the total time they take working together: Time together = 1 / Combined rate Time together = 1 / ((1 job / 5 hours) + (1 job / 8 hours))

Simplify and express the answer.

This can be simplified to: Time together = 40 / 13 hours Time together ≈ 3.08 hours

Therefore, it would take Bob and Bill approximately 3.08 hours to complete the job together.

The second error is the reasoning in step 5. Instead of "symmetric property" it should be "subtraction property of equality".

The third error is all of line 7. We are not multiplying both sides by 6. Instead we divide both sides by 6. The reasoning should be "division property of equality"

Finally, the last error is the first column on line 8. The final answer should be x = 7 (since 42 divided by 6 = 7)

1.) 7x + 2y = 4
y = -4x + 1

2.) 3x - 4y = 1
-2x + 3y = 1

Answers

1.) The second equation is already solved for y, so this system can be solved with substitution.

7x + 2y = 4
y = -4x + 1

Substitute what y is equal to from the second equation into y of the first equation.

7x + 2(-4x + 1) = 4

7x - 8x + 2 = 4

-x + 2 = 4

-x = 2

x = -2

Now substitute x with -2 in the second original equation to find y.

y = -4x + 1

y = -4(-2) + 1

y = 8 + 1

y = 9

Solution: (-2, 9)

2.) The first equation has 3x. The second equation has -2x. Multiply the first equation by 2 and the second equation by 3 and add them to use the elimination method.

3x - 4y = 1
-2x + 3y = 1

6x - 8y = 2
-6x + 9y = 3
-----------------
y = 5

The first original equation has -4y, and the second original equation has 3y. Multiply the first equation by 3 and teh second by 4 and add them to eliminate y.

9x - 12y = 3
-8x + 12y = 4

x = 7

A right triangle has a hypotenuse of 13 cm and one leg that measures 12 cm. what is the length of the other leg?

Answers

The answer is 22.62

Hope this helps :)

The length of the other leg is 5 cm.

To find the length of the other leg of the right triangle, we can use the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.

Let's denote the length of the other leg as ( x ) cm.

According to the Pythagorean theorem:

[tex]\[ \text{hypotenuse}^2 = \text{leg}_1^2 + \text{leg}_2^2 \][/tex]

Given that the hypotenuse ( c ) is 13 cm, and one leg ( a ) is 12 cm:

[tex]\[ 13^2 = 12^2 + x^2 \][/tex]

[tex]\[ 169 = 144 + x^2 \][/tex]

Now, subtract 144 from both sides:

[tex]\[ x^2 = 169 - 144 \][/tex]

[tex]\[ x^2 = 25 \][/tex]

Taking the square root of both sides:

[tex]\[ x = \sqrt{25} \][/tex]

[tex]\[ x = 5 \][/tex]

Therefore, the length of the other leg is 5 cm.

Explanation:

To calculate the amount of income tax owed, you can use the formula:

Tax amount = Income * Tax rate

Income = $8,425

Tax rate = 15%
