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

Answer 1
20/171







aaaaaaaaaaaaaaaaaaaaaa
Answer 2

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]

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.

In which of these cases is each stamp worth the most?
1. 7 of the same stamp worth a total of $3.15
2. 8 of the same stamp worth a total of $3.20
3. 10 of the same stamp worth a total of $4.10
4. 16 of the same stamp worth a total of $4.80

Answers

3.15 /7 = 0.45

3.20/8 = 0.40

4.10/10 = 0.41

4.80/16 = 0.3


Answer is 1. 7 stamps worth 3.15

Answer:

1. 7 stamps for $3.15 → $0.45/stamp

Step-by-step explanation:

Calculate the price per stamp for each scenario:

1)[tex]\frac{3.15}{7}=0.45[/tex]/stamp

2)[tex]\frac{3.20}{8}=0.40[/tex]/stamp

3)[tex]\frac{4.10}{10}=0.41[/tex]/stamp

4)[tex]\frac{4.80}{16}=0.3[/tex]/stamp

Therefore the first scenario of stamps will be the worth the most per stamp, as it has a higher cost than the rest.

Answers

Problem 1)

Check out the attached image "figure 1". The graph of the line is shown in red. The red line is the equation y = -3x+4. The answer choices A through D are shown as blue points. Only point A = (1,7) is not on the red line. So point A is not a solution to the equation.

Answer: Choice A) (1,7)

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

Problem 2)

First error is in step 3, specifically the "additive inverse" portion. It should be "additive property of equality" since we're adding 10x to both sides.

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)

See the image attachment "figure 2" for the visual summary of the table, and what needs to be fixed.

Answers

When graphed, a function and its inverse function become symmetrical across the line y = x.  

What is a symmetrical function?

A function that is symmetric is a function whose variables remain constant regardless of the ways in which the variables are permutated.

Hence When graphed, a function and its inverse function become symmetrical across the line y = x.

Step-by-step explanation:

The given expression is [tex]\frac{(5-3x)}{5}[/tex]

We solve it further to get the simplified form.

[tex]\frac{(5-3x)}{5}[/tex] = [tex]\frac{5}{5}-\frac{3x}{5}[/tex]

What ten times 13 divided by 130, how you solve it

Answers

10 multiplied by 13 is 130. A trick is to just take the zero away and multiply 13 times 1, and then after you do this you add the zero back on. 130 divided by 130 is 1. You can do the same kind of trick for this, just when you are done, you do not add the zeros back in.
10 x 13 = 130 
You can find this by adding 10, 13 times 

Looking like this: 10+10+10+10+10+10+10+10+10+10+10+10+10= 130 

Or, another simpler way would be to multiply 1 x 13 = 13 and then add the number of 0's that are in the equation, which there is only one, so we then get 130!

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.

My company charges 10 cents per minute over 5 minutes when using Internet at its store. It also charges a 5 dollar fee for usage. How many minutes can I get with 10 dollars?

Answers

so if you use it for less than 5 minutes is more than likely free.

now, you start downloading the macarena song and other mp3s, and it takes longer then they charge 10 cents or $0.10  per minute after those 5 minutes.

so, if you use it 

6 mins   you pay 1 * 0.10
7 mins   you pay 2 * 0.10
8 mins   you pay 3 * 0.10
9 mins   you pay 4 * 0.10
10 mins   you pay 5 * 0.10

x mins   you pay (x - 5) * 0.10   so long "x" is 5 or higher.

now, they charge a $5 fee, that's just a connection fee, so is charged only once,

so the cost function will be

[tex]\bf \stackrel{cost}{y}=\stackrel{\textit{connection fee}}{5}+\stackrel{\textit{over 5 mins fee}}{(x-5)0.10} \\\\\\ \textit{how much can you get for 10 bucks? well if 10 bucks is the \underline{cost}} \\\\\\ 10=5+(x-5)0.1\implies 5=0.1(x-5)\implies \cfrac{5}{0.1}=x-5 \\\\\\ 50=x-5\implies \stackrel{minutes}{55}=x[/tex]
