Step-by-step explanation:

The probability that a banana is picked for the first one is:

1/10

because there are 10 fruits and one of them is a banana,

Then, the second piece has to be a pear.

For this we have already picked one fruit out of the bag, which leaves 9 fruits in the bag.

There are 4 pears so the probability of picking a pear second is

4/9

To find the probability of a banana and then a pear, you want to multiply these values together

So:

1/10 x 4/9 = 4/90 = 2/45

Sheri walked approximately 1 mile to school and 1 mile to the library, for a total distance of approximately 2 miles.

What is distance?

In physics and mathematics, distance refers to the length or amount of space between two points or objects. It is a scalar quantity, which means that it has magnitude but no direction.

To estimate how far Sheri walked in total, we can round the distances she walked to the nearest half-mile, which will give us an approximate answer.

Distance can be measured using various units such as meters, kilometers, miles, feet, or yards, depending on the context and the precision required. For example, the distance between two cities may be measured in kilometers or miles, while the distance between two points on a map may be measured in centimeters or inches.

It is important to distinguish between distance and displacement. While distance refers to the total length of the path traveled by an object, displacement refers to the distance between the initial and final positions of the object, regardless of the path taken.

Rounding 15/16 to the nearest half-mile gives us 1 mile (since 15/16 is closer to 1 than to 1.5).

Rounding 7/8 to the nearest half-mile gives us 1 mile (since 7/8 is closer to 1 than to 0.5).

So, Sheri walked approximately 1 mile to school and 1 mile to the library, for a total distance of approximately 2 miles. Note that this is an estimate, and the actual distance she walked may be slightly more or less than 2 miles.

Answer:

Step-by-step explanation:

Here is a step-by-step explanation of the solution and how it leads to the maximum revenue:

Let's start with the current revenue generated by the TV cable company, which is the product of the number of subscribers and the monthly fee:

Current revenue = Number of subscribers * Monthly fee

Current revenue = 6400 * $28

Current revenue = $179,200

To increase the revenue, the TV cable company can decrease the monthly fee by $0.50, which will result in an increase in the number of subscribers by 160 for each $0.50 decrease. Let's calculate the additional revenue generated by each $0.50 decrease in the monthly fee:

Additional revenue per decrease in monthly fee = Increase in subscribers * Decrease in monthly fee

Additional revenue per decrease in monthly fee = 160 * $0.50

Additional revenue per decrease in monthly fee = $80

The TV cable company can continue to decrease the monthly fee by $0.50 until the revenue stops increasing. Let's calculate the number of $0.50 decreases in monthly fee required to reach the maximum revenue:

Number of $0.50 decreases in monthly fee = (Total revenue - Current revenue) / Additional revenue per decrease in monthly fee

Number of $0.50 decreases in monthly fee = ($20,000,000 - $179,200) / $80

Number of $0.50 decreases in monthly fee = 248,525

The corresponding decrease in monthly fee is:

Decrease in monthly fee = Number of $0.50 decreases in monthly fee * Decrease in monthly fee

Decrease in monthly fee = 248,525 * $0.50

Decrease in monthly fee = $124,262.50

The corresponding increase in subscribers is:

Increase in subscribers = Number of $0.50 decreases in monthly fee * Increase in subscribers

Increase in subscribers = 248,525 * 160

Increase in subscribers = 39,764,000

The total number of subscribers at the maximum revenue point is:

Total subscribers = 6400 + Increase in subscribers

Total subscribers = 6400 + 39,764,000

Total subscribers = 39,770,400

The monthly fee at the maximum revenue point is:

Monthly fee = Current revenue / Total subscribers

Monthly fee = $179,200 / 39,770,400

Monthly fee = $0.0045

The maximum revenue is:

Maximum revenue = Total subscribers * Monthly fee

Maximum revenue = 39,770,400 * $0.0045

Maximum revenue = $178,966.80

Therefore, the TV cable company can generate maximum revenue of $178,966.80 per month by decreasing the monthly fee by $0.50 for each 160 additional subscribers.

Let's use the variable 'x' to represent the number of 30c cards and the variable 'y' to represent the number of 35c cards.

If the total price of the box is $5.80, we can write the equation:

If the number of 30c cards is six more than half the number of 35c cards, we have that:

Using this value of x in the first equation, we have:

So the number of 35 cards is 8.

Answer:

a) C) The system has no solutions only when h=3 and k is any real number.

b) D) The system has a unique solution when \(h=(-\infty,3)U(3,\infty)\) and k is any real number.

c) The system has may solutions when h=3 and k=15

Step-by-step explanation:

a) In order to determine when the system will have no solution, we can start by solving the equation by substitution. We can solve the first equation for x1:

\(x_{1}+hx_{2}=3\)

so

\(x_{1}=3-hx_{2}\)

Next we can substitute this into the second equation so we get:

\(5(3-hx_{2})+15x_{2}=k\)

We distribute the 5 into the first parenthesis so we get:

\(15-5hx_{2}+15x_{2}=k\)

and group like terms:

\(-5hx_{2}+15x_{2}=k-15\)

we factor x2 so we get:

\(x_{2}(-5h+15)=k-15\)

and solve for x2:

\(x_{2}=\frac{k-15}{-5h+15}\)

this final answer is important because it tells us what value the system of equations is not valid for. That answer will not ve vallid if the denominator is zero, so we can set the denominator equal to zero and solve for h, so we get:

\(-5h+15= 0\)

and solve for h:

\(-5h= -15\)

\(h=\frac{-15}{-5}\)

\(h= 3\)

so it doesn't really matter what value k gets since all that matters is that the denominator of the answer isn't zero.

b)

For part b we need to know when the system of equations will have infinitely many answers. Generally, this will happen when both equations are basically the same, so we need to make sure to simplify the second equation so it looks like the first equation, compare them and determine the respective coefficients.

So we take the second equation and factor it:

\(5x_{1}+15x_{2}=k\)

we start by factoring a 5 from the left side of the equation so we get:

\(5(x_{1}+3x_{2})=k\)

Next, we divide both sides of the equation into 5 so we get:

\(x_{1}+3x_{2}=\frac{k}{5}\)

we now compare it to the first equation:

\(x_{1}+hx_{2}=3\)

\(x_{1}+3x_{2}=\frac{k}{5}\)

In this case, every coefficient of the two equations must be the same for us to get infinitely many answers, so we can see that h=3 and \(\frac{k}{5}=3\)

when taking the second condition and solving for k we get that:

\(k=3(5)\)

so

k=15

Anything else than the specific combination h=3 and k=15 will give us unique solutions, so for b, the answer is:

D) The system has a unique solution when and k is any real number.

c)

We have already solved part c on the previous part of the problem, so the answer is:

The system has many solutions when h=3 and k=15

the correct answer must be option C, which has the coordinates (5, -7), matching the centroid of the data points. Thus, the line of best fit passes through the point (5, -7).

How to find the coordinates?

To determine which point the line of best fit passes through, we need to use the fact that the line passes through the centroid of the data points. The centroid is the point (mean of x-coordinates, mean of y-coordinates).

Given that the mean of the x-coordinates is 5 and the mean of the y-coordinates is -7, the centroid is (5, -7). Therefore, we need to look for the point among the given options that has coordinates (5, -7).

The point (5, -7) is not listed as an option, but we can find the point that is closest to it.

Option A (-7,5) has the coordinates switched, so it cannot be the correct answer. Option B (7-5) is not a valid point since it is missing a comma between the x and y coordinates. Option D (-5,7) has the correct x-coordinate but the wrong y-coordinate.

Therefore, the correct answer must be option C, which has the coordinates (5, -7), matching the centroid of the data points. Thus, the line of best fit passes through the point (5, -7).
