A utility company charges $0. 12 per kilowatt-hour for energy a customer uses. They give a credit of $0. 0025 for every kilowatt-hour of electricity a customer with a solar panel generates that they don't use themselves. A customer has a charge of $82. 04 and a credit of -$4. 10 on this mouth bill. How many kilowatt-hour did they generate that they didn't use themselves?

Answers

Answer 1

The 683.67 kilowatt-hour was charged while 1640 kilowatt-hour generated the credit by not being used.

The amount of electricity consumed will be calculated by the formula -

Amount of electricity consumed = total charged amount ÷ amount of unit electricity consumed

The amount of electricity that earned the credit will be calculated by the formula -

Amount of electricity that earned the credit = total reduction amount ÷ credit on unit electricity

Keep the values in formula

Amount of electricity consumed = 82.04/0.12

Performing division on Right Hand Side of the equation

Amount of electricity consumed = 683.67

Amount of electricity that earned the credit = 4.10/0.0025

Performing division on Right Hand Side of the equation

Amount of electricity that earned the credit = 1640

Thus, the amount of electricity consumed is 683.67 units and unused electricity is 1640 units.

Probability of a call to happen within 6 minutes within each other is 6/60 = 1/10 = 0.1

What is Probability ?

The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, where, broadly speaking, 0 denotes the event's impossibility and 1 denotes certainty.

A statistical function known as a probability distribution explains all the potential values and probabilities for a random variable within a certain range.

The uniform probability distribution is a distribution composed by two bounds, given by a and b, in which each possible outcome within these two bounds is equally as likely.

The probability that a call is made in the first quarter is 15/60

Now the probability of two calls to be made in first quarter = 15/60 * (15/60) = 1/16

A charitable organization in Oxford i hoting a black tie benefit for charity and the organization member hope to bring in at leat $1,200 tandard ticket are available for 21 each wherea vip ticket are offered for 43 a piece

Answers

To reach the goal of $1,200, the organization needs to sell at least 28 standard tickets (1,200 / 42 = 28.57) or 28 VIP tickets (1,200 / 43 = 27.91). They can also combine the sales of standard and VIP tickets to reach the goal.

The charitable organization is hosting a black-tie benefit event and aims to raise at least $1,200 through ticket sales.

The standard tickets are priced at $21 each, while the VIP tickets are priced at $43 each.

To reach the goal of $1,200, the organization needs to sell a minimum of 28 standard tickets ($1,200 / $21 = 57.14).

However, if they only sell VIP tickets, they will need to sell at least 28 VIP tickets ($1,200 / $43 = 27.91).

Finally, they can also achieve their goal by selling a combination of standard and VIP tickets.

For example, they can sell 20 standard tickets and 8 VIP tickets, which would result in a total of 20 * $21 + 8 * $43 = $840 + $344 = $1,184, reaching their goal of $1,200.

In conclusion, the charitable organization has multiple options to reach their goal of $1,200 through ticket sales for their black-tie benefit event.

Answers

After 6 hours, Anderson and Addison will be 126 miles apart.

Let's call the time they have been traveling "t" (in hours).

Anderson will have traveled 15t miles and Addison will have traveled 6t miles. The total distance between them is 15t + 6t = 21t miles.

We know that they need to be 126 miles apart, so we can set up the equation:

21t = 126

Now we can solve for t:

t = 126 / 21

t = 6

So after 6 hours, they both will be 126 miles apart.

Water flows at a speed of 20 cm/s along a rectangular channel into a lake. The width of the channel is 15 cm, the depth of the water is 2.5 cm. Calculate the amount of water that flows from the channel into the lake in 1 hour. Give your answer in litres.

Answers

Answer is 2.7 million liters/hour

What is speed?

Speed tells us how fast something or someone is travelling.

The flow rate of water can be calculated as the cross-sectional area of the channel multiplied by the speed of the water.

The cross-sectional area of the channel can be calculated as width x depth = 15 cm x 2.5 cm = 37.5 cm^2

The flow rate of water can be calculated as 37.5 cm^2 x 20 cm/s = 750 cm^3/s

To convert this to liters, we need to multiply by 1000 to convert cubic centimeters to cubic centimeters:

750 cm^3/s x (1000 cm^3/L) = 750 L/s

Finally, to find the amount of water that flows into the lake in 1 hour, we need to multiply the flow rate by the number of seconds in an hour:

750 L/s x (3600 s/hr) = 2700000 L/hr = 2.7 million liters/hour.

What do you mean by limits?

A limit in mathematics is a value that a function approaches when the input gets closer to a certain value. Limits are used to find a function's derivative and integral as well as to characterize how a function behaves around particular places.

lim x -> c f(x) = L

(a) False.

According to the rules of limits, if both limits are present, the limit of a sum of two functions is equal to the total of their limits. The assertion, however, cannot be valid if one or both of the boundaries do not exist.

(b) False.

According to the limit laws, if the sum of two functions approaches 0, then the sum of their limits also does. The opposite of this statement is untrue, though.

In this instance, even if x approaches 5 and both f(x) and g(x) approach 0, the product of their limits, f(x)g(x), may not exist at all or may approach a non-zero value.

(c) False.

A function's limit as x gets closer to a number from the right is not always the same as the limit as x gets closer to the same number from the left.

Although f(3) = 2 in this instance and lim x3+ f(x) = 2, the limit of f(x) as x approaches 3 from the left may not be 2.

(d) False.

The absence of a limit does not imply the existence of the function's value at that time.

In this instance, the value of h(0) may still exist even though the limit of h(t) as t approaches 0 does not exist.

Using the inscribed angle theorem:

7. m<A = 79°

8. m<B = 90°

9. m(BC) = 152°

What is the Inscribed Angle Theorem?

The Inscribed Angle Theorem states that if two chords of a circle intersect, the measure of the inscribed angle formed by the two chords is equal to half the measure of the central angle that subtends the same arc as the inscribed angle.

Applying the inscribed angle theorem, we have:

7. m<A = 1/2(158)

m<A = 79°

8. m<B = 1/2(180)

m<B = 90°

9. m(BC) = 2(76)

m(BC) = 152°

. use implicit function theorem to verify whether the relation x y 2 cos(x − y) = c defines an implicit solution of the differential equation

Answers

Yes, the relation x y 2 cos(x − y) = c defines an implicit solution of the differential equation.

To verify this we can use Implicit Function Theorem. According to the theorem, if a relation f(x,y) = c is given, then if the partial derivative of f(x,y) concerning y is nonzero at the point (x0,y0), there is a unique function y = g(x) such that f(x,g(x)) = c.

In this case, the partial derivative of f(x,y) concerning y is -2 sin(x-y). At the point (x0,y0), this derivative is nonzero, so there exists a unique function y = g(x) such that f(x,g(x)) = c. This implies that the given relation does indeed define an implicit solution of the differential equation.

In 2015, the per capita consumption of bottled water in the United States was reported to be 36.2 gallons. Assume that the per capita consumption of bottled water in the U.S. is approximately normally-distributed with a standard deviation of 10 gallons.
Find the Z-score of someone who consumed 26.2 gallons of water. Using the Empirical Rule, what is the approximate probability that someone in the United States consumed less than 26.2 gallons of water, what is the approximate probability that someone in the United States consumed between 26.2 and 36.2 gallons of water, and what is the approximate probability that someone in the United States consumed between 26.2 and 46.2 gallons of water?

Answers

The required probabilities = 0.16

The required probabilities = 0.68

What is z-score?

The Z-score quantifies the discrepancy between a given value and the standard deviation. The Z-score, also known as the standard score, indicates how many standard deviations a specific data point deviates from the mean. In essence, standard deviation represents the degree of variability present in a particular data collection.

As given that,

μ = 36.2

σ = 10

As per empirical Rule:

μ± σ = 36.2 ±10 = 26.2, 46.2 = 68%

μ± 2σ = 36.2 ±20 = 16.2, 56.2 = 95%

μ ± 3σ = 36.2 ±30 = 6.2, 66.2 = 99.7%

less than 26.2:

13.5% + 2.35% + 0.15% = 0.16

between 26.2 and 36.2:

68% = 0.68

The required probabilities = 0.16

The required probabilities = 0.68
