What is the bill of a house that consumed 1000 units of electricity,if the first 100 units are charged $10.00 per unit and the remaining units at $5.00 per unit?
Answer:
$14500
Step-by-step explanation:
$10 per unit means 1 unit is equivalent to 10 dollars.
∴Unit multiplier = [tex]\frac{10 dollars}{unit}[/tex]
$5 per unit means 1 unit is equivalent to 5 dollars
∴Unit multiplier = [tex]\frac{5 dollars}{unit}[/tex]
Remaining units = 1000 - 100 = 900 units
The unit multipliers are arranged in such a way that the "units” in the numerator and denominator will cancel each other out leaving us with “dollars” in the numerator. Our answer should be expressed in dollars
since the question requires us to calculate the bill
Bill of the House = Charge of first 100 units + Charge of remaining units
= (1000 units)([tex]\frac{10dollars}{unit}[/tex]) + [(900)units][[tex]\frac{5dollars}{unit}[/tex]]
= $10000 + $4500
= $14500
In the expression 5 a 5 a 5 a 5 a 5 you replace each of the four a symbols with either +, or –, or ×, or ÷. You can insert one or more pairs of parentheses to control the order of

The normal probability plot is a useful tool for assessing the normality of a sample of data. By plotting the sample values against the quantiles of a normal distribution, one can quickly determine whether the data could have come from a population that is normally distributed.
What is sample?Sample data is a subset of data taken from a larger population. It is used to estimate the characteristics of the larger population. Sample data is usually collected using a variety of methods such as surveys, experiments, and simulations. It is important to select a sample that accurately represents the population in order to draw reliable conclusions.
A normal probability plot is a graphical tool used to assess whether or not a sample of data could have come from a population that is normally distributed. The data is plotted on a graph, with the x-axis representing the sample values and the y-axis representing the quantiles of a normal distribution. If the points form a straight line, then the population is normally distributed.
In this situation, the sample data being studied is the wall thickness of O-rings. To create the normal probability plot, each sample value should first be converted to a standard normal deviate, which can be found using the standard normal distribution table. The standard normal deviate is then plotted against the sample values, and the points are connected to form a line. If the line is straight, then it can be concluded that the sample data could have come from a population that is normally distributed. If the line is curved, then the data does not fit the normal distribution.

the cooler with the sports drink to bring to football practice.
B. How many players can fill their water bottles with the sports drink before the cooler is empty? (1 Gallon = 8 pints)
The answer of the question based on the players can fill their water bottles with the sports drink before the cooler is empty is 15 players.
What is Amount?An amount may refer to quantity of something that can be measured, such as amount of substance or amount of the time.
The cooler can hold 5 1/2 gallons of sports drink, and Coach Walker fills 3/4 of it, which means he fills:
5 1/2 gallons * 3/4 = (5 * 2/2 + 1/2) * 3/4 = 15/4 gallons
We know that 1 gallon equals 8 pints, so we can convert the 15/4 gallons to pints:
15/4 gallons * 8 pints/gallon = 30 pints
Therefore, there are 30 pints of sports drink in the cooler. Assuming each player's water bottle can hold 2 pints of sports drink, we can find how many players can fill their bottles before the cooler is empty by dividing the total amount of sports drink by the amount used by each player:
30 pints / 2 pints/player = 15 players
Therefore, 15 players can fill their water bottles with the sports drink before the cooler is empty.

∠M and ∠N are supplementary and m∠M = 37°
. If m∠N = (13x)°
, what is the value of x and the m∠N?
Answer: x = 50, m∠N = 50°
Step-by-step explanation:
x = 50, m∠N = 50°
Since ∠M and ∠N are supplementary, the two angles add up to 180°. Therefore, m∠N = 180° - 37° = 143°. Because m∠N = 13x, we can solve for x by dividing both sides by 13, which gives x = 50. Therefore, m∠N = 13x = 13(50) = 50°.
two are supplementary. the measure of one of these angles is 12 degrees less than one-third the measure of the other.what is the measure of each angle
Answer:
two are supplementary. the measure of one of these angles is 12 degrees less than one-third the measure of the other.what is the measure of each angle
Let's call the measures of the two angles x and y, where x is the larger angle. We know that the two angles are supplementary, which means they add up to 180 degrees:
x + y = 180
We also know that one of the angles (let's say y) is 12 degrees less than one-third the measure of the other angle (x):
y = (1/3)x - 12
Now we can substitute the second equation into the first equation to solve for x:
x + (1/3)x - 12 = 180
Multiplying both sides by 3 to get rid of the fraction, we have:
3x + x - 36 = 540
Combining like terms, we get:
4x - 36 = 540
Adding 36 to both sides, we get:
4x = 576
Dividing both sides by 4, we get:
x = 144
Now we can use the first equation to solve for y:
144 + y = 180
Subtracting 144 from both sides, we get:
y = 36
Therefore, the measures of the two angles are 144 degrees and 36 degrees.

Which statement describes whether the extreme value theorem applies? The extreme value theorem applies, and f(x) has both a minimum and a maximum. The extreme value theorem applies, and f(x) has a maximum but not a minimum. The extreme value theorem does not apply, and f(x) does not have a minimum or a maximum. The extreme value theorem does not apply, and f(x) has a maximum but not a minimum.
The correct answer is "The extreme value theorem applies, and f(x) has both a minimum and a maximum."
What is the extreme value theorem?
The extreme value theorem states that if a function is continuous on a closed interval, then it must have both a maximum and a minimum value on that interval. To determine whether the extreme value theorem applies to the graph of f(x), we need to check if the function is continuous on a closed interval and whether it has a highest and lowest point within that interval.
Looking at the graph of f(x), we can see that the function is continuous on the closed interval [-3, 3] since it has no breaks or jumps. Additionally, the graph has the highest point at (1, 2) and the lowest point at (-3,-2). Therefore, we can conclude that the extreme value theorem applies and that f(x) has both a minimum and a maximum value on the interval [-3, 3].
Therefore, the correct answer is (a) "The extreme value theorem applies, and f(x) has both a minimum and a maximum."

Proportional refers to a linear relationship between two numbers or variables in mathematics. When the first quantity doubles, the second quantity doubles as well. When one of the variables decreases to 1/100th of its previous value, the other falls as well. When two quantities are proportional, it means that as one rises, the other rises as well, and the ratio between the two remains constant at all levels. The diameter and circumference of a circle serve as an example.

Assume that adults have IQ scores that are normally distributed with a mean of μ=105 and a standard deviation σ=20. Find the probability that a randomly selected adult has an IQ between 93 and 117.
The probability that a randomly selected adult has an IQ between 93 and 117 is approximately 0.6827 or 68.27%.
What is probability?
Probability is a branch of mathematics that deals with the study of random events and their outcomes. It is the measure of the likelihood of an event occurring, expressed as a number between 0 and 1.
To find the probability that a randomly selected adult has an IQ between 93 and 117, we need to standardize the distribution using the z-score formula, and then find the area under the normal distribution curve between those two z-scores.
The z-score formula is:
z = (x - μ) / σ
where x is the IQ score we are interested in, μ is the mean IQ score, and σ is the standard deviation of IQ scores.
For the lower bound of 93, the z-score is:
z = (93 - 105) / 20 = -0.6
For the upper bound of 117, the z-score is:
z = (117 - 105) / 20 = 0.6
Now, we need to find the area under the normal distribution curve between these two z-scores. We can use a standard normal distribution table or a calculator to find this probability. Using a calculator, we can use the normalcdf function:
normalcdf(-0.6, 0.6, 0, 1)
This gives us a probability of 0.6827.
Therefore, the probability that a randomly selected adult has an IQ between 93 and 117 is approximately 0.6827 or 68.27%.

3x-y=2, Y=2x-1 substitude for y
Answer:
x = 3
y = 7
Step-by-step explanation:
3x - y = 2 Y = 2x - 1
3x - 2x - 1 = 2
x - 1 = 2
x = 3
Now put 3 in for x and solve for y
3(3) - y = 2
9 - y = 2
- y = -7
y = 7
Let's check
3(3) - 7 = 2
9 - 7 = 2
2 =2
So, x = 3 and y = 7 is the correct answer.
