Answer:
The cost of 27 units of electricity will be Rs. 131.10
Step-by-step explanation:
Given that:
Cost of first 20 units = Rs. 80
Cost of per unit after 20 units = Rs. 7.30
Units consumed in a household = 27 units
Bill of first 20 will be Rs. 80 and 7 units will be charged on the rate of 7.30
Cost of 7 units = 7*7.30 = Rs. 51.10
Cost of 27 units = Rs. 80 + 51.10 = Rs. 131.10
Hence,
The cost of 27 units of electricity will be Rs. 131.10

The line plot, histogram, and box plot provide different visual representations of the reading time data. By analyzing these plots, we can observe the distribution and characteristics of the data, such as central tendency, spread, and outliers.
Line Plot:
A line plot displays data points on a number line, representing the frequency or count of each value.
In this case, the line plot will show the minutes spent reading on the x-axis and the count of students on the y-axis.
For the given data, the line plot will show 10, 20, 30, 40, and 60 on the x-axis, with the corresponding counts displayed above each value.
Histogram:
A histogram displays data distribution by dividing the range of values into intervals or bins and representing the frequency of values falling into each bin.
The histogram will have the minutes spent reading on the x-axis and the count or frequency of students on the y-axis.
The intervals will be 10-19, 20-29, 30-39, 40-49, and 50-59, with the last interval being 60+.
The height of each bar in the histogram will represent the number of students falling into each interval.
Box Plot:
A box plot (also known as a box-and-whisker plot) provides a visual representation of the distribution of data, including measures of central tendency and variability.
The box plot will show a horizontal line inside a box, with whiskers extending from the box, and possibly individual data points beyond the whiskers.
The box will represent the interquartile range (IQR), showing the middle 50% of the data.
The line within the box will represent the median value.
The whiskers will indicate the minimum and maximum values, excluding outliers.
By analyzing these plots, you can observe the central tendency, spread, and distribution of the reading time data. For example, you can identify any outliers, notice the most common reading durations, and observe any patterns or trends within the dataset.

What is the Equivalent expression in standard form: 3x + (2 - 4x)
The number of weaving errors in a twenty-foot by ten-foot roll of carpet has a mean of 0.6. What is the probability of observing less than 4 errors in the carpet? Round your answer to four decimal places.
As per the concept of Poisson distribution, 0.07% is the probability of observing more than 4 errors in the carpet.
Poisson distribution:
According to the Poisson distribution, the probability that X defines the number of successes of a random variable is given by the following formula:
\(P(X=x) =\frac{e^{-\mu}\times\mu^{x}}{x!}\)
Where
x represents the number of successes
e has the value 2.71828 and it is the Euler number
μ is the mean in the given interval.
Given,
The number of weaving errors in a twenty-foot by ten-foot roll of carpet has a mean of 0.6.
Here we need to find the probability of observing less than 4 errors in the carpet and round off it into four decimal places.
Here we only have the mean, we have to use the Poisson distribution.
And we know that, the number of weaving errors in a twenty-foot by ten-foot roll of carpet has a mean of 0.6.
This means that the value of μ = 0.6.
Now, we need to find either we observe 4 or less errors, or we observe more than 4. In both cases, the sum of the probabilities of these outcomes is 1.
So it can be written as,
P(X ≤ 4) + P(X > 4) = 1
Here we want the value of P(X > 4).
It can be written as,
P(X > 4) = 1 - P(X ≤ 4)
We know that, the value of P(X ≤ 4) is calculated as,
P(X ≤ 4) = P(X = 0) + P (X = 1) + P(X = 2) + P(X = 3) + P(X = 4)
When we apply these on the Poisson distribution formula, then we get,
P(X = 0) = (e⁻⁰°⁶ ₓ (0.6)⁰)/0! = 0.5488
P(X = 1) = (e⁻⁰°⁶ ₓ (0.6)¹)/1! = 0.3292
P(X = 2) = (e⁻⁰°⁶ ₓ (0.6)²)/2! = 0.0987
P(X = 3) = (e⁻⁰°⁶ ₓ (0.6)³)/3! = 0.0197
P(X = 4) = (e⁻⁰°⁶ ₓ (0.6)⁴)/4! = 0.0029
Apply the values on the equation, then we get,
P(X ≤ 4) = 0.5488 + 0.3292 + 0.0987 + 0.0197 + 0.0029
P(X ≤ 4) = 0.9993
Therefore, the value of P(X > 4) is,
P(X > 4) = 1 - 0.9993
P(X > 4) = 0.0007
When we convert it into percentage then we get 0.07%
Therefore, 0.07% probability of observing more than 4 errors in the carpet.

Dan Invests £2500 into his bank account. He receives 5% per year simple interest. How much will Dan have after 2 years? Give your answer to the nearest penny where appropriate.
Please help me give me the answer:
Explanation:
Answer:
Sure, I'd be happy to help you with that!
To calculate Dan's earnings with simple interest, we can use the following formula:
I = P * r * t
where:
I = interest earned
P = principal amount (initial investment)
r = interest rate (as a decimal)
t = time period (in years)
We know that Dan invests £2500 and receives 5% simple interest per year, so:
P = £2500
r = 0.05
t = 2 years
Plugging these values into the formula, we get:
I = £2500 * 0.05 * 2
I = £250
This means that Dan will earn £250 in interest over the 2-year period.
To calculate Dan's total earnings, we simply add the interest earned to the initial investment:
Total earnings = £2500 + £250
Total earnings = £2750
Therefore, Dan will have £2750 in his bank account after 2 years.

Consider the two circles shown.
To show that circle P is similar to circle Q, circle P is translated t units to the right. The image is then dilated about its center by a scale factor of s.
What are the values of t and s?
Show me:
(t) What is the horizontal distance between the center of circle P to the center of circle Q?
(s) What is the scale factor dilating from circle P to circle Q?
The similar circles P and Q can be made equal by dilation and translation
The horizontal distance between the center of circles P and Q is 11.70 unitsThe scale factor of dilation from circle P to Q is 2.5The horizontal distance between their centers?From the figure, we have the centers to be:
P = (-5,4)
Q = (6,8)
The distance is then calculated using:
d = √(x2 - x1)^2 + (y2 - y1)^2
So, we have:
d = √(6 + 5)^2 + (8 - 4)^2
Evaluate the sum
d = √137
Evaluate the root
d = 11.70
Hence, the horizontal distance between the center of circles P and Q is 11.70 units
The scale factor of dilation from circle P to QWe have their radius to be:
P = 2
Q = 5
Divide the radius of Q by P to determine the scale factor (k)
k = Q/P
k = 5/2
k = 2.5
Hence, the scale factor of dilation from circle P to Q is 2.5

A bag contains seven yellow marbles and two blue marbles. You randomly select two marbles from the bag. What is the probability that both marbles are yellow when you replace each marble before selecting the next marble? Write your answer as a decimal rounded to the nearest thousandth. Brainliest to best answer
Answer:
0.605--------------------------
The probability of selecting a yellow marble on the first draw is 7/9, since there are 7 yellow marbles out of 9 total marbles.
Since we replace the marble before the second draw, the probability of selecting a yellow marble on the second draw is also 7/9.
To find the probability of both events happening together, we multiply the probabilities:
P(both yellow) = (7/9) x (7/9) = 49/81 = 0.6049382716Rounding to the nearest thousandth, the answer is 0.605.
Triangle ABC with vertices at A(4, 3), B(3, −2), C(−3, 1) is dilated using a scale factor of 1.5 to create triangle A′B′C′. Determine the vertex of point A′.
The vertex of point A' in the dilated triangle A'B'C' is (6, 4.5).
1. Start by calculating the distance between the vertices of the original triangle ABC:
- Distance between A(4, 3) and B(3, -2):
Δx = 3 - 4 = -1
Δy = -2 - 3 = -5
Distance = √((-\(1)^2\) + (-\(5)^2\)) = √26
- Distance between B(3, -2) and C(-3, 1):
Δx = -3 - 3 = -6
Δy = 1 - (-2) = 3
Distance = √((-6)² + 3²) = √45 = 3√5
- Distance between C(-3, 1) and A(4, 3):
Δx = 4 - (-3) = 7
Δy = 3 - 1 = 2
Distance = √(7² + 2²) = √53
2. Apply the scale factor of 1.5 to the distances calculated above:
- Distance between A' and B' = 1.5 * √26
- Distance between B' and C' = 1.5 * 3√5
- Distance between C' and A' = 1.5 * √53
3. Determine the coordinates of A' by using the distance formula and the given coordinates of A(4, 3):
- A' is located Δx units horizontally and Δy units vertically from A.
- Δx = 1.5 * (-1) = -1.5
- Δy = 1.5 * (-5) = -7.5
- Coordinates of A':
x-coordinate: 4 + (-1.5) = 2.5
y-coordinate: 3 + (-7.5) = -4.5
4. Thus, the vertex of point A' in the dilated triangle A'B'C' is (2.5, -4.5).

The triangles ΔABC and ΔADC are congruent triangles by
a) definition of mid-point
b) measure of ∠ACB = measure of ∠ACD = 90°
What are Congruent Triangles?Transformations change the size or position of shapes. Congruent shapes are identical, but may be reflected, rotated or translated. Scale factors can increase or decrease the size of a shape. Congruent Triangles simply mean the triangles that possess the same size and shape
The three sides are equal (SSS: side, side, side)
Two angles are the same and a corresponding side is the same (ASA: angle, side, angle)
Two sides are equal and the angle between the two sides is equal (SAS: side, angle, side)
A right angle, the hypotenuse and a corresponding side are equal (RHS, right angle, hypotenuse, side)
Given data ,
Let the first triangle be represented as ΔABC
Let the second triangle be represented as ΔADC
Now , the side AC is the common bisector of both the triangles such that
C is the midpoint of BD
So , the measure of side BC = measure of side CD
And , the perpendicular bisector is right angle
So , the measure of ∠ACB = measure of ∠ACD = 90°
And , the measure of AC = measure of AC ( reflexive property )
Therefore , the triangles are congruent by SAS theorem
Hence , the triangles are congruent

to pay a "tax" of 2.5 points, but she expects to gain 75 points.
For each quest, how many points can she gain overall?
The number of points gained overall by Julia playing the game is 30 point
How to determine the number of points gained overall?From the question, we have the following parameters that can be used in our computation:
Tax paid for a new quest = 2.5 points
Total points gained playing the game = 75 points

In the last 24 days, it rained 18 days. What is the ratio of rainy days to total days written as a percent?
The ratio of rainy days to total days written as a percent will be 75%.
How to illustrate the ratio?Ratio demonstrates how many times one number can fit into another number. Ratios contrast two numbers by ordinarily dividing them. A/B will be the formula if one is comparing one data point (A) to another data point (B).
Ratio is used to compare two or more numbers. It is also used to indicate how big or small a quantity is when it is compared to another. It should be noted that in a ratio, two quantities are compared using division.
Since in the last 24 days, it rained 18 days.
Number of rainy days = 18.
Number of total days = 24
The ratio of rainy days to total days written as a percent will be:
= Number of rainy days / Total days × 100
= 18/24 × 100
= 3/4 × 100
= 75%
Therefore, the ratio is 3:4 which is 75%.
