Answer:

1/8 ÷ 4/1 = 1/32

Answer:

-50 (Hopefully I gave the right answer. If I didn't, I'm sorry)

step-by-step explanation:

ABD= 2x-3 and DBE= 3x+8

2x-3=3x+8

Add 3 to both sides.

2x=3x+11

Now subtract 3x from both sides

-1x=11

Now divide both sides by -1

x=-11

Plug -11 in for x

2(-11)-3 and 3(-11)+8

-22-3 and -33+8

-25 and -25

-25+-25=-50

Step-by-step explanation:

Look at the blue triangle. Start at point C and count the number of unit you move on the blue in the x-axis direction (2).

Now from that point move up on the blue triangle in the y-axis direction (1).

The slope =  (rise)/run which is (the movement on y)(the movement on X)

       Slope = 1/2

The slope of the line CD in the given diagram is 1/2.

If a line between two points (x₁, y₁) and (x₂, y₂), then the slope of the line will be \(m = \frac{(y_{2} - y_{1})}{(x_{2}-x_{1})}\)

Given points A, B, C, D are colinear.

As these points are mentioned on the graph, we can take the coordinate any point as reference and then calculate the other point easily from the graph.

Here, the slope of any part of the line AD will be equal.

Let, the coordinate of point C is (x, y).

Therefore, as per the diagram, the coordinate of the point D is

\((x + 2, y + 1)\).

Now, the slope of the line CD is(m)

\(= \frac{y+1 - y}{x+2-x} = \frac{1}{2}\)

By using the equation for the perimeter, we will see that the width is 11 inches and the length 8 inches.

The frame is a rectangle. Remember that for a rectangle of length L and width W, the perimeter is:

P = 2*(W + L)

In this case we know that the perimeter is 38 inches, and the length is 3 inches shorter than the width, then we can write two equations:

38in = 2*(W + L)

L = W - 3in

Replacing the second equation in the first one we get:

38in = 2*(W + W - 3in)

38in = 4*W - 6in

38in + 6in = 4*W

44in = 4*W

44in/4 = W

11in = W

The width is 11 inches, and the length is 11in - 3in = 8 in.

In the given stem-and-leaf plot, we can conclude that there are at least 5 outliers

The number of outliers in the given stem-and-leaf plot can be determined by identifying values that are significantly higher or lower than the majority of the data.

To find the number of outliers in the stem-and-leaf plot, we need to analyze the data distribution and identify values that deviate significantly from the rest of the scores.

Looking at the stem-and-leaf plot, we observe that the majority of the scores are concentrated between 20 and 90. The numbers 2, 3, 4, 5, 6, 7, 8, 9, and 10 represent the tens digit of the scores, while the leaves represent the ones digit.

Upon examining the plot, we notice that there are a few values that stand out from the rest. These values are 00, 01677, 6899, 233569999, and 01268. Outliers are typically defined as values that fall outside the "typical" range of the data, and these values appear to deviate significantly from the majority of the scores.

To determine the exact number of outliers, we need to apply specific criteria. One common method is to use the 1.5 × IQR (interquartile range) rule. The IQR is calculated as the difference between the third quartile (Q3) and the first quartile (Q1) of the data. Any values below Q1 - 1.5 × IQR or above Q3 + 1.5 × IQR are considered outliers.

In this case, we don't have the exact raw data to calculate the quartiles and IQR. However, based on visual inspection of the stem-and-leaf plot, we can still identify the values mentioned earlier as outliers due to their significant deviation from the majority of the scores.

Therefore, in the given stem-and-leaf plot, we can conclude that there are at least 5 outliers

The question is incomplete:

Donovan spent $5.75 at the fruit stand. He bought 3 apples and 2 oranges. He spent the rest of the money on bananas. The image with the price per fruit is attached. How many bananas did Donovan buy?

A. 1 banana

B. 2 bananas

C. 3 bananas

D. 4 bananas

Answer:

D. 4 bananas

Step-by-step explanation:

First, you have to consider that the total amount paid is equal to adding up the results of multiplying the price for each fruit for the number of fruits purchased which would be:

Total cost=(3*0.75)+(2*1.25)+0.25x, x is the number of bananas

Total cost=2.25+2.5+0.25x

Now, you can replace the total cost with 5.75 that is the amount Donovan spent and solve for x:

5.75=2.25+2.5+0.25x

5.75-2.25-2.5=0.25x

1=0.25x

x=1/0.25

According to this, the answer is that Donovan bought 4 bananas.

When the significant figures are being calculated, the last digit of the result is always uncertain. If there are no remaining digits, it is significant. When multiplication or division is performed, the calculation's outcome is limited to the number of significant figures present in the number with the fewest significant figures.

To know how many significant figures are in the following calculation, (2.461 × 4.215) - 5.122, we need to follow the following steps;2.461 × 4.215 = 10.386915 (multiply first)10.386915 - 5.122 = 5.264915 (subtract next)To determine the final number of significant figures in the result, use the number with the least significant figures. So, 5.122 has the least number of significant figures, which is four (4), so the result is limited to four (4) significant figures. Therefore, the number of significant figures is four (4).This calculation has three (3) significant figures that are reliable. The trailing zeros to the right of the decimal place do not provide any additional information. So, the answer is:There are four (4) significant figures resulting from the given calculation.

Answer:

P = 37.4 m

Step-by-step explanation:

let the third side of the triangle be x

using Pythagoras' identity in the right triangle.

x² + 7² = 16²

x² + 49 = 256 ( subtract 49 from both sides )

x² = 207 ( take square root of both sides )

x = \(\sqrt{207}\) ≈ 14.4 m ( to 1 decimal place )

the perimeter (P) is then the sum of the 3 sides

P = 7 + 16 + 14.4 = 37.4 m

The graph of y = 3x + 1 lies in quadrants I and III. The graph of the equation y = 3x + 1 is a straight line with a positive slope.

To determine the quadrants in which the graph lies, we need to analyze the signs of the x and y coordinates in different regions of the coordinate plane.

Quadrant I: In this quadrant, both the x and y coordinates are positive. When we substitute positive values for x into the equation, we obtain positive values for y. Since the slope is positive, the line rises as we move from left to right. Therefore, the graph lies in quadrant I, where both x and y are positive.

Quadrant III: In this quadrant, the x coordinate is negative, while the y coordinate is positive. If we substitute negative values for x into the equation, we still obtain positive values for y. The positive slope ensures that the line rises from right to left. Hence, the graph also lies in quadrant III.

The graph does not pass through quadrants II and IV because the signs of the coordinates do not align with the equation. In quadrant II, the x coordinate is negative, but the y coordinate is negative as well. In quadrant IV, both the x and y coordinates are positive, which contradicts the equation. Therefore, the graph of y = 3x + 1 is confined to quadrants I and III.

As, stx = tsx for every eigenvector x of t, and eigenvectors corresponding to distinct eigenvalues are linearly independent, we can conclude that st = ts.

To prove that st = ts, where v is finite-dimensional, t and s are linear operators on v, t has dim v distinct eigenvalues, and s has the same eigenvectors as t (not necessarily with the same eigenvalues), we can use the fact that eigenvectors corresponding to distinct eigenvalues are linearly independent.

Let's consider an eigenvector x of t with eigenvalue λ. We can write this as tx = λx. Now, since s has the same eigenvectors as t, we can write this as sx = λx.

Now, let's consider the product stx. Using the definitions of s and t, we have stx = s(λx) = λ(sx).

Since sx = λx, we can substitute this in the above equation to get stx = λ(λx) = λ²x.

On the other hand, let's consider the product tsx. Using the definitions of s and t, we have tsx = t(λx) = λ(tx).

Since tx = λx, we can substitute this in the above equation to get tsx = λ(λx) = λ²x.

Since stx = tsx for every eigenvector x of t, and eigenvectors corresponding to distinct eigenvalues are linearly independent, we can conclude that st = ts.

The mean number of observations per unit time is approximately 8.5.

The mean number of observations per unit time can be calculated using the Poisson distribution formula, which is:

P(X = k) = (e^-λ * λ^k) / k!

where λ is the mean number of occurrences per unit time.

If we know that p(8)-p(9), it means that we have the following probability:

P(X = 8) - P(X = 9) = (e^-λ * λ^8) / 8! - (e^-λ * λ^9) / 9!

We can simplify this expression by multiplying both sides by 9!:

9!(P(X = 8) - P(X = 9)) = (9! * e^-λ * λ^8) / 8! - (9! * e^-λ * λ^9) / 9!

Simplifying further:

9!(P(X = 8) - P(X = 9)) = λ^8 * e^-λ * 9 - λ^9 * e^-λ

We can solve for λ by trial and error or by using numerical methods such as Newton-Raphson. Using trial and error, we can start with a value of λ = 8 and check if the left-hand side of the equation equals the right-hand side:

9!(P(X = 8) - P(X = 9)) = 8^8 * e^-8 * 9 - 8^9 * e^-8 ≈ 0.00062

This is a very small number, so we can try a higher value of λ, such as 9:

9!(P(X = 8) - P(X = 9)) = 9^8 * e^-9 * 9 - 9^9 * e^-9 ≈ -0.00011

This is closer to zero, so we can try a value between 8 and 9, such as 8.5:

9!(P(X = 8) - P(X = 9)) = 8.5^8 * e^-8.5 * 9 - 8.5^9 * e^-8.5 ≈ 0.00026

This is even closer to zero, so we can conclude that the mean number of observations per unit time is approximately 8.5.

Step-by-step explanation:

First stop of Caroline = At 36 mile marker

Destination of Caroline = At 353 mile marker

Distance left to be covered = 353 - 36 = 317 miles

Given that Caroline decides to stop at an attraction \(\frac{3}{4}\) of the way after she stops for gas.

i.e. at a distance \(\frac{3}{4}\) of 317 miles away from the Gas stop.

\(\frac{3}{4} \times 317 = 79.25\times 3 \approx 238\ miles\)

So, Caroline stops at a point which is around 238 miles away from the gas station.

To calculate the Mile marker of her stop, we need to add the mile marker of gas station and the distance of her stop from gas station.

Mile marker location at her stop = 36+238 = 274

The bank statement  that is shown in the question shows a loss of £285.00 and calculated by subtracting the total expenses (money out) from the total revenue (money in).

Profit or loss is a measure of the financial performance of a business, organization, or individual over a given period of time.

Profit refers to the positive difference between the revenue earned by a business or individual and the expenses incurred during a given period.

A loss occurs when the expenses incurred exceed the revenue earned during a given period.

To calculate the profit or loss, you need to subtract the total expenses (money out) from the total revenue (money in).

In this case, the total revenue is £315.00 + £265.00 + £190.00 = £770.00, and the total expenses are £210.00 + £30.00 + £450.00 + £100.00 = £790.00.
