The probability that the friend is between 10 and 30 minutes late is approximately 0.6667, or 66.67%.

Since the probability density function is uniform, the probability of the friend being between 10 and 30 minutes late is equal to the area of the rectangle that lies between x = 10 and x = 30, and below the curve of the probability density function.

The height of the rectangle is equal to the maximum value of the probability density function, which is 1/30 since the interval of possible values for x is [0, 30] minutes.

The width of the rectangle is equal to the difference between the upper and lower limits of the interval, which is 30 - 10 = 20 minutes.

Therefore, the probability of the friend being between 10 and 30 minutes late is:

P(10 < x < 30) = (height of rectangle) x (width of rectangle)

= (1/30) x 20

= 2/3

≈ 0.6667

So the probability that the friend is between 10 and 30 minutes late is approximately 0.6667, or 66.67%.

To rewrite the expression -2(n-7) using the distributive property, we need to distribute the -2 to both terms inside the parentheses. The distributive property states that for any numbers a, b, and c:

a(b + c) = ab + ac

Applying this property to the given expression:

-2(n-7) = -2 * n + (-2) * (-7)

Simplifying further:

-2(n-7) = -2n + 14

Therefore, the rewritten expression is -2n + 14.

On solving the query we can say that The slant height, along with the function cone's height and radius, makes a right triangle as it measures from the apex to a certain point on the circular base.

Mathematics is concerned with numbers and their variations, equations and related structures, shapes and their places, and possible placements for them. The relationship between a collection of inputs, each of which has an associated output, is referred to as a "function". An relationship between inputs and outputs, where each input yields a single, distinct output, is called a function. Each function has a domain and a codomain, often known as a scope. The letter f is frequently used to represent functions (x). X is the input. The four main types of functions that are offered are on functions, one-to-one functions, many-to-one functions, within functions, and on functions.

You are informed that the cone in this scenario has a volume of 4.5 cubic inches. Using the aforementioned calculation, you can determine the radius if you know the cone's height.

Alternately, you may use the Pythagorean theorem to calculate for the radius if you know the cone's slant height. The slant height, along with the cone's height and radius, makes a right triangle as it measures from the apex to a certain point on the circular base.

Answer:

The ratio is 13:9

Step-by-step explanation:

Since the rest of the flowers in the vase are daisies, subtract the 4 roses from the 13 flowers. 13 - 4 = 9

There will be 9 daisies in the vase in total. Then they are asking for you to put the ratio of the total flowers to the daisies.

Total Flower = 13

Daisies = 9

The ratio would be 13 to 9.

The ratio of all flowers in the vase to daises is \(13:9\)

Given the following data:

To determine the ratio of all flowers in the vase to daises:

First of all, we would solve for the number of daisies in the vase of flowers.

\(Number\;of\;daisies = 13-4\)

Number of daisies = 9 daisies.

Now, we can find the ratio of all flowers in the vase to daises:

\(Ratio = F:D\\\\Ratio = 13:9\)

The triangles are similar by the sas similarity theorem.

The similarity theorem for tri angles states that if two triangles have the same shape, then their corresponding angles are equal and their corresponding sides are proportional.

More specifically, if we have two triangles, Triangle ABC and Triangle DEF, such that:

Angle A = Angle D

Angle B = Angle E

Angle C = Angle F

And also, their corresponding sides are proportional:

AB/DE = BC/EF = AC/DF

Then, we can say that Triangle ABC is similar to Triangle DEF. This means that these two triangles have the same shape and they are only different in size.

The similarity theorem is important in geometry, as it allows us to determine unknown side lengths or angle measures of similar triangles by using proportions. It is also useful in real-life situations where we need to determine the size of objects that are not directly measurable

To prove that two triangles are similar using the SAS (Side-Angle-Side) similarity theorem, you need to show that:

Two pairs of corresponding sides are proportional (have the same ratio).

The included angles (the angle between these two pairs of corresponding sides) are congruent.

So, for the SAS similarity theorem to apply, you need to have two triangles where two pairs of corresponding sides are proportional and the included angle between these sides is congruent. If these conditions are met, then the triangles are similar.

The total amount of sugar that was consumed by Kylie in the past nine (9) days is equal to 3 units of sugar.

In Mathematics and Statistics, a line plot refers a type of graph that is used to graphically represent a data set above a number line, while using crosses, dots, or any other mathematical symbol.

Based on the data and information provided in the line plot shown in the image attached above, we can calculate the total amount of sugar that was consumed by Kylie in the past nine (9) days as follows:

Total sugar consumed = (1/8 + 1/8 + 1/8) + 1/4 + (3/8 + 3/8 + 3/8) + (5/8 + 5/8)

Total sugar consumed = 3(1/8) + 1/4 + 3(3/8) + 2(5/8)

Total sugar consumed = 3/8 + 1/4 + 9/8 + 10/8

Total sugar consumed = 22/8 + 1/4

Total sugar consumed = (22 + 2)/8

Total sugar consumed = 24/8

Total sugar consumed = 3 units of sugar.

Answer:  Range is \(y \ge 9\)

Explanation:

The range of \(f(x) = \sqrt{x}\) is  \(y \ge 0\)

In other words, it's the set of nonnegative real numbers.

We only focus on the y values. We go from y to y+9, which means we shift each (x,y) point 9 unit sup.

Since we shifted 9 units up, we add 9 to each y value and that effectively moves the lowest point in the range (0) up nine units.

So we go from \(y \ge 0\) to \(y \ge 9\)

If you need the range in interval notation, then you would write \([9, \infty)\). Note the square bracket next to the 9 so we include this as part of the range.

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.

Answer:

Step-by-step explanation:

3x3=9x3=27

Answer: Hope this helps ;)

Step-by-step explanation:

Let's define the variables as follows:

A = number of hours Alvin worked

S = number of hours Simon worked

T = number of hours Theodore worked

We know that the total number of hours worked is the sum of the number of hours each person worked, so we can write the equation:

A + S + T = 284

We also know that Alvin worked 15 hours more than Simon, so we can write the equation:

A = S + 15

Finally, we know that Theodore worked 6 less than three times as many hours as Simon, so we can write the equation:

T = 3S - 6

We can substitute the second equation into the first equation to eliminate one of the variables:

(S + 15) + S + (3S - 6) = 284

This simplifies to:

5S = 263

Solving for S, we find that Simon worked 52.6 hours.

Substituting this value back into the equation A = S + 15, we find that Alvin worked 67.6 hours.

Finally, substituting the value of S into the equation T = 3S - 6, we find that Theodore worked 156.8 hours.

Therefore, Alvin worked 67.6 hours, Simon worked 52.6 hours, and Theodore worked 156.8 hours.

Answer:

132 square feet

Step-by-step explanation:

The formula for the area of a triangle is 1/2 * b * h. B stands for base and h stands for height. 1/2 multiplied by the base, 10, is 5. We then multiply 5 by 12 which is 60. Let's look at the rectangle now. The area of a rectangle is length by width. The length is 12ft and the width is 6ft. 12 * 6 = 72. 72+60=132 square feet.

Answer:

Step-by-step explanation:

You'd want to separate the two shapes into a rectangle and triangle. So you'd have one rectangle with one side being 2 and the long side 12. (2 * 12 = 24). Then a triangle with a base of 9 and a height of 12. (9 * 12 = 108 / 2 = 54) Then you add both areas together to get 54 + 24 = 78.

Answer:

B: 78

Step-by-step explanation:

cut it in half into a rectangle and traingle

the rectangles area is 2x12=24

The area of the triangle is 9x12=108   108/2 = 54

then add the 2 areas to get B:78

The circumference of the circle is 14π cm.

A circle's circumference is the length of its perimeter. The circumference of a circle can be calculated using length units such as centimeters, meters, or kilometers by opening a circle and measuring the boundary in the same way that we would measure a straight line.

A circle's or an ellipse's circumference is its perimeter. In other words, the circumference would equal the length of the arc if the circle were expanded up and straightened out to a line segment. The perimeter, in a larger sense, is the length of the curve of any closed form.

A circle with radius r encloses an area called πr². Here, the Greek letter stands for the constant proportion of a circle's circumference to its diameter, which is roughly equivalent to 3.14159.
