To reach her home in half an hour, she needs to double her speed twice, which is equivalent to a 200% increase in speed. Therefore, the correct answer is 200%.

Speed is a measure of how quickly an object or person moves from one point to another. It is usually expressed in terms of distance traveled over time, for example, miles per hour or kilometers per hour.

To calculate this, we need to find the time taken for her to reach her home if her speed is doubled.

If her initial speed is 40 km/hr, then by doubling her speed, she will be travelling at a speed of 80 km/hr.

By travelling at this speed, she can reach her home in half an hour i.e. 30 minutes.

Therefore, the time taken to reach her destination by doubling her speed is 30 minutes.

The time taken to reach her destination while travelling at her initial speed is 2 hours.

To calculate the percentage increase in speed, we have to find the ratio of the time taken to reach her destination when the speed is doubled to the time taken to reach her destination when the speed is not doubled.

Therefore, the percentage increase in speed

= (30/120) x 100

= 25%.

Since she needs to double her speed to reach her home in half an hour, the percentage increase in speed required is 100%.

To reach her home in half an hour, she needs to double her speed twice, which is equivalent to a 200% increase in speed.

Therefore, the correct answer is 200%.

The trapezoid ABCD have the measure of angles m∠A and m∠B equal to 79° and 66° respectively.

The sum of the interior angles of a quadrilateral is equal to 360°, so the sum of angles, m∠A, m∠B, m∠C, and m∠D is equal to 360°.

2x - 19 + x + 17 + 3x + 7 + 2x - 37 = 360°

8x - 32 = 360°

8x = 360° + 32°

8x = 392

x = 392/8 {divide through by 8}

x = 49

m∠A = 2(49) - 19 = 79°

m∠A = 49 + 17 = 66°

Therefore, the trapezoid ABCD have the measure of angles m∠A and m∠B equal to 79° and 66° respectively.

Answer:

The probability that a given user is transmitting is 0.1 = 10%.

The probability that at any given time, exactly n users are transmitting simultaneously is \(P(X = n) = C_{120,n}.(0.1)^{n}.(0.9)^{120-n}\).

0.0048 = 0.48% probability that there are 21 or more users transmitting simultaneously.

Step-by-step explanation:

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

\(P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}\)

In which \(C_{n,x}\) is the number of different combinations of x objects from a set of n elements, given by the following formula.

\(C_{n,x} = \frac{n!}{x!(n-x)!}\)

And p is the probability of X happening.

Can be approximated to a normal distribution, using the expected value and the standard deviation.

The expected value of the binomial distribution is:

\(E(X) = np\)

The standard deviation of the binomial distribution is:

\(\sqrt{V(X)} = \sqrt{np(1-p)}\)

Normal probability distribution

Problems of normally distributed distributions can be solved using the z-score formula.

In a set with mean \(\mu\) and standard deviation \(\sigma\), the zscore of a measure X is given by:

\(Z = \frac{X - \mu}{\sigma}\)

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

When we are approximating a binomial distribution to a normal one, we have that \(\mu = E(X)\), \(\sigma = \sqrt{V(X)}\).

Each user transmits only 10 percent of the time.

This means that \(p = 0.1\)

Find the probability that a given user is transmitting.

The probability that a given user is transmitting is 0.1 = 10%.

Suppose there are 120 users.

This means that \(n = 120\)

Find the probability that at any given time, exactly n users are transmitting simultaneously.

This is \(P(X = n)\).

This n is different from the n of total number of users(120 in this case) from the standard binomial formula. This is the number of successes, which is the equivalent of x. So

\(P(X = n) = C_{120,n}.(0.1)^{n}.(0.9)^{120-n}\)

The probability that at any given time, exactly n users are transmitting simultaneously is \(P(X = n) = C_{120,n}.(0.1)^{n}.(0.9)^{120-n}\)

Find the probability that there are 21 or more users transmitting simultaneously.

Now we use the binomial approximation to the normal. We have that:

\(\mu = E(X) = np = 120*0.1 = 12\)

\(\sigma = \sqrt{V(X)} = \sqrt{np(1-p)} = \sqrt{120*0.1*0.9} = 3.2863\)

Using continuity correction, this probability is \(P(X \geq 21 - 0.5) = P(X \geq 20.5)\), which is 1 subtracted by the pvalue of Z when X = 20.5. So

\(Z = \frac{X - \mu}{\sigma}\)

\(Z = \frac{20.5 - 12}{3.2863}\)

\(Z = 2.59\)

\(Z = 2.59\) has a pvalue of 0.9952

1 - 0.9952 = 0.0048

0.0048 = 0.48% probability that there are 21 or more users transmitting simultaneously.

Answer:

The mean is 36

Step-by-step explanation:

The mean of these numbers is 36.

Part (a)

To verify a point is on the line, we plug the coordinates into that equation. If we get a true result at the end, then we've confirmed the point is on that line.

For point A(-5,0) we have x = -5 and y = 0 pair up together. Let's plug these coordinates into x - 3y = -5 to get the following steps shown below.

x - 3y = -5

-5 - 3(0) = -5

-5 - 0 = -5

-5 = -5

We get a true statement at the end, which confirms x-3y = -5 is true when x = -5 and y = 0. Therefore, point A is definitely on the line x - 3y = -5

Repeat similar steps for B(4,3) to show that this point is also on x - 3y = -5

x - 3y = -5

4 - 3(3) = -5

4 - 9 = -5

-5 = -5

This confirms point B is also on this line.

We have confirmed line AB is x-3y = -5

I'll let you check to see if C(-3,9) and D(1,-3) are on the line 3x+y = 0. The steps will follow the same outline as shown above.

=========================================================

Part (b)

The standard form equation Ax+By = C has the slope m = -A/B, where B cannot be zero.

The equation x-3y = -5 has A = 1 and B = -3 to give us a slope of m = A/B = -1/(-3) = 1/3

Meanwhile the equation 3x+y = 0 gives the slope of A/B = -3/1 = -3

Notice that slopes 1/3 and -3 multiply to -1. This is one useful property of perpendicular lines. Their slopes always multiply to -1; this is assuming neither line is vertical, nor horizontal.

Put another way, the slopes are negative reciprocals of one another. We flip the fraction and flip the sign to go from 1/3 to -3, or vice versa.

I recommend using GeoGebra to plot out the points mentioned, and forming the lines AB and CD. This helps give a quick visual confirmation the lines are perpendicular.

----------

To summarize: We found the slopes of line AB and CD to be 1/3 and -3 respectively. The slopes multiply to -1 which is sufficient to conclude the lines are perpendicular.

=========================================================

Part (c)

We have this system of equations

x - 3y = -5

3x + y = 0

To represent lines AB and CD respectively.

Let's triple everything in line CD to go from 3x+y = 0 to 9x+3y = 0

Therefore, an equivalent system is this

x - 3y = -5

9x + 3y = 0

The first equation hasn't changed. After this point, we can see the y terms add to 0 since -3y+3y = 0y = 0. Therefore, the y terms cancel which lets us solve for x.

10x = -5

x = -5/10

x = -0.5

Then we use this to find y

x-3y = -5

-0.5-3y = -5

-3y = -5+0.5

-3y = -4.5

y = -4.5/(-3)

y = 1.5

The point of intersection is (-0.5, 1.5)

Notes:

-0.5 = -1/2

1.5 = 3/2

=========================================================

Part (d)

The x coordinates of points A and B are -5 and 4 in that order.

Add them up: -5+4 = -1

Divide the result in half: -1/2 = -0.5

This is the x coordinate of the midpoint of segment AB.

Repeat for the y coordinates

Add: 0+3 = 3

Divide in half: 3/2 = 1.5

The midpoint of segment AB is (-0.5, 1.5) which is exactly the result of part (c).

You should find that the midpoint of segment CD is also (-0.5, 1.5)

I'll let you do those steps.

=========================================================

Part (e)

e)  Kite

Step-by-step explanation:

Given endpoints:

Given equations of the lines:

To quickly check that the given equations are correct, input the x-value of a point on the line into the given equation of the line containing that point. If the y-value corresponds with the y-value of the point, the equation is correct.

Using point A to check equation AB:

\(\begin{aligned}x=-5 \implies -5-3y&=-5\\-3y&=0\\y&=0\end{aligned}\)

As point A is (-5, 0), the equation is correct.

Using point C to check equation CD:

\(\begin{aligned}x=-3 \implies 3(-3)+y&=0\\-9+y&=0\\y&=9\end{aligned}\)

As point C is (-3, 9), the equation is correct.

If two lines are perpendicular, their slopes are negative reciprocals.

The negative reciprocal of a number is -1 divided by the number.

Rearrange each equation to slope-intercept form, then compare slopes.

\(\begin{aligned}\textsf{Line}\;AB: \quad x-3y&=-5\\-3y&=-x-5\\3y&=x+5\\y&=\dfrac{1}{3}x+\dfrac{5}{3}\end{aligned}\)

Therefore, the slope of line AB is ¹/₃.

\(\begin{aligned}\textsf{Line}\;CD: \quad 3x + y &= 0\\y&=-3x\end{aligned}\)

Therefore, the slope of line CD is -3.

\(\textsf{As} \;\dfrac{-1}{-3}=\dfrac{1}{3}, \textsf{ the slopes are negative reciprocals}.\)

Hence, the lines are perpendicular.

To find the point of intersection of AB and CD, solve the system of equations.

\(\begin{cases}x - 3y = -5\\3x + y = 0\end{cases}\)

Rearrange the second equation to isolate y:

\(\implies y=-3x\)

Substitute the found expression for y into the first equation and solve for x:

\(\implies x-3(-3x)=-5\)

\(\implies x+9x=-5\)

\(\implies 10x=-5\)

\(\implies x=-\dfrac{5}{10}\)

\(\implies x=-\dfrac{1}{2}\)

Substitute the found value of x into the expression for y and solve for y:

\(\implies y=-3\left(-\dfrac{1}{2}\right)\)

\(\implies y=\dfrac{3}{2}\)

Therefore, the solution to the system of equations is:

\(\left(-\dfrac{1}{2},\dfrac{3}{2}\right)\)

\(\boxed{\begin{minipage}{7.4 cm}\underline{Midpoint between two points}\\\\Midpoint $=\left(\dfrac{x_2+x_1}{2},\dfrac{y_2+y_1}{2}\right)$\\\\\\where $(x_1,y_1)$ and $(x_2,y_2)$ are the endpoints.\\\end{minipage}}\)

\(\begin{aligned}\textsf{Midpoint of $\overline{AB}$}&=\left(\dfrac{x_B+x_A}{2},\dfrac{y_B+y_A}{2}\right)\\&=\left(\dfrac{4+(-5)}{2},\dfrac{3+0}{2}\right)\\&=\left(-\dfrac{1}{2},\dfrac{3}{2}\right)\end{aligned}\)

\(\begin{aligned}\textsf{Midpoint of $\overline{CD}$}&=\left(\dfrac{x_D+x_C}{2},\dfrac{y_D+y_C}{2}\right)\\&=\left(\dfrac{1+(-3)}{2},\dfrac{-3+9}{2}\right)\\&=\left(-1,3\right)\end{aligned}\)

each event (picking a student and checking the ownership of a car) is independent and non-overlapping.

so, the probability that all 5 own a car is the chance of picking the 5th student owning a car AND all 4 previous student picks owning a car.
