The bearing of point Q from point P is 80 degrees.
To find the bearing of point Q from point P, we need to determine the angle between the bearing of point P from the common point N and the bearing of point Q from the common point N.
Given that point P is on a bearing of 300 degrees from the common point N, and point Q is on a bearing of 20 degrees from the common point N, we can find the bearing of Q from P as follows:
Calculate the angle between the bearing of P from N and the bearing of Q from N:
Angle = Bearing of Q from N - Bearing of P from N
Angle = 20 degrees - 300 degrees
Angle = -280 degrees
Adjust the angle to be within the range of 0 to 360 degrees:
Since the angle is negative, we can add 360 degrees to it to bring it within the range of 0 to 360 degrees:
Adjusted Angle = -280 degrees + 360 degrees
Adjusted Angle = 80 degrees
Therefore, the bearing of point Q from point P is 80 degrees.

Maria’s vegetable garden measures 5⅔ feet by 6⅚ feet. What is the area of the garden?
Maria’s vegetable garden measures 5⅔ feet by 6⅚ feet. 38.72 feet² is the area of the garden. This can be solved using the concept of the area of rectangle.
What is area of a rectangle?A rectangle is a sort of quadrilateral with parallel sides that are equal to one another and four vertices that are all 90 degrees apart. Because of this, it is also known as an equiangular quadrilateral. Because the opposing sides of a rectangle are equal and parallel, it can also be referred to as a parallelogram.
Each and every square is a rectangle since it is a quadrilateral with right angles on all four sides. But not all rectangles are squares; for a shape to be a square, all of its sides must have the same length.
So a square is also a rectangle and a rhombus. There is no square shape in the rectangle or rhombus. The trapezium shape is a parallelogram.
Maria’s vegetable garden measures 5⅔ feet by 6⅚ feet.
So, it is a rectangular garden.
Now, area = 5⅔ feet × 6⅚ feet
or, area = 17/3 feet × 41/6 feet
or, area = 697 /18 feet²
or, area = 38.72 feet²

Five people (Aaron , Byron , Carina , Duncan , and Evelyn ) form a club, Nequals {A, B, C, D, E}. Carina and Evelyn are women, and the others are men. If they choose a treasurer randomly, find the odds in favor of Evelyn becoming treasurer . The odds in favor of Evelyn becoming treasurer are
================================================
Explanation:
When we talk about "odds in favor", we will use a colon to separate two whole numbers. The first number represents the number of ways for Evelyn to be chosen treasurer (just one way) and the second number represents all the ways she doesn't get chosen (the four other people)
Put another way, writing "odds in favor are 1:4" basically means "there's 1 way to get Evelyn elected and 4 ways for her to not get elected"
Instead of writing 1:4 you could write "1 to 4"
-----------
Side note: Contrast this with "odds against" and the ratio would flip from 1:4 to 4:1. Same idea, but the number of failures is listed first because we're focusing on the "against" (instead of "favor") portion. We read "4:1" as "4 to 1".
The odds in favor of Evelyn becoming treasurer are 1:5 or 1/5.
To determine the odds in favor of Evelyn becoming treasurer, we need to know the total number of possible outcomes and the number of favorable outcomes.
There are five members in the club, so there are five possible outcomes for the treasurer position, one for each member. Since Evelyn is one of the five members, she has one favorable outcome.
Therefore, the odds in favor of Evelyn becoming treasurer are 1:5 or 1/5.

graph h(x)=(x-1)^2-9
The graph of h(x) = (x-1)^2 - 9 is a U-shaped parabola that opens upwards, with the vertex at (1, -9), and it extends indefinitely in both directions.
The function h(x) = (x-1)^2 - 9 represents a quadratic equation. Let's analyze the different components of the equation to understand the behavior of the graph.
The term (x-1)^2 represents a quadratic term. It indicates that the graph will have a parabolic shape. The coefficient in front of the quadratic term (1) implies that the parabola opens upwards.
The constant term -9 shifts the graph downward by 9 units. This means the vertex of the parabola will be at the point (1, -9).
Based on this information, we can draw the following conclusions:
The graph will be a U-shaped curve with the vertex at (1, -9).
The vertex represents the minimum point of the parabola since it opens upward.
The parabola will be symmetric with respect to the vertical line x = 1 since the coefficient of the quadratic term is positive.
The graph will extend indefinitely in both directions.
To accurately plot the graph, you can choose several x-values, substitute them into the equation to find the corresponding y-values, and then plot the points on the graph. Alternatively, you can use graphing software or calculators that can plot the graph of the equation for you.
Remember to label the axes and indicate the vertex at (1, -9) to provide a complete representation of the graph of h(x) = (x-1)^2 - 9.

b. Passes through the point (2, -4) and is parallel to 3x + y = 5
c. Passes through the point (2, -4) and is perpendicular to 3x + y = 5
keeping in mind that parallel lines have exactly the same slope, let's check for the slope of the equation above
\(3x+y=5\implies y=\stackrel{\stackrel{m}{\downarrow }}{-3}x+5\qquad \impliedby \qquad \begin{array}{|c|ll} \cline{1-1} slope-intercept~form\\ \cline{1-1} \\ y=\underset{y-intercept}{\stackrel{slope\qquad }{\stackrel{\downarrow }{m}x+\underset{\uparrow }{b}}} \\\\ \cline{1-1} \end{array}\)
so we're really looking for the equation of a line that has a slope oif -3 and it passes through (2 , -4)
\((\stackrel{x_1}{2}~,~\stackrel{y_1}{-4})\hspace{10em} \stackrel{slope}{m} ~=~ - 3 \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{(-4)}=\stackrel{m}{- 3}(x-\stackrel{x_1}{2}) \implies y +4 = - 3 ( x -2) \\\\\\ y+4=-3x+6\implies {\Large \begin{array}{llll} y=-3x+2 \end{array}}\)
now, keeping in mind that perpendicular lines have negative reciprocal slopes

In two-innings cricket, our team scored 64 runs and then 78 runs. What was our average (mean) for each of the innings?
The average (mean) score for each of the innings is 64 runs for the first inning and 78 runs for the second inning.
To find the average (mean) score for each of the innings in two-innings cricket, we need to calculate the total runs scored in each inning and divide it by the number of innings played.
Given:
First inning score = 64 runs
Second inning score = 78 runs
To find the average for each inning, we divide the total runs by the number of innings played.
For the first inning:
Average score = First inning score / Number of innings
Average score = 64 runs / 1 inning
Average score = 64 runs
For the second inning:
Average score = Second inning score / Number of innings
Average score = 78 runs / 1 inning
Average score = 78 runs
It's worth noting that in two-innings cricket, the average score is calculated separately for each inning, as the total runs and the number of innings are considered independently for each inning.

If 30% of all commuters ride to work in carpools, find the probability that if eight workers are selected, three will ride in carpools.
The probability that out of 8 workers, 3 will ride in carpools is 0.254.
What is probability?
The mathematical concept of probability is used to determine the likelihood of an event. It is solely useful for calculating the probability that an event will occur. From 0 to 1, where 0 represents impossibility and 1 represents a particular occurrence.
We are given that 30% of all commuters ride to work in carpools.
Now, if eight workers are selected, then the probability that three will ride in carpools is determined by using the following
P (X = 3) = \(n C_{x} p^{x} (1-p)^{(n-x)}\)
We have n = 8, x = 3 and p = 0.3
So, using the formula, we get
⇒P (X = 3) = \(8 C_{3} (0.3)^{3} (1-0.3)^{(8-3)}\)
⇒P (X = 3) = \(8 C_{3} (0.3)^{3} (0.7)^{(5)}\)
⇒P (X = 3) = 56 * \((0.3)^{3} (0.7)^{(5)}\)
⇒P (X = 3) = 56 * 0.027 * 0.16807
⇒P (X = 3) = 0.254
Hence, the probability that out of 8 workers, 3 will ride in carpools is 0.254.

To find the second quartile, we must first divide the data in half. There are an even number of data values, so the 50th percentile, or median, is the arithmetic mean of the two values in the middle of the set. Thus, the median is the mean of the 13th data value,
83 and the 14th data value, 86
83+86/2=84.5
Therefore, the second quartile is 84.5
Step 2 of 3 : Find the first quartile.
Considering the given stem-and-leaf plot, the quartiles are given as follows:
The first quartile is of 67.5.The second quartile, which is the median, is of 84.5.The third quartile is of 91.5.What are the median and the quartiles of a data-set?The median of the data-set separates the bottom half from the upper half, that is, it is the 50th percentile.The first quartile is the median of the first half of the data-set.The third quartile is the median of the second half of the data-set.There is an even number of elements(26), hence the median is the mean of the 13th and 14th elements, which are 83 and 86, hence:
Me = (83 + 86)/2 = 84.5.
The first half has 12 elements, hence the first quartile is the mean of the 6th and 7th elements, which are 67 and 68, hence:
Q1 = (67 + 68)/2 = 67.5.
The third half also has 12 elements, starting at the second 86, hence the third quartile is the mean of the 6th and 7th elements of this half, hence:

Answer:

Step-by-step explanation:
I'm assuming the 100 at the end of the question is a typo.
In 2040, the son's age can be written as \(\frac{x}{3}\), where x equals the age of his father. In 2050, the son's age can be written as \(\frac{x-10}{2}\) (as ten years is added between 2040 and 2050). When equated to each other--> \(\frac{x-10}{2}\) = \(\frac{x}{3}\), we can first simplify by multiplying both sides to reach the least common denomination 6, giving us 3(x-10)=2x --->3x-30=2x--->x=30 is the dad's age. The son's age in 2040, 30/3, is equal to 10 years, meaning he was born in the year 2030 (a).
