The senior class of a high school needs to decide where to go for their senior trip. They have four choices: A cruise, a camping trip, a snorkeling trip, or to the Great Wall of China. Due to budget constraints they cannot survey all 800 people in the senior class so they randomly select 150 people from the class and ask them their preference. The table shows the results. Using the sample results, estimate the proportion of the entire population that would like to go camping in the Tetons.Using the sample results, estimate the proportion of the entire population that would like to go camping in the Tetons.

P(-5, 2), Q(4, 5), R(6, – 1), S(-3, -4)
this is a rectangle right and why is it and not rhombus or square?
Answer:
It's a rectangle, but not a rhombus (or square).
Step-by-step explanation:
Let's see the vectors of each next vertex:
[tex]Q - P = (4, 5) - (-5, 2) = (9, 3)\\R - Q = (6, -1) - (4, 5) = (2, -6)\\S - R = (-3, -4) - (6, -1) = (-9, -3)\\P - S = (-5, 2) - (-3, -4) = (-2, 6)\\[/tex]
Firstly, we can notice that it's a parallelogram - because the Q-P side is parallel to the S - R side (if the x:y ratios are the same, the sides are parallel).
A rhombus needs the sides to be of the same length. But the length of a (x, y) vector is [tex]\sqrt{x^2 + y^2}[/tex] and [tex]\sqrt{9^2 + 3^2} > \sqrt{2^2 + (-6)^2}[/tex], we don't even have to compute it exactly. If it's not a rhombus, it's also not a square (every square is a rhombus).
The last thing left is to know if it's a rectangle - for it to be a rectangle, we need to check if the vectors are perpendicular.
We can compute the dot product of the vectors - perpendicular vectors always have a dot product equal to zero. The dot product of two vectors [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] is equal to [tex]x_1x_2 + y_1y_2[/tex].
[tex](9, 3) \cdot (2, -6) = 9\cdot 2 + 3\cdot(-6) = 18 - 18 = 0[/tex]
So the sides are perpendicular, and as such - the figure is a rectangle.

Answer:
1) -3a + 24b
2) 5x^2 + 2x +1
Step-by-step explanation:
1) (-a + -a+ -a) + (6b + 8b + 10b)
(-3a) + (24b)
-3a + 24b
2) (2x^2 + 3x^2) + (4x - 2x) + (7-6)

The circumference of a circular field is 191.54 yards. What is the radius of the field? Use 3.14 for Pi and do not round your answer.
Answer:
C = 2πr
191.64 = 2 × 3.14 × r
r = 191.64/6.28
r = 30.51 yds
What is the sum of the interior angles of the polygon pictured below?
Answer:
360°
explanation:
the sum of interior angles of all quadrilaterals (polygons with four sides) is 360°. If you put a pen at any of the four corners and try to draw a line to any other corner, you'll find you can only make two triangles. And since the angle sum of triangles is 180°, 180 times 2 = 360
Use what you've learned to write the equation of a parabola that is narrower than y = x ,
2
opens downward, and has vertex (2, – 4).
Answer:
y = -a(x – 2)² – 4
a > 1
Example:
y = -2(x – 2)² – 4
Step-by-step explanation:
y = a(x – h)² + k
____________________
vetex: (h, k)
a: vertical reflection or stretch/compression
__________________________________
If it opens downward, has a vertex of (2, -4) and is narrower than y = x².
Then x² will have a negative coefficient of less than -1 and the input of x will be subtracted by the x value of the vertex which is 2, and the output will be added by the y value of the vertex which is -4.
Therefore y = -a(x – 2)² – 4 where a > 1
-What could be concluded if the relative frequency of an event is equal to 0?
Answer: If the frequency is 0, it does not repeat.
Step-by-step explanation: A relative frequency table is a chart that shows the popularity or mode of a certain type of data based on the population sampled. When we look at relative frequency, we are looking at the number of times a specific event occurs compared to the total number of events.

Answer: The Answer is 11.
Step-by-step explanation: You line up the least to the greatest so in this case, 8, 6 , 10 , 13 , 14 , and 15, and than you divide that amount by however many numbers there are you are working with. Which would be 6. When all divided and done, it is all equal to 11

Dave owns 1/4 of a business. Delta owns 1/5 and Alice owns 1/2. The banks owns the rest. Who owns the smallest portion on the business? What fraction of the business does the bank own?
Answer: bank owns smallest portion 1/20
Step-by-step explanation: Dave 1/4= 0.25 = 25 %. Delta 1/5 = 0.20 = 20%
And Alice 1/2 = 0.5 =50%. Bank owns 5% = 5/100 = 1/20

You are a first year police officer in Swanton, Ohio.
You are earning a monthly
salary of $4718.
Next year you will be given a raise to $62147 annually.
How much more per month will you earn your second year?
Answer:
$460.92
Step-by-step explanation:
First year monthly salary = $4,718
Second year annual salary = $62,147
Second year monthly salary = Annual salary / 12
= $62,147 / 12
= $5,178.92
How much more per month will you earn your second year?
Amount of increase in second year monthly salary = Second year monthly salary - First year monthly salary
= $5,178.92 - $4,718
= $460.92
