A triangular portion of a baseball field is marked as shown below to the nearest 10th what is the length of the side label C
Answers
Answer:
A
Step-by-step explanation:
Here, we are told to calculate the length of the side labeled c.
The best thing to do here is to use sine rule.
Mathematically;
c/sin 28 = 3/sin 36
3sin 28 = c sin 36
c = 3sin 28/sin 36
c = 2.396 which is approximately 2.40 yds

Alex records the running time—the number of minutes a movie lasts from start to finish—of 50 popular movies. The distribution of times, in minutes, is shown in the histogram below. Which of these intervals contains the most movies? 80–90 minutes 90–100 minutes 100–110 minutes 110–120 minutes
Answers
Answer:
Check Explanation
The histogram for the question isn't attached. But from the options provided for this question (80–90 minutes 90–100 minutes 100–110 minutes 110–120 minutes), it is evident that the bars and intervals for the question have the same width. So, the interval with the most movies will be the interval whose bar is the tallest.
Pick the interval whos bar has the highest height.
Step-by-step explanation:
The histogram for this question is missing. I couldnt get the histogram online, so, I will use a random histogram example to explain how to pick the interval with the highest frequency.
A histogram is a chart representation that uses bars to describe numerical data. It divides the entire distribution into Intervals and the number of variables in each interval (the frequency) corresponds to the area of each bar. This is the major difference between a bar chart and a histogram; the bars can be unequal for a histogram unlike that of bar charts.
If the bars are of equal widths, then the frequency of each interval is simply the height of the interval's bar.
In the attached histogram example for this question, the histogram shows the monthly salaries of workers and the frequency of workers receiving whichever salary. The intervals for these salaries for this histograms are in steps of $25. The bars start from $800 to $825, $825 to $850 and so on.
Since all the intervals have the same width, the interval with the most workers receiving the salary in that interval is the $900 to $925 interval with the tallest bar with frequency of 150.
If the bars weren't of the same width, the area of each bar is computed and the bar with the highest area has the highest frequency.
From the options provided for the question asked (80–90 minutes 90–100 minutes 100–110 minutes 110–120 minutes), it is evident that the bars and intervals for the question have the same width. So, the interval with the most movies will be the interval whose bar is the tallest.

A Ferris wheel is 15 meters in diameter and boarded from a platform that is 1 meters above the ground. The six o'clock position on the Ferris wheel is level with the loading platform. The wheel completes 1 full revolution in 2 minutes. How many minutes of the ride are spent higher than 15 meters above the ground?
Answers
Answer:
The number of minutes of the ride that are spent higher than 15 meters above the ground is 18 minutes.
Step-by-step explanation:
We will use the sin function for the height of the Ferris wheel.
[tex]y=A\ sin(B(x+C))+D[/tex]
A = amplitude
C = phase shift
D = Vertical shift
2π/B = period
From the provided information:
A = 15/2 = 7.5 m
[tex]Period=2\\\\\frac{2\pi}{B}=2\\\\B=\pi[/tex]
Compute the Vertical shift as follows:
D = A + Distance of wheel from ground
= 7.5 + 1
= 8.5
The equation of height is:
[tex]h(t)=7.5\cdot sin(\pi (t+C))+8.5[/tex]
Now at t = 0 the height is, h (t) = 1 m.
Compute the value of C as follows:
[tex]h(t)=7.5\cdot sin(\pi (t+C))+8.5[/tex]
[tex]1=7.5\cdot sin(\pi (0+C))+8.5\\\\-7.5=7.5\cdot sin\ \pi C\\\\sin\ \pi C=-1\\\\\pi C=sin^{-1}(-1)\\\\\pi C=\frac{3\pi}{2}\\\\C=\frac{3}{2}[/tex]
So, the complete equation of height is:
[tex]h(t)=7.5\cdot sin(\pi (t+\frac{3}{2}))+8.5[/tex]
Compute the number of minutes of the ride that are spent higher than 15 meters above the ground as follows:
h (t) ≥ 15
[tex]h(t)=15\\\\7.5\cdot sin(\pi (t+\frac{3}{2}))+8.5=15\\\\7.5\cdot sin(\pi (t+\frac{3}{2}))=6.5\\\\sin(\pi (t+\frac{3}{2}))=\frac{6.5}{7.5}\\\\(\pi (t+\frac{3}{2}))=sin^{-1}[\frac{13}{15}]\\\\\pi (t+\frac{3}{2})=60.074\\\\t+\frac{3}{2}=19.122\\\\t=17.622\\\\t\approx 18[/tex]
Thus, the number of minutes of the ride that are spent higher than 15 meters above the ground is 18 minutes.

1. What is the lateral surface area of a solid 8 meters high
whose base is the figure at right? Dimensions are in meters.
2. Which inequality corresponds to the graph at right?
Answers
Answer:
Step-by-step explanation:
To calculate the lateral surface of this shape we must divide it into 3 parts :
Part 1 : the half cylinder with the radius r=15We must calculate its perimeter P1 :
P1 = (15*2)*π/2 = 30*π*(1/2)=15π
Part 2 : the half cylinder with the radius r=12-5=7We must calculate its perimeter P2:
P2= (7*2)*π/2=14*π*(1/2)= 7π
Part 3 : the cubeWe won't calculate its perimeter because it has some common sides with the cylinders .
Let P3 be the perimeter of what's remaining from the cube
P3=12+5= 17
Now the total perimeter : Pt
Pt= 15π+7π+17= 22π+17
The lateral surface : Ls
Ls= (22π+29)*8= 784.92 m²

Answers
Choice A: [tex]2,2, \sqrt{4}[/tex]
Choice B: 9, 40, 41
Choice C: [tex]\sqrt{5}, 10$ and \sqrt{125}[/tex]
Answer:
(B)9, 40, 41
Step-by-step explanation:
To check if the sides form a right triangle, you check to see if they satisfy the Pythagorean theorem.
[tex]Hypotenuse^2=Opposite^2+Adjacent^2[/tex]
Note that the longest side length is always the hypotenuse.
Choice A: [tex]2,2, \sqrt{4}[/tex]
Now, [tex]\sqrt{4}=2[/tex]
Therefore:
[tex]2^2\neq 2^2+2^2\\4 \neq 8[/tex]
These side lengths form an equilateral triangle. They do not satisfy the theorem.
Choice B: 9, 40, 41
The longest side length is 41.
[tex]41^2=1681[/tex]
[tex]40^2+9^2=1681[/tex]
Therefore:
[tex]41^2=40^2+9^2[/tex]
These side lengths form a right triangle.
Choice C: [tex]\sqrt{5}, 10$ and \sqrt{125}[/tex]
[tex]\sqrt{5} \approx 2.24 \\ \sqrt{125}\approx11.18[/tex]
Therefore, the longest side length is [tex]\sqrt{125}[/tex]
[tex](\sqrt{125})^2=125\\(\sqrt{5})^2+10^2=5+100=105\\\\(\sqrt{125})^2 \neq (\sqrt{5})^2+10^2[/tex]
These side lengths do not form a right triangle.
The total cost of an office dinner was shared equally by k of the n employees who attended the dinner. What was the total cost of the dinner? (1) Each of the k employees who shared the cost of the dinner paid $19. (2) If the total cost of the dinner had been shared equally by k + 1 of the n employees who attended the dinner, each of the k + 1 employees would have paid $18.
Answers
Answer:
$342
Step-by-step explanation:
Let the total cost of the dinner = C
If it was shared equally by k employees who attended the dinner and each of the k employees who shared the cost of the dinner paid $19.
We have:
[tex]\dfrac{C}{k}=19 \\\\C=19k[/tex]
If the total cost(C) had been shared equally by k + 1 employees who attended the dinner, each of the k + 1 employees would have paid $18.
This written mathematically is:
[tex]\dfrac{C}{k+1}=18 \\\\C=18(k+1)[/tex]
Equating the cost, C from both equations
19k=18(k+1)
19k=18k+18
19k-18k=18
k=18
Therefore, the total cost of the dinner,
C=19k
=19 X 18
=$342

Question number 2 : Rihannon gets a new bedspread that is 33 inches longer. What LENGTH of fringe does Rihannon need for the longer bedspread??? PLEASEEE HELP
Answers
Answer:
1) To calculate length of fringe, we need to find the perimeter
The question does not clearly say how much is length and width
Assuming length = 245 and width = 234 inches
P = 2(length + width)
P = 2 ( 245 + 234)
P = 2 (479)
P = 958 inches
2) To calculate length of fringe, when length is increased by 33 inches
P = 2 ( l + w)
P = 2 (278 + 234)
P = 2 x 512
P = 1024 inches

This is a question on geometric distribution.
In geometric distribution, we have two possible outcomes for each trial (success or failure) for independent number of binomials series trial. Also the probability of success is constant for each trial.
This discrete probability distribution is represented by the probability density function: f(x) = p× (1-p)^(x-1)
For a random variable with a geometric distribution, we do not know the number of trials we will have = {1, 2, 3, ...}
We stop the trials when we get a success.
From the question, there are 10 numbers
The probability of success = p = 1/10
For the solutions of the question from (a-e), See attachment below.
f(x) = P(X= x)
Where P(X= x) is the probability of X taking on a value x
