If the angles are represented in degrees, find both angles sin(x+76)=cos(3x+2)
Step-by-step explanation:
[tex]x + 76 + 3x + 2 = 90[/tex]
[tex]4x + 78 = 90[/tex]
[tex]4x = 12[/tex]
[tex]x = 3[/tex]
Angle 1 is 79
Angle 2 is 11.
What is the mean absolute deviation of the following data set
Answer:
4.32
Step-by-step explanation:
First, we have to find the mean of the data set.
16, 11, 9, 12, 11, 10, 10, 8, 15, 0, 2, 15, 14, 7, 11, 5, 14, 20, 3, 11, 13, 7, 0, 5, 21 all added together equals 250. 250 divided by 25 = 10. So 10 is the mean.
Now we have to find the absolute distances of each number from the mean.
16 - 10 = 6... 11 - 10 = 1... so on, giving us this -->
6, 1, 1, 2, 1, 0, 0, 2, 5, 10, 8, 5, 4, 3, 1, 5, 4, 10, 7, 1, 3, 3, 10, 5, 11
Finally, we have to find the mean of the distances (which is done by adding all the numbers above and dividing the sum by the number of values there are).
108 divided by 25 = 4.32.
So, 4.32 is the mean absolute deviation (MAD) of the following data set.

First, you need to come up with an activity. If you are having trouble thinking of what to do, here are some ideas:
How many jumping jacks can you do in a minute?
How many times can you write your full address in a minute?
How many points can you score in a game in 3 minutes?
How many pages of a book can you read in 4 minutes?
How far can you walk in 5 minutes?
Feel free to be creative or even to come up with an activity you think your teacher has not seen before.
Now that you have decided what your activity is going to be, it’s time to get started.
Part 1: Record Information
Spend a short amount of time (one to five minutes) doing your activity. Answer the following questions:
What was the activity?
How long did you spend doing your activity?
How much of the activity did you complete in the time period? (Example: I did 24 sit-ups in one minute).
Which of these variables is your dependent variable?
Which one is the independent variable?
Write a sentence that describes the relationship between the dependent variable and the independent variable. (Hint: Ratio language can help.)
(Questions 1 to 3 are worth 1 point each; questions 4 to 6 are worth 2 points each.)
Part 2: Prepare a Table
Assuming that you could complete the activity at the same rate over different time periods, how much of the activity could you complete in two minutes, three minutes, four minutes, and five minutes? (Note: If you spent two minutes doing your activity, then you should edit the table below and use multiples of 2 up to 10).
You may use the table below for your variables.
Time
(minutes)
0 0
1
2
3
4
Part 3: Prepare a Graph
Create a graph to show your relationship. Make sure you include all the parts for a graph and show the data clearly. Include a title for the graph and label the x- and y-axes.
Part 4: Write an Equation
Based on your recorded values, write an equation that represents the relationship between the time you spent doing the activity and the amount of the activity you completed. Make sure to define your variables.
Follow-up Questions
If you were able to maintain this rate of your activity for 12 minutes, how much of the activity would you be able to complete?
How long would it take you to reach 100 for the number of times you did your activity?
Which representation do you believe is the best way to share this information with someone else? This is your opinion. No answer is right or wrong.
(Question 1 is worth 1 point; questions 2 and 3 are worth 2 points each.)

Select the shape that can be shown congruent to this shape below by a rotation? A) A B) B C) C D) D
Answer:
See Explanation
Step-by-step explanation:
The question is incomplete, as the original shape and possible options to select from are not given.
I will use the attached plot to provide a general explanation to answer this solution.
In the attachment, the original image is represented with shape O and the dimension is: 3 by 4 units
Rotation is a rigid transformation, and as such it does not alter the dimension of the original to form a new image.
From the attachment, we have
The dimension of A to be: 4 by 3
The dimension of B to be: 5 by 4
The dimension of A and O are the same; this means that they are congruent.
However, the dimension of B and O are not the same; this means that they are not congruent
Roberto bought snacks to take to his soccer ball practice. He bought a bag of oranges that were $5.65 and a 12 pack of water bottles. The total cost was $12.13 before tax was added. Which equation could be used to find the cost of each water bottle,b?
A. 12(b+5.65)=12.13
B. 5.65(12+b)=12.13
C. 5.65b+12+12.13
D. 12b+5.65=12.13

y= -1
y=5/2x +4
Answer:
the question has some problem so write the question again
Answer:
x = -2
Step-by-step explanation:
y = -1
y = 5/2x + 4
substitute -1 for y
-1 = 5/2x + 4
-5 = 5/2x
-2 = x

Find the mean of the data.
A bar graph, titled “Visits to Your Website”. The vertical axis is labeled “Number of visits”. The horizontal axis is labeled “Day”. For bar 1, the height is 12. For bar 2, the height is 16. For bar 3, the height is 0. For bar 4, the height is 8. For bar 5, the height is 31. For bar 6, the height is 28. For bar 7, the height is 17.
12, 16, 0, 8, 31, 28, 17
12 + 16 + 0 + 8 + 31 + 28 + 17 = 112
112 / 7 = 16

I need help with question 18. The answer is53√3 ft^2. But how do I get there?
Answer:
Hope it helps....
Step-by-step explanation:
Answer:
52√3 ft²
Step-by-step explanation:
sin 60° = (√3) / 2 = h/8
h = 8 x (√3) / 2 = 4√3
cos 60° = 1/2 = a/8
a = 4 b = 15-4 = 11
area = left triangle + right rectangle
area = (4*4√3) / 2 + 11*4√3
= 8√3 + 44√3
= 52√3

a parallelogram has verticies (0,7), (-6,-5), and (9,-5). Which if the following coordinates could NOT be its fiurth vertex?
A. (-15,7)
B. (-3,-17)
C. (3,-17)
D. (15,7)
Answer:
B. (-3, -17)
Step-by-step explanation:
Plotting them out on a graph, the other 3 points are able to be connected as a parallelogram. If you don't have graph paper at home, you can do an online search for "online graph paper" and use that. I personally find it very helpful to be able to see these kinds of things with my eyes.
A coin is tossed 4 times. Find the probability of getting at 4 tails in a row.
Answer:
6.25%
Step-by-step explanation:
Each time you flip a coin, there is a 50% probability of it landing on tails. Each time you flip the coin, the 50% gets multiplied by [tex]\frac{1}{2}[/tex].
[tex]\frac{1}{2}[/tex] to the power of 4 is 0.0625. 0.0625 in percentage form is of course 6.25%
