A jar contains 3 red marbles, 6 blue marbles, 5 green marbles and 6 yellow marbles. Assume there is replacement.
Answers
(I believe you are asking for the probability of picking blue then another blue )
So, in the jar, there are 20 marbles, 6 of which are blue, so pick one would be a 6/20 or 3/10 ≈ 33.3%
Assuming that you grabbed a blue marble then it was replaced with another blue marble, you would multiply 6/20 and 6/20 (the individual chances of getting one blue) and get 36/400, which simplifies to 9/100 or 9%
Please correct me if I am wrong, have a good day!

Part b: Find the length of the sidewalk. The walk is the hypotenuse of a right 30-60-90 triangle with horizontal side 2√3. Using the 30° angle as the reference angle, we get the following from the definition of the cosine function:
cos 30° = adj / hyp, or:
√3 2√3
------- = --------
2 hyp
This simplifies to
1 2
-------- = -------
2 hyp
Cross multiplying results in: hyp = 4. The sidewalk length is 4 miles.
a. The width of the park can be found using the sine function, the now-known hypotenuse and the 30° angle:
1 opposite side
sin 30 degrees = ----- = ------------------------- or 2(opp side) = 4.
2 4
Then the opp side, which is the width of the park, is 2.

A right triangle has an angle measure of 52.4 degrees. What is the value of 'x', the missing angle?
Answers
Answer:
The answer is 37.6 degrees
Step-by-step explanation:
Since a right angle is 90 degrees in total, to find the missing degree subtract 52.4 from 90 to find the value of x.
90-52.4= 37.6 degrees
37.6 degrees is your answer

PLSS HELP MEEE IVE BEEN TRYING ALL DAY TO GET THIS ANSWER AND NOTHING PLEASE SOMEONE HELP ME NO LINKSS!! Find the midpoint of the segment below and enter its coordinates as an
ordered pair. If necessary, express coordinates as fractions, using the slash
mark for the fraction bar
(-8,-7) (-7,-8)
Answers
Answer:
midpoint is (-15/2, -15/2)
Step-by-step explanation:
Finding the coordinates of the midpoint is easy. All you have to do is find the average of the x-coordinates and the average of the y-coordinates of the endpoints of the segment.
So, in your case
(-8 - 7)/2 = -15/2 is the x-coordinate
(-7 - 8)/2 = -15/2 is the y-coordinate
Therefore, the midpoint is (-15/2, -15/2)
Answer:
(-7.5, -7.5)
Step-by-step explanation:
Remember that the formula is (x1+x2/2, y1+y2/2)
So, we know that -8 is x1 and -7 is y1. We also know that -7 is x2 and -8 is y2.
Lets plug this into our formula and see what we get.
(-8+-7/2, -7+-8/2)
Now lets find the x in the midpoint.
-8+-7/2 is equal to -15/2. This makes x equal to -7.5.
Now lets find the y in the midpoint.
-7+-8/2 is equal to -15/2 as well. This makes y equal to -7.5.
Now we can tell that the coordinates for midpoint will be:
(-7.5, -7.5)
MISCONCEPTIONS:
Always remember that midpoint is nothing like slope. The mid point is something you can point on a graph, wheareas slope is a function that can be lined on a graph.
The formulas for the two things are different as well. Slope is y/x, where you subtract the ys and xs from each other. In a way, midpoint is the exact opposite, which is adding the xs and ys together.
I hope this helps ;)
