Let X be the random variable representing the number
of coins that Matt set aside after three flips.

We have to run n from 0 to 100 and m from 0 to (100-n),
Find the binomial law, then compute the mean like this:

Hope this gives a hint.
First, we split the figure into two shapes, a triangle and a trapezoid. First, we know that the length of the base of the right triangle is 2, because in a 30-60-90 triangle, the side next to the 60° is half of the hypotenuse. Then, the length of the height would be 2 times root 3, which is 3.46410161514. Height is 3.46410161514 meters and base is 2 meters. We multiply the base times the height, and we get 6.92820323028 meters squared. This is the area of the triangle. Since we know that the base of the triangle is 2, we can do 5-2 to find the first base of the trapezoid, which is 3. We know that the height is 3.46410161514, the first base is 3, and that the second base is 5, so we plug it into our equation which is base1 + base2 over 2 times the height. We plug it in and get approximately 13.85641. Then we round to the tenths place, and we get 13.86 meters squared of the figure. Brainliest?
Mode means the number that apperss the most
median is the number in the middle when you arrange them in numerical order
ok so
you take the unbers fom the left most collumn and pair it with each number in the right side of the line, the left collumn is the tens place and the right hand side is the ones
so the th enumbers are
32,41,41,50,56,57,62,70,70,72,72,72,73,74,91,92,94,94,94,94
mode=most common number
94 appears 4 times which is most
mode=94
median is number in very middle number
20 terms
72 is in middle
mode=94
72=median
D is answer
Answer: C) 50% of the students scored below 70%
<u>Step-by-step explanation:</u>
Mean is the average. To find the mean (aka average) you add up all of the scores and divide by the number of tests.
B) The mean can be 70 without any test scoring 70% so B is not true.
A) Since B is not true, then A is not a valid option.
D) We don't know any of the other data so don't know if it is skewed left, skewed right, or normal. Therefore, option D is not true.
C) If the average is 70%, then half received grades above that score and half received grades below that score. So, option C is TRUE!
