It's not much but to find the mean you add up all of the numbers in the set, and then divide by how many numbers there are. so like, if you have : 2, 2, and 3. You'd add them and get 7, then divide by 3 because there are three separate numbers.

The object of the game is to toss a beanbag in the circular hole of a 48-by-24-inch board. If the diameter of the circle is 6 in
larisa [96]

Answer:

Geometric probability of an object hitting a circular hole is 0.0245.

Step-by-step explanation:

We have given,

A board of size 48 by 24 inch. There is a circular hole in the board having diameter 6 inches.

So,

Area of a board = 48 × 24 = 1152 square inches

And area of circular hole = π×r²   {where r = diameter/2  = 6 / 2 = 3 inches}

Area of circular hole = π×3² = 9π = 28.27 square inches

Now, we need to find the geometric probability of an object will hit the circle.

Geometric probability =  Area of circular hole / Area of board

Geometric probability = \frac{28.27}{1152}

Geometric probability = 0.0245

hence geometric probability of an object hitting a circular hole is 0.0245.

Calculate for y given that mean of 20,2y,25,y,30 is 27​
masha68 [24]

Answer:

y = 218

Step-by-step explanation:

Mean = (Sum of all numbers)/(How many numbers present)

27 = (20 + 2y + 25 + y + 30)/27

27 = (3y + 75)/27

3y + 75 = 729

3y = 729 - 75

3y = 654

y = 218
