D) 142 (i can't make the square root symbol)
/18 = 3/2
(3/2 + 4/2) x 2 = 14/2
Let x = the number of marbles for Phil
Then 3x = the number of marbles for Peter
Together they have 3x+x=48 or 4x=48 and x=12
So Phil has x = 12 marbles and Peter has 3x, let x = 12, 3(12) = 36 marbles.
Peter has 24 more marbles than Phil.
To find the median, place the given numbers in order of their value and find the middle number.
Here we have:
57, 61, 58, 54, 68, 51, 49, 64, 50, 48, 65, 52, 56, 46, 47, 55, 42, 60, 62, 43, 69, and 70.
Arranging them in order from least to greatest, we have:
42, 43, 46, 47, 48, 49, 50, 51, 52, 54, 55, 56, 57, 58, 60, 61, 62, 64, 65, 68, 69, and 70.
There are 22 numbers total; the median will be the mean of the middle two numbers, which are 55 and 56.
To find the mean, add the numbers together and divide the sum by 2.
55 + 56 = 111
111 / 2 = 55.5
The median of the ages of the US Presidents at the time of their inauguration is 55.5 years.
