First, we arrange the data from least to greatest:
90, 100, 100, 200, 203, 224, 233, 237, 245, 257, 264, 265, 265, 266, 277, 279, 285, 288, 288, 290, 290, 291, 291, 300
There are 24 data all in all. The mean is calculated by dividing by 24 the sum of all the data.
mean = (5828)/24242.83
The median of the number of jumps is the mean of the 12th and 13th term.

The new length of the string is (13 + 1/4) feet, then the correct option is the last one (counting from the top)
<h3> What is the new length of the string?</h3>
We know that the current string was (8 + 3/4) feet in length. Then they add another piece that measures 4.5 feet.
The new length of the string is given by the addition of the above two lengths, we will get:
L = (8 + 3/4) feet + 4.5 feet
We can rewrite the second length as a mixed number:
4.5 = 4 + 1/2 = 4 + 2/4
Replacing that we get:
L = (8 + 3/4) ft + 4.5 ft
= (8 + 3/4) ft + (4 + 2/4) ft
= (8 + 4) ft + (3/4 + 2/4) ft
= 12ft + 5/4ft = 12ft + (4/4 + 1/4)ft = (13 + 1/4)ft
The new length of the string is (13 + 1/4) feet, then the correct option is the last one (counting from the top).

Distribute the minus sign into the second parenthesis to get 7x-5-3x+2.
Then combine like terms to get 4x-3
In this question, you're solving by adding the two expressions together.
(f+g)(x) is the same as:
3x - 1 + x + 2
Solve:
3x - 1 + x + 2
<em>combine like terms:</em>
4x - 1 + 2
4x + 1
Answer:
4x + 1
