PSYCHO15rus [73]2 years ago
8 0

Answer:

Step-by-step explanation:

3)\frac{5x}{2}+125 = 180\\\\\frac{5x}{2}=180-125\\\\\frac{5x}{2}=55\\\\        5x    = 55*2\\\\          x    =\frac{55*2}{5}\\\\         x = 11*2 = 22

4) 3x+ 42 + 90= 180

3x + 132 = 180

        3x = 180 -132

        3x = 48

          x = 48/3

         x = 16

A cafe sells puffs. 5/9 are beef and 1/3 are chicken. The remaining 18 are tuna. Calculate 1. What fraction of the puffs are tun
Ksivusya [100]
Let n be the total number of puffs. Now we can write:
n=\frac{5}{9}n+\frac{1}{3}n+18
Adding the fractional value of n, we get:
n=\frac{5+3}{9}n+18
Simplifying and rearranging gives us:
n-\frac{8}{9}n=18
Therefore we can simplify to get:
\frac{1}{9}n=18
and finally
n=18\times9=?
The fraction of the puff that are tuna is found from:
\frac{18}{18\times9}=\frac{1}{9}

Given the box plot, will the mean or the median provide a better description of the center?
yuradex [85]

Answer:

The median, because the data distribution is skewed to the right

Step-by-step explanation:

If the longer part of the box is to the right (or above) the median, the data is said to be skewed right. If the longer part is to the left (or below) the median, the data is skewed left.  The data is skewed right.  The median would be a better estimate, because one or two numbers on the high end will cause the  numbers to be skewed to the right, and the mean to be high
