ahrayia [7]

Answer:

75.062cm^{2}

Step-by-step explanation:

To find the missing side use pythagorean theorem

So 6^{2} +b^2=8.5^2

Solve for b, b= 6.021

To find the area use \frac{1}{2}bh

So \frac{1}{2}(6.021+19)(6)= area

And you get 75.062

The histogram shows the speeds of downhill skiers during a competition. Estimate the mean of the data set displayed in the histo
Ostrovityanka [42]

Answer:

≈50.6

Step-by-step explanation:

Not sure what precision level this problem is looking for, but for right-skewed distributions, we know that the mean is going to be pulled right and therefore the mean should be larger than the median. To a high confidence level, the mean should fall between 50 and 59, or in the third column.

If a single estimation is wanted, assume the values inside each column are uniformly distributed:

\displaystyle\\\widehat{\mu}=\frac{34.5\cdot 4+...+74.5\cdot 2}{4+9+4+4+2}\approx \boxed{50.6}
