DENIUS [597]

Answer:

Step-by-step explanation:

base² + Altitude² = Hypotenuse²

x² + 9² = 13²

x² + 81 = 169

x² = 169 - 81

x² = 88

x = $\sqrt{88}$

$x = \sqrt{2*2*2*11}=2\sqrt{2*11}\\\\x=2\sqrt{22}$

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:

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