Determine if the sides form a right triangle.
olganol [36]
<h2>Answer:</h2>

Yes.

\rule{70mm}{2pt}

Step-by-step explanation:

To tackle such questions use the Pythagoras Theorem.

Provided a triangle whose sides are 3√2, 3√3 and 3√5 and are asked to check or determine if the sides form a right triangle or not.

We know that hypotenuse is the longest side. Let's call 3√5 = Hypotenuse side, 3√2 = Perpendicular and 3√3 = Base. So,

Using formula: (Hypotenuse)² = (Perpendicular)² + (Base)²

\implies{\sf{(3\sqrt{5})^2 = (3\sqrt{2})^2 + (3\sqrt{3})^2}}

\implies{\sf{9(5) = 9(2) + 9(3)}}

\implies{\sf{45 = 18 + 27}}

\implies{\sf{45 = 45}}

LHS = RHS

<u>So, from above calculations we can say that the given sides form a right triangle.</u>

The dot plots show rainfall total for several spring storms in highlands areas an lowlands areas what is the median rainfall for
tankabanditka [31]

*See attached picture showing the dot plots referred to

Answer:

16mm

Step-by-step Explanation:

Given the dot plot showing rainfall for Highlands storms, we can find out the median rainfall for Highlands storms by mere observing the dot plot and locating where the middle value falls within the data set that is represented on the dot plot.

Thus, we have 44 data sets that is being represented on the plot, with one dot representing one data set for rainfall. This means, since the total number of data set is even, our median lies between the 22nd and the 23rd dot or data set that is being plotted.

From the dot plot for Highlands, the 22nd and 23rd dots are 16 and 16 respectively.

Therefore, median rainfall for Highland storms = (16 + 16) ÷ 2 = 16.
