The hypotenuse of a right triangle is √18 units. what are the lengths of the legs of the triangle? How many different answers ca
storchak [24]
Since a right triangle has special rules to it such that the hypotenuse squared equals the sum of the squares of the other 2 sides. In other words, if the hypotenuse = c, and the 2 smaller sides are a and b, then:
{c}^{2}  =  {a}^{2}  +  {b}^{2}
Solving for c (hypotenuse), we get:
\sqrt{({c}^{2})} =   \sqrt{({a}^{2}+{b}^{2} )} \\ c =  \sqrt{({a}^{2}+{b}^{2} )}
Therefore c is the root of the square of the other sides. So by having root18, it's like saying:
\sqrt{18} =  \sqrt{({a}^{2}  +  {b}^{2} )}  \\ 18 = {a}^{2}  +  {b}^{2}
Getting rid of the square root, so sides a and b must have their squares total 18:
the only squares < 18 are: 16 (4×4), 9 (3×3), 4 (2×2), and 1 (1×1)
of those above added in any order of two of them, only 16+4
18 = 17 + 1 -  -  >  \sqrt{17}  \: and \: 1 \\ 18 = 16 + 2 -  -  >  \sqrt{16} \: and \:  \sqrt{2}  \\ ... \: 4 \: and \:  \sqrt{2}  \\ 18 = 15 + 3 -  -  >  \sqrt{15} \:  and \:  \sqrt{3}
18 = 14 + 4 -  -  >  \sqrt{14} \:  and \:  \sqrt{4}  \\ ... \sqrt{14} \: and \: 2  \\ 18 = 13 + 5 -  -  >  \sqrt{13} \: and \:  \sqrt{5}   \\ 18 = 12+ 6 -  -  >  \sqrt{12} \:  and \:  \sqrt{6}
18 = 11 + 7 -  -  >  \sqrt{11} \:  and \:  \sqrt{7}  \\ 18 = 10 + 8 -  -  >  \sqrt{10} \:  and \:  \sqrt{8}  \\ ... \sqrt{10} \:  and \: 2 \sqrt{2}  \\ 18 = 9 + 9 -  -  >  \sqrt{9}  = 3 \: and \: 3
I HOPE THAT IS ALONG THE LINE THAT WAS ASKED FOR!!! :-D

you roll a blue number cube and a green number cube. find P ( a number less than 2 on the blue vube and odd number on the green
Kruka [31]

ON the blue cube there are 4 numbers greater than 2 and on the blue cube, 3 of the numbers are odd. As soon as BOTH outcomes have to happen (AND), you multiply the probabilities.

A set of average city temperatures in May are normally distributed with a mean of 20.66 ^\circ \text{C}20.66
Angelina_Jolie [31]

Answer:

0.9962

Step-by-step explanation:

The z score shows the number of standard deviations by which the raw score is above or below the mean. If the raw score is above the mean then the z score is positive but if the raw score is less than the mean then the raw score is negative. The z score is given by:

z=\frac{x-\mu}{\sigma}\\ \\\mu=mean,\sigma=standard\ deviation, x=raw\ score

μ = 20.66°C, σ = 2°C

For x < Singapore temperature, i.e. x < 26

z=\frac{x-\mu}{\sigma} =\frac{26-20.66}{2}=2.67

From the normal distribution table P(x < 26) = P(z < 2.67) = 0.9962
