Mathematics
1 answer:
Firlakuza [10]3 years ago

Use Pythagoras’ theorem:
a^2+b^2=c^2
But we rearrange this formula to make it
c^2-a^2=b^2
So 25^2-15^2=b^2
625-225= b^2 = 400
You now need to find the square root of 400 to find the square root of b
sqrt of 400 is 20
So 20 is the missing length in this triangle

Please tell me the outlier of each set of numbers (3 sets only)!
yulyashka [42]

Hey there!

An outlier in a data set is a number that is WAY larger or WAY smaller than the others in the data set, or does not really fit in the specified "range". In the first one, 452 is way greater than everything else, so it would be the outlier.

In the second data set, 5 would be our outlier because it is much smaller than all the other numbers.

In the last data set, the numbers are pretty close together, but we need to find one that isn't inside the small range. 0.201 appears to be the outlier in this case.

Therefore, here are your answers :)

15: 452

16: 5

17: 0.201

I hope this helps!

If 50 people can fit into 6 rooms. How many people<br> fit into 42 rooms?
fiasKO [112]

Answer:

350 people can fit into 42 rooms

Step-by-step explanation:

So we can write it as a relation fraction equation:

\frac{50}{6}=\frac{x}{42}

Where:

x represents the people can fit in 42 rooms

x=\frac{50*42}{6}

x=350

Therefore, <u>350 people can fit into 42 rooms.</u>

I hope it helps you!
