The answer is -21 I just took the test
Answer: Choice B) {3, 5, sqrt(34)}
=====================================
Explanation:
We can only have a right triangle if and only if a^2+b^2 = c^2 is a true equation. The 'c' is the longest side, aka hypotenuse. The legs 'a' and 'b' can be in any order you want.
-----------
For choice A,
a = 2
b = 3
c = sqrt(10)
So,
a^2+b^2 = 2^2+3^2 = 4+9 = 13
but
c^2 = (sqrt(10))^2 = 10
which is not equal to 13 from above. Cross choice A off the list.
-----------
Checking choice B
a = 3
b = 5
c = sqrt(34)
Square each equation
a^2 = 3^2 = 9
b^2 = 5^2 = 25
c^2 = (sqrt(34))^2 = 34
We can see that
a^2+b^2 = 9+25 = 34
which is exactly equal to c^2 above. This confirms the answer.
-----------
Let's check choice C
a = 5, b = 8, c = 12
a^2 = 25, b^2 = 64, c^2 = 144
So,
a^2+b^2 = c^2
25+64 = 144
89 = 144
which is a false equation allowing us to cross choice C off the list.
Answer:
42 out of 80
Step-by-step explanation:
Given function:
- surveys 80 people
- 42 voted
- to find the experimental probability that the next person surveyed say yes or no..
<u><em>Thinks:</em></u>
- 42 out of 80 means 42:80 in ratio form
- if 42:80 that they’ll vote for Seth Gleason then this means that the next person have 42:80 chance to vote for Seth Gleaso...
<u><em>Forms:</em></u>
- 0.525
- 42/80.. simplify form=21/40.
- 52.5%
Therefore, the percentage the next person would vote for Seth Gleason is a percentage of 52.5% and also have a ratio of 42:80.
