A right triangle has the 3/4/5 rule, which is pythagorean theorum.
A^2 (A squared) + B^2 (B squared) = C^2 (C squared).
You can test this.
Let's try the first option, A.
3^2 (A) + 4^2 (B) = 5^2 (C).
3^2 = 9, B^2 = 16, C^2 = 25.
9 + 16 = 25.
A.) is the correct answer.
Okay, I went through a lot of work to try solving this, so here goes!
First, turn the mixed numbers into improper fractions.
6 1/4 --> 25/4
3 3/5 --> 18/5
Next, we need to multiply the two improper fractions together.
25 x 18 450
--- --- = ---
4 x 5 20
Then, we need to turn 450/20 into a mixed number. To do this, we divide.
450/20=22 10/26
We're almost done. Last step is to simplify the mixed number, specifically 10/26. We need to find GCF of 10 and 26, which is 2.
10/2=5
26/2=13
= 5/13

The answer for this question is -6x-11
Answer:
Step-by-step explanation:
Given mean = 84,
Standard deviation = 2,
Sample 64,
95% confidence interval: z = 1.96
Applying empirical rule , means that 95% of data fall within two standard deviations.
ME = = 0.49
Rounding this to 0.5
CI = 83.5< mean < 84.5
Outside of this range= x ≤ 83.5 and ≥ 84.5
