Answer:
Yes, She is correct.
Step-by-step explanation:
Pythagorean theorem:
base² + altitude² = hypotenuse²
k² + k² = j²
Add the like terms. Like terms have same variable with same power.
2k² = j²
<span>Krystal's rate = 1 floor in 16 min. = 1/16 floors per min.
Working together their rate = 1 floor in 5.76 min. = 1/5.76 floors per min.
We need to determine Perry's rate, so we need to equate their combined rate with the sum of the individual rates.
Let Perry's time = x
In equation form, we can write:
1/16 + 1/x = 1/5.76
Solve for x:
(x+16)/16x = 1/5.76 -> 5.76(x+16) = 16x -> 10.24x = 92.16 -> x = 9
So, Perry would take 9 mins. to do the floor alone.
I hope this helped!

What is the meaning of probability in math?
- Probability is simply how likely something is to happen.
- Whenever we're unsure about the outcome of an event, we can talk about the probabilities of certain outcomes—how likely they are.
- The analysis of events governed by probability is called statistics.
Three Types of Probability
- Classical: (equally probable outcomes) Let S=sample space (set of all possible distinct outcomes).
- Relative Frequency Definition
- Subjective Probability.

Answer:
No, not correct.
Step-by-step explanation:
Note that 8 * 4.3 can be broken up as follows:
8 * (4 + 0.3)
and that 4*8 =32, and that 0.3(8) = 2.4 (not 0.24).
Then 8 * (4 + 0.3) becomes 32 + 2.4 = 34.4
