12/15 = 400/500
500 people took the survey.
Answer:
The answer is
<h2>(2x + 3)(x + 1)</h2>
Step-by-step explanation:
<u>Write 5x as a sum</u>
2x² + 2x + 3x + 3
Factorize x out
That's
2x ( x + 1) + 3( x + 1)
The final answer is
(2x + 3)(x + 1)

Answer b. The probability that at least 41 of them like to swim is 33%.
Solution:
The probability of an event is always 1 or 100%
The probability of at most 40 of them like to swim is 67% = 0.67
The probability of at most 40 not swimming = 1 - 0.67 = 0.33
Hence the probability of at least 41 people swimming is 33%.
<h3>What is Probability?</h3>
- The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true.
- An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.
- The likelihood that an event will occur increases with its probability. A straightforward illustration is tossing a fair (impartial) coin. Since there are no other conceivable outcomes and the coin is fair, the odds of both the possibilities, "heads" and "tails," are equally likely to occur. As a result, the probability of either occurrence is half.

Answer:
1/2
Step-by-step explanation:
-2y= 8-X
y= -4+X/2
y= X/2-4
recall that: y= mx+c
in the equation y= x/2+C
m=1/2
where m is your slope
