Answer:
14
Step-by-step explanation:
We can use the Pythagorean theorem since this is a right triangle.
a^2 +b^2 = c^2
where a and b are the legs and c is the hypotenuse
x^2 + 48^2 = 50^2
x^2 +2304=2500
Subtract 2304 from each side
x^2 +2304-2304=2500-2304
x^2 =196
Take the square root of each side
sqrt(x^2) =sqrt(196)
x =14
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: 4 (153 - 98)
formula is a^2-b^2=(a+b)(a-b)
factor out the GCF:
4(153−98)
both terms are not perfect squares so
you cant factor it further.
