The answer is 1.5 buddy or 3/2
For this question, we have to use the Pythagorean theory since we're dealing with a right triangle.
a² + b² = c²
We're given the value of the hypotenuse and a leg, therefore we're looking for the value of the other leg.
Now let's plug in the given data into our equation.
2² + b² = 5²
4 + b² = 25
b² = 25 - 4
b² = 21
√b² = √21 = b
The correct answer is B) √21
The answer is No.
The reason being is that in
, if you divide 2 by 5, it is .4
Which is less than .5

Answer:
0.0818.
Step-by-step explanation:
This question can be solved using the binomial theorem because the probability of success is fixed.
Total adults = n = 20
Required attempts = r = 12
Probability of success = p = 3/4 = 0.46
Binomial Theorem formula:
P(X=r) = nCr * p^r * (1-p)^(n-r).
Substituting the values:
P(X=12) = 20C12 * 0.46^12 * (1-0.46)^8
P(X=12) = 125970 * 0.46^12 * (0.54)^8 = 0.0818 (to the nearest 3 significant figures).
So the probability that exactly 12 people use their smart phones in meetings or classes out of 20 is 0.0818!!!
