1) √3 √7 = √21
2) √5 √245 = √5 √5 * 49 = √5 * 7√5 = 7 √5 * 5 = 7 √25 = 7 * 5 = 35
3) √77 ÷ √11 = as is. can't be simplified.
4) (√59)² = 59 ; the square root was cancelled by squared.
5) 3√6 x 8√7 = 3 * 8 √6 * 7 = 24 √42
6) 5√3 x 6 √3 = 5 * 6 √3 * 3 = 30 √9 = 30 * 3 = 90
7) 40√30 ÷ 5√3 = (40 / 5) * (√30 /√3) = 8 * ((√3 *10) / √3) = 8 √10
8) (6√5)² = 6² * √5² = 36 * 5 = 180

In a survey of students, 1162 stated they cheated and 2468 stated they did not. If one student is randomly selected what is the

liraira [26]

Answer:

$n = 1162 +2468 =3630$

And the probability that they cheated and we can use the classical definition of probability given by:

$p =\frac{successes}{Total}$

And replacing we got:

$p=\frac{1162}{3630}= 0.320$

So then the probability of people cheated is 0.320 or 32% approximately

Step-by-step explanation:

For this problem we know that in a survey of students, 1162 stated they cheated and 2468 stated they did not.

The total of people is given by:

$n = 1162 +2468 =3630$

And the probability that they cheated and we can use the classical definition of probability given by:

$p =\frac{successes}{Total}$

And replacing we got:

$p=\frac{1162}{3630}= 0.320$

So then the probability of people cheated is 0.320 or 32% approximately
