Let us first assume that the operator between 5x^3 and 3 is addition. What Louise did was incorrect, as she did not follow the proper way of expanding a binomial. The actual steps to take when taking the square of a binomial is as follows:
(5x^3 + 3)^2 = (5x^3 + 3)(5x^3 + 3)
25x^6 + 15x^3 + 15x^3 + 9
25x^6 + 30x^3 + 9
The actual answer is <span>25x^6 + 30x^3 + 9.</span>
Answer:
<h2>125 is 1 dev above, so it's 13.5 + 2.35,</h2><h2>so it's B. 0.159</h2><h2 /><h2>And i think the proportion of infants with birthweights between 125 oz and 140 oz is :</h2><h2>D. 0.136</h2>
It is given that probability of a student being on the debate team is 0.42
So, P(D) = 0.42
It is given that probability of a student being on the math team is 0.26
So, P(M)= 0.26
The probability that he is on both teams is .20
So, 
We have to determine the probability his is on the math team if we know he is on the debate team. This is the case of conditional probability.
So, 

= 0.476
= 0.48
Therefore, the probability that he is on the math team if we know he is on the debate team is 0.48.
Option 1 is the correct answer.
