c) 
d) There are two possible answers only considering real coefficients:
(i) 
(ii) 
e) 
Step-by-step explanation:
Now we proceed to solve each algebraic equation:
a) Factor 
This binomial is of the form
. In this case, we can rewrite and factor the equation below:



b) Factor 
This binomial is of the form
. In this case, we can rewrite and factor the equation below:



c) Nicole is factoring
by using the rule
. What will she use for the value of
?
From this rule we find that
, that is:




d) Which binomial is a difference of squares?
A binomial is a difference of square if and only if
. There are two possible answers only considering real coefficients:
(i) 
(ii) 
e) Factor 
This binomial is of the form
. In this case, we can rewrite and factor the equation below:



There are four sides
6.5 x 4 = 26
Answer:

For this case we can conclude that with 98% of confidence the true proportion of Drosophila in a population would be between 0.34 and 0.38.
But that doesn't means that we have 98% of PROBABILITY that the true proportion would be between 0.34 and 0.38, because we are constructing a confidence interval with sample data and we can't analyze this using probability.
Then the best answer is:
2. False
Step-by-step explanation:
For this case we have a confidence interval for the proportion of Drosophila in a population with mutation Adh-F to be given by:

Answer:
x= 110°
Step-by-step explanation:
if you continue drawing the top purple line you will have a triangle with three angles
70° ; is given
180-140= 40°; is the same angle as the supplement angle of 140° (complementary angles are congruent)
180-70-40 = 70°; because sum of angles in a triangle is 180°
So angle x= 180 -70 = 110 because are a linear pair
<span>If Dingane has $8.00, and thirty percent of that money is from five cent coins, then 8 x 0.3 = $2.40 of Dingane's money is made of five cent coins. In this case the number of five cent coins is the number of cents divided by five: 240/5 = 48. Therefore, Dingane has forty-eight five-cent coins.</span>
