The answer is c bc adjacent angles that are side by side and share one segment
First part of question states;
A poll conducted in 2013 found that the proportion of of U.S. adult Twitter users who get at least some news on Twitter was 0.52 The standard error for this estimate was 0.024, and a normal distribution may be used to model the sample proportion.
Answer:
<u>True</u>
<u>Step-by-step explanation:</u>
From the statement above and after constructing the 99% confidence interval for the proportion of U.S. adult Twitter users we can infer that the 95% confidence upper and lower bounds are 0.52 and 0.79, which means that there's a 99% confident that the true percentage of U.S. adults Twitter users who get some news through Twitter is between the upper and lower bounds of the confidence interval.
Answer:
The quick answer I think will help you in the long run is that (f*g)(x) is just another way of saying f(x)*g(x). If that is enough, then ignore the rest of my response. Otherwise, keep reading.
For this problem
Step-by-step explanation:(f*g)(x) = f(x)*g(x)
You are given f(x) = 3x + 2 and g(x) = x^2 + 1. Simply substitute these expressions as follows:
f(x)*g(x) = (3x + 2)*(x^2 + 1)
Notice how I put each expression in parentheses. This practice will help immensely when dealing with more complicated expressions like this. Next, we simplify:
(3x + 2)*(x^2 + 1) = (3x)(x^2) + (3x)(1) + (2)(x^2) + (2)(1) <-- the foil method
= 3x^3 + 3x + 2x^2 + 2 <-- simplify each term
= 3x^3 + 2x^2 + 3x + 2 <-- reorganize and group like terms
hope this helped!
