If you mean something like 4^3 * 4^14 you have to obey two rules.
1. The base number must be the same for both numbers making up the product.
2. The powers must be added.
In this case 1 and 2 both can be obeyed.
4^3 * 4^14 = 4^(3 + 14) = 4^17
60 is the answer I hope this helps a lot.
Answer:
30 percent
Step-by-step explanation:
15 + 13 + 4 + 10 + 8 = 50
15/50 = 30/100
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:
Step-by-step explanation:
First triangle is a 45-45-90 triangle. In most basic form, the two equal sides have length 1 and the hypotenuse has length √2. Do not write x√2.
Second triangle: The shortest side is 1, the longer side is √3 and the hypotenuse is 2. You could verify this using the Pythagorean Theorem:
2² = 1² + (√3)² is true.
