Answer:
20%
Step-by-step explanation: The percent of error formula is |(theoretical value-actual value)/actual value|=percent of error. Substitute the values in. |(2.8-3.5)/3.5|=|(-0.7)/3.5|=0.2. The percent equal to 0.2 is 20%.
Answer:
One is a question and the other is a prediction.
Step-by-step explanation:
A quantitative research is based on numbers and data.
A research hypothesis is a prediction or an explanation that will be proven right or wrong given the results found in the research. And the quantitative research question is a question that will define the porpuse and will guide what we want to get out of the investigation.
Thus, the characteristic that distinguishes them is:
One is a question and the other is a prediction.
Where the question is the quantitative research question and the prediction is the research hypothesis.
Answer:
45°
Step-by-step explanation:
The angles should add to 180°. so we can say 2x+45+x=180
3x+45=180
3x=135
X=45°
A.)Hey, there! If you look at the table below, you can see that the output is always 6 more than the input. This means that the rule for this is 
. The first one, for example, would be (4) + 6 = 10 because you are substituting for the value of x. The second would be (5) + 6 = 11 and so on.
B.) This problem is designed to trip you up. Notice how it says to write an equation for the cost of the number of razors you buy? It doesn't say anything about finding the monthly fee, which means that the number of razors (x) will be our variable. The equation will look like this: 
, because even if you don't buy any razors, you still have to pay the $12 monthly fee.
Hope this was helpful. :)
