Answer:
Step-by-step explanation:
Multiplying 5 by itself is the same thing as raising it to the second power:
We multiply 2 by itself two seperate times. That's the same thing as raising 2 to the second power to the second power or in simpler terms raising two to the fourth power:
Since only multiplication is present, we can combine the two terms to get:

Answer:
If the p-value is less than a given significance level, you reject the null hypothesis and accept the alternative hypothesis.
Step-by-step explanation:
Suppose you have a business in which you'd like to make a change to increase your business. After making the change, you can use a significance test it. To conduct a significance test, you make a null hypothesis which states essentially that no effect happened. You also make an alternative hypothesis that states the change had an effect. You then test the two to see which one stands. In a significance test, using the p-value from your sample you compare it to the null and alternative hypotheses. You make a conclusion when:
- If the p-value is less than a given significance level, you reject the null hypothesis and accept the alternative hypothesis since the evidence is in favor of it.
If the p-value is greater than the significance level, then you fail to reject the null hypothesis and cannot conclude. There isn't evidence in favor of the alternative hypothesis.
Let b repesent the amount Timmy has invested in bonds. Then b/3 represents the amount Timmy has invested in stocks. His earnings are
158.40 = 0.05*b + 0.07*(b/3)
158.40 = (0.22b)/3 . . . . . . . . . . combine terms
158.40*3/0.22 = b = 2160
Timmy has $2160.00 invested in bonds.
