The tens digit of 31 is 3. There are 3 tens in this number and that is equal to 30. Also, the ones digit of this number is equal to 1. The answer to this item are therefore 30 and 1. Hope This Helps! :)
I'm not sure if that's the correct method of finding that (it could be, I was just never shown that kind of method). What I did was multiply everything out, that way you have two numbers vs two equations. Then add those two numbers and turn that into scientific notation.
Answer: We concluded that annual income and education level are not independent.
Step-by-step explanation:
For the given situation, the null and alternate hypothesis can be formulated as:
annual income and education level are independent.
annual income and education level are not independent.
Given, the value of test statistic is 24.32 and the critical value of test statistics is 13.32.
i.e. the test statistic value is greater than the critical value, thus we have enough evidence to reject the null hypothesis.
Therefore, we reject null hypothesis .
So , we concluded that annual income and education level are not independent.
Answer:
Step-by-step explanation:
<u>Use the law of cosines:</u>
- cos C = (a² + b² - c²)/(2ab)
<u>Apply to the given triangle and solve for x:</u>
- cos x = (52² + 48² - 70²)/(2*52*48)
- cos x = 108/4992
- cos x = 0.02163461538
- x = arccos 0.02163461538
- x = 88.76°
