Answer:
The test statistic for this test is 3.82.
Step-by-step explanation:
The null hypothesis is:
The alternate hypotesis is:
Our test statistic is:
In which X is the sample mean, is the value tested at the null hypothesis, is the standard deviation of the population and n is the size of the sample.
In this question:
So
The test statistic for this test is 3.82.
Answer: I think the answer is A.
Step-by-step explanation:
I don't know how to explain but if you test this on a calculator, it'll make sense.
2/3= 50/75
you just multiply the 3 by 25 to get 75...so obviously the 2 must also be multiplied by 25
Next , solve as you would solve any two -step inequality. Since 2 is added to , you can get by itself on one side of the inequality by subtracting 2 from both sides. Then, to get by itself on one side of the inequality, you need to multiply both sides by 2.D
Answer:
Yes, 2+4=6 6 > 5
Explanation:
For three line segments to be able to form any triangle you must be able to take any two sides, add their length and this sum be greater than the remaining side.
