The absolute value of Tan(x) means that, while x = multiples of 45 degrees or Pi/4, the values are: Pi/4, 3Pi/4, 5Pi/4, 7Pi/4.
Answer:
A) The proportions of wins is the same for teams wearing suits as for teams wearing jeans
Step-by-step explanation:
Although the question says that they will "test the claim at the 0.05 level that the proportion of win is the same for teams wearing sutis as for the teams wearing the jeans", the claim, that will be expressed in the alternative hypothesis, is that there is a significant difference between the two proportions.
The null hypothesis, the one that this test try to nullify, will state that there is no significant difference between the two proportions. Or, saying the same, that the proportions are equal.
The right answer is A, which states that the two proportions (as this is a test on the difference of proportions) are equal.
Answer:
No correlation
Step-by-step explanation:
- The points shows the value that takes the variable "y" when "x" takes some specific value.
- Possitive correlation would happend whenever higher values of x imply higher values of y (both vary in the same way)
- Negative correlation would happen whenever higher values of x imply lower values of y (they vary in opposite direction).
- In this specific case, there is no patterns of behavior that indicates that when x varies in certain way, y would do it in a specific way. This means that there is no correlation between them,
Answer:
20.7=16.8
Step-by-step explanation:
.. the upper left of the radical sign is the power of the radical. Putting a 2 here means square root. Putting a 3 here means cube root , etc
It means that you have to find the solution of the systems of equations.
