Answer: A. H0: Mean= 5 and Ha: Mean is not equal to 5.
Step-by-step explanation:
Definitions:
- Null hypothesis is a statement describing population parameters according to the objective of the study. It takes "≤,≥,=" signs.
- Alternative hypothesis is a statement opposite to the null hypothesis elaborating population parameters according to the objective of the study. It takes ">, <, ≠" signs.
Given: The diameter of a spindle in a small motor is supposed to be 5.8 millimeters.
If the spindle is either too small or too large, the motor will not work properly. so, Mean diameter ≠ 5.8 to work correctly.
i.e.
So,
The required null and alternative hypotheses:
H0: Mean= 5 and Ha: Mean is not equal to 5.
Answer:
<h2>Reflection and translation.</h2>
Step-by-step explanation:
The picture shows the preimage ABCD and the image A'B'C'D'.
Notice that both images are at the same distance from the x-axis, which implies a reflection across the x-axis. Them, the image was translated 1 units to the left.
Therefore, the right answers are reflection and translation.
Answer:
A and B
Step-by-step explanation:
The "zeros" of the quadratic equation simply refers to what x equals when q(x) = 0.
Set the equation equal to zero as so: 0 = x^2 - 9, and solve!
9 = x^2
+/- 3 = x, when q(x) = 0.
This means that the two points you are trying to find are (-3, 0) and (3, 0)!
So you divide by 2 because there is 2 buildings. You get 760. Now, just take 200 away from one building, and 200 away from the other, and you get 560 for Building A, and 960 from Building B.
