Answer:
Now that his car is 5 years old, he would like to know whether the variability of gas mileage has changed. He recorded the gas mileage from his last eight fill-ups; these are listed here. Conduct a test at a 10% significance level to infer whether the variability has changed.
Step-by-step explanation:
Answer:
180 -93+37= 180 -124 = 56
Step-by-step explanation:
interior angles of a triangle are 180 degrees
so 180 - 124 = 56
In the given question, the options are related to linear pair .
And according to linear pair, if a line cuts another line at a point, then the sum of the adjacent angles formed at that point is 180 degree.
Therefore, from the given diagram we can say that, angles WXY and YXZ are linear pair, so there sum have to be 180.
And the correct option is the third option .
In your problem about the finding the potential voltage at the center of the sphere where as its radius is 5cm is charge such that the potential of its surface is 10volts. So the possible answer to this is also 10 volts, because the potential in the center and in the surface of the sphere is constant and the same.
