Answer:
b. Normal data is never one of the inference assumptions.
Step-by-step explanation:
A categorical data specifies among two or more groups, which one each observation belongs to, and one or more explanatory variables that can be used to predict this membership.
So, there are two propositions in statistical inference for categorical data
1. That each data in a cell is independent of the others.
2. That samples are randomly drawn.
Thus, there is no room for normality.
Answer:
39
Step-by-step explanation:
If x=1, then it's equal to 140/(1+9, or 10)+(1+4, or 5)^2, and that is equal to 140/10+5^2, or 140/10+25, and 140/10=14, and 14+25=39

Answer:
80 feet
Step-by-step explanation:
Let x represent the height of the pole.
We have been given that a telephone pole has a wire attached to its top that is anchored to the ground. The distance from the bottom of the pole to the anchor point is 41 feet less than the height of the pole. So the distance between bottom of pole to the anchor point would be .
The wire is to be 9 feet longer than the height of the pole, so length of the wire would be .
We know that length of the wire would be hypotenuse of right triangle, so we can use Pythagoras theorem as:
Since the distance from the bottom of the pole to the anchor point is 41 feet less than the height of the pole, so 20 feet cannot be height of the pole.
Therefore, the height of the pole is 80 feet.
