Answer:
(a) =210
(b) = 0.11
Step-by-step explanation:
Sampling distribution of the mean = 50 × 6 × 0.7= 210
Now to get the null divide 0.7 by 6
This gives 0.11
Answer: dependent events
Step-by-step explanation:
Dependent events are refered to as the events that occur when occurrence of one of the events has an effect on the chances of the other event occuring as well.
For a dependent event, we should note that the outcome of the second event affects the dependent event. In a case when it doesn't affect each other, it's called independent event.
We will set each parentheses equal to 0
x - 4 = 0
x = 4
-5x + 1 = 0
x = 1/5
The lesser value will be 1/5
The greater value will be 4
This problem is about componded interest. The formula for compounded interest is:

In this case, Initial = 300, r = 0.06 and t=10 so the total amount in the account after 10 years is:

The amount after 10 years is 573.26.
