Answer:
Not sure exactly which equivalent expression you are looking for but my goal would be to write it without the negative exponent.
Step-by-step explanation:
They have the same exponent and it is multiplication.
There is a law of exponent that says 
.
So we have 
equals 
.
Let's simplify (4*7)^(-2).
Since 4*7=28, we can say 
.
Some people really hate that negative exponent. All that - in the exponent means is reciprocal. So 
.
A U B = {1, 2, 3, 4, 5, 6, 7}
Step-by-step explanation:
- Step 1: Find A U B. Union of two sets A and B are the set of all elements in set A and set B.
A = {1, 2, 5, 7} and B = {3, 4, 6, 7}
A U B = {1, 2, 3, 4, 5, 6, 7}

The question is asking for the lower bound of the 95% two tailed Confidence interval of the normally distributed population.
95% C.I. is given by 200 + or - 1.96(25) = 200 + or - 49 = (151, 249)
Therefore, the minimum weight of the middle 95% of players is 151 pounds.
