The easiest way to do this is to split that numerator up into each of its individual expressions over the denominator, like this:
and then divide each expression one at a time. In the first expression, -5 diivided by 5 = -1. Now for the exponents. As long as the base is the same you will subtract the exponents, lower from upper. Our bases are all w's, so we're good.
so that expression is
. Now for the second expression. 10 divided by 5 is 2, and, using our rules for dividing exponents with like bases,
. So that expression is
. For the last term there, 5 divided by 5 is 1, and
. Now we will put all of them together to get a final solution of
. There you go!

Answer: Point of estimation = 32.60
Margin of error = 1.175.
95% confidence interval would be (81.95,84.45).
Step-by-step explanation:
Since we have given that
n = 49
Average = $32.60
Standard deviation = $5
We need to find:
1) Point of estimation for the mean of the population:
2) At 90% level of confidence, z = 1.645
Margin of error would be
So, Margin of error = 1.175.
3) At 90% level of confidence, interval would be
Hence, 90% confidence interval would be (31.43,33.76).

Teddy will buy at least 15 bags of ice for the graduation picnic.
Each large bag of ice costs $4.00, and each small bag of ice costs $2.50. He will spend up to $50 on ice. The set of inequalities that describe this scenario are
4x + 2.5y lesser than or equal 50
x + y greater than 15
The combination of bags of ice that Teddy can buy is
b) 6 large bags and 10 small bags
From the option b, the total number of large and small bags is greater than 15 and the total cost is 49( it doesn't exceed 50)
