Answer:
“The true mean weight of the piglets is at most 39lbs”would be the alternate hypothesis.
Step-by-step explanation:
Given that the null hypothesis of an experiment is “The true mean weight of the piglets is at least 39lbs”
We have to find the alternate hypothesis.
In hypothesis testing, alternate is the opposite of null hypothesis. If null hypothesis supports one statement alternate hypothesis opposes it. In other words, alternate hypothesis would be the negative of the claim of null hypothesis.
Here the null hypothesis of an experiment is “The true mean weight of the piglets is at least 39lbs”
i.e H0: 
So alternate hypothesis
Ha: 
A + 5 2/3 = 9
a + 17/3 = 9
move the 17/3 over to the other side by subtraction (will need to find a common denominator)
a = 10/3
Hope this helps

Answer:
6 7/12
Step-by-step explanation:
-7 2/3 +(5 1/2) + 8 3/4
Get a common denominator of 12
-7 2/3 * 4/4 +(5 1/2 +6/6) + 8 3/4*3/3
-7 8/12 + 5 6/12 + 8 9/12
Subtract the first two terms first
They have opposite signs so subtract and take the sign of the larger
-7 8/12 + 5 6/12 = -2 2/12
-2 2/12 + 8 9/12
They have opposite signs so subtract and take the sign of the larger
-2 2/12 + 8 9/12 = 6 7/12
