Since we are given that
the mean is 15.2 oz
standard deviation of 0.5 oz
and simple random sample of 7
then we have an
<span>Exact normal distribution with mu equal to 15.2 and sigma equal to 0.4
since the samples are simple and random</span>
The answer is the second choice, because (9) X 3 = 27.
Answer:
x = 9/25, y = 7/25, z = 4/25
Explanation:
step 1: solve for y in first equation to use substitution
y = -2x + 1
step 2: insert into second equation to eliminate y variable and work with two variables
3(-2x+1) + z = 1 (now distribute)
-6x + 3 + z = 1 (bring over the -3)
-6x + z = -2
step 3: now left with -6x + z = -2 and x + 4z = 1, so eliminate z
-6x + z = -2 (multiply by 4)
4(-6x + z = -2)
-24x + 4z = -8
-
x + 4z = 1 (brought down third equation)
-25x = -9
x = 9/25
then just plug in x into the third equation to solve for z, followed by plugging it into the first equation to solve for y. you should end with y = 7/25 and z = 4/25
Answer:
Three benefits of the agriculture revolution that Jared Diamond lists in his argument are as follows:
- Agriculture Revolution promoted specialization in agriculture and also provide necessary time to other people who can learn other things.
- Agriculture can support economic development of the country, according to Diamond's argument.
- Diamond also raises the question on inequality between sex in agriculture, as women were thought to be meant for agriculture, which was wrong.
