Answer:
Step-by-step explanation:
Start box
180 = 89+42+x
180-89-42=x
49 = x
2nd box
180 = 84+58+x
180-84-58=x
38 = x
3rd box
180=74+2x
180-74=2x
106/2 = x
53 = x
4th box
180=102+2x
180-102=2x
78/2 = x
39 = x
4th box
180 = 73+81 +x
180-73-81=x
26 = x
5th box
180=2*54+x
180 - 2*54 = x
72 = x
6th box
180=62-2x
180-62=2x
118=2x
118/2=x
59 = x
7th box
180 = 2*68 + x
180-2*68=x
44 = x
Answer:
The correct option is (b) 0.3333.
Step-by-step explanation:
The standard deviation of the sampling distribution of sample mean is known as the standard error .
The standard error is given as follows:
The information provided is:
Compute the standard deviation of the sample mean as follows:
Thus, the standard deviation of the sample mean is 0.3333.
Answer: The Jolene's unit rate in dollars per pound of grain is 0.25.
Explanation:
It is given that the Jolene is making a line graph that represents the price of grain and the number of pound purchase.
The number of pounds are shown on x-axis and the price in dollar are shown on y-axis.
The cost of 1 pound is 0.25, therefore the point (1,0.25) lies on the line.
The cost of 4 pound is 1, therefore the point (4,1) lies on the line.
The unit rate in dollars per pound of grain is the the slope of the line.
The slope of a line is,
Therefore, Jolene's unit rate in dollars per pound of grain is 0.25.
The first one is 9/16 you have to make 54 and 96 a fraction such as 54/96 then simplify
the second one is 1/5 you have to make 4 and 20 a fraction like this 4/20 then simplify
hope this helps!!
