Answer:
The answer is 71.61%.
Step-by-step explanation:
Households discarding paper week is given to be normally distributed with a mean, 
= 9.4 lb.
The normally distributed distribution has a standard deviation given as 
= 4.2 lb.
The proportion of households that throw out at least 7 lb of paper a week is to be found.
Therefore we have to find p(X ≥ 7) which can be written as
p(X ≥ 7) = 1 - p(X < 7)
= 1 - p( Z < 
)
= 1 - p( Z < 
)
= 1 - p( Z < -0.571 )
= 1 - 0.2839
= 0.7161
Therefore the percentage of households that throw out at least 7 lb paper a week is 71.61%
One quarter (25%) of the data is in any quartile. That is the meaning of the term "quartile."
25% of data is in quartile 1
Answer:
Absolute change = 6.5
Relative change = 61.91%
Step-by-step explanation:
We are given the following in the question:
Number of months Jacob took for his first step = 17
Number of months Clyde took for his first step = 10.5
We have to compare the number of months it took Clyde to take his first steps to the number of months it took Jacob using absolute and relative change.
Absolute change:
- It is simple difference of the second quantity and first quantity.
Absolute change
= Number of months Jacob took for his first step - Number of months Clyde took for his first step
Relative change:
- It is the percentage of absolute change to the first quantity.
Relative change =
Answer:
C.) Begin at 74. Travel 19 units to the right.
Step-by-step explanation:
You begin at 74 because that is the number the equation is starting out with. You travel to the right because you are adding 19 units.
Answer:
The decrease is 21%
Step-by-step explanation:
So lets say the Original area is Pi X (Radius^2)
Lets call Radius as R
For the new radius, it would be: R + 0.1R which is 1.1R
The new area is: Pi X 1.1R^2, which going further is 1.21 after squaring 1.1.
The Original area is: Pi X Radius^2
To find the percent decrease, subtract the new area by the original, cross out Pi X Radius squared and you are only left with 21%
I am in middle school so I don't know if it is going to be incorrect, but I ask you to give it a try and tell me if it was right or not. I have barely done this topic but recently I had a bonus homework question on a question almost exactly like this and this is the way I did it and I was correct. Thanks! Hope it helped! :)
