Answer:
Please read the answers below.
Step-by-step explanation:
Let's calculate the four means between 100 and 135, this way:
1. Arithmetic mean:
(100 + 135)/2 = 117.5
2. Weighted mean:
We will assign equal weight to both numbers : 5
(100 * 5 + 135 * 5)/10 = (500 + 675)/10 = 1,175/10 = 117.5
3. Geometric mean:
√100 * 135 = √13,500 = 116.2 (Rounding to the next tenth)
4. Harmonic mean:
2/(1/100 + 1/135) = 2/(0.01 + 0.0074) = 114.9 (Rounding to the next tenth)
132, if you add four to 50, and keep going until you get to 20
Answer:
Since it has smaller absolute and relative errors, 355/113 is a better aproximation for 
than 22/7
Step-by-step explanation:
The formula for the absolute error is:
Absolute error = |Actual Value - Measured Value|
The formula for the relative error is:
Relative error = |Absolute error/Actual value|
I am going to consider the actual value of as 3.14159265359.
In the case of 22/7:
22/7 = 3.14285714286.
Absolute error = |3.14159265359 - 3.14285714286| = 0.00126448927
Relative error = 0.00126448927/3.14159265359 = 0.00040249943 = 0.04%
In the case of 355/113
355/113 = 3.14159292035
Absolute error = |3.14159265359 - 3.14159292035| = 0.00000026676
Relative error = 0.00000026676/3.14159265359 = 0.000000085 = 0.0000085%
Since it has smaller absolute and relative errors, 355/113 is a better aproximation for than 22/7
My common denominator is a 08 cause as I look at the fraction I have a1/2 also falod 1/4 which I had to take of the one to make a 0to subtract to the 2 to give it a 12 to be able to take from the four we have and that is how I came up with a common denominator of 08
The question seems incomplete, but if you are trying to figure out how much each dress costs, The answer would be $30.
To find the answer all you need to do is;
1. Subtract the price of the jeans ($40) From the total price.
160-40=120
2. Now we know the total price of the Dresses, and we also know she bought 4 of them, this means we can divide the total price ($120) of dresses, by the number (4) of dresses bought.
120/4 = 30.
So therefor, each dress costs $30 Dollars.
Hope this Helps! - Giz
