Answer:
7 ( x - 0.75 ) = 2.80
Step-by-step explanation:
7 ( x - 0.75 ) = 2.80
7x - 5.25 = 2.80
7x = 2.80 + 5.25
x = 8.05/7
x = 1.15
------------------------------
1.15 - 0.75 = 0.4
(0.4)*7 = 2.8
Answer:
Step-by-step explanation:
Given is a list of prices in dollars for one night at different hotels in a certain region
To find range, variance and std deviation.
Mean 155.75
Standard Error 23.80782434
Median 150
Mode #N/A
Standard Deviation 67.33869616
Sample Variance 4534.5
Kurtosis -1.593759971
Skewness 0.344624422
Range 172
Minimum 86
Maximum 258
Sum 1246
Count 8
Thus we find range = 172 $. This gives an idea about the lowest and highest difference.
Variance = Average of squares of deviations from the mean= 4533.329 $^2gives us an idea about the dispersion of data. This helps to have an idea about the price rise or low in different hotels
Std deviation is square root of variance 67.33 $ shows an idea about the dispersion and also coefficient of variation as a ratio of mean to std deviation.
3/6 divide numerator and denominator by 3 and get 1/2
12/20 divide the numerator and denominator by 2 ,and get 6/10 divide by 2,and get a final answer of 3/5.
8/24 divide the numerator and denominator by 8 ,and get 1/3.
30/40 divide the numerator and denominator by 10 ,and get 3/4
I hope this helps you,and good luck.
Answer is 13-1/2 cups
Step by step
We know 1 cup is = 2/9 of a liter
We know we are working with 3 liters = how many cups
So first I want my 3 liters in a like denominator based fraction
1 liter is = 9/9 so 3 liters is = 27/9
I want to divide 27/9 by 2/9, the part of a liter that equals 1 cup
When I divide a fraction, I flip one fraction and multiply
27/9 x 9/2 = 243/18, simplify to 13-1/2 cups
Problem solved
You can check your work
Multiply 13-1/2 cups x 2/9
Change your whole number to a mixed fraction
27/2 x 2/9 = 54/18, simplify it equals 3 liters!
