1 whole cake= 1/4 + 1/4 + 1/4 + 1/4
1/4= 0.25
So we multiply 10 4/5oz per 1/4 cake by four to find out how many ounces are needed for 1 whole cake.
T= total ounces for 1 whole cake
T= (1 ÷ cake portion)(# ounces)
T= (1/0.25)(10 4/5)
change mixed fraction to improper
T= (4)(54/5)
multiply 4 by the numerator
T= (4*54)/5
T= 216/5 ounces for whole cake
T= 43 1/5 ounces for whole cake
Hope this helps! :)
The variance is the total of the squared distances of the given data from the mean.
This can be calculated through the equation,
σ² = summation of X² / N - μ²
where σ² is the variance X's are the data, N is the number of terms, and μ is the mean.
summation of X² = 100² + 100² + 120² + 120² + 180² = 81200
N = 5
μ = (100 + 100 + 120 + 120 + 180) / 5
μ = 124
Substituting these values to the equation for variance,
σ² = (81200/5) - 124² = 864
Thus, the variance is equal to 864.
(-1.5,3) Y=3 which is up 3 and a horizontal line and 2x+y=0 can be written as y=-2x so in order to get -1.5 you have to make y=3 cause y=3 and when you do that it should look like 3/-2=-2/-2x so x=-1.5
