Answer:
x = 
y = 24
Step-by-step explanation:
-3x - 8y = 20 .... (1)
-5x + y = 19 .... (2)
What we can do is take the (2) equation
-5x + y = 19
and solve for y by adding 5x to both sides
y = 24
now that we have y we substitute it in for y in equation (1)
-3x - 8(24) = 20
-3x - 192 = 20
we want to solve for x so we need to get its self.
add 192 to both sides
-3x = 212
now we divide both sides by -3. It's going to be a fraction.
x = 
Answer:27
Step-by-step explanation:first you need 40 x 12 for the area for your gravel
so 480 divided by 18 = about 27
c = amount of chocolate donuts
m = amount of maple donuts.
so we know the total in all is 41 donuts, thus c + m = 41.
we also know that whatever c is, m is 25 fewer than that, m = c - 25.

In a symmetric histogram, you have the same number of points to the left and to the right of the median. An example of this is the distribution {1,2,3,4,5}. We have 3 as the median and there are two items below the median (1,2) and two items above the median (4,5).
If we place another number into this distribution, say the number 5, then we have {1,2,3,4,5,5} and we no longer have symmetry. We can fix this by adding in 1 to get {1,1,2,3,4,5,5} and now we have symmetry again. Think of it like having a weight scale. If you add a coin on one side, then you have to add the same weight to the other side to keep balance.
Answer:
Process Capability ratio / Index = 0.133
Step-by-step explanation:
From the question, we are told:
Upper limit of 9.16 ounces
Lower limit of 9.12 ounces
Process width of 0.05 ounces.
what is the process capability ratio
Process Capability ratio or Index formula
= Cp = (USL - LSL)/(6 × Standard deviation)
Cp = 9.16 - 9.12/6 × 0.05
Cp = 0.04/0.3
Cp = 0.13333333333
Approximately = 0.133
