Joel reads on the package of cereal that the net weight of the box is 64 oz. He calls the company to find out how they guarantee this and they tell him that the filling machine is set to fill each box with 64.8 oz with a standard deviation of 0.6 oz. He graphed
the normal distribution of the package weights. Using his graph, what percentage of boxes does the shading represent? Is this
appropriate?
A)
The shading represents 90% of the boxes. Yes, this is appropriate as 90% of
the boxes are at least the stated weight.
B)
The shading represents 9% of the boxes. Yes, this is appropriate as less
than 10% of the boxes are under the stated weight.
C)
The shading represents 9% of the boxes. No, this is not appropriate as
more than 10% of the boxes are under the stated weight.
D)
The shading represents 90% of the boxes. No, this is not appropriate as
less than 10% of the boxes are under the stated weight.

answer: i wpould go with c

step-by-step explanation:

delaney would like to make a 5lb nut mixture that is 60% peanuts and 40% almonds.

she has several pounds of peanuts and several pounds of a mixture that is 20% peanuts and 80% almonds.

let 'p' represent the number of pounds of peanuts needed to make the new mixture, and  

let 'm' represent the number of pounds of the 80% almond-20% peanut mixture.

:

p + m = 5

therefore

m = (5-p)

write an equation based on the percent of peanuts

1p + .2m = .6(5)

replace m with (5-p)

p + .2(5-p) = .6(5)

p + 1 - .2p = 3

p - .2p = 3 - 1

.8p = 2

p = 2/.8

p = 2.5 lbs of peanuts required

then

5 - 2.5 = 2.5 lbs of the peanut/almond mixture required

:

a) what is the system that models this situation?

p + m = 5

1p + .2m = .6(5)

divide the numbers

step-by-step explanation:

both triangles are similar because 2 is just smaller than the big one 1 is similar because they are facing different way's but are similar to each other
