A manufacturer makes bags of popcorn and bags of potato chips. The average weight of a bag of popcorn is supposed to be 3.05 oun
Jobisdone [24]

Answer:

The popcorn bag assembly line is closer to the specifications given because its z-score is closer to the standard mean than the potato chip bag assembly line.

Step-by-step explanation:

z- score for pop corn

average weight for a pop corn bag=3.05

Standard deviation for a pop corn bag=0.04

z=x-mean/standard deviation

z=3.03-3.05/0.04

z=-0.5

z- score for potato chips

average weight for a potato chips bag=5.01

Standard deviation for a potato chips bag=0.05

z=x-mean/standard deviation

z=5.07-5.01/0.05

z=1.2

As z-score for pop corn bag -0.5 is closer to standard mean i.e. 0 than the z-score for potato chips bag, so,

The popcorn bag assembly line is closer to the specifications given because its z-score is closer to the standard mean than the potato chip bag assembly line.

If D varies directly as T and d=320 when T=8 find d when t=10
mart [117]

Answer:

400

Step-by-step explanation:

320 divide by 8 will find the unit rate and the unit rate is 40.

Now times 10

40 times 10 = 400

A farmer decides to enclose a rectangular​ garden, using the side of a barn as one side of the rectangle. What is the maximum ar
Artyom0805 [142]
The farmer is going to construct a rectangular shaped barn with dimensions

a  and  b, 

such that 2a+2b=2020, (the perimeter is 2 width+2 length)

dividing by 2, we have a+b=1010

writing b in terms of a, we have b=1010-a

so f(a)=a(1010-a) is the function which calculates the area depending on a.

for example the area enclosed is the dimensions are a= 10, b=1000

is f(10)=10*(1010-10)=10*1000=10,000 square feet.


f(a) is a polynomial function of degree 2, that is a quadratic.

The graph of a quadratic polynomial is a parabola, in our case, a parabola which opens downward since the sign of the coefficient of the largest term of the quadratic, is negative.

since the quadratic is given in factorized form, we easily find that the roots are a=0 and a=1010

since f(0)=0 and f(1010)=0.

in the middle of these points, we have 1010/2=505, which is the x-coordinate of the vertex.

f(505) gives us the highest point, which is f(505)=505(1010-505)=505^{2}=255,025 ft squared.

the highest point of the parabola, represents the largest value of f so the largest possible area.


Answer: 255,025 ft squared.
