Answer:
The quantity of pepper cheddar cheese required = 2.5 kilograms
The quantity of Pennsylvania Jack required = 4.5 kilograms
Step-by-step explanation:
Let x = Quantity of pepper cheddar cheese
y= Quantity of Pennsylvania Jack
As per given , we have the following system of equations:
Multiply 8 to equation(1) , we get
Eliminate (3) from (2) , we get
Put value of x in (1) , we get
Hence, the quantity of pepper cheddar cheese required = 2.5 kilograms
The quantity of Pennsylvania Jack required = 4.5 kilograms
Answer:
y =
The focus of the solar oven's reflector is (0,a)
Step-by-step explanation:
The missing figure( i.e diagram) from the question is attached below:
Now ; given that :
The focus of the sun's rays is at a point L = 5 inches away from the vertex of the reflector. Also the distance of the parabolic curve be a= L = 5
So the equation for a cross section of the oven's reflector with its focus on the
positive y axis and its vertex at the origin is expressed as:
x² = 4 L y
x² = 4 (5) y
x² = 20 y
y =
The focus of the solar oven's reflector is (0,a)
Answer:
(A) a=1,b=5,c=9
Step-by-step explanation:
We want to simplify for values of a, b and c which satisfies:
Converting our result to mixed fraction
We want to find the median for the given density curve.
The value of the median is 4.5. ({3+6)/2}
Let's see how to solve this.
First, for a regular set {x₁, ..., xₙ} we define the median as the middle value.
The difference between a set and a density curve is that the density curve is continuous, so getting the exact middle value can be harder.
Here, we have a constant density curve that goes from 3 to 6.
Because it is constant, the median will just be equal to the mean, thus the median is the average between the two extreme values.
Remember that the average between two numbers a and b is given by:(a + b)/2
So we get: m = (6 + 3)/2 = 4.5
So we can conclude that the value of the median is 4.5, so the correct option is the second one, counting from the top.
