Answer:
1/4
Step-by-step explanation:
The probability of it being a cardinal is the number of cardinals / the total number of possible birds the hawk could eat.
There are 3 + 5 + 4 = 12 total birds near the bird feeder.
There are 3 cardinals.
So the probability is 3/12 = 1/4 that the cardinal is eaten!
Answer:
Step-by-step explanation:
The information given in the question can be represent in a table format for better understanding with the additional columns as follows:
Items Weights Q₀ Prices P₀ Prices P₁ P₀Q₀ P₁Q₀
Cashew 1 $12.50 $17.00 $12.50 $17.00
Pecans 1 $4.00 $4.00 $4.00 $4.00
Almonds 1 $5.50 $3.00 $5.50 $3.00
Total $22 $24
Can you say what happened to the overall "price level"?
The changes in overall price level can be a result of a condition termed as inflation rate
How might you construct a measure of the "change in price level"?
To construct a measure of the change in price level; we need to determine the consumer price index (CPI).
The consumer price index can be determined by using the relation:


= 109.0%
consumer price index (CPI) is 109.0% ; This implies that there is a 9.9% inflation in the economy.

Answer: 
<u>Step-by-step explanation:</u>
To find the tangent, you need to find the derivative with respect to x.
Then substitute x = 1 into the derivative.
Given: 0 = 2x² - xy - y²
Derivative: 0 = 4x - y' - 2yy'
Solve for y': 2yy' + y' = 4x
y'(2y + 1) = 4x


A. Let x = cheese and
y = chocolate
2x + y = 25
x + y = 20
B. Subtract the second equation from the first.
2x + y = 25
-(x + y = 20)
-—————
x = 5
Plug 5 back in to the second equation and solve for y.
x + y = 20
5 + y = 20
Subtract 5 from both sides.
y = 15
5 cheese and 15 chocolate
Used elimination method because coefficients on the y values were both 1 so it was easy to subtract the equations and eliminate the y variable.
