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:
21.16

Starting from the theory we have the following equation:
Using the data supplied in the exercise, we have subtracting the mean and dividing by the standard deviation:
solving for "c", knowing that fi is a tabulating value:
therefore the value of c is equal to 21.16

Answer: Option B is the cheaper deal (the 12 batteries for $14.76)
===========================================================
Explanation:
For the first deal we can say
3 batteries = 4.80 dollars
3/3 batteries = 4.80/3 dollars .... divide both sides by 3
1 battery = 1.60 dollars
The unit price for the first deal is $1.60 per battery.
----------------------------------
For the second deal we could say
12 batteries = 14.76 dollars
12/12 batteries = 14.76/12 dollars .... divide both sides by 12
1 battery = 1.23 dollars
The unit price for the first deal is $1.23 per battery.
This is the cheaper deal.
----------------------------------
So in short, you're dividing the total cost over the number of items to get the unit price.
