Answer:
The equation representing the problem is .
Mr. Patel used 5 bags of seeds.
Step-by-step explanation:
Given:
Number of times bird feeder refilled =24
Number of cups of seeds used each time = 6 cups
Number of seeds each bag holds = 32 cups.
We need to write the equation to represent the problem.
Solution.
Let the total number of bag of seed be 'x'.
First we will find the Total number of cups of seeds used.
Now we can say that;
Total number of cups of seeds used can be calculated by multiplying Number of times bird feeder refilled by Number of cups of seeds used each time.
framing in equation form we get;
Total number of cups of seeds used =
Now We know that;
1 bag holds = 32 cups
Total number of bags required =
So we can say that;
Total number of bags required is equal to Total number of cups of seeds used divided by number of seed hold by each bag.
framing in equation form we get;
Hence the equation representing the problem is .
On solving we get;
Since bags cannot be bought in half or in decimal value.
Hence we can say Mr. Patel used 5 bags of seeds.
Answer: Option 'D' is correct.
Step-by-step explanation:
Since we have given that
Event A: You get a red car
and
Similarly,
Event B: You get a convertible
and
So, if A and B are independent , then they must satisfy,
So,
Hence, Option 'D' is correct, which states that the probability of getting a red convertible is 0.08.
