Answer:
A. c + f > 8
5c + 3f < 120
Step-by-step explanation:
Let c = chocolate cakes
Let f = fruit cakes
She must make at least 8 cakes
c+f ≥8
A chocolate cake requires 5 cups of flour, and a fruit cake requires 3 cups of flour and she has only 120 cups of flour
5c+3f ≤120
The two equations are
c+f ≥8
5c+3f ≤120
Answer:
2
Step-by-step explanation:
Since the chip either passes or fails, this problem is one in binomial probability, with p(fail)=0.02 and n=5.
If your calculator features probability functions such as binompdf(n, p), use it.
Mine is a TI-83 Plus.
The probability that exactly two chips will fail is
binompdf(5,0.02,2) = 0.0038. This is quite a small probability.
145.1% as a decimal is 1.451
