Answer:
77%
Step-by-step explanation:
Since the chance of it happening is 22%, the chance of it not happening is 88%.
To find the probability that none will have it, we have to multiply the probabilities together:
0.88(0.88) = 0.7744 or 77%
The reciprocal of 2 5/7 is 7/19 because 2 5/7 as a mixed number is 19/7
Answer:
1) 2
2) 0.5
Step-by-step explanation:
To find how many cups of popcorn used per cup of cereal, use the given point on the graph (1, 2) to find the proportions.
1) To find how many cups of popcorn are used per cup of cereal, place the amount of popcorn in the numerator of a fraction, and the amount of cereal in the denominator:
2/1
Then simplify the fraction to find the proportion:
2/1 = 2
Harlan uses 2 cups of popcorn per cup of cereal.
2) To find the amount of cups of cereal per cup of popcorn, do the same thing but place cereal in the numerator and popcorn in the denominator:
1/2
Then simply:
1/2 = 0.5
Harlan uses 0.5 cups of cereal per cup of popcorn.
