2.64 divided by 6 equals 0.44. one ounce costs 44 cents
5. (0,1)
6. (-2,-2)
7. (-1,-3)
8. (-3, 2)
Answer:
6
Step-by-step explanation:
To find the missing number, subtract: 52 - 46 = 6
So 10 questions is 100% you missed 30% of the questions so you would do 100%-30% which is 70%
Answer:
They spend at least 69.48 minutes reading the paper.
Step-by-step explanation:
Problems of normally distributed samples are solved using the z-score formula.
In a set with mean
and standard deviation
, the zscore of a measure X is given by:

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this problem, we have that:

For the 10% who spend the most time reading the paper, how much time do they spend?
They spend at least X minutes, in which X is the value of X when Z has a pvalue of 0.90. So it is X when Z = 1.28.




They spend at least 69.48 minutes reading the paper.
