You are given Richard’s piano practice for 3 piano solos. Every piano sol
he makes takes 5/12 hour. You are asked to find how long Richard is going to
practice his piano solo. So we have for every 1 piano solo he makes this is
equal to 5/12 hours. This can be best represented by ratio and proportion.
1 piano solo/(5/12 hour) = 3 piano solo/(number of hours)
Number of hours = 3 piano solo/ (1 piano solo/5/12 hours)
<u>Number of hours = 5/4 hours or 1.25 hours.</u>
Answer:
C. 34.15 oz
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:

How heavy does a box have to be for it to be labeled overweight?
Top 5%, so X when Z has a pvalue of 1-0.05 = 0.95.
So X when Z = 1.645.




So the correct answer is:
C. 34.15 oz
Answer:
56%
Step-by-step explanation:
Step 1:
96 divided by $3 = $32
Step 2:
204 divided by $3= $68
Step 3:
