<span>MP3 player is $60
</span><span>The selling price is $105
</span><span>A classmate says that the markup is 175% because $105/$60=1.75 . Is your classmate correct?
No. IT's not correct
Original price $60
Selling price $105
$105 - $60 = $45
So
45/60 x 100 = 75%
Price is markup 75% from $60 to $105</span>
Answer:
0.281 = 28.1% probability a given player averaged less than 190.
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean
and standard deviation
, the z-score 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 p-value, we get the probability that the value of the measure is greater than X.
A bowling leagues mean score is 197 with a standard deviation of 12.
This means that 
What is the probability a given player averaged less than 190?
This is the p-value of Z when X = 190.



has a p-value of 0.281.
0.281 = 28.1% probability a given player averaged less than 190.

Answer:
-4
Step-by-step explanation:
let n be least.
3n-12=4(n+n+2)
3n-12=8n+8
3n-8n=8+12
-5 n=20
n=-4
