Answer:
The minimum weight of the heaviest 9.85% of all items produced is 5.26 ounces.
Step-by-step explanation:
When the distribution is normal, we use 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 question, we have that:
What is the minimum weight of the heaviest 9.85% of all items produced?
This is the 100 - 9.85 = 90.15th percentile, which is X when Z has a pvalue of 0.9015. So X when Z = 1.29.
The minimum weight of the heaviest 9.85% of all items produced is 5.26 ounces.
Answer:
More than
Step-by-step explanation
This year the club earned $20 more than twice what it earned last year. Let x represent the amount raised last year.
The two words in this problem which tell us about the operation are "More Than"
This year club earned $20 more than than twice it earned last year. This means, to find the earnings of this year, double the earnings of previous year and add 20 to them.
Since, x represents the earnings of last year, we can represent the earnings of this year as:
Twice of x + 20
It costs $.50 to mail a letter of that size.
All letters that are under 3.5 oz take only one stamp to ship. Since 2.7 is less, it would cost only $.50

Answer:
$13,087.50
Step-by-step explanation:
The sale of the 40 shares of stock A at $225 per share will get Juan ...
40 · $225 = $9000
The sale of the 150 shares of stock B at $27.25 per share will get Juan ...
150 · $27.25 = $4087.50
So, the total Juan will receive from the sale of the stocks will be ...
$9000.00 +4087.50 = $13,087.50
