Title:
<h2>The worker's highest wage is $400.</h2>Step-by-step explanation:
Due to the joining of the 11th worker, the firm's output increases 10 units.
The price of each unit is $40.
The price of 10 units are .
The worker's wage will be highest if he will be paid all the amount which is the resultant of the output's increase, that is (90 - 80) = 10 units.
Answer:
She ran
Step-by-step explanation:
To find the answer you multiply the amount of races (9) by the length of each race (7/10 km).
Answer:
The estimation for the number of newborns who weighed between 1724 grams and 5172 grams is 595.
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:
Proportion of newborns who weighed between 1724 grams and 5172 grams.
This is the pvalue of Z when X = 5172 subtracted by the pvalue of Z when X = 1724. So
X = 5172
By the Central Limit Theorem
has a pvalue of 0.9772
X = 1724
has a pvalue of 0.0228
0.9772 - 0.0228 = 0.9544
Estimate the number of newborns who weighed between 1724 grams and 5172 grams.
0.9544 out of 623 babies. SO
0.9544*623 = 595
The estimation for the number of newborns who weighed between 1724 grams and 5172 grams is 595.
