The first aircraft had 192 seats, the second aircraft had 104 seats and the third aircraft had 88 seats
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
An independent variable is a variable that does not depends on other variable while a dependent variable is a variable that depends on other variable.
Let a represent the sits in the first aircraft, b represent the second aircraft and c represent the third aircraft.
The first aircraft has 88 more seats than the second aircraft. Hence:
a = b + 88 (1)
Also, The third aircraft has 16 fewer seats than the second aircraft:
c = b - 16 (2)
If their total number of seats is 384:
a + b + c = 384 (3)
From the three equations:
a = 192, b = 104, c = 88
The first aircraft had 192 seats, the second aircraft had 104 seats and the third aircraft had 88 seats

Answer:
Minimum: $25,200
Maximum: $44,800
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:
What are the minimum and the maximum starting salaries of the middle 95% of the graduates
Minimum: 50 - (95/2) = 2.5th percentile.
Maximum: 50 + (95/2) = 97.5th percentile
2.5th percentile:
X when Z has a pvalue of 0.025. So X when Z = -1.96.
The minimum is $25,200
97.5th percentile:
X when Z has a pvalue of 0.975. So X when Z = 1.96.
The maximum is $44,800
Answer:
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
