Let x = the number of reserved seats sold and y = the number of general seats sold.
1) x+y = 41,000 "41,000 people attended..."
2) $14(x)+$5(y) = $340,000 "The day's receipts were $340,000."
Rewrite equation 1) as x = y-41,000 and substitute into equation 2)
2a) 14(41,000-y)+5y = 340,000 Simplify and solve for y.
2a) 574,000-14y+5y = 340,000 Combine the y-terms.
2a) 574,000-9y = 340,000 Subtract 574,000 from both sides.
-9y = -234,000 Divide both sides by -9.
y = 26,000 and...
x = 41,000-26,000
x = 15,000
15,000 paid $14.00 for reserved seats.
26,000 paid $5.00 for general seats.

A study indicates that 37% of students have laptops. You randomly sample 30 students. Find the mean and the standard deviation o
Brilliant_brown [7]

Answer:

The mean and the standard deviation of the number of students with laptops are 1.11 and 0.836 respectively.

Step-by-step explanation:

Let <em>X</em> = number of students who have laptops.

The probability of a student having a laptop is, P (X) = <em>p</em> = 0.37.

A random sample of <em>n</em> = 30 students is selected.

The event of a student having a laptop is independent of the other students.

The random variable <em>X</em> follows a Binomial distribution with parameters <em>n</em> and <em>p</em>.

The mean and standard deviation of a binomial random variable <em>X</em> are:

\mu=np\\\sigma=\sqrt{np(1-p)}

Compute the mean of the random variable <em>X</em> as follows:

\mu=np=30\times0.37=1.11

The mean of the random variable <em>X</em> is 1.11.

Compute the standard deviation of the random variable <em>X</em> as follows:

\sigma=\sqrt{np(1-p)}=\sqrt{30\times0.37\times(1-0.37)}=\sqrt{0.6993}=0.836

The standard deviation of the random variable <em>X</em> is 0.836.
