Answer:

YES

Step-by-step explanation:

First, let's find the total number of seats int he airplane.

14 + 64 + 4 * 108 = 510

The airplane has a total or 510 seats.

Half of the number of seats is 510/2 = 255.

Now let's calculate the number of seats being used and compare with 255.

5/7 * 14 + 5/16 * 64 + 5/9 * 4 * 108 =

= 2 * 5 + 4 * 5 + 12 * 4 * 5

= 10 + 20 + 240

= 270

270 seats are being used.

270 is greater than 255, so more than half of the seats are being used.

Answer:

$P=8.869$

Step-by-step explanation:

From the question we are told that:

Mean $\=x =38$

Variance $\sigma=52$

Sample size $n=16$

$X=(33, 43)$

Generally the equation for Chebyshev's Rule is mathematically given by

$A=(1-\frac{1}{k^2})*100\%$

Where

$k=\frac{\=x-\mu}{\frac{\sigma}{\sqrt n}}}}$

$k=\frac{43-38}{\frac{52}{\sqrt 16}}}}$

$k=2.77$

Therefore

Probability

$P=(1-\frac{1}{2.77^2})$

$P=8.869$

Rule: Subtract 2 from the input value

Step-by-step explanation:

Examine the pattern of the input and the corresponding output for the two given ordered pairs:

Input -2 → Output -4

Output - Input = -4 - (-2) = -2

Input 1 → Output -1

Output - Input = -1 - 1 = -2

Therefore to get the output value (y-value), we subtract 2 from the input value (x-value).

$\begin{array}{| c | c |}\cline{1-2} x & y \\\cline{1-2} -3 & -5 \\\cline{1-2} -2 & -4 \\\cline{1-2} -1 & -3 \\\cline{1-2} 0 & -2\\\cline{1-2} 1 & -1 \\\cline{1-2}\end{array}$

As the rule for the function is the subtract 2 from the input value to get the output value, we can write this as:

Output = Input - 2

or as an equation: $y=x-2$
