Given the equation 9x = -63, the numerical value of x is -7.
<h3>What is the solution to the given equation?</h3>
Given the equation in the question;
9x = -63
To determine the value of x, we divide both sides by the coefficient of x.
9x = -63
9x/9 = -63/9
x = -7
Given the equation 9x = -63, the numerical value of x is -7.

Answer:
The probability that the plane is oveloaded is P=0.9983.
The pilot should take out the baggage and send it in another plain or have less passengers in the plain to not overload.
Step-by-step explanation:
The aircraft will be overloaded if the mean weight of the passengers is greater than 163 lb.
If the plane is full, we have 41 men in the plane. This is our sample size.
The weights of men are normally distributed with a mean of 180.5 lb and a standard deviation of 38.2.
So the mean of the sample is 180.5 lb (equal to the population mean).
The standard deviation is:

Then, we can calculate the z value for x=163 lb.

The probability that the mean weight of the men in the airplane is below 163 lb is P=0.0017

Then the probability that the plane is oveloaded is P=0.9983:

The pilot should take out the baggage or have less passengers in the plain to not overload.
The answer should be f(x)=20(2.5)^x
How?
the graph crosses the f(x) axis at 20 but that's common in all 4 equations. However, when x=1, f(x)=50. We have to know try all the equations by substituting these values in ( both sides are equal).
f(x)=20(2.5)^x
substitute f(x)=50, x=1
50=20(2.5)^1
50=20*2.5
50=50
5814/27 = 215.33
215 x 27 = 5805
5814-5805 = 9
