At a benefit concert, eleven bands have volunteered to perform but there is only enough time for five of the bands to play. How many lineups are possible?
The number of ways that the line up can be possible when eleven bands have volunteered to perform but there is only enough time for five of the bands to play is 462 ways.
How to illustrate the information?Eleven bands have volunteered to participate in the charity concert, but there is only enough time for five of them to do so. This involves combinations and permutations, it should be highlighted.
Therefore, the number of ways that the line up can be possible will be:
n! / (n − r)!
where n is the number of things to choose from and we choose r of them
= 11! / (11 - 5)!5!
= 11! / 6!5!
= 462
There are 462 ways.

Given:
Given the box plots of two different brands of shoes.
Required: Most appropriate comparison of the spreads
Explanation:
From the box plot of brand A,
Minimum value = 65
First quartile, Q1 = 70
Median = 75
Third quartile, Q3 = 80
Maximum value = 85
Also, from the box plot of brand B,
Minimum value = 15
First quartile, Q1 = 50
Median = 60
Third quartile, Q3 = 70
Maximum value = 85
The interquartile range is the difference between the upper quartile and the lower quartile
The interquartile range of brand A is

The value of m such that x +4 is a factor of 5x³ + 18x² + mx + 16 is; -4.
What is the value of m for which x +4 is a factor of 5x³ + 18x² + mx + 16?It follows from the task content that the value of m for which x +4 is a factor of 5x³ + 18x² + mx + 16 is to be determined.
Hence, if x + 4 is a factor, it follows that x = -4 is a zero of the expression.
Therefore; 5(-4)³ + 18(-4)² + m(-4) + 16 = 0.
-320 + 288 - 4m + 16 = 0.
-16 - 4m = 0
4m = -16

Linear function g is shown in the graph. Write the slope-intercept form of the equation representing this function.
g
The equation in slope-intercept form that represents the function is: g(x) = -2x + 1.
How to Write the Slope-intercept Form of an Equation?To write the slope-intercept form of an equation that represents the linear function g, find the slope (m) of the line and determine the y-intercept (b) of the line, then substitute the values into g(x) = mx + b.
Slope of the line that represents function g = change in y/change in x = -6 units/3 units
Slope of the line (m) = -6/3
Slope of the line (m) = -2.
The line intercepts the y-axis at y = 1, therefore the y-intercept (b) of the linear function is b = 1.

What are areas?The area of a shape is the amount of space on the shape
For all regular quadrilaterals, you multiply the side lengths to determine the area
How to determine the correct approach to the problem?From the question, the given parameters are:
Previous radius = 42
New radius = 44
Calculate the change in the radius
dr = New radius - Previous radius
Substitute the known values in the above equation
So, we have
dr = 44 - 42
Evaluate
dr = 2
The above method leads to a differentiation problem where dr = 2
So, the correct approaches to the problem include

The solution for the quadratic equation is -5/2, 2/3
Given,
The equation: 18a² - 30 = -33a
We have to solve this equation
We can convert this equation into a quadratic equation:
18a² + 33a - 30 = 0
Now lets solve this quadratic equation with quadratic formula:
Quadratic formula = [tex]\frac{-b(+-)\sqrt{b^{2}-4ac } }{2a}[/tex]
Here,
a = 18, b = 33 and c = -30
Now we can solve:
[tex]\frac{-b(+-)\sqrt{b^{2}-4ac } }{2a}[/tex]
= [tex]\frac{-33(+-)\sqrt{33^{2} -4(18)(-30)} }{2(18)}[/tex]
