Answer:
mxn will b the order of matrix
Step-by-step explanation:
A group of 20 friends are going to travel to a school reunion together, 7 of them can drive. They have a 7 seat car (1 driver and 6 passengers), a 5 seat car (1 driver and 4 passengers) and the remaining 8 will take a bus. How many ways can the friends travel (ignoring passenger seat positions within each vehicle)? Give an exact answer, do not round. Do not include commas or dots in your answer.
Using the combination formula, it is found that there are 99768240 ways in which they can travel.
The passenger seat positions are not important, which means that the order is not important, which is why the combination formula is used.
Combination formula:
[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by:
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
In this problem:
In the first car, 7 of the 20 friends are going to sit.In the second, 5 of the remaining 13 are going to sit.In the bus, the remaining 8.The, the number of ways is given by:
[tex]N = C_{20,7}C_{13,5}C_{8,8}[/tex]
[tex]N = \frac{20!}{7!13!} \times \frac{13!}{5!8!} \times \frac{8!}{0!8!} = 99768240[/tex]
There are 99768240 ways in which they can travel.

Which is the correct first line for dividing the function f(x)= x^3-12x+16 by (x-2) using synthetic division
Answer:
C
Step-by-step explanation:
Write the equation of a line that passes the point (-6,9)and is perpendicular to a line that passes through the points (-2,1) and (6,7).
Answer:
y = 4/3x + 1.
Step-by-step explanation:
The equation of the lines passing through (2,1) and (6,7) is:
y - 7 = (7-1)/(6- -2)(x - 6)
y - 7 = 6/8(x - 6)
y = 3/4(x - 6) + 7
y = 3/4x + 5/2.
So the line perpendicular to it has slope -1/3/4 = -4/3:
y - 9 = -4/3(x + 6)
y = -4/3 x - 8 + 9
y = 4/3x + 1.

What is the measure of the angle
Hey! The measure of the angle is 127
The angle is a total of 180 degrees.
We have to find the total of what's in between the two blue lines.
To make it easier, we can take the total of what's not in the blue lines, 53, and subtract it from 180. This gives us 127. So in between both the blue lines, measures 127. Or, you can just count up from 53 to 180 individually.

If I use 1 pound of sausage for 3/4 pound of cheese how much sausage do I need if I use 1 pound of cheese
Answer:
1.33Step-by-step explanation:
3/4 = 0.75 pound
1 : 0.75 = x : 1
x = 1 * 1 : 0.75
x = 1.33
--------------check
1 : 0.75 = 1.33 : 1
1.33 = 1.33
the answer is good
Answer:
[tex]1 \frac{1}{3}lb \: sausage[/tex]
Step-by-step explanation:
What Iike to do is make it like a ratio.
So you have one pound of sausage per 3/4lb of cheese
[tex] \frac{1lb \: sausage}{( \frac{3}{4} )lb \: cheese} = \frac{sausage}{1lb \: cheese} [/tex]
Then you just make that sausage the subject of the equation by multiplying 1lb cheese to both sides of the equation, and you have your answer.
[tex]1lb \: cheese \times \frac{1lb \: sausage}{0.75 \: lb \: cheese} = sausage[/tex]

For slope-intercept form, solve the equation for y.
For standard form, solve the equation for the constant and keep x and y on the same side.
Ex) 3x - 2y = -3
-2y = -3x - 3
y = -3x/-2 - 3/-2
y=3x/2 + 3/2

the side lenghts of a triangle are 14,15, and x units
9514 1404 393
Answer:
1 < x < 29
Step-by-step explanation:
The triangle inequality requires the sum of the two shortest sides exceed the longest side.
When x and 14 are the shortest:
x + 14 > 15
x > 1
When 14 and 15 are the shortest:
14 +15 > x
29 > x
Then the requirement for the length of x is ...
1 < x < 29
