To charter a bus to carry students to New York City, the cost is $100 to make the booking , plus $25 for each student who is a passenger on the bus. Then, the cost function C(x) giving the cost if x students are ( what is m and b) mxtb
The value of m is $25 and value of b is $100, the cost is $300 and the number of students is 12.
As per the given relation in the question, we see that b is calculated once and m is calculated based on the variable value x, which is the number of students. Hence, for correct calculation, value of m is $25 and value of b is $100.
The cost if 8 students are passengers will be calculated by keeping the value of x and other constants as per the above answer.
Cost = 25×8 + 100
Cost = 200 + 100
Cost = $300
Number of students will again be found as the value of x, by keeping the values as specified above.
400 = 25x + 100
25x = 400 - 100
25x = 300
x = 300 ÷ 25
x = 12
Hence, value of m is $25 and value of b is $100, the cost is $300 and the number of students is 12.

At a bakery, one customer pays $5.67 for 3 bagels and 4 muffins. Another customer pays $6.70 for 5 bagels and 3 muffins. Which system of equations can be used to determine the cost x (in dollars) of one bagel and the cost y (in dollars) of one muffin at the bakery?
The bagel costs $0.89 and a muffin costs $0.75
How to create a system of equations?Let B = Bagel cost
Let M = Muffin cost
Thus, from the given question parameters, the system of equations that can be used to determine the cost x is;
3B + 4M = 5.67 ------(1)
5B + 3M = 6.70 ------(2)
Multiply the 1st equation by 3 and the 2nd equation by (-4) to get;
9B +12M = 17.01 ------(3)
-20B - 12M = -26.80 ------(3)
Add equations 3 and 4 together to get;
-11B = -9.79
B = 0.89
Plug this value for B in to the 1st equation and solve for M to get;
3(0.89) + 4M = 5.67
2.67 + 4M = 5.67
4M = 3.00
M = 0.75

The wholesale price of the TV will be 0.40 x where x represents the retail price.
Percentage :
In mathematics, it is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, "%"
Let the retail price of TV be x
Now, we are given that it is sold off at 60 percent discount.
Whole sale price = x - 60 % of x
Whole sale price = x - 60 / 100 x
Whole sale price = x - 0.60 x
Whole sale price = 0.40 x.
Therefore, the wholesale price of the TV will be 0.40 x where x represents the retail price of the TV.

14. y = -3x + 5.
15. y = -1/3x - 2.
16. y = 5/4x - 1/4.
17. y = 7/4x + 19/2.
What is a linear function?A linear function is modeled by the following rule:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, the change in y divided by the change in x.b is the y-intercept, which is the the value of y when the function crosses the x-axis, that is, when x = 0.The slope is also related with parallel and perpendicular lines, as follows:
If the lines are parallel, they have the same slope.If the lines are perpendicular, the multiplication of their slopes is of -1.In item 13, the line in slope-intercept form is:
y = 2x/3.
The line we want to find is parallel, hence it has the same slope, that is:
y = 2x/3 + b.
When x = -1, y = 2, hence:
2 = -2/3 + b
b = 8/3.
Hence the line is:
y = 2x/3 + 8/3.
For item 14, the line is perpendicular to:
y = 1/3x + 4.
Hence the slope is found as follows:
1/3m = -1
m = -3.
Then:
y = -3x + b.
When x = 0, y = 5, hence b = 5 and the line is:
y = -3x + 5.
For item 15, the line is perpendicular to:
y = 3x + 4.
Then the slope is found as follows:
3m = -1
m = -1/3.
Then:
y = -1/3x + b.
When x = 0, y = -2, hence b = -2 and the line is:
y = -1/3x - 2.
For item 16, the line is perpendicular to:
y = 4 - 4/5x.
Then the slope is found as follows:
-4m/5 = -1
m = 5/4.
Hence:
y = 5/4x + b.
When x = 1, y = 1, hence:
1 = 5/4 + b
b = -1/4.
Then the line is:
y = 5/4x - 1/4.
For item 17, the line is perpendicular to:
y = 13/7 - 4/7x
Then the slope is found as follows:
-4m/7 = -1
m = 7/4.
Hence:
y = 7/4x + b.
When x = -2, y = 6, hence:
6 = -14/4 + b
b = 19/2.
Hence the line is given by:
y = 7/4x + 19/2.

Find the (perpendicular) distance from the line given by the parametric equations
x(t)= -2-6t
y(t)= 1-3t
z(t)= -5+7t
to the point (-8,9,8)
Answer:
[tex]\sqrt{(-\frac{806}{94}+8)^2+(-\frac{215}{94}-9)^2+ (-\frac{251}{94}-8)^2}[/tex] Whatever this number may be
Step-by-step explanation:
The distance will be on the plane containing the point, and perpendicular to the line - which exists as long as the point doesn't sit on the line, but in that case our distance will simply be zero. Good news, since the line is given in parametric equation, the equation of the plane is easy to write by simply computing the dot product between the vector generating the line - or any multiple of it! - and the vector joining a random point x y z of the space with our given point, and setting it equal to zero. The equation of our plane is thus
[tex]6(x-(-8)) + 3(y-9) -7(z-8) = 0\\6(x+8)+3(y-9)-7(z-8)=0[/tex]
We could multiply now or later, doesn't matter, so let's wait. Now, we need to know when the line passes through the plane, so let's plug the (parametric) coordinate of the line and let's see for which value of t that happens:
[tex]6(-2-6t+8) +3(1-3t -9) -7(-5+7t-8) =0\\6(6-6t) -3(8+3t)+7(13-7t)=0\\36-36t-24-9t+91-49t = 0\\t=103/94[/tex]
Found this value of t, we can use it to find the coordinate of the point in common between the line and the plane:
[tex](-2-6\frac {103}{94};1-3\frac {103}{94}; -5+7\frac {103}{94}) = (-\frac{806}{94};-\frac{215}{94};-\frac{251}{94})[/tex]
At this point it's simply a matter of calculating the distance between two points in 3D space, given by the usual [tex]\sqrt{\Delta x^2+\Delta y^2+\Delta z^2}[/tex], whatever abomination of a number it might become:
[tex]\sqrt{(-\frac{806}{94}+8)^2+(-\frac{215}{94}-9)^2+ (-\frac{251}{94}-8)^2}[/tex]

Step-by-step explanation:
The minimum is the smallest value in a data set.
Ordering the data from least to greatest, we get:
1 2 3 5 6 7 9 11 12 13 14 16 17 19 20
So the minimum is 1
The first quartile (or lower quartile or 25th percentile) is the median of the bottom half of the numbers. So, to find the first quartile, we need to place the numbers in value order and find the bottom half.
Quartile 1 is 5,
1 2 3 5 6 7 9 11 12 13 14 16 17 19 20
The first half is
1 2 3 5 6 7 9, the median of these numbers is 5 so Quartile 1 = 5
The median is the middle number in a sorted list of numbers. So, to find the median, we need to place the numbers in value order and find the middle number.
The median is 7, 1 2 3 5 6 7 9 11 12 13 14 16 17 19 20
The third quartile (or upper quartile or 75th percentile) is the median of the second half of the numbers. So, to find the third quartile, we need to place the numbers in value order and find the upper half.
Quartile 3 is 16,
1 2 3 5 6 7 9 11 12 13 14 16 17 19 20
The upper half is
12 13 14 16 17 19 20, the median of these numbers is 16 so Quartile 3 = 16
The maximum is the greatest value in a data set.
Ordering the data from least to greatest, we get:
1 2 3 5 6 7 9 11 12 13 14 16 17 19 20
So, the maximum is 20.
