The best fit line is represented by the equation y = -0.632x + 27.1, where x
represents the total bill in dollars, and y represents the percentage of the
bill left as a tip.
a. What does the best fit line estimate for the percentage of the bill left as
a tip when the bill is $15? Is this reasonable?
b. What does the best fit line predict for the percentage of the bill left as a
tip when the bill is $50? Is this reasonable?

Answers

a) The estimate for the percentage of the bill left as a tip with a bill of $15 is of 17.62%, which is reasonable.

b) The estimate for the percentage of the bill left as a tip with a bill of $50 is a non-reasonable -4.5%.

What is the line of best fit?

The line of best fit in this problem is defined as follows:

y = -0.632x + 27.1.

In which the variables are defined as follows:

x is the total bill, in dollars.y is the percentage of the total bill left as a tip.

Hence, for a bill of $15, the estimate is found replacing x by 15, as follows:

y = -0.632(15) + 27.1 = 17.62%.

Which is reasonable, as it is a positive number.

For a bill of $50, the estimate is obtained as follows:

y = -0.632(50) + 27.1 = -4.5%.

Which is not reasonable, as it is a negative number.

c = f(a)

Now, in order to write a linear equation from the given table take any two values of the variables as,

a = 0 and c = 15, a = 4 and c = 8.

Then, the linear equation can be written as follows,

(c - 15)/(a - 0) = (15 - 8)/(0 - 4)

The value of R, given the equation, can be found to be $ 786. 99.

How to find the value of R?

To find the value of R, solve the operations in sequences:

First sequence:

= 0.052 / 4

= 0.013

Second sequence:

= ( 1 + 0. 052 / 4) ²⁴ - 1

= 0.363410670624455519270956581199

Solving for R then gives:

= 22,000 x ( 0.013 / 0.363410670624455519270956581199)

= $786.99

In conclusion, the value of R without rounding intermediate values when rounded to the nearest hundredth is $ 786. 99.

The equation of plane is x + 11y + 7z - 30 = 0

What is equation?

An equation is said to be a mathematical statement that proves two mathematical expressions are equal in algebra, and this is how it is most commonly used. In the equation 3x + 5 = 14, for example, the two expressions 3x + 5 and 14 are separated by the symbol "equal."

Let  ( x₁, y₁, z₁ ) ( x₂, y₂, z₂ ) ( x₃, y₃, z₃ ) be the coordinates,

we know that equation of plane is:

[tex]\left[\begin{array}{ccc}x-x1&y-y1&z-z1\\x2-x1&y2-y1&z2-z1\\x3-x1&y3-y1&z3-z1\end{array}\right][/tex] = 0

[tex]\left[\begin{array}{ccc}x+2&y-1&z-3\\0+2&4-1&8-3\\-1+2&-1-1&0-3\end{array}\right][/tex] = 0

[tex]\left[\begin{array}{ccc}x+2&y-1&z-3\\2&3&5\\1&-2&-3\end{array}\right][/tex] = 0

On solving this determinant,

(x+2) (-9+10) - (y-1) (-6-5) - (z-3) (-4-3) = 0

(x+2) - (y-1) (-11) - (z-3) (-7) = 0

x + 2 + 11y - 11 + 7z - 21 = 0

x + 11y + 7z - 30 = 0

By how many dollars does the total shipping cost increase if the weight increases by 1 pound?

A rate of change describes how one quantity changes in relation to another quantity. Mathematically, it is defined as the change in one divided by the change in the other quantity.

rate of change = change in  total shipping cost / change in weight

Using the  information in the table:

rate of change = 11-5 / 8-4 = 6/4 = 1.5

The value of n and m are 110 and 20 respectively if the equations are 2n + 3m = 280 and 2n + 5m = 320.

What is a linear equation?

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

It is given that:

Two linear equations are:

2n + 3m = 280

2n + 5m = 320

Using the elimination method:

Because the coefficient for n is the same in both equations

-2m = - 40

m = 20

n = 110

Thus, the value of n and m are 110 and 20 respectively if the equations   are 2n + 3m = 280 and 2n + 5m = 320.

Which expression represents (f-g)(x) according to the functions given?

It follows from the task content that the required function evaluation required is; (f -g)(x).

Given;

f(x) = 2x³ +5x² - 6x - 7

g(x)=2x-3

To find;

(f-g)(x).

Since; (f -g)(x) = f(x) - g(x), the resulting expression for (f -g)(x) is;

(f -g)(x) = 2x³ +5x² -6x -7 -2x +3

If cos of Ф = 2/5, find sin Ф/2 and cos Ф/2. Assume the angles are in the 1st quartile

Answers

The exact values of the sine and the cosine of the half angle are √(3 / 10) and √(7 / 10), respectively.

What are the exact values of two trigonometric functions?

Herein we know the exact value of the cosine of an angle set in the first quadrant. Then, the half angle is also in the first quadrant, whose sine and cosine are, respectively:

cos 0.5Ф > 0, sin 0.5Ф > 0

sin 0.5Ф = √[(1 - cos 0.5Ф) / 2]

cos 0.5Ф = √[(1 + cos 0.5Ф) / 2]

First, replace the values of the cosine of the half angle:

sin 0.5Ф = √[(1 - 2 / 5) / 2]

cos 0.5Ф = √[(1 + 2 / 5) / 2]

Second, simplify the resulting expression:

sin 0.5Ф = √[(1 - 2 / 5) / 2]

sin 0.5Ф = √[(3 / 5) / 2]

sin 0.5Ф = √(3 / 10)

cos 0.5Ф = √[(1 + 2 / 5) / 2]

cos 0.5Ф = √[(7 / 5) / 2]

cos 0.5Ф = √(7 / 10)

Answers

The percent increase of the profit is 15%

How to determine the percent increase of the profit?

In this question, the figures are given as

Profit in March = £2750

Profit in April = £3162.50

The percentage of the increase of the profit is then calculated using the following equation

Increase percentage = (Profit in April - Profit in March)/Profit in March * 100%

Substitute the known values in the above equation, so, we have the following representation

Increase percentage = (3162.50 - 2750)/2750 * 100%

write an equation for a line parallel to y = − 2 x − 3 and passing through the point (3,-3)

Answers

Equation of line parallel to y = − 2 x − 3 and passing through the point (3,-3) is y = -2x + 3.

When two lines are called parallel?

Two lines are parallel lines if they do not intersect.

The slopes of the lines are the same.

f(x)= mx + b and g(x)= nx + c are parallel if m = n.

According to the given question:

Given equation of line is y = −2x − 3

If the new line is parallel, then it will have the same slope.

y = -2x + b

Now this line passes through the point (x,y) = (3,-3) so put in the x and y values into the equation above, solve for b

-3 = -2(3) + b

b = 3

Answers

Answer:

a.  335°

Step-by-step explanation:

Bearing: The angle (in degrees) measured clockwise from north.

a.  The bearing from O to A

Measure the angle from the positive y-axis, clockwise to point A.

Angles on a straight line sum to 180°, so the angle between the negative x-axis and point A is (180° - 115°).

Bearing = 270° + (180° - 115°) = 335°

b.  The bearing from O to B

Measure the angle from the positive y-axis, clockwise to point B.

Bearing = 270° - 48° = 222°

c.  The bearing from O to C

Measure the angle from the positive y-axis, clockwise to point C.

Bearing = 180° - 27° = 153°

d.  The bearing from A to O

Measure the angle clockwise from north of point A to point O.

Bearing = 180° - 25° = 155°
