Anna enjoys dinner with her family at a restaurant in Washington, D.C. She leaves a 15% tip on the price of her meal. She also has to pay a 10% sales tax on her meal, which is calculated on the pre-tip amount. She spends a total of $27.50 for dinner, including tax and tip. What is the cost of her dinner without tax and tip? Show your work.
Answer:
$22
Step-by-step explanation:
tax and the tip increase the price paid for the meal
she paid 15 + 10 = 25% more than the price of her meal
p = original price
1.15 x p = 27,50
p = 27.50 / 1.15 = 22

A company rents out 18 food booths and 27 game booths at the county fair. The fee for a food booth is $50 plus $6 per day. The fee for a game booth is $65 plus $8 per day. The fair lasts for d days, and all the booths are rented for the entire time. Enter a simplified expression for the amount, in dollars, that the company is paid.
Answer:
$2655 + $324d
Step-by-step explanation:
total cost of a booth = fixed cost + (variable cost x number of days)
Fixed costs are costs that do not vary with output
Variable costs are costs that vary with production
cost of 18 food booths = 18(50 + 6d) = 900 + 108d
cost of 27 game booths = 27(65 + 8d) = 1755 + 216d
Add the total cost of the food and game booths together 900 + 1755 = 2655
108d + 216d = 324d

25 20 15 10 5 nth term
Answer:
-15
Step-by-step explanation:
Answer:
nth term = -5n + 30
Step-by-step explanation:
Given sequence:-
25 20 15 10 5
To find the nth term, we have to find the algebraic expression, Xn.
Xn = dn + b
Here, 'd' means the common difference and 'b' means 'first term -- common difference'
the common difference here is -5
So, b = 25 - (-5)
b = 25 + 5
b = 30
Xn = -5n + 30
Therefore, nth term equals -5n + 30

1.3. If Sara draws a red ball and DOES NOT RETURN it, and then she goes to draw a green
ball, is this considered a dependent or independent event?
Answer:
Dependent Event
Step-by-step explanation:
Assume that are 10 balls, such that:
[tex]Red = 6[/tex]
[tex]Green = 4[/tex]
If the balls are replaced after taken, the probability is:
[tex]Pr(Red) = 6/10[/tex]
[tex]Pr(Green) = 4/10[/tex]
This is referred to as independent event; because each selection do not affect the next or previous selection
However, if the balls are not replaced, the probability is:
[tex]Pr(Red) = 6/10[/tex]
[tex]Pr(Green) = 5/(10 - 1) = 5/9[/tex]
We subtracted 1 because there is a reduction in the number of balls when the red ball is not returned.
This is referred to as independent event; because a selection affects the next selection
Find the value of X. Round to the

Answer:
4.4in
Step-by-step explanation:
Answer:
x ≈ 4.4 in
Step-by-step explanation:
Using Pythagoras' identity in the right triangle
with legs 2.4 and (7.4 ÷ 2) = 3.7 , x is the hypotenuse, then
x² = 2.4² + 3.7² = 5.76 + 13.69 = 19.45 ( take square root of both sides )
x = [tex]\sqrt{19.45}[/tex] ≈ 4.4 in ( to the nearest tenth )

The mean age of 5 women in an office is 23 years old. The mean age of 3 men in an office is 24 years old. What is the mean age (nearest year) of all the people in the office?
Answer:
23
Step-by-step explanation:
Women total age = 5 x 23 = 115
Men total age = 3 x 24 = 72
The mean age of all the people
= (115+72)÷(8)
= 23.375
= 23 (nearest year)
The mean age (nearest year) of all the people in the office is 23
How to determine the mean age?The given parameters are:
5 women = 23 years
3 men = 24 years
Mean is calculated using:
[tex]\bar x = \frac{\sum fx}{\sum f}[/tex]
So, we have:
[tex]\bar x = \frac{23 * 5 + 24 * 3}{5 + 3}[/tex]
Evaluate the quotient
[tex]\bar x = 23[/tex]
Hence, the mean age (nearest year) of all the people in the office is 23

A statistician has analysed the duration of audience laughter after a stand up comedian's jokes. The data showed that the laughter duration was evenly distributed between 4 seconds and 9.7 seconds. Then, the probability that the laughter after one of this comedian's jokes lasts for more than 7 seconds is
Answer:
The probability that the laughter after one of the comedians jokes lasts for more than 7 seconds is approximately 0.474
Step-by-step explanation:
The nature of the distribution of the given data = Evenly distributed data
The range of the laughter times = Between 4 seconds and 9.7 seconds
The probability density function, f(x), is given as follows;
[tex]f(x) = \dfrac{1}{b - a}[/tex]
The mean of the uniform distribution, μ, is given as follows;
[tex]\mu = \dfrac{a + b}{2}[/tex]
The standard deviation, σ, is given as follows;
[tex]\sigma = \sqrt{\dfrac{\left (b - a\right)^2}{12} }[/tex]
Where;
a = 4, and b = 9.7, we have;
μ = (4 + 9.7)/2 = 6.85
σ = √((9.7 - 4)²/12) ≈ 1.64545
The probability density function, f(x) = 1/(b - a) for a ≤ x ≤ b
∴ f(x) = 1/(9.7 - 4)
For P(x > 7), we have;
P(x > 7) = 1 - P(x < 7) = 1 - (7 - 4) × 1/(9.7 - 4) ≈ 0.474
The probability that the laughter after one of the comedians jokes lasts for more than 7 seconds P(x >7) ≈ 0.474.

A function is described by the equation f(x) = 2x + 3. The replacement set for the independent variable is (2,4,6,8). Which set is the corresponding set for the dependent variable?
Write the values in the order shown. The curly braces indicate a set.
=================================================
Explanation:
The replacement set for the independent variable is {2,4,6,8}
This means we'll plug x = 2, x = 4, x = 6, and x = 8 into the function one at a time to find the corresponding y = f(x) value.
---------
Plug in x = 2 to find that,
f(x) = 2x+3
f(2) = 2*2+3 ... replace every x with 2
f(2) = 4+3
f(2) = 7
If the input is x = 2, then the output is y = 7. Therefore, the '2' in the domain corresponds to '7' in the range.
If you repeat those steps for x = 4, then you should find that f(4) = 11. Do the same thing for x = 6 and it should lead to y = 15. The last value in the range is y = 19 which corresponds to x = 8.
In short, the domain {2,4,6,8} corresponds to the range {7, 11, 15, 19}
Usually with sets, order doesn't matter. However, in this case, the order is important because we need to match the 2 with the 7, the 4 with the 11, etc.

In Triangle XYZ, measure of angle X = 49° , XY = 18°, and
YZ = 14°. Find the measure of angle Y.
Answer:
There are two choices for angle Y: [tex]Y \approx 54.987^{\circ}[/tex] for [tex]XZ \approx 15.193[/tex], [tex]Y \approx 27.008^{\circ}[/tex] for [tex]XZ \approx 8.424[/tex].
Step-by-step explanation:
There are mistakes in the statement, correct form is now described:
In triangle XYZ, measure of angle X = 49°, XY = 18 and YZ = 14. Find the measure of angle Y:
The line segment XY is opposite to angle Z and the line segment YZ is opposite to angle X. We can determine the length of the line segment XZ by the Law of Cosine:
[tex]YZ^{2} = XZ^{2} + XY^{2} -2\cdot XY\cdot XZ \cdot \cos X[/tex] (1)
If we know that [tex]X = 49^{\circ}[/tex], [tex]XY = 18[/tex] and [tex]YZ = 14[/tex], then we have the following second order polynomial:
[tex]14^{2} = XZ^{2} + 18^{2} - 2\cdot (18)\cdot XZ\cdot \cos 49^{\circ}[/tex]
[tex]XZ^{2}-23.618\cdot XZ +128 = 0[/tex] (2)
By the Quadratic Formula we have the following result:
[tex]XZ \approx 15.193\,\lor\,XZ \approx 8.424[/tex]
There are two possible triangles, we can determine the value of angle Y for each by the Law of Cosine again:
[tex]XZ^{2} = XY^{2} + YZ^{2} - 2\cdot XY \cdot YZ \cdot \cos Y[/tex]
[tex]\cos Y = \frac{XY^{2}+YZ^{2}-XZ^{2}}{2\cdot XY\cdot YZ}[/tex]
[tex]Y = \cos ^{-1}\left(\frac{XY^{2}+YZ^{2}-XZ^{2}}{2\cdot XY\cdot YZ} \right)[/tex]
1) [tex]XZ \approx 15.193[/tex]
[tex]Y = \cos^{-1}\left[\frac{18^{2}+14^{2}-15.193^{2}}{2\cdot (18)\cdot (14)} \right][/tex]
[tex]Y \approx 54.987^{\circ}[/tex]
2) [tex]XZ \approx 8.424[/tex]
[tex]Y = \cos^{-1}\left[\frac{18^{2}+14^{2}-8.424^{2}}{2\cdot (18)\cdot (14)} \right][/tex]
[tex]Y \approx 27.008^{\circ}[/tex]
There are two choices for angle Y: [tex]Y \approx 54.987^{\circ}[/tex] for [tex]XZ \approx 15.193[/tex], [tex]Y \approx 27.008^{\circ}[/tex] for [tex]XZ \approx 8.424[/tex].

1. Find the measure of arc ABC
110 °
Answer:
Arc ABC = 250°
Step-by-step explanation:
m<AOB = 110° (given)
Based on the central angle theorem, central angle m<AOB equals the intercepted arc AB
Therefore,
m<AOB = measure of arc AB = 110°
Thus:
Arc ABC = 360° - arc AB (Full circle = 360°)
Arc ABC = 360° - 110°
Arc ABC = 250°
