[A] Write and solve a system of equations to represent the total cost, y, when x additional pieces are purchased with a basic cat tree at each store.
[B] Solve this system of equations and show your work.
[C] Reggie wants to purchase a cat tree for his pets. Based on your work, explain which store would be cheaper depending on how many add-ons he wants to purchase.
The system of equations to represent the total cost, y, when x additional pieces are purchased with a basic cat tree at each store are;
y = 50x + 100 ------(eq 1)
y = 75x + 50 ------(eq 2)
How to Solve Simultaneous Equations?A) Let the total cost of the cat tree be y
Let each additional piece added be x.
Since basic tree is $100 and each additional platform costs $50, then we can say that;
y = 50x + 100 ------(eq 1)
Now, their basic cat tree starts at $50 and each additional piece costs $75. Thus;
y = 75x + 50 ------(eq 2)
B) Subtract eq 1 from eq 2 to gte;
25x - 50 = 0
25x = 50
x = 50/25
x = 2
y = 75(2) - 50
y = $100
C) The Store that would be cheaper depending on the add - ons is Puuur Place because as x increases, it's y-value increases at a lesser rate than that of Meow.

Questions are from: Gerald and Wheatly, Applied Numerical Analysis 1) 10. A sky diver jumps from a plane, and during the time before the parachute opens, the air resistance is propor- tional to the power of the diver's velocity. If it is known that the maximum rate of fall under these condi- tions is 80 mph, determine the diver's velocity during the first 2 sec of fall using the modified Euler method with Ar= 0.2. Neglect horizontal drift and assume an initial velocity of zero.
The diver's velocity during the first 2 sec of fall using the modified Euler method with Ar= 0.2 is 62.732 mph.
Given data: Initial velocity, u = 0 ft/sec
Acceleration, a = g = 32.2 ft/sec²
The maximum rate of fall, vmax = 80 mph
Time, t = 2 seconds
Air resistance constant, Ar = 0.2
We are supposed to determine the sky diver's velocity during the first 2 seconds of fall using the modified Euler method.
The governing equation for the velocity of the skydiver is given by the following:
ma = -m * g + k * v²
where, m = mass of the skydive
r, g = acceleration due to gravity, k = air resistance constant, and v = velocity of the skydiver.
The equation can be written as,
v' = -g + (k / m) * v²
Here, v' = dv/dt = acceleration
Hence, the modified Euler's formula for the velocity can be written as
v1 = v0 + h * v'0.5 * (v'0 + v'1)
where, v0 = 0 ft/sec, h = 2 sec, and v'0 = -g + (k / m) * v0² = -g = -32.2 ft/sec²
As the initial velocity of the skydiver is zero, we can write
v1 = 0 + 2 * (-32.2 + (0.2 / 68.956) * 0²)0.5 * (-32.2 + (-32.2 + (0.2 / 68.956) * 0.5² * (-32.2 + (-32.2 + (0.2 / 68.956) * 0²)))
v1 = 62.732 mph
Therefore, the skydiver's velocity during the first 2 seconds of fall using the modified Euler method with Ar= 0.2 is 62.732 mph.

Create a list of 6 one digit whole numbers with an average of 5, a median of 6, a range of 9, and no mode.
A list of 6 one digit whole numbers with an average of 5, a median of 6, a range of 9, and no mode is
0, 1, 5, 7, 8, and 9How to create the listsince the numbers will have no mode so they are all different
Assuming the numbers are: a, b. c. d. e. and f
The average is 5
(a + b + c + d + e + f ) / 6 = 5
a + b + c + d + e + f = 30
The median is 6
(c + d)/2 = 6
c + d = 12 (assume c = 5 and d = 7)
range is 9
f - a = 9, since it is a one digit number a range of 9 is possible for 9 - 0
hence a = 0 and f = 9
substituting assumed values to the average
0 + b + 5 + 7 + e + 9 = 30
b + e + 21 = 30
b + e = 9 (let b = 8and e = 1)
hence the numbers are
0, 1, 5, 7, 8, and 9

a. regular fat cheese
b. LDL levels
c. reduced fat cheese
d. both a and b
e. both b and c
In the given study comparing the effects of regular-fat cheese to reduced-fat cheese on LDL cholesterol levels, the dependent variable(s) refers to the outcome(s) that are being measured or observed. In this case, the dependent variable in this study is: b. LDL levels
The dependent variable is the variable that is measured or observed to assess the effect of the independent variable(s). In this case, the study is comparing the effects of regular-fat cheese and reduced-fat cheese on LDL cholesterol levels.
LDL cholesterol levels are the outcome being measured to determine the impact of the different types of cheese on cholesterol. Therefore, option b, LDL levels, is the dependent variable in this study. Options a (regular fat cheese) and c (reduced fat cheese) are not the dependent variables but rather the independent variables, as they are the different conditions being compared to assess their effect on LDL levels.
Option d (both a and b) and option e (both b and c) are incorrect because regular-fat cheese (option a) is an independent variable, not a dependent variable.

a factory produces laptops, and 95% of the laptops produced are tested and found to be functional. 5% of the laptops produced are defective. given that a laptop is randomly selected, and it is functional, what is the probability that it was tested?
The probability that the laptop was tested, given that it is functional, is 0.95, or 95%.
Given that the laptop is usable, we need to assess the probability that it has been tested. Let T stand for the laptop's testing event and F stand for the laptop's functioning event. The probability of T given F is what we are looking for next, or P(T|F).
The Bayes theorem can be used to determine P(T|F):
P(T|F) = P(F|T) * P(T) / P(F)
where P(F|T) is the probability that a laptop will be tested (which is 0.95), P(T) is the likelihood that a laptop will be tested, and P(F) is the likelihood that a laptop will be functional (which is the total of the likelihoods of being functional and defective, i.e., 0.95 + 0.05 = 1).
Using the conditional probability formula, we can determine P(F|T):
P(F|T) = P(F and T) / P(T)
Since 95% of the laptops produced are tested and determined to be functional, we know that the probability of a laptop being functional and tested is 0.95.
Therefore:
P(F|T) = 0.95 / 0.95 = 1
Substituting into Bayes' theorem:
P(T|F) = 1 * 0.95 / 1 = 0.95
Therefore, the probability that the laptop was tested, given that it is functional, is 0.95, or 95%.

Use the proportion d / 180⁰ = r radian / π radians . Find the equivalent degree measure or radian measure.
10⁰
Given proportion is d / 180⁰ = r radian / π radians.The equivalent degree measure is 10° and the equivalent radian measure is 1/18 π radians.
To find the equivalent degree measure or radian measure of angle 10°.Let's substitute the given value of 10° in the above proportion, which can be written as; d / 180⁰ = r radian / π radians
On substituting, we get; d / 180⁰ = r / π (Here, d = 10°)
Multiplying both sides by 180°, we get; d = 180° * r / π
Therefore, the equivalent radian measure is; r = 10° * π / 180°= 1/18 π radians And, the equivalent degree measure is; d = 180r / π = (1/18 π) / π =10°
Therefore, the equivalent degree measure is 10° and the equivalent radian measure is 1/18 π radians.

The formula for wind chill C (in degrees Fahrenheit) is given by C = 35. 74 + 0. 6215T − 35. 75v0. 16 + 0. 4275Tv0. 16 where v is the wind speed in miles per hour and T is the temperature in degrees Fahrenheit. The wind speed is 21 ± 3 miles per hour and the temperature is 8° ± 3°. Use dC to estimate the maximum possible propagated error (round your answer to four decimal places) and relative error in calculating the wind chill (round your answer to two decimal places). † dC = __________. ° dC/ C =_________
The maximum possible propagated error in calculating the wind chill is approximately 34.2045 degrees Fahrenheit , and the relative error in calculating the wind chill is approximately -5.89%
To estimate the maximum possible propagated error, we will use the formula:
dC = sqrt((∂C/∂T)^2 * dT^2 + (∂C/∂v)^2 * dv^2)
where ∂C/∂T and ∂C/∂v are the partial derivatives of C with respect to T and v, respectively, and dT and dv are the uncertainties in T and v, respectively.
Taking the partial derivatives of C, we get:
∂C/∂T = 0.6215 + 0.4275v^0.16
∂C/∂v = -9.424v^0.84/(25T^0.16)
Substituting the given values and uncertainties, we get:
T = 8 ± 3
v = 21 ± 3
dT = 3
dv = 3
∂C/∂T = 0.6215 + 0.4275(21)^0.16 ≈ 1.1398
∂C/∂v = -9.424(21)^0.84/(25(8)^0.16) ≈ -11.2782
dC = sqrt((1.1398)^2 × (3)^2 + (-11.2782)^2 × (3)^2) ≈ 34.2045
Therefore, the maximum possible propagated error in calculating the wind chill is approximately 34.2045 degrees Fahrenheit.
To estimate the relative error, we will use the formula:
dC/C = (dC/C)T + (dC/C)v
where (dC/C)T and (dC/C)v are the relative errors due to T and v, respectively.
Taking the partial derivatives of C, we get:
∂C/∂T = 0.6215 + 0.4275v^0.16
∂C/∂v = -9.424v^0.84/(25T^0.16)
Substitute the given values and uncertainties, we get:
T = 8 ± 3
v = 21 ± 3
dT = 3
dv = 3
∂C/∂T = 0.6215 + 0.4275(21)^0.16 ≈ 1.1398
∂C/∂v = -9.424(21)^0.84/(25(8)^0.16) ≈ -11.2782
(dC/C)T = (∂C/∂T × dT)/C ≈ (1.1398 × 3)/(35.74 + 0.6215(8) - 35.75(21)^0.16 + 0.4275(8)(21)^0.16) ≈ 0.0066
(dC/C)v = (∂C/∂v × dv)/C ≈ (-11.2782 × 3)/(35.74 + 0.6215(8) - 35.75(21)^0.16 + 0.4275(8)(21)^0.16) ≈ -0.0655
Therefore, the relative error in calculating the wind chill is approximately -0.0589 or -5.89%

The scale factor of two similar polygons is given. Find the ratio of their perimeters and the ratios of their areas.
1) 3:1
2) 7/4
The ratios of their perimeters and the ratios of their areas are 1) 3:1 and 9:1 and 2) 7:4 and 49:16.
Given the scale factor of two similar polygons, we need to find the ratio of their perimeters and the ratios of their areas,
To find the ratio of the perimeters of two similar polygons, we can simply write the scale factor as it is because the ratio of the perimeter is equal to the ration of the corresponding lengths.
1) So, perimeter = 3:1
The ratio of areas between two similar polygons is equal to the square of the scale factor.
Since the scale factor is 3:1, the ratio of their areas is:
(Ratio of areas) = (Scale factor)² = 9/1 = 9:1
Similarly,
2) Perimeter = 7:4
Area = 49/16
Hence the ratios of their perimeters and the ratios of their areas are 1) 3:1 and 9:1 and 2) 7:4 and 49:16.
