Use the box plots comparing the number of males and number of females attending the latest superhero movie each day for a month to answer the questions.

Part A: Estimate the IQR for the males' data. (2 points)

Part B: Estimate the difference between the median values of each data set. (2 points)

Part C: Describe the distribution of the data and if the mean or median would be a better measure of center for each. (4 points)

Part D: Provide a possible reason for the outlier in the data set. (2 points)

Answers

Answer:

Step-by-step explanation:

Part A:

The interquartile range is approximately 10

Part B:

The difference between the median values for each data set  is approximately 6

Part C:

i) More widely distributed and concentrated to the beginning of the month

The better measure of the center for the male dataset is the median

ii) The skewed distribution

The mean is the better measure of center for the dataset

Part D;

A possible reason for the outlier is by chance

Part A : The IQR for the male's data 25-2=23.

Part B : The difference between the median values of each data set 20-6=14

Part C : Because there are no outliers in the data, the mean would be a better estimate of center for Males.

Because the data has outliners, the meadian would be a better measure of center for females.

Part D : The females adore those particular movie stars and have a large group of pals with whom they may socialize whenever they want.

a) Show that the equation 2 x + 3 cos x + e^x = 0 has a root on the
interval (-1,0)
b) Use the Bisection method to find the solution of 2 x + 3 cos x +
e^x = 0. accurate with in 10-3. On (-1,0). (Use four digits-Rounding)

Answers

a) The equation has a root in the interval (-1,0)

b) The solution of [tex]2x+3cos(x)+e^{x}=0[/tex] by using the Bisection Method is x=0.9977 accurate within [tex]10^{-3}[/tex]

a) The intermediate zero theorem (Bolzano's Theorem) tells us that whenever you have a continuous function in a given interval and the extremes of the functions on this interval have oposite signs, then there must be a zero in between those extreme values.

A formal definition of this theorem is written like this:

"If a function f on the closed interval [a,b] is a continuous function and it holds that f(a)>0 and f(b)<0 or f(a)<0 and f(b)>0, then there is at least one x-value such that f(x)=0"

So basically we need to evaluate the given equation for both extremes of the interval x=-1 and x=0, if they return results opposite in sign, then there must be a zero in that interval, so let's evaluate the function for x=-1:

[tex]2x+3cos(x)+e^{x}[/tex]

[tex]2(-1)+3cos(-1)+e^{-1}=-0.0112[/tex]

Let's now test for x=0

[tex]2x+3cos(x)+e^{x}[/tex]

[tex]2(0)+3cos(0)+e^{0}=4[/tex]

So notice we ended up with two values -0.0112 and 4. One is positive and the other is negative, therefore there must be a zero in that interval.

b) The zero is located at x=-0.9977

The idea of the bisection method is to find values for x in the middle of two x-values that return opposite sign answers when evaluated on the given function. So we can start with the extremes of the given interval:

x=-1 and x=0

so we find the value in the middle by using the following formula:

[tex]mid-value=\frac{x_{1}+x_{2}}{2}[/tex]

so we get:

[tex]mid-value=\frac{-1+0}{2}[/tex]

mid-value=-0.5

Next, we evaluate the given function for that value:

[tex]2(-0.5)+3cos(-0.5)+e^{-0.5}=2.2393[/tex]

Since we got a positive answer, we now find the midpoint between -0.5 and -1 (which was the last x-value that returned a negative answer) so we get:

[tex]mid-value=\frac{-1-0.5}{2}[/tex]

mid-value=-0.75

Next, we evaluate the given function for that value:

[tex]2(-0.75)+3cos(-0.75)+e^{-0.75}=1.1674[/tex]

and we repeat the process until que get to the desired accuracy. I uploaded a table that has the corresponding iterations and its answers. There were 14 iterations done until we got to the final answer x=-0.9977.

Answer:

x = 134

Step-by-step explanation:

All right, I'm not the best at explaining these but I will try. So first these two are parallel lines (Because you can see the 2 arrows >> like this). When looking at the problem what I would first to is find the angle on the other side of 46, which is 134. Since these are parallel lines the line up there will also equal the same. So x would equal 134 and the angle on the other side will be 46. I hope that makes sense, if not you can ask me what doesn't make sense and I will try to explain it

Answer:

x = 134°

Step-by-step explanation:

x and 46° are same- side interior angles and sum to 180° , so

x + 46° = 180° ( subtract 46° from both sides )

x = 134°

Some plumbers charge a base rate plus an hourly rate for their services. The rates of two plumbers are shown in the table.


Base Rate Hourly Rate
Plumber A $35.00 $15.00
Plumber B $40.00 $12.00

To the nearest minute, at what amount of time does Plumber A become more expensive than Plumber B?

Answers

Hi! Plumber A - Base Rate = $35.00 and Hourly = $15.00
Plumber B - Base Rate = $40.00 and Hourly = $12.00

$35.00 + $15.00 + $15.00 = $65
$40.00 + 12.00 + $12.00 = $64

Plumber A become more expensive than Plumber B after two hours.

x = 1.67 hours is the nearest time when Plumer B becomes more expensive than plumber B.

What is the equation?

The equation is the relationship between variables and is represented as y = ax+b is an example of a polynomial equation.

Let the hours be x and the hourly rate is y.
Now the data given in the table is calibrated into the equation.
The equation for A,
y = 15x + 35    - - - - - (1)
The equation for B,
y = 12x + 40    - - - - - - (2)

Solving equations 1 and 2
15x + 35 = 12x + 40
3x = 5
x = 5/3
x = 1.67 hour
Now put it on equation 2 and equation 1
y(B) = 12 * 1.68 + 40
y (B)= $60.1
y(A) = 12 *1.68 + 35
y(A) = $60.2


Thus, x = 1.67 hours is the nearest time when Plumer B becomes more expensive than plumber B.
