Answer: The difference between the mean cost to treat dogs at A New Leash on Life
Animal Clinic and the mean cost to treat cats at A New Leash on Life Animal
Clinic is about 10 times the MAD This is a large difference.
Step-by-step explanation:
I GOT THIS RIGHT! THIS IS THE ANSWER
The differences in mean costs to treat dogs and cats compared to the MAD at A New Leash on Life Animal Clinic suggest different levels of variability in the data. A 19 times difference labeled as 'moderate' implies high variability, while if labeled as 'large', the implication is that the variability is lower.
Explanation:The question relates to the comparison of the mean costs to treat dogs and cats at A New Leash on Life Animal Clinic, using the Mean Absolute Deviation (MAD) as a measure of variability. When we say that the difference between the mean cost to treat dogs and cats is about 19 times the MAD, and that this is a moderate difference, it suggests that the variability within each of the distributions is quite high, making a 19-fold difference in means seem less extreme. Conversely, the same difference being described as a large difference implies that the variability (MAD) is comparatively lower, hence a difference of the same scale appears more substantial relative to the spread of the data. This provides insight into the differences in treatment costs and the consistency of those costs within each group of animals.

Scott runs 4 sprints of 20 yards each. If he continues his routine, how many practices will it take for Scott to have sprinted a total of 2 miles combined?
Answers
Answer:
It will take 44 practices for Scott to have sprinted a total of 2 miles combined
Step-by-step explanation:
This question can be solved using rules of three.
First step:
Scott practice is measured in yards.
We want to know how many practices it will take for him to have sprinted 2 miles.
So we pass 2 miles to yards
Each mile has 1760 yards.
So 2 miles is 1760*2 = 3520 yards.
A practice:
4 sprints of 20 yards each.
So 4*20 = 80 yards.
A practice is 80 yards. How many practices for 3520 yards?
1 practice - 80 yards
x practices - 3520 yards
80x = 3520
x = 3520/80
x = 44
It will take 44 practices for Scott to have sprinted a total of 2 miles combined
The number of tickets purchased by an individual for Beckham College's holiday music festival is a uniformly distributed random variable ranging from 2 to 7. Find the mean and standard deviation of this random variable. (Round your answers to 2 decimal places.) Mean Standard deviation
Answers
Answer:
The mean is 4.5 and the standard deviation is 1.44.
Step-by-step explanation:
An uniform probability is a case of probability in which each outcome is equally as likely.
For this situation, we have a lower limit of the distribution that we call a and an upper limit that we call b.
The mean of the uniform probability distribution is:
[tex]M = \frac{(a + b)}{2}[/tex]
The standard deviation of the uniform probability distribution is:
[tex]S = \sqrt{\frac{(b-a)^{2}}{12}}[/tex]
Uniformly distributed random variable ranging from 2 to 7.
This means that [tex]a = 2, b = 7[/tex].
So
[tex]M = \frac{(2 + 7)}{2} = 4.5[/tex]
[tex]S = \sqrt{\frac{(b-a)^{2}}{12}} = \sqrt{\frac{(7 - 2)^{2}}{12}} = 1.44[/tex]
The mean is 4.5 and the standard deviation is 1.44.

2/3 is slope.
y=2/3x+-___
substitute in -3 from first point
y=-2+__=-2
y=2/3x+0
y=2/3x
Answer:
y + 2 = (3/2) (x+3) (point slope form)
Step-by-step explanation:
(see attached for reference)
Given
(x₁, y₁) = (-3,-2)
(x₂, y₂) = (1,4)
Since we are given 2 points, it would be easiest to express the equation of the line in point-slope form (see attached)
(y - y₁) = m (x - x₁)
we already have the values for x₁ and y₁, hence we only need to find the slope m (see 2nd attached graphic)
m = (y₂-y₁) / (x₂ - x₁)
= [4 - (-2) ] / [1 - (-3)]
= (4+2) / (1+3)
= 6/4
= 3/2
substituting the value for m and the values for x₁ and y₁:
(y - y₁) = m (x - x₁)
[y - (-2)] = (3/2) [x - (-3)]
y + 2 = (3/2) (x+3)

If (− 4, −8) and (−10, −12) are the endpoints of a diameter of a circle, what is the equation of the circle?
A) (x + 7)^2 + (y + 10)^2 = 13
B) (x + 7)^2 + (y − 10)^2 = 12
C) (x − 7)^2 + (y − 10)^2 = 169
D) (x − 13)^2 + (y − 10)^2 = 13
Answers
Answer:
Correct option: A
(x + 7)^2 + (y + 10)^2 = 13
Step-by-step explanation:
First we need to find the center of the circle. We can find it calculating the midpoint of the diameter.
the x-coordinates of the diameter are -4 and -10, so the midpoint is:
(-4 -10)/2 = -7
the y-coordinates of the diameter are --8 and -12, so the midpoint is:
(-8 -12)/2 = -10
Now we need to find the radius of the circle, so we find the diameter and then find half of it.
The lenght of the diameter is the distance of the endpoints:
D = sqrt((-4+10)^2 + (-8+12)^2) = 7.21
radius = 7.21/2 = 3.605
The generic equation of the circle is:
(x - xc)^2 + (y - yc)^2 = r^2
So we have:
(x + 7)^2 + (y + 10)^2 = 13
Correct option: A

A sphere has a diameter of 36 meters. What its exact volume?
Answers
Answer:
V = 7776 pi m^3
Step-by-step explanation:
The volume of a sphere is given by
V = 4/3 pi r^3
We need to know the radius
r = d/2 = 36/2 = 18
V = 4/3 pi (18)^3
V = 4/3 * pi *5832
V = 7776 pi
We cannot approximate pi since we want the exact answer
Answer:
7776π cubic meters.
Step-by-step explanation:
Recall the volume formula for a sphere is
V = (4/3) π r^3
r = (1/2)*diameter = (1/2)*36 m = 18 meters
V = (4/3)*π*(18)^3 = 24,429.02447 cubic meters
However the problem wants an exact answer, and not an approximation, therefore I will express the volume in terms of simplified expressions.
V = (4/3)*π*(18)^3 = (4/3)*π * (3*6)^3 = 4 *π * (1/3)*(3^3) *(6^3)
V = 4 *π * (1/3)*(3^3) *(6^3) = 4*π * 9 * 6^3 = 7776π cubic meters.

Step-by-step explanation:
Given:
Study Average hrs =2.1 =2.1 *60=126 minutes
For sample mean =1.8 *60= 108 minutes
S.D=20 and n=50
To Find:
True mean population distraction time with 90% confidence,
Solution:
90% C.I. means 90 % will fall in true mean and other will not .
So for that calculating the
Standard error=S.D/Sqrt(n)
S.E=20/Sqrt(50)
S.E=2.828
For 90% Confidence interval Z=1.65
C.I= mean±Z*Standard error
C.I=108±1.65*2.828
C.I=108±4.662
Hence C.I will range from 103.34 to 112.66
Study mean =126 minutes .
Here it ranges from 103.34 to 112.66
In this exercise we have to use the knowledge of probability to calculate this we will use percentage as:

The diagram shows two different buttons and their weights.

8 grams
c)
How many of each type of button are in the box?
Answers
To solve this problem, set up a system of equations with x and y representing the number of buttons. If there are 20 Weights of buttons in total, 20 of them weigh 12 grams and none weigh 8 grams.
To solve this problem, we can set up a system of equations. Let x be the number of buttons weighing 12 grams, and y be the number of buttons weighing 8 grams.
We can then write the following equations based on the information given:
x + y = total number of buttons
12x + 8y = total weight of the buttons
Substituting the given values, we have:
x + y = total number of buttons
12x + 8y = 240
From the first equation, we can express y in terms of x:
y = total number of buttons - x
Substituting this into the second equation:
12x + 8(total number of buttons - x) = 240
Simplifying:
12x + 8total number of buttons - 8x = 240
4x + 8total number of buttons = 240
4x = 240 - 8total number of buttons
4x = 8(30 - total number of buttons)
x = 2(30 - total number of buttons)
Since x and y represent the number of buttons, they must be whole numbers.
We can test different values for the total number of buttons to find a solution that satisfies this condition.
For example, if we assume there are 20 buttons in total:
x = 2(30 - 20) = 2(10) = 20
y = 20 - 20 = 0
Therefore, if there are 20 buttons in total, 20 of them weigh 12 grams and none weigh 8 grams.

Leila, Charlie, and Joe have a total of $144 in their wallets. Joe has 4 times what Leila has. Charlie has $6 more than Leila. How much does each have?
Answers
Answer:
The amounts of money each has are:
Joe = $92
Charlie = $29
Leila = $23
Step-by-step explanation:
To solve this, we will convert the statements into an equation, and use that to solve for the unknowns, as follows:
total amount = $144
Let Leila's share be S
Joe's share = 4 times Leila's = 4S
Charlie's share = $6 + Leila's share = 6 + S
Joe's share + Charlie's Share + Leila's Share = $144
4S + (6 + S) + S = 144
4S + 6 + S + S = 144
4S + 2S + 6 = 144
6S + 6 = 144
6S = 144 - 6 = 138
S = 138 ÷ 6 = $23
Therefore Leila's share 'S' = $23
Joe share= 4S = 4 × 23 = $92
Charlie's share = 6 + 23 = $29

A graph creates a triangle with the x-axis, the line 3x-2y=0, and the line x+2y=10. Find the area of the triangle formed in square units.
Answers
Answer:
18.75
Step-by-step explanation:
To identify the vertices of this triangle, you need to find the x intercepts of both lines, as where their solutions match. Let's start with setting them equal to each other. If you subtract 10 from both sides of the second equation, then both equations are left equaling zero. You can also multiply both sides of the equation by -1 for easier solving later Now:
3x-2y=-2y-x+10
4x=10
x=2.5
y=3.75
This shows that the height of this triangle is 3.75. Now, to find the x intercepts of both equations, we simply have to plug in the y value as 0. For the first one, 3x-0=0, so x=0 as well and the coordinates are (0,0). For the second one, x+0=10, so x=10 and the coordinates are (10,0). This shows that the base is 10-0=10 units long. The formula for the area of a triangle is [tex]\frac{bh}{2}=\frac{10\cdot3.75}{2}=18.75[/tex]. Hope this helps!

Jim needs to rent a car. A rental company charges $21 per day to rent a car and $0.10 for every mile driven. He will travel 250 miles and has $115 to spend. Write an inequality that can be used to determine the maximum number of DAYS that Jim can rent a car?
Answers
Final answer:
To determine the maximum number of days Jim can rent a car, set up the inequality 21d + 25 ≤ 115. Solving for 'd', Jim can rent a car for a maximum of 4 days.
Explanation:
To determine the maximum number of days that Jim can rent a car, we need to set up an inequality using the given information. Let's denote the number of days as 'd'. The rental cost per day is $21, so the total cost for 'd' days would be 21d. The cost for the miles driven is $0.10 per mile, and Jim will travel 250 miles. So the cost for the miles driven would be 0.10 * 250 = $25. Now, we can set up the inequality:
21d + 25 ≤ 115
To solve for 'd', we need to subtract 25 from both sides of the inequality:
21d ≤ 90
Now, divide both sides of the inequality by 21:
d ≤ 90/21
d ≤ 4.29 (approx)
So, Jim can rent a car for a maximum of 4 days.

Bill's golf bag contains 9 white golf balls, 6 yellow golf balls, 1 orange golf ball, and 1 pink golf ball. Without looking, Tim is going to take 1 golf ball out of his bag to tee off with and a different golf ball out to putt with. What is the probability of Tim teeing off with a white ball and putting with an orange ball? P(white, then orange) Are the events above independent or dependent events?
Answers
Final answer:
The probability of Tim teeing off with a white ball and putting with an orange ball is 0.0331. The events are dependent.
Explanation:
To calculate the probability of Tim teeing off with a white ball and putting with an orange ball, we need to consider the total number of balls in the bag and the number of white and orange balls.
There are a total of 9 white balls, 6 yellow balls, 1 orange ball, and 1 pink ball in the bag. The probability of Tim teeing off with a white ball is 9 out of 17, since he can choose any of the 9 white balls out of the total 17 balls. After Tim tees off with a white ball, there are now 8 white balls left in the bag.
Next, Tim needs to putt with an orange ball. The probability of Tim putting with an orange ball is 1 out of 16, since there is 1 orange ball left in the bag and a total of 16 balls.
To find the probability of both events happening, we multiply the two probabilities:
P(white, then orange) = P(white) × P(orange|white) = 9/17 × 1/16 = 9/272 = 0.0331 (rounded to four decimal places).
The events of teeing off with a white ball and putting with an orange ball are dependent events, as the outcome of the first event affects the probability of the second event.

The work done by a force on an object is given as the product of the force applied on the object and the distance moved by the object.
Mathematically:
W = F * d
The force applied by the man is 150 N and the distance moved is 20 m. Hence, the work done by the man is:
W = 150 * 20 = 3000 J
The work done by the man is 3000 Joules.
