The mean increased, but the median remained constant If new dogs' weights are added to the data set.
What is the mean of a data set?The mean of a data set is defined as the ratio of the sum of observations to the total number of observations. It can be referred to as the average of a specific set of data or the arithmetic mean.
The formula for the mean of a given set of data is as follows:
Mean = Sum of Observations/Total number of observations
Given the set of observations as :
16, 34, 44, 20, 50, 19, 30, 54
Arrange the data in ascending order, we get
16, 19, 20, 30, 34, 44, 50, 54
The median of the given data would be (30+34)/2 = 32.
Here, n = 8
⇒ ∑x = Sum of Observations
⇒ ∑x = 267
Mean = ∑x/n
Mean = 267/8
Mean = 33.375
If two more dogs weighing 25 pounds and 45 pounds come to the kennel.
Arrange the given data in ascending order, we get
16, 19, 20, 25, 30, 34, 44, 45, 50, 54
The new median of the data would be (30+34)/2 = 32.
New mean = 337/10 = 33.7
Therefore, the mean increased, but the median remained constant If new dogs' weights are added to the data set.

A rock is dropped off the edge of a cliff and its distance s (in feet) from the top of the cliff after t seconds is s(t) = 16t2. Assume the distance from the top of the cliff to the water below is 96 ft.
A) When will the rock strike the water?
B) Make a table of average velocities and approximate the velocity at which the rock strikes the water.
Answer:
A) 2.45 seconds
B)[tex]\begin{center}\begin{tabular}{ c c}\bold{Average Velocity} & \bold{Velocity at strike of water} \\ 39.18 & 78.4 \\ \end{tabular}\end{center}[/tex]
Step-by-step explanation:
Distance [tex]s[/tex] (in feet) from the top of cliff after [tex]t[/tex] seconds when a rock is dropped off the edge of a cliff is given as:
[tex]s(t)=16t^2[/tex]
Distance from the top of cliff to water = 96 ft
To find:
A) When will the rock strike the water
i.e. The time taken by the rock to travel the distance of 96 ft.
B) Table of Average Velocity and approximate velocity at which the rock strikes the water ?
Solution:
A) Given that distance traveled = 96 ft
To find the value of [tex]t[/tex]
Putting the value of [tex]s[/tex] in formula: [tex]s(t)=16t^2[/tex] to find [tex]t[/tex]:
[tex]96 = 16t^2\\\Rightarrow t^2=6\\\Rightarrow \bold{t = 2.45\ sec}[/tex]
B) The velocity at which the rock hits the water:
We need to differentiate [tex]s(t)[/tex] w.r.to [tex]t[/tex] in order to find the velocity at any instant.
[tex]s'(t) =\dfrac{d}{dt}s(t) = \dfrac{d}{dt}(16t^2)\\\Rightarrow v = 2\times 16t^{(2-1)}\\\Rightarrow v = 32t[/tex]
The time taken to reach the water is 2.45 seconds.
Putting [tex]t[/tex] = 2.45 seconds to find the velocity:
[tex]v = 32\times 2.45 = 78.4\ ft/sec[/tex]
Average velocity is given as total distance traveled and total time taken.
[tex]\text{Average Velocity = }\dfrac{\text{Total Distance traveled}}{\text{Total Time Taken}}[/tex]
[tex]\text{Average Velocity = }\dfrac{96}{2.45}\\\text{Average Velocity = 39.18\ ft/s}[/tex]
[tex]\begin{center}\begin{tabular}{ c c}\bold{Average Velocity} & \bold{Velocity at strike of water} \\ 39.18 & 78.4 \\ \end{tabular}\end{center}[/tex]

You meet with the financial aid office to discuss your costs for attending MGA next semester. Tuition is $113.67 per credit hour, and fees are a flat cost of $660. You have a grant of $350 and a scholarship of $400. If you are taking 15 credit hours, what amount will you need to pay for your classes next semester?
Answer:
$1615.05
Step-by-step explanation:
First the cost. We know that tuition per credit hour is 113.67 and there is a flat fee of 660. This can be represented by 113.67h + 660, where h is equal to the number of credit hours.
Next, the amount paid. There are two constants of 350 and 400 already there. We can represent the remaining amount that needs to be paid by another variable, x.
Now, the cost needs to be equal to the amount you pay. We can replace h with 15 for 15 hours and solve for x.
113.67h + 660 = 350 + 400 + x
113.67(15) + 660 = 350 + 400 + x
1705.05 + 660 = 750 + x
2365.05 = 750 + x
1615.05 = x
How much of the circle is shaded? simply your answer
Answer:
The part that is shaded is 5/14
Step-by-step explanation:
The total circle is 1
1/2 + 1/7 + x = 1 where x is the shaded area
Multiply each side by 14 to get rid of the fractions
14(1/2 + 1/7 + x) = 1*14
7 + 2 + 14x = 14
9+14x = 14
Subtract 9 from each side
14x = 5
Divide by 14
x = 5/14
The part that is shaded is 5/14

y=-4x - 8
6x + 2y=-10
I need the equation solved by substitution
Please show work :)
Answer:
x =1.28571428571
Step-by-step explanation:
6x + 2y = -10
y = -4x - 8
6x + 2(4x - 8) = -10
6x + 8x - 8 = -10
14x - 8 = 10
(we put together the like terms)
14x = 10 + 8
14x = 18
x = [tex]\frac{18}{14}[/tex]
x = 1.28571428571

if a cubic container has a side length of 50.0cm, what is the volume in liter?
Answer:
The answer is
125 litresStep-by-step explanation:
To find the volume in liter we must first find the volume in cm³
Since the container is cubic
Volume = l³
where l is the length of one side
From the question
l = 50.0 cm
Volume = 50³
= 125000 cm³
Next we use the conversion
1cm³ = 0.001 L
If 1 cm³ = 0.001 L
Then 125,000 cm³ = 125,000 × 0.001 L
We have the final answer as
125 litresHope this helps you
Using the volume of a cube, and conversion of units, it is found that the volume of the cube is of 125 liters.
---------------------
The volume of a cube of side s is given by:
[tex]V = s^3[/tex]
---------------------
Side length of 50cm means that [tex]s = 50[/tex].Thus, the volume, in cubic centimetres, is given by:
[tex]V = 50^3 = 125000[/tex]
---------------------
To convert the volume from cubic centimetres to liters, it is divided by 1000.Then:
[tex]\frac{125000}{1000} = 125[/tex]
The volume of the cube is of 125 liters.
