A car dealer recently sold five cars for the following profits 10, 126, 9,999, 12,398, 12,007, and 4,567. What was the mean for the profits of the sales
Answers
So, here is how to do it:
10,126 + 9,999 + 12,398 + 12,007 + 4,567 = 49,097
Now divide that number by 5 (the number of numbers):
49,097 / 5 = 9,819.4
The correct answer is 9,819.4

Answers
Note that 30 and 20 share the common factor 10. Multiplying 3 and 2 together produces 6. The LCD is 10*6 = 60. Note that both 30 and 20 divide into 60 with no remainder.
Then 19/30 = 2(19) / 2[30] = 38/60, and
13/20 = 3(13) / 3[20] = 39/60.
Which is larger, 38/60 or 39/60?
Write the relationship between these 2 numbers using the appropriate inequality operator.
Answer: [tex]\dfrac{38}{60}<\dfrac{39}{60}[/tex]
Step-by-step explanation:
The given fractions : [tex]\dfrac{19}{30}\text{ and }\dfrac{13}{20}[/tex]
The denominators of the above fraction : [tex]30, 20[/tex]
Least common multiple (LCM) of (30,20)=[tex]3\times2\times5\times2=60[/tex]
Multiply 2 to the numerator and denominator of [tex]\dfrac{19}{30}[/tex] and 3 to the numerator and denominator of [tex]\dfrac{13}{20}[/tex], we get
[tex]\dfrac{19\times2}{30\times2}=\dfrac{38}{60}[/tex]
[tex]\dfrac{13\times3}{20\times}=\dfrac{39}{60}[/tex]
Clearly , [tex]\dfrac{38}{60}<\dfrac{39}{60}[/tex]

What best describes the greatest height a ball will bounce off the ground after being dropped from a height of 50 centimeters? Less than 50 centimeters, as the ball transforms some of its thermal energy into sound energy Less than 50 centimeters, as the ball transforms some of its potential energy into sound energy Greater than 50 centimeters, as the ball transforms some of its thermal energy into potential energy Greater than 50 centimeters, as the ball transforms some of its potential energy into thermal energy
Answers
Less than 50 centimeters , as the ball transforms some of its potential energy into ound energy
Explanation:
When a ball is dropped from a height of 50 cm, several factors reduce the initial potential energy (PE) of the ball.
a. Between the time the ball is dropped and when it strikes the ground, aerodynamic frictional forces consume some of the PE.
b. When the ball hits the ground, the remaining PE is converted into kinetic energy (KE) as it strikes the surface.
c. The KE is dissipated by energy required to deform the ball, some of the KE is transformed into sound energy, and some of the KE is lost by frictional forces that generate heat (thermal energy).
d. The remaining energy is stored in the ball, and it causes the ball to rebound as if it was a wound spring with stored energy. The coefficient of restitution defines how much of the PE is stored for the rebound.
Answer:
B) Less than 50 centimeters , as the ball transforms some of its potential energy into sound energy
The function y_p(t) = \ln(1 + 2 t), \ t > -\frac{1}{2}, is a particular solution to the differential equation y^{\,\prime\prime} + 3 y = g(t). find g(t)
Answers
[tex]y_{p}(t) = ln(1 + 2t) - \frac{1}{2} [/tex]
The ODE is
y'' + 3y = g(t)
Obtain the derivatives of the particular solution.
[tex]y_{p}^{'} = \frac{2}{1+2t} \\\\ y_{p}^{''} = \frac{-4}{(1+2t)^{2}} [/tex]
Because the particular solution should satisfy the ODE, therefore
[tex]g(t)=- \frac{4}{(1+2t)^{2}} +3 \, ln(1+2t)- \frac{3}{2} [/tex]
Answer: [tex]g(t) = - \frac{4}{(1+2t)^{2}} + 3 \, ln(1+2t) - \frac{3}{2} [/tex]
Then
[tex][\ln{(1+2t)}]^{\prime\prime}+3[\ln{(1+2t)}]=g(t) \\ \\ \Rightarrow\bold{g(t)= \frac{2(1+6t)}{(1+2t)^2}+3\ln{(1+2t)}}[/tex]
A package of 10 cans of soup costs $14. An individual can costs $2. You need at least 25 cans. Find the price of each combination of items.You decide to buy 3 packages of 10 cans. How much do you pay for each can?
Answers
25×$2=$50 individual can cost
30×$2=$60, cost of cans individually bought
so the third problem would be the correct answer because it asks how much for each can
Answer:
$1.4
Step-by-step explanation:
Given, Price of a package of 10 cans = $14
and, Price of an individual can = $2
Now, if I have to purchase at least 25 cans their are two possible ways:
Purchasing 2 packages of the can and then purchase rest individual cans. Thus, if I have to purchase 25 cans it costs: 14 × 2 + 5 × 2 = $38.Purchasing 3 packages of cans. It will cost me: 3 × 14 = $42. But it will give me an extra 5 cans.
Further, if I decided to buy 3 packages of 10 cans it will cost me $42 and I will pay $1.4 for each can.
the costume designer decides to make the sashes a little smaller, so that each of the 8 dresses can have a sash. What fraction of fabric should the costume maker use to make each sash
Answers
The fraction that the costume maker should use for each sash is 1/8 of the total fabric available, as the fabric is being evenly divided among the 8 dresses.
Explanation:
If the costume designer is making sashes for 8 dresses and aims to use each bit of fabric equally, then each sash should consist of 1/8 of the total fabric. This is because the total fabric is being divided evenly among the 8 dresses. For example, if the costume designer has 8 yards of fabric, then each sash would use 1 yard of fabric (8 divided by 8 equals 1).
In fraction terms, each sash uses 1/8 of the fabric available. So for each dress, the costume designer should use 1/8 of the total fabric to make a sash.

What are the maximum data rates of 802.11 legacy, 802.11a, 802.11b, and 802.11g?
Answers
802.11a = 54 Mbps
802.11b = 11 Mbps
802.11g = 54 Mbps
The 802.11 standards designate maximum data rates: 802.11 legacy offers 2 Mbps, 802.11a and 802.11g both offer 54 Mbps, and 802.11b offers 11 Mbps. These maximum rates depend on ideal conditions and can be lower in real-world usage.
Explanation:The 802.11 wireless standards determine the maximum achievable data rates between a wireless device and a wireless access point. Here are the maximum data rates for the 802.11 legacy, 802.11a, 802.11b, and 802.11g:
802.11 legacy: The theoretical maximum speed is 2 Mbps.802.11a: It has a maximum data rate of 54 Mbps.802.11b: This standard allows for a maximum data rate of 11 Mbps.802.11g: This offers a maximum data rate of 54 Mbps, the same as 802.11a, but it is more widely compatible with other devices as it operates on the 2.4 GHz band.It's important to note that these are the maximum possible data rates, under ideal conditions. In real-world usage, the actual data rate can be lower due to factors such as distance from the access point, interference, and the number of devices connected to the network.

The length of a rectangle is five times its width. If the area of the rectangle is 125 m2 , find its perimeter.
Answers
W = width
L = 5W ---- Length is 5 times the width
A = LW= 125
first lets find L and W
A = LW = 125-----LW is the formula for area of a rectangle
we know L = 5W
we'll plug in 5W for L
A = (5W)W = 125
A = 5W^2 = 125
W^2 = 125/5
W^2 = 25
Take the squareroot
W = 5
L = 5W
L = 5 * 5
L = 25
P = Perimeter = 2(L + w) ----- formula for perimeter of a rectangle
P = 2(25 + 5)
P = 60

An electric current, I, in amps, is given by I=cos(wt)+√8sin(wt), where w≠0 is a constant. What are the maximum and minimum values of I
Answers
Final answer:
The maximum value of the electric current I is 1 + √8, and the minimum value is -1 - √8, found by considering the amplitudes of the cosine and sine components in the given function.
Explanation:
The maximum and minimum values of an electric current, I, can be found by analyzing the function I=cos(wt)+√8sin(wt), where w is a constant and ≠0.
To find the maximum and minimum values, we need to consider the amplitude of the sine and cosine components separately. The maximum amplitude of the cosine function is 1, and for the square root of 8 times the sine function, it is √8. Therefore, the maximum possible value of the current is when both the sine and cosine functions are at their peaks. In this case, the maximum value of I would be 1 + √8.
To find the minimum value, we consider the case when the cosine function is at its minimum value, -1, and the sine function is also at its minimum, which can also be - √8. Therefore, the minimum possible value of I would be -1 - √8.
