The average of a list of n numbers is 90. After the number 90n is added to the list , the average of list is 168. Find n?
Answer:
14
Step-by-step explanation:
[tex]\frac{90n+90n}{n+1}=168 \\ \\ 180n=168n+168 \\ \\ 12n=168 \\ \\ n=14[/tex]
Answer:
Step-by-step explanation:
Let the sum of the original list of n numbers be S. The average of the list is given by:
average = S/n
Since the average is 90, we can write:
90 = S/n
Multiplying both sides by n, we get:
90n = S
After the number 90n is added to the list, the average of the list becomes 168. The sum of the list is now S + 90n. The number of elements in the list is now n+1. The average of the list is given by:
average = (S + 90n) / (n+1)
Since the average is 168, we can write:
168 = (S + 90n) / (n+1)
Multiplying both sides by n+1, we get:
168(n+1) = S + 90n
Substituting for S using the equation S = 90n, we get:
168(n+1) = 90n + 90n
Simplifying, we get:
168n + 168 = 180n
Subtracting 168n from both sides, we get:
168 = 12n
Dividing both sides by 12, we get:
14 = n
Therefore, n = 14.

The area of the triangle is 22.4 cm². Calculate the length, b, of the longest side of the triangle.
The length, b, which is the longest side of the triangle, can be found to be 13.172 cm.
How to find the length ?To find the area of 22.4 cm², the formula used was:
Area = 1/2 x a x b x Sin(C)
Using this formula, we can find the value of side a to be :
22.4 = 1/2 x 3.7 x a x Sin(97°)
a = 12. 199 cm
We can then use the Cosine rule to find the value of b, which is the longest side:
b² = a² + c² - 2 x a x c x Cos(B)
b = √ ( a² + c² - 2 x a x c x Cos(B))
b = 13. 172 cm

Describe function.When looking at a graph, we use a procedure known as the Vertical Line Test to determine whether a function is actually a function. Simply drawing a vertical line will reveal whether the graph is a function if it touches it once. The graph is not a function if the vertical line is higher. A function is defined technically as a relationship between a set of possible outputs and a set of inputs, where each input is associated to exactly one outcome.
Given
Work is dependent on power.
Power is function on voltage.
Voltage is linear, according to the query, so:
V(t) = at + V

What are the coordinates of the point on the directed line segment from (-10, 2) to
(-3, -5) that partitions the segment into a ratio of 4 to 3?
Answer:
(-6, -2)
Step-by-step explanation:
For points A(-10, 2) and B(-3, -5), you want the point P that makes AP/PB = 4/3.
SetupUsing (x, y) for the coordinates of P, we have ...
AP/PB = 4/3
((x, y) -(-10, 2))/((-3, -5) -(x, y)) = 4/3
SolutionThis simplifies to ...
(x+10, y-2)/(-3-x, -5-y) = 4/3
Cross multiplying gives ...
3(x +10, y -2) = 4(-3 -x, -5 -y)
(3x+30, 3y-6) = (-12-4x, -20-4y)
Treating these equations separately, we have ...
3x +30 = -12 -4x ⇒ 7x = -42 ⇒ x = -6
3y -6 = -20 -4y ⇒ 7y = -14 ⇒ y = -2
The point that partitions the segment is (-6, -2).
__
Additional comment
The point that partitions AB in the ratio m/n is ...
P = (mB +nA)/(m+n)
P = (4(-3, -5) +3(-10, 2))/(4+3) = (-12-30, -20+6)/7 = (-42, -14)/7 = (-6, -2)
Above, we started from the basic requirement, rather than using the formula that results from that requirement.
4 adults took their 5 children to a movie. The price for the 9 people was $160. The 5 children recieved a 20% discount on their tickets. The cost for a child ticket is how much less than the cost of an adult ticket?
The cost for a child ticket was $4 less than the cost of an adult ticket.
What is an equation?An equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Let the cost of adult tickets be x.
The 5 children received a 20% discount on their tickets.
So;
x-20% of x
= (x-20/100) × x
= x-0.2x
= 0.8x
Here, 4x+5×0.8x=160
⇒ 4x+4x=160
⇒ 8x=160
⇒ x=20
So, the cost of children is 20-20% of 20
= 20-0.2×20
= 20-4
= 16
Therefore, the cost for a child ticket was $4 less than the cost of an adult ticket.

An experiment is carried out to determine the relationship between the average speed (rpm) and power (hp) of a mixer.
Construct a scatter plot for the data obtained in the experiment. Complete your work in the space provided or upload a
file that can display math symbols if your work requires it. Be sure to label the axes and include an appropriate scale for
the numerical labels.
Answer: The wording may be confusing, but the problem is simple.
All they are asking you to do is to plot those x-y value pairs as data points on a graph. Doing that is very basic to science. In science, you put your data on a chart and look at how it shapes up to draw conclusions.
So your first point has x=325.0 and y=1.10,
your second point has x=348.9 and y=1.40, and so on.
If using pencil and paper, your best bet is to use graphing paper, or at least grid paper. Then your first step would be setting up the scale on the axes. You need to fit points with y values between 0.25 and 1.40, so you may want to set the scale on the y-axis so it covers the range from 0 to 1.6 at least (maybe even 0 to 2). Your x values are between 230.0 and 348.9, so you could set up your x-axis so that it includes 0 to 360 (or 0 to 400). Alternatively, you may not include x values all the way down to zero and set your x scale from 200 to 360 only,
The conclusion that you would draw from your plot is that the power seems to vary linearly with speed. The data points are almost in a straight line. They are not perfectly aligned, of course. There is always some variability in accurate data, but you can see a trend. You could draw a line that seems to fit the points best and use it to predict that the power at 250 rpm would be 0.44 hp for example.

The vertices of A'B'C' are A, B, and C
(Simplify your answers. Type ordered pairs.)
The translated vertices from the given vertices are:
A(3, -4) → A'(-2, -6)
B(-4, -2) → B'(-9, -4)
C(1, 1) → C'(-4, -1)
What is the translation rule?The translation rule for the coordinates of a graph is given by
(x, y) → (x + a, y + b)
Here the coordinates (x, y) are translated by (a, b) units.
Calculation:The given vertices of a ΔABC are:
A(3, -4), B(-4, -2), and C(1, 1)
If the vertices are translated by T(-5, -2) units, then the new vertices after translation are calculated by using the rule (x, y) → (x + a, y + b). Here (a, b) is (-5, -2).
Thus,
A(3, -4) → (3 - 5, -4 - 2) ⇒ A'(-2, -6)
B(-4, -2) → (-4 - 5, -2 - 2) ⇒ B'(-9, -4)
C(1, 1) → (1 - 5, 1 - 2) ⇒ C'(-4, -1)
Therefore, the translated version of the ΔABC is ΔA'B'C' and its vertices are A'(-2, -6), B'(-9, -4), and C'(-4, -1).

Find the total displacement vector for this walk:
If this person walked straight home, they'd have to walk
miles
This person has walked a total of 21 miles and the total displacement vector for this walk is 13.153 in northeast direction by the concept of distance and displacement.
What is distance and displacement?Unaffected by direction, distance describes an object's entire movement. Displacement, in contrast, refers to a shift in an object's position. Because of this, the primary distinction between distance and displacement is that one is a scalar and the other is a vector.
According to question let us determine the total distance 2 miles+3 miles+6 miles+7 miles+3 miles =21 miles
So, this person has walked a total of 21 miles
Now let us find displacement vector as follows:
Divide into parts: Each leg on the Southeast and Southwest diagonals is the hypotenuse, therefore multiply by (2) /2.
x-axis is given as 2+3*(√ (2) /2) +0 -7(√ (2) /2) +3 =1.464
Similarly, y-axis is given as 0- 3(√ (2) /2)- 6- 7(√ (2) /2) +0=-13.071
The coordinates of the given ques are as follows: <1.464, -13.071>
By Pythagoras theorem, the hypotenuse of the given coordinates is 13.153 in northeast which is our required displacement.

A family of bears is going to a movie. The following data points represent the ticket and candy price (in dollars) for each bear. Sort the data from least to greatest. Find the interquartile range (IQR) of the data set.
The interquartile range (IQR) is a measure of dispersion, which is a measure of how spread out a data set is. The IQR is calculated by subtracting the first quartile (Q1) from the third quartile (Q3).
Q1 = ( n +1 ) / 4th observation
= ( 9 + 1) / 4
= 2.5 th obseravation
That is the average of 2nd and 3rd observations.
Q1 = 2
Q3 = 3 ( n + 1) / 4 th observation
= 3 ( 9 + 1) / 4
= 7.5 th observation
That is the average of the 7th and 8th observation
Q3 = 5.5
Interquartile range = Q3 - Q1 = 5.5 - 2 = 3.5
In this data set, the first quartile is the average of the second and third observations (2), and the third quartile is the average of the seventh and eighth observations (5.5). Subtracting the first quartile from the third quartile gives us an IQR of 3.5. This means that the values in the data set are spread out over a range of 3.5 dollars.
