The quartiles of rainfall in April for the city are:
Q1 = 1.96Q2 = 3.44Q3 = 4.79.What are the quartiles of rainfall?The quartiles refers to the e values that split sorted data into four parts each with an equal number of observations
To determine quartiles, we first need to sort the data in ascending order which are:
[tex]0.76, 1.08, 1.32, 1.55, 1.83, 2.09, 2.57, 2.83, 3.01, 3.25,\\3.63, 3.78, 4.09, 4.32, 4.64, 4.93, 5.23, 5.34, 5.44, 5.73[/tex]
There are 20 data points, so, median (Q2) will be the average of the 10th and 11th values.
Q2 = (3.25 + 3.63) / 2
Q2 = 3.44.
Q1 = (1.83 + 2.09) / 2
Q1 = 1.96.
Q3 = (4.64 + 4.93) / 2
Q3 = 4.79.

Using the MACRS rates from the following table, what is the book value of a $2,500 computer after 3 years? Ro Year MACRS Rate 1 2 3 4 5 20.0 % 32.0% 19.2% 11.52 % 11.52% book value = [?]
Using MACRS rates, the book value of the $2,500 computer after 3 years is $720.
What are MACRS rates?MACRS (Modified Accelerated Cost Recovery System) rates are prearranged percentages used for the purposes of tax.
They compute how much an asset depreciates each year based on its class and expected lifespan.
Using MACRS rates, we shall calculate the book value of a $2,500 computer after 3 years in this way.
First, we shall apply the respective depreciation rates to the initial cost and subtract the accumulated depreciation each year.
Year 1:
Depreciation = Year 1 MACRS Rate x Initial Cost
Depreciation = 20.0% × $2,500 = $500
Year 2:
Depreciation = Year 2 MACRS Rate x Initial Cost
Depreciation = 32.0% × $2,500 = $800
Year 3:
Depreciation = Year 3 MACRS Rate x Initial Cost
Depreciation = 19.2% × $2,500 = $480
Next, subtract the accumulated depreciation from the initial cost to have the book value for each year:
Year 1:
Book Value = Initial Cost - Depreciation
Book Value = $2,500 - $500 = $2,000
Year 2:
Book Value = Year 1 Book Value - Year 2 Depreciation
Book Value = $2,000 - $800 = $1,200
Year 3:
Book Value = Year 2 Book Value - Year 3 Depreciation
Book Value = $1,200 - $480 = $720
Therefore, the book value of the $2,500 computer after 3 years is $720.

If $22,000 is invested in an account earning 4.5% interest compounded continuously,
determine how long it will take the money to quadruple. Round to the nearest year.
Use the model A = Pet where A represents the future value of P dollars invested at
an interest rate r compounded continuously for t years.
OA) 31 years
B) 36 years
OC) 3 years
D) 308 years
Answer:
31 years
Step-by-step explanation:
A = P(interest rate)^number of years (n)
if the money is to quadruple, A = 4 X 22,000 = 88,000.
P = investment amount = 22,000.
interest rate is 4.5%. so we have the whole (100%) + 4.5% = 1.045%.
n is number of years.
22,000 (1.045)^n = 88, 000
divide both sides by 22, 000:
(1.045)^n = 4
take logs for both sides:
log (1.045)^n = log 4
simplify using log laws (by bringing down the n):
n log (1.045) = log 4
divide both sides by log (1.045):
n = (log 4) / log (1.045)
= 31.49 (31 years to nearest year)

Given that events A and B are independent with P(A) = 0.68 and
P(A and B) = 0.544, determine the value of P(B), rounding to the nearest
thousandth, if necessary.
The value of P (B) = 0.8
The probability of event A, P (A) = 0.68
The probability of events A and B, P (A ∩ B) = 0.544
The probability of event B, P (B) = ?
We know that Independent events are those where the probability of A event occurring doesn't affect the probability of B event. In other words, they don't depend upon each other and are independent.
By formula;
P (A ∩ B) = P (A) . P (B)
By substituting the values to the above equation, we get;
0.544= 0.68 * P (B)
P (B) = 0.8

Answer:
[tex](x-2)^2=-12(y+1)[/tex]
Step-by-step explanation:
From observation of the given diagram, we can see that the graphed conic section is a vertical parabola that opens downwards, with a vertex at (2, -1) and a focus at (2, -4).
The equation of a vertical parabola in standard form is:
[tex]\boxed{\begin{minipage}{5.8 cm}\underline{Standard form of a vertical parabola}\\\\$(x-h)^2=4p(y-k)$\\\\where:\\ \phantom{ww}$\bullet$ $p\neq 0$\\ \phantom{ww}$\bullet$ Vertex: \;$(h,k)$\\ \phantom{ww}$\bullet$ Focus:\; $(h,k + p)$\\\end{minipage}}[/tex]
Given the vertex is (2, -1):
[tex]h = 2[/tex][tex]k = -1[/tex]Given the formula for the focus is (h, k+p), then:
[tex]\begin{aligned}(h, k+p)&=(2, -4)\\(2,-1+p)&=(2,-4)\\\\\implies -1+p&=-4\\p&=-4+1\\p&=-3\end{aligned}[/tex]
To write the equation of the graphed conic section, substitute the found values of h, k and p into the standard formula:
[tex](x-2)^2=4(-3)(y-(-1))[/tex]
[tex](x-2)^2=-12(y+1)[/tex]
Therefore, the equation of the graphed conic section is:

In Austin TX the cost of housing for a family of four is $1600 per month. How much more would the family need to bring home annually in order to cover the cost of increased housing
The family would need to bring home an additional $2400 annually to cover the increased cost of housing.
The family would need to bring home annually to cover the cost of increased housing need to calculate the total cost of housing for a year and subtract the current annual cost of housing.
The current monthly cost of housing is $1600 so the annual cost is:
$1600/month x 12 months = $19,200/year
Let's assume the family needs to cover an increased housing cost of $200 per month.
The new monthly cost of housing would be:
$1600/month + $200/month = $1800/month
The new annual cost of housing would be:
$1800/month x 12 months = $21,600/year
The family would need to bring home annually to cover this increased cost need to subtract the current annual cost of housing from the new annual cost of housing:
$21,600/year - $19,200/year = $2400/year

3x° P (2x+45)° find the x value
Since angles M and P are complementary, if m∠M = 3x - 45 and m∠P = 2x + 15, the value of x is 24
and the value of M and P are 27° and 63° respectively.
Since M and P are complimentary, that means the sum of them is = 90°
So
3x - 45 + 2x + 15 = 90
Taking like terms
3x + 2x = 90 + 45 -15
5x = 120
x = 120/5
x = 24
to find M and P
since m∠M = 3x - 45
m = 3(24) -45
m = 27°
m∠P = 2x + 15

A survey of the people who like the films made in Nepali, English or Hindi languages reported that 50 liked Nepali, 40 liked English, 30 liked Hindi, 24 liked Nepali and 11 English, 19 liked Nepali and Hindi, 13 liked Hindi and English, 6 liked all three and people were found not intended in any films.
To solve this problem, we can use the formula:
Total = n(A) + n(B) + n(C) - n(A and B) - n(A and C) - n(B and C) + n(A and B and C)
where:
n(A) = number of people who liked Nepali
n(B) = number of people who liked English
n(C) = number of people who liked Hindi
n(A and B) = number of people who liked both Nepali and English
n(A and C) = number of people who liked both Nepali and Hindi
n(B and C) = number of people who liked both English and Hindi
n(A and B and C) = number of people who liked all three languages
From the given information in the problem, we have:
n(A) = 50
n(B) = 40
n(C) = 30
n(A and B) = 11
n(A and C) = 19
n(B and C) = 13
n(A and B and C) = 6
We can now substitute these values into the formula:
Total = 50 + 40 + 30 - 11 - 19 - 13 + 6
Total = 73

18 cm
The distance that the end of the pendulum travels when it swings is given by the relation D = 27.3 cm
Given data ,
A pendulum of length 18 cm is swinging from a fixed point
Now , it swings through an angle of 87°
So , Central Angle = ( s x 360° ) / 2πr
where s is the length of the arc
Now , D = ( θ/360 ) x 2πr
On simplifying , we get
D = ( 87 / 360 ) x 2 ( 3.14 ) ( 18 )
D = ( 0.241667 ) ( 113.04 )
D = 27.3 cm

A rectangle is a quadrilateral (a polygon with four sides) in which each angle is a right angle (90 degrees). It is a type of parallelogram in which opposite sides are parallel and congruent (equal in length). Rectangles have four sides and four vertices (corners).
The length of a rectangle is the distance between its two longer sides, while the width is the distance between its two shorter sides. The perimeter of a rectangle is the sum of the lengths of all its sides, while the area is the product of its length and width.
A golden rectangle has sides in the proportion of the golden ratio, which is approximately 1:1.618. Therefore, if the width is 30cm, the length can be found by multiplying 30 by 1.618.
