45th percentile means that 45% of the data fall below that number while 55% (that is, 100-45) fall above it.

Now, arranging the number in ascending order;
$60, $85, $95, $105, $120, $145, $155, $175, $190, $215, $235, $240, $260, $285, $325

The total number of counts = 15
Then,
Index = 15*45% = 15*0.45 = 6.75

Round up,
Index = 7

The,
7th number = $155

Therefore, 45th percentile value of the data = $155

X'+7x=5cos(2t), x(0)=0
Digiron [165]
The ODE is linear. Multiplying both sides by e^{7t} allows you to condense the left hand side as the derivative of a product.

x'+7x=5\cos2t
e^{7t}x'+7e^{7t}x=5e^{7t}\cos2t
\dfrac{\mathrm d}{\mathrm dt}\left[e^{7t}x\right]=5e^{7t}\cos2t

Integrating both sides with respect to t yields

e^{7t}x=5\displaystyle\int e^{7t}\cos2t\,\mathrm dt

The integral can be done by parts. You should get

e^{7t}x=\dfrac5{53}e^{7t}(7\cos2t+2\sin2t)+C
x=\dfrac5{53}(7\cos2t+2\sin2t)+Ce^{-7t}

With the given initial condition, you have

0=\dfrac5{53}(7+0)+C\implies C=-\dfrac{35}{53}

So the particular solution to the ODE is

x=\dfrac5{53}(7\cos2t+2\sin2t)-\dfrac{35}{53}e^{-7t}

For a cube whole side lenght is 4 in , the expression 4 to the 3 could represent
S_A_V [24]

Answer:

Step-by-step explanation:

The volume of a cube.

The formula is V = s^3 where is the the "whole side length" of the cube. The cube requires three dimensions be multiplied together to find its volume.

That's why the formula is written as V = s^3. It means that V = s * s * s which is three sides multiplied together. They also need to be at right angles to each other.

Lisa [10]
The accumulated (future) value is given by the formula
F=P(1+i)^n
where 
P=amount of deposit (made at the beginning of the first period)
i=monthly interest, APR/12 = 3%/12 =0.0025
n=number of periods (month)

For example, the future value for the 6th month is
F(6)=1000(1.0025^6)=1015.09  (to the nearest cent)

Here is a schedule of the values,
i=month
F(i) = value at the end of month i.

  i   F(i)
 0  1000.0 
 1  1002.5 
 2  1005.01
 3  1007.52
 4  1010.04
 5  1012.56
 6  1015.09
 7  1017.63
 8  1020.18
 9  1022.73
10 1025.28
11 1027.85
12 1030.42 + $50 deposit = 1050.42
All values are rounded to the nearest cent.
