Answer: 33.3%

Step-by-step explanation:

From the given table, the number of books which is a nonfiction paperback =23

The total number of books = 69

Then the probability that a randomly selected book is a nonfiction paperback is given by :-

\text{P( nonfiction paperback)}=\frac{23}{69}=0.33333....

In percent, \text{P( nonfiction paperback)}=0.33333.....\times33.333\%\approx=33.3\%

Hence, the probability that a randomly selected book is a nonfiction paperback is 33.3%

We have given the 2 by 2 frequency table.

The probability that a randomly selected book is a nonfiction paperback =

(Number of nonfiction paperback books) / Total number of books

= 23 / 69

= 0.3333

The percentage of nonfiction paperback books is 33.33%

Multiplying two digits<br>​
Vika [28.1K]

Answer:

Get a calculator

Step-by-step explanation:

Most of the time for simple math like multiplying 2 digits, it is easiest if you just get a calculator. It saves a lot of time.

If you can't get a calculator then i recommend memorizing some common equations.

For example 10*15= 150

so that if you get 12*15=?, you can easily just add two extra 15's to your answer of 150.

15+15 is 30, and 30+150(from 10*15)=180.

Therefore 12*15=180.

:) Hope that helped!

Find the general solution of the differential equation y^(5) −2y^(4) + y^(3) = 0.
Gwar [14]

y^{(5)}-2y^{(4)}+y^{(3)}=0

We can reduce the order of the ODE by substituting v(x)=y^{(3)}(x), so that v'(x)=y^{(4)}(x) and v''(x)=y^{(5)}(x). Then

v''-2v'+v=0

has characteristic equation

r^2-2r+1=(r-1)^2=0

with root r=1, which has multiplicity 2, so that the characteristic solution is

v_c=C_1e^x+C_2xe^x

Integrate both sides to solve for y''(x):

y''=C_1e^x+C_2e^x(x-1)+C_3

y''=C_1e^x+C_2xe^x+C_3

Integrate again to solve for y'(x):

y'=C_1e^x+C_2e^x(x-1)+C_3x+C_4

y'=C_1e^x+C_2xe^x+C_3x+C_4

And one last time to solve for y(x):

y=C_1e^x+C_2e^x(x-1)+\dfrac{C_3}2x^2+C_4x+C_5

\boxed{y(x)=C_1e^x+C_2e^x+C_3x^2+C_4x+C_5}

C negative higher you go the colder it gets which means dropping temps and then at some points it starts to snow at the top.
