1: 5
2: 244

To find the mean add up all the numbers so
: 2+2+5+6+8+4+8+5=40. The divide by the amount of numbers there are 8 numbers so 40/8=5.
To find the median just put the numbers in order
131,154,204,207,244,244,263,274,276,288,289
then cross them out until your in the middle
So 244

People who said yes: $24-18=6$

Decimal: $\frac{6}{24} = \frac{6/6}{24/4} = \frac{1}{4} =0.25$

Percentage: $0.25*100=25$ --> 25%

A ladder leans against a building forming an angle of 50° with the ground. The base of the ladder is 8 feet from the building. W

Aleksandr-060686 [28]

Answer:

The correct answer is 12.446 feet.

Step-by-step explanation:

A ladder leans against a building forming an angle of 50° with the ground.

The base of the given ladder is 8 feet away from the building.

Let the length of the ladder that is to be found be x feet.

Thus we find the cosine of the angle of inclination.

∴ cos 50° = $\frac{8}{x}$

⇒ x = 12.446 feet

Therefore the length of the ladder is 12.446 feet.

Given an exponential function for compounding interest, A(x)=P(1.02)^x, what is the rate of change?

Rudiy27

$\bf \qquad \textit{Amount for Exponential Growth}\\\\
A=I(1 + r)^t\qquad 
\begin{cases}
A=\textit{accumulated amount}\\
I=\textit{initial amount}\\
r=rate\to r\%\to \frac{r}{100}\\
t=\textit{elapsed time}\\
\end{cases}\\\\
-------------------------------\\\\
\stackrel{A}{A(x)}=\stackrel{I}{P}(1.02)^{\stackrel{t}{x}}\implies A=P(1+\stackrel{r}{0.02})^x\implies \cfrac{r}{100}=0.02
\\\\\\
r=100\cdot 0.02\implies r=\stackrel{\%}{2}$

First angle in the triangle is 52 degrees Celsius and I need to find the outside and top

Margaret [11]

In figure,

AC = BC (given)

Since, in a triangle , angles opposite to equal sides are also equal.

Therefore,

b= 52°

Now,

°.° c is exterior angle of triangle.

.°. c = b + 52°

=> c = 52° + 52°

=> c = 104°

Solution:-

-------------

b = 52° & c =104°
