Answer:

153.94

Step-by-step explanation:

The formula for the area of a circle is

A = $\pi r^{2}$

If the diameter is 14 in the to get the radius all you have to do is divide it by 2 to get 7

R is radius

R = 7

plug in 7 for R in the equation

$\pi$ * $7^{2}$

and you will get 153.94

Answer:

8x + 8y

8 (x +y)

Step-by-step explanation:

When adding or subtracting, the terms should have exact variables like x.

3x + 5x + 8y

Here 3 and 5 have the same variable x so you can add them. (3+5=8)

8x + 8y

Now take out common number (here it's 8):

Oxana [17]

Answer:

A. $\left[\begin{array}{cc}0.93&0.07&\\0.01&0.99&\end{array}\right]$

B. (0.85 0.15)

C. 79.2% population in the city while 20.8% population in the suburb

Step-by-step explanation:

(a) The transition matrix for the information is

C S

$\left[\begin{array}{cc}0.93&0.07&\\0.01&0.99&\end{array}\right]$

(b) the probability vector for the information is

$(\frac{85}{100} \ \ \frac{15}{100} )$

and this gives us

(0.85 0.15)

(c) we simply multiply the above two matrices to find the percent of the population can be expected to be in each category after one year after

$\left[\begin{array}{cc}0.85&0.15\end{array}\right] \left[\begin{array}{cc}0.93&0.07&\\0.01&0.99&\end{array}\right] = \left[\begin{array}{cc}0.792&0.208&\end{array}\right]$

in the city there are 79.2% while in the suburb, there are 20.8%

asambeis [7]

Answer:

x=29

Step-by-step explanation:

(x+3)+(x-1)+(x+1)=90

x+3+x-1+x+1=90

3x+3=90

3x=90-3

x=87/3

x=29

x+3=32

x+1=30

x-1=28

Checking

(x+3)+(x-1)+(x+1)=90

(29+3)+(29-1)+(29+1)=90

32+28+30=90

90=90
