Answer:

x=12

Step-by-step explanation:

3x/6 + 2 = 8

Subtract 2 from each side

3x/6 + 2-2 = 8-2

3x/6 =6

Multiply each side by 6/3

6/3 * 3/6 x = 6 *6/3

x = 36/3

x = 12

Take x-2 and insert it into 2x^2 + 3x-2 where the x is located 
2x^2 + 3x-2
2(x-2)^2 + 3(x-2)-2

Now work out 2(x-2)^2 + 3(x-2)-2 also follow PEMDAS
2(x-2)^2 + 3(x-2)-2 
Since (x-2)^2 is an Exponent, lets work with that first and expand (x-2)^2.
(x-2)^2
(x -2)(x-2)
x^2 -4x + 4
Now Multiply that by 2 because we have that in 2(x-2)^2
(x-2)^2  =  x^2 -4x + 4
2(x-2)^2  =  2(x^2 -4x + 4)
2(x^2 -4x + 4) = 2x^2 - 8x + 8
2x^2 - 8x + 8

Now that 2(x-2)^2 is done lets move on to 3(x-2).

Use the distributive property and distribute the 3
3(x-2) = 3x - 6

All that is left is the -2 

Now lets put it all together 
2(x-2)^2 + 3(x-2)-2

2x^2 - 8x + 8 + 3x - 6 - 2

Now combine all our like terms 
2x^2 - 8x + 8 + 3x - 6 - 2
Combine:  2x^2      =  2x^2 
Combine: -8x + 3x  =  -5x
Combine:  8 - 6 - 2 =   0

So all we have left is
2x^2 - 5x

The heights of the trees in a forest are normally distributed, with a mean of 25 meters and a standard deviation of 6 meters. Wh
Alla [95]

Answer:

2.3%

Step-by-step explanation:

The formula to convert x into z distribution is

z=\frac{x-\mu}{\sigma}

Where z is the test statistic

x is what we are looking for (in this case 37)

\mu is the mean (in this case, it is 25)

\sigma is the standard deviation (we have 6)

<em>Plugging these into the formula, we get:</em>

z=\frac{x-\mu}{\sigma}\\z=\frac{37-25}{6}\\z=2

Thus we can say we want P(z\geq 2)

<u>Note: </u> P(z\geq a)=1-P(z\leq a)

The table given is for any  z where P(z\leq a)

Thus, now we have:

P(z\geq 2)\\=1-P(z\leq 2)\\=1-0.9772\\=0.0228\\

0.0228 into percentage is 0.0228 * 100 = 2.28%

Rounded, we get 2.3%

Third answer choice is right.

A pair of basketball shoes was originally priced at $80, but was marked up 47.5%. What was the retail
Lelu [443]
47.5% in decimal form is 0.475.

Since the price was increased, we add 1 to 0.475 to get 1.475.

80 * 1.475 = 118

Another way to solve this is to multiply 80 by 0.475, which is 38, then add it to 80.

The retail price of the shoes is $118.
