2+3(x-3)+1-5(2-x)

The first thing we must do is distribute...

2 + 3x - 9 + 1 - 10 + 5x

Then we must combine like terms. We can combine terms with an x together and we can combine terms without an x together.

2 - 9 + 1 - 10 = -16
3x + 5x = 8x

So our simplified expression is C. 8x - 16

Which expression is equivalent to 2^6 x (2^2)^3? O A 212 B. 215 O c. 236 OD 254

Semenov [28]

A. $\bold{\boxed{\green{2^{12}}}}$

Answer:

Solution given:

$2^6 x (2^2)^3$

we know that

product of power and power is added and power to power is multiplied for same base only.

I.E.

product of same base but different power: $a^b+a^c=a^(b+c)$

power to power : $(a^b)^c=a^(b*c)$

By using above property

$2^6+2^{2*3}$

$2^6+2^6$

$2^{[6+6]}=2^{12}$

The population of lengths of aluminum-coated steel sheets is normally distributed with a mean of 30.0 inches and a standard devi

alexira [117]

Answer: 0.8490

Step-by-step explanation:

Given : The population of lengths of aluminum-coated steel sheets is normally distributed with a mean of 30.0 inches and a standard deviation of 0.9 inches.

i.e. $\mu=30$ and $\sigma=0.9$

Let x denotes the lengths of aluminum-coated steel sheets.

Required Formula : $z=\dfrac{x-\mu}{\dfrac{\sigma}{\sqrt{n}}}$

For n= 36 , the probability that the average length of a sheet is between 29.82 and 30.27 inches long will be :-

$P(29.82$

∴ Required probability = 0.8490
