Move all terms containing C to the left side of the equation. -8c-11=21

Move all terms not containing C to the right side of the equation. -8c=32

Divide each term by -8 and simplify.

32/8 equals -4

C=-4

<span> -4c - 11 = 4c +21 add 4c to both sides
</span>
<span> -4c - 11 + 4c = 4c + 21 + 4c simplify

- 11 = 8c + 21</span> <span> subtract 21 from both sides

- 11 - 21 = 8c + 21 - 21 </span><span>simplify

- 32 = 8c divide both sides by 8

c = - 4

That's it

I hope you got the idea

Simplify 4x(2x3-7x2+x)

Gelneren [198K]

To simplify this all you need to do is distribute the 4x across each term in the parenthesis
$4x(2x^3 - 7x^2 + x) \\ (4x)(2x^3) - (4x)(7x^2) + (4x)(x) \\ 8x^4 - 28x^3 + 4x^2$

Daily low temperatures in Columbus, OH in January 2014 were approximately normally distributed with a mean of 15.45 and a standa

Alona [7]

Answer: 12.10

Step-by-step explanation:

Given : Mean : $\mu = 15.45$

Standard deviation : $\sigma = 13.70$

The formula to calculate the z-score :-

$z=\dfrac{x-\mu}{\sigma}$

For x= 5 degrees

$z=\dfrac{5-15.45}{13.70}=-0.7627737226\approx-0.76$

For x= 10 degrees

$z=\dfrac{10-15.45}{13.70}=-0.397810218\approx-0.40$

The P-value : $P(-0.76$

$=0.3445783-0.2236273=0.120951\approx0.1210$

In percent , $0.1210\times100=12.10\%$

Hence, the percentage of days had a low temperature between 5 degrees and 10 degrees = 12.10%
