Answer:

8x^2+19x

Step-by-step explanation:

Simplify the expression by combining like terms. Terms which look a like and sound a like should be added together.

3x^2+7x+3+5x^2+12x

x^2 terms: 3x^2+5x^2=8x^2

x terms: 7x+12x=19x

constants: 3

Together is is 8x^2+19x+3.

kicyunya [14]

If you see that 3x-3 and set it equal to x+7 then you will get this,

3x-3=x+7


Now solve for X. You will get 5.

Then you plug five in and get 12 For both sides and then multiply 12 by 4 and get 48.

You answer is 48.

A plant manufactures part whose lengths are normally distributed with a mean of 16.3 centimeters and a standard deviation of 2.5
EastWind [94]

The probability that the plant manufactures a part between 10.8 and 12.8 centimeters 13%

<h3>How to find the probability that the part is between 10.8 and 12.8 centimeters</h3>

The probability is solved z scores, this measures the amount of standard deviation sample X is from mean. the formula is below

z = (X - μ) / σ

<u>Definition of variables</u>

mean, μ = 16.3 centimeters

standard deviation, σ = 2.5 centimeters

X = 10.8 and 12.8 centimeters

z score, z

substituting into the formula

for X = 12.8 centimeters

=  (X - μ) / σ

= (12.8 - 16.3) / 2.5

= -1.4

the p value for z of -1.4 = 0.161513

for X = 10.8 centimeters

=  (X - μ) / σ

= (10.8 - 16.3) / 2.5

= -2.2

the p value for z of -2.2 = 0.027807

the probability is calculated as below

0.161513 - 0.027807= 0.133706

= 0.13

=13%

What is the slope of the line?
White raven [17]

Answer:

-\frac{2}{3} x

Step-by-step explanation:

Hey there!

To find slope, you take \frac{y_{2}-y_{1}}{x_{2}-x_{1}}

In this case

y2: 6

y1: 4

x2: -3

x1: 0

Now we plug in this information

\frac{6-4}{-3-0} \\\\\frac{2}{-3} \\\\-\frac{2}{3}

Since this is the slope, you have to add a "x"

So, the slope is -\frac{2}{3} x
