Answer:
And we can find this probability with this difference
And we can see the figure in the plot attached.
Step-by-step explanation:
Let X the random variable that represent the redings on thermometers of a population, and for this case we know the distribution for X is given by:
Where 
and 
We are interested on this probability
We can use the z score formula given by:
Using this formula we got:
And we can find this probability with this difference
And we can see the figure in the plot attached.
The slope is already given in the question, so we only ned to solve for the y-intercept using y = mx + b.
4 = 3(1) + b
4 = 3 + b
4 - 3 = 3 + b - 3
1 = b
Now, write the equation in slope-intercept form.
y = 3x + 1

Answer:
A = L x W
Step-by-step explanation:
<em>Because the equation of a rectangle is understood the best way to help you understand the equation of l*w is to break down the definiton of a rectangle.</em>
Defining a rectangle:
The rectangle is a quadrillateral with two parallel sets of sides which are perpendicular to each other.
Understanding it:
Now let's look at a rectangle
Let's say the length is 5 units and the width is 10 units.
To find that meat in between we understand that 5 units of length extends through all 10 units of the width. This means 5 is carried out for 10 units meaning that 5x10 is the area of the Rectangle. As such the area would be 50
So the area of a rectangle is its length times its width
Value of expression 
is 
.
<u>Step-by-step explanation:</u>
Here we need to evaluate expression : (3xy/3x^2-12)*(x^2+3x+2/xy+y) or ,
Let's simplify this
⇒ 
Factorizing the terms we get:
⇒ 
{ 
}
⇒ 
⇒ 
Cancelling similar terms we get:
⇒
Therefore , Value of expression is .
