Answer:
s+6+s+6+s+s+2s=102, s=18
Step-by-step explanation:
The perimeter is the sum of the side lengths, so
the equation is s+6+s+6+s+s+2s=102.
Answer:
odd degree and positive leading coefficient
Step-by-step explanation:
From the graph , we can see that when x goes to infinity , y goes to infinity
As x--> ∞, y--> ∞ (As x increases the value of y increases on the positive side)
we can see that when x goes to -infinity , y goes to -infinity
As x--> -∞, y--> -∞ (As x decreases the value of y decreases on the negative side)
When x--> ∞, y--> ∞ and x--> -∞, y--> -∞
The leading coefficient is positive and largest exponent is odd
So the graph has odd degree and positive leading coefficient
<u>Given</u>:
Let the random variable x is normally distributed with mean 
and 
We need to determine the probability of 
<u>Probability of </u><u>:</u>
The formula to determine the value of is given by
Thus, we have;
Simplifying, we get;
Using the normal distribution table, the value of -2 is given by 0.0228
Thus, the value of is 0.0228

Answer:
y = -2.8x +69.4
Step-by-step explanation:
The 2-point form of the equation of a line can be used to find the equation of the line through points (3, 61) and (13, 33). The general form of it is ...
y = (y2-y1)/(x2-x1)·(x -x1) +y1
For the given points, this is ...
y = (33 -61)/(13 -3)·(x -3) +61
y = -28/10(x -3) +61
y = -2.8x +69.4 . . . . . the equation of the line through the given points

<em>Comment on the problem</em>
A "line of best fit" is one that minimizes some measure of deviation from the line. Usually, what is minimized is the square of the deviations. Choosing two points to draw the line through may be convenient, but does not necessarily result in a line of best fit.
