The mean = sum of all the measurements / number of measurements (n)
= (5 + 3 + 3 + 8 + 8) / 5
= 27 / 5
= 5.4 Answer
Answer:
Step-by-step explanation:
We know sum of the interior angles of a quadrilateral is 
therefore we can write

so



So smallest interior angle is 
Largest interior angle 
Answer: PSR (Perfect Square Rule) = (x-3/2)^2
The you simplify.... = x^2 - 3x + 9/4
Step-by-step explanation: Factor by using the PSR (Perfect Square Rule). Then you have to simplify.
Hope this helps you out! ☺
We can start by rewriting the initial equation <span>x +10y=260 in order to express how y depends on x.

This is a linear function ( it's a straight line). Linear functions have two intercepts, y and x.
To find x-intercept (also called zero of a function) we set y=0 and we solve for x.



This means that at x=260 our function has a value of 0. y(x) represents a distance from the school. This means that when y(x) is 0 our athlete reached school (finished the race), so this also answers your second question. The time it takes an athlete to finish the race is 260 minutes.
The y-intercept a value of our function at x=0. This gives us a distance of our athlete from the school at the start of the race. We find this by plugin x=0 in our equation. We get that y=26 when x=0. This makes perfect sense. Our athlete is 26 miles away from high school at the start of the race.

Answer:
1.2 cm
Step-by-step explanation:
1.8 * 5 = 9
9 - (1.4 + 1.9 + 2.1 + 2.4) = 1.2
1.2 + 1.4 + 1.9 + 2.1 + 2.4 = 9
9/5 = 1.8
