Answer:
add all the numbers and divide then by how many numbers there are in the data.
Step-by-step explanation:
5+7+7+5+1+0+6+8+5+9+8=61
how many numbers are in the data? 11
divide 11 and 61.
61/11=5.54
mean=5.54 (54 repeats. 5.5454545454545 etc.)
7.79cm It is an equilateral triangle so it has 3 equal sides. That means each side is 9cm. <span>
Now draw a line from the top of the equilateral triangle to the base, and dividing it into two. You will have made two smaller triangles, with sides 9, 4.5, and h (the one you want to find).
A line drawn from the apex of an equilateral triangle to the midpoint of the base is perpendicular to the base, so you can use Pythagoras' Theorem!
4.5^2 + h^2 = 9^2
h = sqrt(9^2 - 4.5^2)
Therefore, the height is 7.79cm (2 decimal places)</span><span>

Answer:
in question one you will pick option 1
in second the 3rd option
in last question option 4
The answer for the question shown above is the first option: x^2(x^2)^1/4
When you simplify the expression, you obtain the equivalent expression:
(x^10)^1/4
[(x^8)(x2)]^1/4
x^2(x^2)^1/4
Therefore, the asnwer is the option mentioned before.
