Hey there!!
Sooo to answer your question, To find the mean<span> of a </span>data set your going to have to <span>add all the values in the set together and divide by the number of values in the </span>set<span>. Then the total will be your mean also keep in mind that
the mean is another name for average.
Hope this helped and have a great day!!</span>
Answer:
D
Step-by-step explanation:
The quadratic formula:
where a is the coefficient of , b being the coefficient of and c being the constant.
Plug in the values:
Since
The answer is:
So, what you’re doing here is basically finding the measurements of a right triangle, so we’ll use the formula
a^2+b^2=c^2
now, we plug in what we have
12^2+x^2= 19^2
144+x^2= 361
Bring the variable to one side by subtracting 144 from each side
x^2= 217
Square root each side to get rid of the exponent on the x
x= 14.7309
ANSWER:
15 inches
The perimeter of the rectangle is by definition:
P = 2W + 2L
Where,
W: width
L: long
We have then:
P = 2 (5.5 * 6) +2 (5.5 * 8)
P = 154 cm
The area of the rectangle is by definition:
A = (W) * (L)
Where,
W: width
L: long
We have then:
A = (5.5 * 6) * (5.5 * 8)
A = 1452 cm ^ 2
Answer:
Perimeter = 154 cm, area = 1,452 cm2
