Perimeter of square is 48 inches.
Square has 4 side so one side is 48/4= 12 inches.
Then the area of square is 12*12 = 144 inches^2
Answer:
3/2 or 1.5
Step-by-step explanation:To find the perimeter you need to multiply the four sides why the same number like: 3/8in(4)wich equal 3/2in or in decimal point 1.5 hope it helps. :)
Answer:
Step-by-step explanation:
Given
--- Average
--- Average
Required
Determine the overall average
Represent the sum of the first three with x.
So:
Solve for x
Represent the sum of the next seven with y.
So:
Solve for y
The overall average is calculated as thus:
Answer:
4826809 and 6
Step-by-step explanation:
(a)
Given
{ 5² + 12² }³ ← evaluate contents of bracket
= (25 + 144)³
= 169³
= 4826809
(b)
Evaluate contents of parenthesis
= (1 + 8 + 27) = 36, that is
= = 6
Answer:
And we can find this probability using excel or the normal standard tabe and we got:
Step-by-step explanation:
Previous concepts
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".
Solution to the problem
Let X the random variable that represent the temperatures of a population, and for this case we know the distribution for X is given by:
Where and
We are interested on this probability
And the best way to solve this problem is using the normal standard distribution and the z score given by:
If we apply this formula to our probability we got this:
And we can find this probability using excel or the normal standard tabe and we got:
