Step-by-step explanation:
write what you know
square- all sides are equal
area of a square
A = L x W
where A = 81
L = sqrt(81)
W = sqrt(81)
perimeter the length around the square
P = sum of all sides
you can find hypotenuse using pythagorean thm
c=sqrt( L^2 + W^2)
A) if the area of the square is 81, than that will mean that the length of all the sides are 9. You find the Perimeter by adding up all of the sides. So that will mean you do 9+9+9+9 which equals 36.
B) The diagonal that I got for the square is 12.728. The formula to find the diagonal is d=a sqrt 2.
Hope this helps!

A jar contains 2 red, 5 green, 2 blue and 6 yellow marbles. A marble is chosen at random from the jar. After replacing it, a second marble is chosen. What is the probability of choosing a green and then a yellow marble?
Answers
Answer:
Step-by-step explanation:
The probability of picking an item A in a box of N items depends on nA, the amount of items A in the box at the time of picking, with the kinda instinctive value:
p = nA / N
then it means that if you have no green ball, the probability is 0/N = 0, if you only have green balls, it means you have a probability of N/N = 1 = 100%, and if you have as many green balls as non-green balls, you have a probability of nA/(2nA) = 0.5 = 50%.
Here the probability of first picking a green ball (nG=5) in a box of N=3+5+2+6=16 for the 1st pick is:
pG1 = 5/16
Now the trick here is that once you picked the green ball, you put it back in the box before picking another ball. So you still have N=16 balls for the second pick, and the probability of picking a yellow ball (nY=6) for the 2nd pick is:
pY2 = 6/16 = 3/8
(it would have been slightly higher, at 6/15, if you did NOT put back the green marble in the box).
Now you want BOTH events to be true. So you want G1 to be true AND Y2 to be true. The two events are independent (the probability of Y2 is 6/16 if you had G1 but is also 6/16 if you failed G1), so the probability of having both is simply done by multiplicating them:
pG1Y2 = pG1 * pG2 = 15/128

Answers
Answer:
18
Step-by-step explanation:
So what you need to find is the scale factor which is the scale of the difference between two lengths.
So Figure A is smaller than Figure B, as can be easily detected with our eyes.
Figure A has a ratio of 1/2, as 6/12 is equal to 1/2.
Since B is the original, where A is a scaled version, it must also have the same ratio of 1/2, so twice 9 is 18, which is your answer.
You can also use fractions, by making Figure A into 1/2 because 1/2 = 6/12.
Figure B can turn into 9/x.
Since you know they are scaled factors, they have the same ratio since one is scaled larger or smaller than from the original.
Since it must follow the multiplication of 2 for the side length, 9 x 2 gives your answer.

What is the difference between mean and median
Answers
The difference between the mean and median is that the mean is the average number. f.e: 1, 2, 2, 2, 3, 3, 4, 5 - and if you add all those up, the mean would be 3, or 2.
But the median is the number in the middle Number.
What if you have 2 medians, though?
Well, that’s easy to solve IMO.
F.e: 22, 22, 23, 23, 23, 24, 24, 24, 25, 25
The median is either 23 or 24, right?
Okay. That’s simple. But what exactly do we do?
Let me show you:
So get the sum of 23 and 24, which is 47.
Now divide 47 by 2. And what do we get?
23.5.
Now round that, and you get 24. So 24 is the median!
Hope that helps!
Answer:
mean is the AVERAGE of all numbers
Step-by-step explanation:
because when you add up all the numbers then you divide it by the TOTAL NUMBER of NUMBERS!
and a median is the middle number in a sorted, ascending or descending, list of numbers and can be more descriptive of that data set than the average.

buck is building a horse corral with the shape and dimensions shown in the sketch. He wants to make sure the corners of the corral measure 90 degrees
how long must diagonal AC be so angle B is a right angle?
uprgigt corner is D other side is C
Downleft is A across from B
16 ft down and 12 ft side
Answers
Answer:
BxA=F
Step-by-step explanation:
Diagonal AC must be 20 feet so that ∠B will be 90°.
According to asked question, buck is creating a horse coral by designing in such a way that corners will be at 90°.
So according to question we have to make ∠B as 90°.
So quadrilateral ABCD becomes a rectangular.
Therefore ΔABC will be a right-angle triangle in which we can use Pythagoras theorem to measure the diagonal AC.
What is Pythagoras Theorem?The Pythagoras Theorem says that in a right-angle triangle, the square of the hypotenuse is the sum of square of the other two sides of the right-angle triangle.
In the right-angle tringle ΔABC,
AC²=AB²+BC²
⇒ AC²=16²+12²
⇒ AC²=256+144=400
⇒AC=√400
⇒AC=20 feet
Therefore, Diagonal AC must be 20 feet so that ∠B will be 90°.
