Answer:
36 cm^2.
Step-by-step explanation:
The area is half the product of the lengths of its diagonals.
(PA)(LY) = (12cm)(6cm)
= 72 cm
72cm ÷2= 36 cm^2
Therefore the area is 36 cm^2
Number 1 = 17
number 2 = 72
number 3 = 24
work:
the three numbers are symbolized as x, y, and z
x + y + z = 113
number 2 (y) is 3 times the third number (z) so
y = 3z
so x + 3z + z = 113
the first number (x) is 7 less than than the third number (z) so
x = z - 7
so z -7 + 3z + z = 113
5z - 7 = 113
5z = 120
z = 24
x = 17
y = 72
Hope this helped :)
If you apply a linear transformation
to a random variable X, the mean and standard deviations change as follows:
So, the new mean is
and the new standard deviation is
Answer:
x = 6
y = 4
Step-by-step explanation:
Apply the angle bisector theorem to solve for x and y respectively.
✔️4/(9 - x) = 8/x
Cross multiply
4*x = 8(9 - x)
4x = 72 - 8x
Add 8x to both sides
4x + 8x = 72
12x = 72
12x/12 = 72/12
x = 6
✔️y/2 = 6/3
Cross multiply
3*y = 6*2
3y = 12
3y/3 = 12/3
y = 4
