Step-by-step explanation:
Replacement means the probability of each trial is the same (the trials are independent).
For example, let's say you have a standard deck of 52 cards, and you want to find the probability of drawing a queen card twice.
There are 4 queens, so the probability on the first draw is 4/52.
You then replace the queen, so there are still 4 queens in the deck. So the probability on the second draw is still 4/52.
The total probability is the product: 4/52 × 4/52 = 1/169
If you didn't replace the queen after the first draw, there would have been 3 queens in the deck, and the probability on the second draw would have been 3/52.

Correct question :
If the perimeters of each shape are equal, which equation can be used to find the value of x? A triangle with base x + 2, height x, and side length x + 4. A rectangle with length of x + 3 and width of one-half x. (x + 4) + x + (x + 2) = one-half x + (x + 3) (x + 2) + x + (x + 4) = 2 (one-half x) + 2 (x + 3) 2 (x) + 2 (x + 2) = 2 (one-half x) + 2 (x + 3) x + (x + 2) + (x + 4) = 2 (x + 3 and one-half)
Answer: (x + 2) + x + (x + 4) = 2 (one-half x) + 2 (x + 3)
Step-by-step explanation:
Given the following :
A triangle with base x + 2, height x, and side length x + 4 - - - -
b = x + 2 ; a = x ; c = x + 4
Perimeter (P) of a triangle :
P = a + b + c
P =( x + 2) + x + (x + 4) - - - (1)
A rectangle with length of x + 3 and width of one-half x
l = x + 3 ; w = 1/2 x
Perimeter of a rectangle (P) = 2(l+w)
P = 2(x+3) + 2(1/2x)
If perimeter of each same are the same ; then;
(1) = (2)
(x + 2) + x + (x + 4) = 2(x+3) + 2(1/2x)

Answer:
2112
Step-by-step explanation:
we find the area of the base first
which is 16*12/2 because it is a right triangle
16*12/2 = 96
then we multiply the base by the height
22*96 = 2112
as a note, remember, prism volume is all base * height
