<h3>
Answer: 1/12</h3>
=========================================================
Explanation:
There are 3 red out of 9 total
The probability of picking red at random is 3/9 = 1/3
If the first marble is not put back, then the chances of picking red again are now 2/8 = 1/4
Notice how I subtracted 1 from the numerator and denominator of 3/9 to get to 2/8. This is because the red count and the total count both go down by 1 each.
Now multiply the fractions mentioned:
(3/9)*(2/8) = (1/3)*(1/4) = (1*1)/(3*4) = 1/12
If you did this trial 12 times, then you should expect to get two reds about once. That's one way to interpret the probability of 1/12.
Side note: 1/12 = 0.0833 = 8.33% approximately
16/2=8
we need 8 times more flowers
8x8,000=64,000
64 thousand flowers
Hope that helps)
Plug in the f(x+1)
f(x+1) = (x+1)^2
I would say number 1. looks the most correct

Answer:
A
Step-by-step explanation:
The area of a square is A = s². So the area of this square is A = (2x+2)² = 4x² + 8x + 4.
The perimeter of the triangle is 4/3x + 4/3x+4/3x = 12/3x = 4x.
The difference between the two values is subtraction. Subtract the expressions and simplify.
4x² + 8x + 4 -4x = 4x² + 4x + 4
This expression is also equal to 3. Set it equal to 3 and solve for x.
4x² + 4x + 4 = 3
4x² + 4x + 1 = 0
Substitute a = 4, b = 4 and c = 1 into the quadratic formula.
The quadratic formula is
.
Substitute and you'll have:
Answer:
side: 4 metres
perimeter: 16 metres
Step-by-step explanation:
Let's first find the area of this rectangle.
The area of a rectangle is denoted by A = lw, where l is the length and w is the width. Here, the length is l = 6.4 and the width is w = 2.5. Plug these in:
A = lw
A = 6.4 * 2.5 = 16 metres squared
We want to find the side of a square with area 16. Suppose the side length is x. The area of a square is denoted by A = x * x = x², so set this equal to 16:
x² = 16
x = √16 = 4
Thus, the side length is 4 metres.
The perimeter of a square is denoted by P = 4s, where s is the side length.
Here the side length is 4 metres, as we found, so:
P = 4s = 4 * 4 = 16
Hence the perimeter is 16 metres.
