There are 6+5 marbles.
Of those, 5 are red.
The chances of drawing a red marble are 5/11
Since you replace the marble you drew, the chances each draw remain 5/11
You cannot draw two red marbles without drawing a red marble on your first draw, so the odds of you making a second draw are 5/11. The odds of that also being red are 5/11… but we only care about that 5/11ths the time
5/11*5/11=25/121
The answer you are looking for would be "T = 5"
To find "T", you'd replace the "X" with the value stated (1). This would give you "T = 3*1 + 2". Solving for "T" can be done by using PEMDAS. First, multiply 3 and 1. This gives you 3, which you then add 2 to. Giving you a final answer of "T = 5".
I hope this helps!
Answer:
388
Step-by-step explanation:
We need to find the area of the semicircle and parallelogram separately and then combine.
The formula for the area of a semicircle is 1/2(pi*r^2)
r = 12. 12^2 = 144
1/2(pi*144) = 226..1946711 which we can just round to 226
The formula for the area of a parallelogram is bh
b = 18, h = 9. 18*9 = 162.
226+162 = 388
Answer:
D
Step-by-step explanation:
The length of the rectangle is 6 inches shorter than the length of s, while the width of the rectangle is 1 inch longer than the length of s
Length of rectangle = s -6
Width of rectangle = s + 1
P rectangle = 2L + 2W or 2(L+W)
=> 2((s-6)+(s+1))
=> 2(2s-5)
=> 4s - 10
Answer:
A. 5(9x-z)
Step-by-step explanation:
45x-5z
We can factor out a 5 from each term
5(9x -z)
