Answer:
option d is the correct answer
Answer:
<h2>
x= 2/3</h2>
Step-by-step explanation:
x−6 = 4(2−3x)−8x
Rearrange terms
x-6= 4(-3x+2)-8x
Distribute
x-6= -12x+8-8x
Combine Like Terms
x-6= -20x+8
21x-6= 8
Isolate x
21x= 8+6
21x=14
x= 14/21
Simplify
x=2/3
Answer:
0.00390625
Step-by-step explanation:
For coins :
Number of rolls, trials, n = 4
P(heads) = 0.5
Using binomial probability formula :
P(x =x) : nCr * p^x q ;
P(obtaining exactly 4 heads) = 4C4 * 0.5^4 * 0.5^0 = 1 * 0. 0625 * 1 = 0.0625
P(even number from 4 coin tosses)
Even faces = (2,4,6)
Total faces = (1,2,3,4,5,6)
P(success) = 3/6 = 0.5
P(obtaining exactly 4 even) = 4C4 * 0.5^4 * 0.5^0 = 1 * 0. 0625 * 1 = 0.0625
Hence, obtaining 4 even outcomes and 4 heads = 0.0625 * 0.0625 =0.00390625
The answer is A you times base times height divided by 2
