What is this problem in standard form? y-5=3/2(x+6)
1 answer:
Answer:
Step-by-step explanation:
y - 5 = 3⁄2(x + 6)
y - 5 = 3⁄2x + 9
+ 5 + 5
__________
y = 3⁄2x + 14
- 3⁄2x - 3⁄2x
________
−3⁄2x + y = 14 [We do not want mixed numbers\fractions in our standard equation, so multiply by the denominator to get rid of it.]
−2[−3⁄2x + y = 14]

We have to determine
Which expression represents the probability of getting exactly 3 heads?
<h3>What is binomial distribution?</h3>The binomial distribution is determined as the probability of mass or discrete random variable which yields exactly some values.
The binomial probability formula shown has variables which represent:
Where n is the total number of trials (here, we flip penny 9 times, hence n = 9).
r is the number we want to find (here, we want the probability of 3 heads, so r = 3).
p is the probability of success (here, success means getting heads.
So, in a coin flip the probability of heads is always 1/2, so p = 1/2).
Therefore,
The expression represents the probability of getting exactly 3 heads is;
Hence, the expression represents the probability of getting exactly 3 heads is .

To solve this problem, we need to know the formula of the surface area of a triangular prism. The formula is: A = 2
+ (a+b+c) * h
Now we can substitute values and solve
A = 2(0.5 * 4 * 3) + (3+4+5) * 20
A = 12 + 240
A = 252
That means that the answer to this question is 252 square feet.
