Answer:
1
4h﹣a4+2(ab)2+2(ac)2﹣b4+2(bc)2﹣c4
Step-by-step explanation:
I don’t really know how to explain it’s sry.
The event space of getting exactly one tail is {HT, TH}
The sample space is {HH, HT, TH, TT}
There are two ways to get exactly one tail, out of 4 total possible outcomes.
So 2/4 = 1/2 is the answer
Answer: Option 'a' is correct.
Step-by-step explanation:
Since we have given that
Probability of owned a sedan = 39%
Probability of owned a van = 33%
Probability of owned a sports car = 7%
n = 3
We need to find the probability that all three randomly selected households own a van.
So, Probability of getting all 3 own a van is given by
Hence, Option 'a' is correct.
F is proportional to 1/x^2
distance = x
A reduction of 25 percent = 0.75x
Let’s put this in place of x
F = 1/(0.75x)^2
And simplify
F = 1/0.5625x^2
So you need to find the percentage increase from 1/x^2 to 1/0.5625x^2
So what does 1/x^2 multiply by to give 1/0.5625x^2
Written as an equation it is y/x^2 = 1/0.5625x^2
Multiply both sides by x^2
y = 1/0.5625
y = 1.778 (rounded to 3 decimal points)
So the decimal multiplier is 1.778 and so the percent increase is approximately 77.8%
