Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
In which is the number of different combinatios of x objects from a set of n elements, given by the following formula.
And is the probability of X happening.
(a) A fair die is rolled 50 times. X = number of times a 5 is rolled
The die is rolled 50 times, so .
Each roll can have 6 outcomes. So the probability that 5 is rolled is
(b) A company puts a game card in each box of cereal and 1/100 of them are winners. You buy sixteen boxes of cereal, and X = number of times you win.
You buy 16 boxes of cereal, so .
1 of 100 are winners. So .
(c) Jack likes to play computer solitaire and wins about 25% of the time. X = number of games he wins out of his next 26 games.
He plays 26 games, so .
He wins 25% of the time, so
We have that . So
Answer:
y = x + 8
Step-by-step explanation:
The equation of a line in slope- intercept gorm is
y = mx + c
Given
3x - 2y = - 16 ( subtract 3x from both sides )
- 2y = - 3x - 16 ( divide all terms by - 2 )
y = x + 8 ← in slope- intercept form
Answer:
Solution given:
letA=(10,-4)
B=(-2,-4)
centre[C](h,k)=
radius=units
we have
Equation of a circle is;
(x-h)²+(y-k)²=r²
(x-4)²+(y+4)²=36
or.
x²-8x+16+y²+8y+16=36
x²-8x+8y+y²=36-32
x²-8x+8y+y²=4
