Answer:
a) We conclude that the menager use the hypergeometric distribution.
b) We conclude that the menager use the binomial distribution.
Step-by-step explanation:
a) We know that in probability theory, the hypergeometric distribution is a discrete probability distribution that describes the probability of k successes in n draws, without replacement.
We conclude that the menager use the hypergeometric distribution.
b) We know that the binomial distribution describes the probability of k successes in n draws with replacement.
We conclude that the menager use the binomial distribution.
The product (-3xy³/2x⁴y)*(4x/-7x²y) = (3xy³/2x⁴y)*(4x/7x²y)=
=(6y)/(7x⁴)
where y≠0
x should not be equal 0 also
Answer:
Step-by-step explanation:
Given
← factorise numerator and denominator
2x² - 18 ( factor out 2 from each term )
= 2(x² - 9) ← difference of 2 squares
= 2(x - 3)(x + 3)
and
x² + 4x - 21 = (x + 7)(x - 3) , then
= 
← cancel common factor (x - 3) on numerator/ denominator
=
Answer:
$108
Step-by-step explanation:
3X9= 27square foot. Then you multiply 27 by 4, which equals $108
The slope is -1/2
Step by step
1) formula m=y2-y1/x2-x1
2) slope equals = -1+2/-8+6
3) 1/-2
4) answer is -1/2
