Customers at a gas station pay with a credit card (A), debit card (B), or cash (C). Assume that successive customers make indepe
Maurinko [17]

Answer:

Mean = 20

Variance = 16

Step-by-step explanation:

Solution:-

- Let X be the number of customers paying with a debit card.  X has the binomial distribution with n = 100 trials and success probability p = 0.2  

- In general, if X has the binomial distribution with (n) trials and a success probability of (p) then:

                 P[X = x] = n!/(x!(n-x)!) * p^x * (1-p)^(n-x)

                 for values of x = 0, 1, 2, ..., n  

                 P[X = x] = 0 for any other value of x.

- The probability mass function is derived by looking at the number of combination of x objects chosen from n objects and then a total of x success and n - x failures.  

- Or, in other words, the binomial is the sum of n independent and identically distributed Bernoulli trials.

                  X ~ Binomial( n = 100 , p = 0.2 )

- The mean of the binomial distribution is n * p = 20  

- The variance of the binomial distribution is n * p * (1 - p) = 16

What is Segregation of alleles?

  • Allele pairs (several features of the same gene) are segregated during meiosis so that they can be transferred selectively to different gametes.
  • During meiosis, maternal and paternal alleles separate.

What is genotype vs phenotype ?

  • Genotype: An organism's genetic makeup.
  • Phenotype. physical characteristic that arises within an organism as a result of its genotype. Probability law.
  • Genotype - the set of alleles that make up an organism.

How does genotype influence phenotype ?

  • The alleles you have for a specific gene or collection of genes are referred to as your genotype.
  • The physical attribute itself, or phenotype, can be affected by both genotype and environmental variables.

Step-by-step explanation:

3x-1=2x2 (calculate the product)

3x-1=4x (move terms)

3 x - 4 x =1 (collect the terms)

- x = 1 (change the signs)

Solution is x = -1
