The proportion of American births that result in a birth defect is approximately 1/33 according to the Centers for Disease Contr
max2010maxim [7]

Answer:

The appropriate probability model for X is a Binomial distribution,

X \sim Bin (<em>n</em> = 5, <em>p</em> = 1/33).

Step-by-step explanation:

The random variable <em>X</em> can be defined as the number of American births resulting in a defect.

The proportion of American births that result in a birth defect is approximately <em>p</em> = 1/33.

A random sample of <em>n</em> = 5 American births are selected.

It is assumed that the births are independent, i.e. a birth can be defective or not is independent of the other births.

In this experiment the success is defined as a defective birth.

The random variable <em>X</em> satisfies all criteria of a Binomial distribution.

The criteria are:

  • Number of observations is constant
  • Independent trials
  • Each trial has only two outcomes: Success and Failure
  • Same probability of success for each trial

Thus, the appropriate probability model for X is a Binomial distribution, Bin (<em>n</em> = 5, <em>p</em> = 1/33).

C. Make n subject of the formula<br>S= n/2 [2a + (n - 1)d]<br><br>please provide your working out ​
yKpoI14uk [10]

Answer:

n=\frac{4as -2ds}{(1-2ds)}

Step-by-step explanation:

S= \frac{n}{2 [2a + (n - 1)d]}

Simplifying the fraction by multiplying d into the (n-1) term,

s=\frac{n}{2 [2a + (n - 1)d] } = \frac{n}{2[2a + dn - d] }

Simplifying the fraction by multiplying 2 throughout,

s= \frac{n}{4a + 2dn-2d}

Multiply (4a + 2dn-2d) on both sides

(4a + 2dn-2d)s= \frac{n}{4a + 2dn-2d} (4a + 2dn-2d)

Cancel the (4a + 2dn-2d) on the right hand side

(4a + 2dn-2d)s= n

Multiply s to the terms,

4as + 2dns-2ds= n

Move 2dns to the right hand side by subtracting 2dns on both sides4as + 2dns-2ds-2dns= n-2dns

4as -2ds= n-2dns

On the right hand side of the equation, take out n

4as -2ds= n(1-2ds)

Divide Left hand side by (1-2ds),

n=\frac{4as -2ds}{(1-2ds)}
