The probability of being a universal donor is 6% (O-negative-blood type). Suppose that 6 people come to a blood drive.' a) What

Tcecarenko [31]

Answer:

$Mean = 0.36$

$SD = 0.5817$

$P(x=3) = 0.003588$

Step-by-step explanation:

Given

Let

A = Event of being a universal donor.

So:

$P(A) = 0.06$

$n = 6$

Solving (a): Mean and Standard deviation.

The mean is:

$Mean = np$

$Mean = 6 * 0.06$

$Mean = 0.36$

The standard deviation is:

$SD = \sqrt{np(1-p)}$

$SD = \sqrt{6*0.06*(1-0.06)}$

$SD = \sqrt{0.3384}$

$SD = 0.5817$

Solving (b): P(x = 3)

The event is a binomial event an dthe probability is calculated as:

$P(x) = ^nC_x * p^x * (1-p)^{n-x}$

So, we have:

$P(x=3) = ^6C_3 * 0.06^3 * (1-0.06)^{6-3}$

$P(x=3) = ^6C_3 * 0.06^3 * (1-0.06)^3$

$P(x=3) = 20 * 0.06^3 * (1-0.06)^3$

$P(x=3) = 0.003588$

Make b the subject of this equation A = 1/2 x b x h

aalyn [17]

The equation is $b=\frac{2A}{h}$

Step-by-step explanation:

Let us revise how to make a variable subject of an equation

Write the equation and circle the variable you want to make it subject
Keep it in one side and move all other in the other side
Make the coefficient of the subject 1

∵ A = $\frac{1}{2}$ × b × h

∵ b is the subject

∴ Multiply the two sides by 2

∴ 2A = b × h

- Divide both sides by h

∴ $\frac{2A}{h}= b$

- Switch the two sides

∴ $b=\frac{2A}{h}$

The equation is $b=\frac{2A}{h}$

a blue arlin can swim at 50miles per hour. What is that speed in feet per second , to the nearest whole number ?

morpeh [17]

Step-by-step explanation:

Multiply the amount of feet in one mile by the amount of miles in the question(5,280 x 50 = 264,000)

Divide the amount of feet in 50 miles by the amount of minutes in 1 hour to get the amount of feet per mile (264,000 ÷ 60 = 4,400)

Divide the amount of feet per mile to get by the amount of seconds in a minute to get the amount of feet per second (4,400 ÷ 60 = 73.33)

Your answer rounded to the nearest whole number is 73
