Of the volunteers donating blood in a clinic, 30% have the Rhesus (Rh) factor present in their blood. (a) If five volunteers are randomly selected, what is the probability that at least one does not have the Rh factor

Answers

Answer 1

Answer:

0.83193

Step-by-step explanation:

Probability of having the Rhesus (Rh) factor present in their blood; p = 0.3

Sample size; n = 5

We want to find the probability the probability that at least one does not have the Rh factor.

This will be;1 - P(X < 1)

This is a binomial probability distribution. Thus;

P(X = k) = C(n, k) × p^(k) × (1 - p)^(n - k)

P(X < 1) = P(X = 0)

Thus;

P(X = 0) = C(5, 0) × 0.3^(0) × (1 - 0.3)^(5 - 0)

P(X = 0) = 1 × 1 × 0.16807

P(X = 0) = 0.16807

Thus;

1 - P(X < 1) = 1 - 0.16807 = 0.83193

The solution of the given system of linear equations using substitution method is [tex]x = -1, y = 18[/tex].

What is substitution method?

The substitution method can be defined as a way to solve a linear system algebraically. The substitution method works by substituting one y-value with the other. To solve it easily, the method involves finding the value of the x-variable in terms of the y-variable. After that, we then end up substituting the value of x-variable in the second equation. This helps us to directly find the value of the y-variable. We can now put the value of y in any of the given equations to find x.

The given system of equations are:

[tex]y + 8x = 10[/tex]..... (1)

[tex]2y - 4x = 40[/tex]..... (2)

The given value of [tex]x = - 1[/tex]. Therefore, the given value of 'x' satisfies for both the equations given.

Now using substitution method, substituting the value of 'x' in the equation(1), we will get the value of 'y'.

Therefore:

[tex]y + 8(-1) = 10[/tex]

⇒ [tex]y = 10 + 8[/tex]

⇒ [tex]y = 18[/tex]

Again, we can verify the value of 'y' by substituting the value of 'x' in equation (2).

Therefore,

[tex]2y - 4(-1) = 40[/tex]

⇒ [tex]2y = 40 - 4[/tex]

⇒ [tex]y = \frac{36}{2}[/tex]

⇒ [tex]y = 18[/tex]

Hence,

The solution of the given system of linear equations using substitution method is [tex]x = -1, y = 18[/tex].

Find the smallest perimeter and the dimensions for a rectangle with an area of 36 in squared.

Answers

Answer:

Therefore the smallest parameters is  (6,6) and a dimension of 24 inches

Step-by-step explanation:

From the question we are told that

area of dimension is  [tex]A=36[/tex]

Generally the perimeter of  rectangle is given as

      [tex]x,y=36[/tex]

Given by

      [tex](x,y)=2x+2y[/tex]

Mathematical solving for perimeter of rectangle

    [tex]x=\frac{36}{y}[/tex]

    [tex]f(y)= 2\frac{36}{2} +2y\\f(y)= \frac{72}{y} +2y[/tex]

Generally in finding minimum perimeter

     [tex]f'(y)=\frac{-72}{y^2} +2=0\\[/tex]

     [tex]y=6[/tex]

[tex]f(6,6)=2(6)+2(6) \\f(6,6)=24 inches[/tex]

Therefore the smallest parameters is  (6,6) and a dimension of 24 inches
