A certain manufactured item is visually inspected by two different inspectors. When a defective item comes through the line, the
andreev551 [17]

The fraction of a defective item getting by both inspectors is \frac{5}{100} = \frac{1}{20}

Step-by-step explanation:

Step 1; Assume that the probability of the first inspector missing a defective part is P(A) and the probability of the second inspector missing those that do get past the first inspector is P(B).

Step 2; It is given that P(A) = 0.1, we convert this into a fraction so that the final probability will be a fraction and not a decimal.

P(A) = 0.1 = \frac{1}{10}.

It is given that the second inspector misses 5 out of 10 that get past the first inspector, so P(B) = \frac{5}{10}.

Step 3; To calculate the probability of both inspectors missing a defective part, we multiply both the probabilities.

P(A and B happening) = P(A) × P(B) = \frac{1}{10} × \frac{5}{10} = \frac{5}{100} = \frac{1}{20} = 0.05%. So there is a 0.05% chance of both inspectors missing a defective part.

How would I graph this and find the solution to this system. <br> y=-1/2x+4
Lesechka [4]

Answer: Easy, graph and solution

Step-by-step explanation: First what you want to do  use the slope intercept form to find the slope and y intercept; -1/2 and y intercept (0,4). Any line can be graphed using 2 points. Select two x values, plug them into the equation to find the corresponding y values. Solution

1.) Step; x and y

Table:

             0║4

             8║0

  • All you had to do is divide 0=-x/2 +4= .  (8) For the x intercept you get 8and for y you get 4 because you divided  0=-0/2+4

Given loga (m) = 10 and loga (n) = 25 , find loga (m * n ^ 2)
mina [271]

The result of the log function log_a (m * n ^ 2)  is 60

According to the law of logarithm if log_ab=y then b=a^y

Given the following expressions

log_am=10\\log_an=25

This can be expressed as

m =a^{10} \ and \ n = a^{25}

Substitute the value of m and n into the expression log_a (m * n ^ 2) to have:

log_a (m * n ^ 2) = log_a(a^{10}\times a^{50})\\=log_aa^{60}\\=60log_aa\\=60(1) \\= 60

This shows that the result of the log function log_a (m * n ^ 2)  is 60
