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.

Find a. Write your answer in simplest radical form.
NeTakaya

Answer:

\sin(60)  =  \frac{5 \sqrt{3} }{a}  \\  \\  \frac{ \sqrt{3} }{2}  =  \frac{5 \sqrt{3} }{a}  \\  \\ a =  \frac{2 \times 5 \sqrt{3} }{ \sqrt{3} }  \\  \\ a = 10

3. Use the following table to answer questions (a – c).
sineoko [7]

Answer:

See below

Step-by-step explanation:

B) The correlation coefficient is r=0.75, which can be determined by plugging the data into a TI-84 calculator.

C) A correlation coefficient of r=0.75 indicates that the correlation between the independent and dependent variable (x and y in this case) is moderately strong with a positive correlation. The closer r is to 1, the stronger the positive correlation. The closer r is to -1, the stronger the negative correlation. If r is closer to 0, then there's no correlation.

PLEASE HELP ASAP!!!!!!!!!!!!!!!!!
Kamila [148]

Answer:

Twelve tickets cost $30 --> True

Thirty tickets cost $12 --> False

Each additional costs $2.50 --> True

The table is a partial rep --> True

ordered pairs --> False

Step-by-step explanation:

Twelve tickets cost $30 --> True, you can literally see that in the table

Thirty tickets cost $12 --> False, 30 is not in the table so you don't have that information. Besides, $12 is an unlikely low value for so many tickets.

Each additional costs $2.50 --> True, you can see the difference in the TotalCost column to be consistently 2.50.

The table is a partial rep --> True, values below 11 are not shown for example.

ordered pairs --> False --> Then the x value should be first, e.g., (11, 27.50), since the cost y is a function of the number x.
