Three machines A, B, and C produce 55%, 25% and 20% respectively. The percentages of defective output are 3.5%, 4.5% and 5.5%. I

pishuonlain [190]

We are given the following information concerning the three production machines;

$\begin{gathered} Of\text{ the total production;} \\ A=55\text{ \%}=0.55 \\ B=25\text{ \%}=0.25 \\ C=20\text{ \%}=0.20 \end{gathered}$

Also, we are given the percentage of defective output as follows;

$\begin{gathered} A=3.5\text{ \%}=0.035 \\ B=4.5\text{ \%}=0.045 \\ C=5.5\text{ \%}=0.055 \end{gathered}$

Therefore, if an item is selected randomly, the probability that the item is defective would be;

$\begin{gathered} P\lbrack defective\rbrack=(0.55\times0.035)+(0.25\times0.045)+(0.20\times0.055) \\ P\lbrack\text{defective\rbrack}=0.01925+0.01125+0.011 \\ P\lbrack\text{defective\rbrack}=0.0415 \end{gathered}$

ANSWER:

The probability that the item is defective would be 0.0415

Six trigonometric functions when an angles coordinates are (12,5)

Nikolay [14]

X = 12 y = 5... to get r you'll add 12^2 + 5^2 = r^2. From there you just place the numbers in trig functions.. sin= y/r cos=x/r tan=y/x csc=r/y and so on. If you draw the triangle it's much easier than it looks here.

You're in high school and can't do this, wow that's sad since i'm in seventh grade. Anyway you divide 2 from $47.00 to get $23.50 and 3 divided by $47.00 to get $15.66 repeated. round to get $15.67 or $15.70.
