Convert the angle to a decimal in degrees <br> 60 degree 19 ‘39”

7nadin3 [17]

bearing in mind that there are 60 minutes in 1 degree, and 60 seconds in 1 minute.

60°19'39"

so 39 seconds is really 39/60 minutes, or 0.65 minutes

so 19'39" is really 19.65'.

since there are 60 minutes in 1 degree, then 19.65' is really 19.65/60 degrees, or 0.3275°.

60°19'39" is then 60.3275°.

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
