Answer:
well you find. out how many all of them measure. and add them and then that answer multiply of the main number
Step-by-step explanation:
first add up all of the lengths and then find that answer multiply it to the main number and then you will get your anwer it's a 2 step problem
For this case, the first thing you should do is to know the following transformation:
pi radians = 180 degrees
Applying the transformation we have:
(13pi / 6) * (180 / pi) = 390 degrees
Then, in quadrant 1 we have:
390 - 360 = 30 degrees
Answer:
13 pi / 6 as a function of an angle in quadrant i is:
30 degrees
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}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20Of%5Ctext%7B%20the%20total%20production%3B%7D%20%5C%5C%20A%3D55%5Ctext%7B%20%5C%25%7D%3D0.55%20%5C%5C%20B%3D25%5Ctext%7B%20%5C%25%7D%3D0.25%20%5C%5C%20C%3D20%5Ctext%7B%20%5C%25%7D%3D0.20%20%5Cend%7Bgathered%7D)
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}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20A%3D3.5%5Ctext%7B%20%5C%25%7D%3D0.035%20%5C%5C%20B%3D4.5%5Ctext%7B%20%5C%25%7D%3D0.045%20%5C%5C%20C%3D5.5%5Ctext%7B%20%5C%25%7D%3D0.055%20%5Cend%7Bgathered%7D)
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}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20P%5Clbrack%20defective%5Crbrack%3D%280.55%5Ctimes0.035%29%2B%280.25%5Ctimes0.045%29%2B%280.20%5Ctimes0.055%29%20%5C%5C%20P%5Clbrack%5Ctext%7Bdefective%5Crbrack%7D%3D0.01925%2B0.01125%2B0.011%20%5C%5C%20P%5Clbrack%5Ctext%7Bdefective%5Crbrack%7D%3D0.0415%20%5Cend%7Bgathered%7D)
ANSWER:
The probability that the item is defective would be 0.0415
Answer:
The chance of losing five games in a row is 0.8 × 0.8 × 0.8 × 0.8 × 0.8 = 0.85 = 0.328. The chances of that not happening is 0.672. That’s the chance that you will win at least one game out of the five. 67.2%.
Much later:
I just noticed that this question had details that are now in a comment:
I already know the technique: 1 - (0.8)^5
But I wanted to know how to do it in other ways
Sadly Quora no longer shows the question details below the question the way it used to. My answer explained it in the way the asker indicated in their comment that they already knew and they wanted something different. Sorry about that. At this point, I’m not inclined to try figuring out other ways (enumerating all the sequences, for example, and tallying the probabilities).
Step-by-step explanation:
A standard deck of cards has 52 cards.....there are 4 aces.
probability that u dont choose an ace :
cards that are not aces / total cards = 48/52 which reduces to 12/13
