Midnight Mocha is a 24-hour café that specializes in coffee drinks. It has a drive- through that is almost fully automated. Eac

h mug of coffee is dispensed by the automated machinery and should provide exactly 12 ounces. Recently, customers have complained that the cups appear to have too much or too little coffee. Midnight Mocha began a quality control program. Every day for 9 days they sampled 9 cups of coffee. They computed the average amount of coffee for the 9 cups and the range of values. Those values are listed below. 1 2 3 4 5 6 7 8 9 Mean 11.9 12.2 12.0 12.1 11.7 11.9 12.1 12.1 12.0 Range 0.19 0.24 0.18 0.19 0.19 0.18 0.07 0.09 0.07 Use formulas with table values to determine control limits.

1. Events A and B are dependent, P(A)=20%, P(BIA)=25%. What is P(A and B)?
Blizzard [7]
1. Given that e<span>vents A and B are dependent, P(A)=20%, P(BIA)=25%. What is P(A and B)?
P(BIA)=[P(A and B)]/P(A)
it follows then that:
P(A and B)=P(A)*P(BIA)
P(A)=0.2
P(BIA)=0.25
hence
P(A and B)=0.2*0.25=0.05=5%

2. Given that </span><span> P(A) =12%, P(B)=48% and P(A or B)=50%. What is P(A and B)?
P(A or B)=P(A)+P(B)-P(A and B)
but
P(A)=12%, P(B)=48%, P(A and B)=50%
thus
P(A or B)=12%+48%-50%
simplifying the above we obtain:
P(A or B)=60%-50%=10%

Parallel lines have equal slopes.


-x + y = 5


y = x + 5


Slope = 1


y + 5 = 1(x - 2)


y + 5 = x - 2


y = x - 2 - 5


y = x - 7

Can somebody help me with these problems please
mario62 [17]

Answer:

11. A. \frac{12}{13}

12. D. \frac{35}{12}

Step-by-step explanation:

11: Sin is just the side opposite of the angle divided by the hypotenuse of the triangle

Opposite of A = 36

Hypotenuse of the triangle = 39

36/39 = \frac{12}{13}

12. Tan is the side opposite of the angle divided by the side adjacent to the angle

Opposite of C = 35

Adjacent to C = 12

35/12 = \frac{35}{12}

Hope this helps!

I first think that you need to do 64 squared which is 8 then add the other 8 then you have 16 then do 16 square which equals 4 then I think you do 4 x 3 then add 25 then you get your answer..... hopefully
