It is b I seen it on the test yesterday on Plato
Answer: Slope = -2.667/2.000 = -1.333
x-intercept = 5/4 = 1.25000
y-intercept = 5/3 = 1.66667
Step-by-step explanation: Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is 1.667 and for x=2.000, the value of y is -1.000. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of -1.000 - 1.667 = -2.667 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)
Answer:
875 dollars
Step-by-step explanation:
You work 7 hours per day and paid 25 per hour so:
7×25=175
So you get paid 175 dollars per day, but we want 5 days so:
175×5=875
Answer:
(b) 0.00640
Step-by-step explanation:
Let
P(A|F) = The probability of bags that contain forbidden material trigger an alarm = 0.97 or 97%
P(A| not F)= The probability of bags that do not contain forbidden material also trigger the alarm= 0.15 or 15%
P(F) = the probability that a bag contain forbidden material = 0.001
P(not F) = the probability that a bag does not contain forbidden material = 0.999
Then P(A)= P(F) × P(A|F) + P(not F) × P(A| not F) = 0.001×0.97 + 0.999×0.15 = 0.15082
Then the probability that a bag that triggers the alarm will actually contain forbidden material =
= ≈ 0.0064
I’m not sure but I think it can fill 85 bottles. Because you divide 1280 by 15 and you get 85.33 which is rounded to 85.
