Answer:
If I'm not wrong, I think it's 0.5
Step-by-step explanation:
This is because if the false posative rate 23% and there are 2 people, you would find 23% of 2, which gives you 0.46. Rounded, this is 0.5. So there is a 0.5% probability that more than 0 valenteers will get false posative results.
Answer:
t>-2
Step-by-step explanation:
-6t < 12
Move the -6 over to 12 and divide
And change the sign after u divide
Answer:
rate of the current = 2 km/hr
Step-by-step explanation:
d = rt
Let c = rate of the current
Rate of boat downstream = 10 + c
Time going downstream = 24/(10 + c)
Rate of boat upstream = 10 - c
Time going upstream = 24/(10 - c)
Since the total time is 5 hr, then
24/(10 + c) + 24/(10 - c) = 5
24(10 - c) + 24(10 + c) = 5(10 + c)(10 - c)
240 - 24c + 240 + 24c = 500 - 5c^2
480 = 500 - 5c^2
5c^2 = 20
c^2 = 4
c = 2 or -2
Since a rate cannot be negative, the rate of the current = 2 km/hr
16(1 - m) = 9 - 2m
16 - 16m = 9 - 2m | - 9
16 - 9 - 16m = 9 - 9 - 2m
7 - 16m = -2m | + 16m
7 - 16m + 16m = -2m + 16m
7 = 14m | : 14
7 : 14 = 14m : 14
7/14 = m
m = 7/14
m = 1/2
