Answer:
Step-by-step explanation:
Given that an observation from a normally distributed population is considered "unusual" if it is more than 2 standard deviations away from the mean. There are several contaminants that can harm a city's water supply. Nitrate concentrations above 10 ppm (parts per million) are considered a health risk for infants less than six month of age.
We can say 1.59 and 2.52 if taken average would be the mean
Mean = 2.01
The deviations on either side = 2.52-2.01 = 0.41
This can be taken as 2 std dev
So std dev = 0.205
Hence we can take nitrate concentration is normal with mean = 2.01 and std deviation is 0.205
N(2.01, 0.205)
Answer:
bot 2
Step-by-step explanation:
first find out how many clicks they do in 1 second
16 ÷ 2 = 8
30 ÷ 3 = 10
so know we know that bot 2 clicks 2 more rimes in a second than bot 1
so if we times both the numbers by 10 to find out how many times they click in 10 secs
so bot 1 clicks 80 times
bot 2 clicks 100
I think it is 70 but not sure
Answer:
it is in the tenths place :)
