Answer:
a) 2 accidents per day
b) .7071 accidents
Step-by-step explanation:
a) The mean is the sum of each possible number of accidents multiplied by its respective probability. So,
E(x) = (0)(.1) + (1)(.2) + (2)(.45) + (3)(.15) + (4)(.05) + (5)(.05) = 2
b) The variance V(x) = E(x^2) - E(x)^2, and the standard deviation is the square root of the variance. So,
V(x) = E(x^2) - (2)^2
= (0)(.1) + (1)(.2) + (4)(.45) + (9)(105) + (16)(.05) + (25)(.05) - 4 = 0.5
sqrt(0.5) = .7071
Answer:
JK = 2.4
Step-by-step explanation:
Since the figures are similar then the ratios of corresponding sides are equal, that is
= 
, substitute values
= 
( cross- multiply )
3JK = 7.2 ( divide both sides by 3 )
JK = 2.4
Answer:2
Step-by-step explanation:It’s like doing 6 minus 4. Then use the symbol from the largest number
It is (b-5)+6
hope this helps
