Answer:
Step-by-step explanation:
3(9x - 14/3x + 4 - 1 ≥ 2)
27x - 14x + 12 - 3 ≥ 6
13x + 9 ≥ 6
13x ≥ -3
x ≥ -3/13
Answer:
Approximate probability that
is less than 2 = 0.1515
Step-by-step explanation:
Given -
Mean
= 2.2
Standard deviation
= 1.4
Sample size ( n ) = 52
Let
be the mean of accidents per week at the intersection during one year (52 weeks) .
probability that
is less than 2 =
=
Putting 
=
( Using Z table )
= 0.1515
