Answer:
E 0.923
Step-by-step explanation:
The Z score is a measurement used in statistics to determine the relationship between a value and a mean of a group of values measured as standard deviation from the mean. The z score (z) is given as:
, Where μ is the mean, σ is the standard deviation and x is the value.
Given that:
σ = 7, μ = 80 and x = 90
From the normal distribution table, P(X < 90) = P(z < 1.43) = 0.923
Answer:
55998000
Step-by-step explanation:
When you take 5 time 3 you get 15
Then you take 15 and times that by 17 and get 225
then you take that and multiply that to 200 and get 5100
Finally you multiply 5100 to 1098 and get 5598000
