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:
y = 2
Step-by-step explanation:
x= -1+y
2x-y=0
2(-1+y)-y=0
-2+2y-y=0
-2+y=0
-2+2+y=0+2
y=2
