The probability that student scored more than 850 we shall proceed as follows:
z=(x-μ)/σ
where:
x=850
μ=750
σ=50
thus
z=(850-750)/50
z=2
thus
P(x>850)=1-P(x<850)=1-P(z<2)=1-0.9772=0.0228
Answer: P(x>850)=0.0228
Answer:
I think number 2 is the answer, but 4 could be the answer.

Step-by-step explanation:
An arithmetic sequence has a common difference between adjacent terms. Here, the differences are ...
The differences are different, not common, so this is NOT an arithmetic sequence.
