Answer:
y = 9x + (-7) should be the answer
Answer:
The answer is 5 people
Step-by-step explanation:
This is because 30/6 equals 5
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:
The top one I'm pretty sure.
