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:
1/4, 1/8, 1/16
i don't know this is my guess but these are small and close to zero
The answer is 1:60 no it’s wrong
Answer:
12.025
Step-by-step explanation:
h=v/(π*r square)
divide the volume of a cylinder by the amount of the radius squared multiplied by π(pi)
340÷(π×3square)
giving you 12.025
(original in calculator=12.02504014)
but it is 12.025
