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
Hey there! I'm happy to help!
We have the number -28 and we are subtracting 3 from it. This means we are going even further into the negatives, so it is -31.
Have a wonderful day! :D
<span>We will consider that the average volume of a cup is 200 ml, that is 0,2 liters.
That means 1 liter of liquid in cups is:
1 liter * 0.2 cup/liter = 5 cups
Then the equivalent of recommended liquid in number of cups is:
2.2 litres * 5 cup / liter = 11 cups of 200 ml each.</span>
