Step-by-step explanation:
the probability of filling a cup between 26 and 31 ounces is 0.7745
<u>Step-by-step explanation:</u>
Step 1: Sketch the curve.
The probability that 26<X<31 is equal to the blue area under the curve.
Step 2:
Since μ=28 and σ=2 we have:
P ( 26<X<31 ) = P ( 26−28 < X−μ < 31−28 )
⇒ P ( (26−28)/2 < X−μ/σ < (31−28)/2 )
Since Z= x−μ/σ , (26−28)/2 = −1 and (31−28) / 2 = 1.5 we have:
P ( 26<X<31 )=P ( −1<Z<1.5 )
Step 3: Use the standard normal table to conclude that:
P ( −1<Z<1.5 )=0.7745
Therefore , the probability of filling a cup between 26 and 31 ounces is 0.7745
Answer:
A and B
Step-by-step explanation:
When rotating a point (or any shape around a certain point), none of the diameters of the shape will change. So for example, with this circle, when you rotate it around a point, the radius and circumference will not change because it has just rotated. It wont be on the x-axis though because point P is not on the x-axis an it is being rotated 180 degrees about point P. Just know that when you are rotating, nothing about the shape changes, all angles or measurements will be the same, it is just moving to a different place.
Hope this helped ^-^
