Step-by-step explanation:

25/30 divided by 5/5 = 5/6
5+6=11
6-5=1
answer=5/6
Answer:
The sketch is provided in attached file.
0.0228
Step-by-step explanation:
The sketch is made by taking center at µ=80 and the desired probability of the mentioned area is also demonstrates.
The probability randomly selecting a score greater than 100 from this distribution can be calculated as
P(X>100)=P((X-µ)/σ > (100-80)/10)
P(X>100)=P(z>2)
P(X>100)=P(0<z<∞)-P(0<z<2)
Using normal table the probability corresponds to z-score=2 is 0.0228 and the area on the right side of normal curve is 0.5. So,
P(X>100)=0.5-0.4772=0.0228
The probability randomly selecting a score greater than 100 is 2.28%.
X/5 > -2
Multiply 5 on both sides:
x > -10
Draw a graph and draw a line for x > -10
(Look at the attachment below - where the green line is shown make it dotted)
Hope it helped :)
