Answer:
solved
Step-by-step explanation:
Mean = 12
SD = 2
Answer to part 2) Less than 7 months
P(x < 7)
P(x < 7) = P(z < (7-12)/2) = P(z < -2.5)
This probability can be obtained by referring to the Z table
Thus P(x < 7) = 0.0062
1) Between 7 and 12 months
P(7 < x < 12) = P( x< 12) - P(x < 7)
We have P(x < 12) = 0 ......[because mean = 12]
and P(x < 7) = 0.0062 ...[this we got is part a]
Thus on plugging these values we get
P( 7 < x < 12) = 0.5 - 0.0062 = 0.4938
Thus P(7 < x < 12) = 0.4938

Answer:
Step-by-step explanation:
-0.59x+0.29=7.2
-0.59x+0.29-0.29=7.2-0.29
-0.59x=7.2
divide both sides by -0.59
x=−
11.7118644
that can be rounded to x= -11.7
Answer:
Irrational numbers can look like fractions: 
Irrational numbers have never ending decimals. Pi and e are also irrational numbers.
Answer:
4) Alternate angles
Step-by-step explanation:
Alternate angles are on the opposite corners of the line of the angle, and 10 and 14 are on opposite corners, so that makes them alternate angles. I hope this helped you!
