Answer:
Randomly selected adult has an IQ less than 136 is 0.9641
Step-by-step explanation:
It is given that, it is normal distribution with mean 100 and SD as 20.
So, let's use the formula of z-score
z=
For this problem,
x= 136
Plug in this value into the formula
z-score=
=1.8
Now, use z-score table to find the probability
Find the corresponding value for the row 1.8 and the column 0.00, we do get 0.9641
So, Randomly selected adult has an IQ less than 136 is 0.9641
Answer: Y = -10
Step-by-step explanation:
-x + y = -27
-17 + y = -27
+17 +17
Y = -10
You can also check your work by plugging in the X and Y values and it should equal -27 . So -17 + -10 equals -27.

Answer:
20
Step-by-step explanation:
d = √(xb - xa)2 + (yb - ya)2 =
= √(18 - 2)2 + (15 - 3)2 =
= √162 + 122 = √256 + 144 =
= √400
= 20
