Answer:
Maybe the answer must be 90°
Answer:
The value of K is 5
Step-by-step explanation:
I reversed it.
The tiny squares means 90⁰, so 90+49=139
All of these angles add up to 180⁰
So 180-139=41
The k equation equals 41⁰, so reverse it to find answer
41-1=40
40÷8=5
The z-score is calculated by the formula (x - mu)/sigma, where x is the value, mu is the mean, and sigma is the standard deviation.
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
