Answer:
NOR = 126.6
Step-by-step explanation:
one full circle would have 360 degrees
so we can make an equation that shows all of our angles adding up to 360:
NOQ + QOR + NOR = 360
we know that NOQ is 147.7
we know that QOR is 85.7
substitute these into our equation:
147.7 + 85.7 + NOR = 360
add like terms:
233.4 + NOR = 360
subtract 233.4 from both sides:
NOR = 126.6
Answer:
1. 0.33 2. 0.16 3. o.11
Step-by-step explanation:
Answer:
For x>0
-x < 0
0-x < 0 +0 = 0
So 0-x < 0
10(0-x) < 10*0
10(0-x) < 0
10(-x) <0
Step-by-step explanation:
Answer:
or .
Step-by-step explanation:
We have been given that a normal distribution has μ=80 and σ=10. We are asked to find the the probability of randomly selecting a score greater than 85 from this distribution.
First of all, we will find the z-score corresponding to normal score 85 as:
Upon substituting our given values in z-score formula, we will get:
Now, we need to find for the probability of randomly selecting a score greater than 85 from this distribution.
Using formula , we will get:
Therefore, the probability of randomly selecting a score greater than 85 from this distribution would be 0.30854 or .
