Answer:
The measure of the fourth angle is 90°.
Step-by-step explanation:
Let x be the measure of the fourth angle.
Given measures of the other angles : 50°,120° & 100°.
<u>Knowledge Required </u>:
The sum of all the interior angles of a quadrilateral is 360°.
Then,
50°+120°+100°+x=360°
⇒x = 360°-270°
⇒x = 90°
.°. x = 90°
Hence, the measure of the fourth angle is 90°.
Answer:
Step-by-step explanation:
Given that X is N(50,3)
So whenever we want score for x, we can convert this to Z and use std normal distribution table.
The formula for conversion is

Using this we can find out the corresponding scores
a) 
Z value = 1 and hence

b) 

c) 
d) 
e) 10th percentile is 
f) This is 99th percentile
=
