Answer:
x = 50°
Step-by-step explanation:
sum of all angles of a quadrilateral is 360°
so, the other unknown angle be y
=》y + 40° + 110° + 80° = 360°
=》y + 230° = 360°
=》y = 360° - 230° = 130°
and the unknown angle + x = 180°
( because they for linear pair )
so, x + y = 180°
x + 130° = 180°
x = 180° - 130° = 50°
hence, x = 50°
The mean of the set of numbers that are given in this situation regarding the population will be 1809.33.
<h3>How to solve the mean</h3>
The mean of the numbers will be:
= (1,585 + 1,690 + 1,735 + 1,935 + 2,021 + 1,890) / 6
= 1809.33
The median of the numbers will be:
= (1735 + 1890) / 2
= 1812.50
Also, from the complete question, the first quartile will be 1690 and the third quartile is 1935.

Answer:
Step-by-step explanation:
First do 9 times 9 times 9
well, in order to solve this we can put each marble into a fraction.
so for blue it would be 5 over 15 (5/15)
because there are 15 marbles in the bag but only 5 of them are blue!
but if you need a % then just divide the top by bottom
then you get a 33% chance of picking blue! hope this helps!
