I would go for Obtuse from the 120° angle, Acute from the either the 20° and 40°, and scalene since all angles are unequal
Answer:
u = -1
Step-by-step explanation:
5(u+1)-u=3(u-1)+7
distributive property
5u + 6 = 3u - 3 + 7
simplify
5u + 6 = 3u + 4
-3u on both sides
2u + 6 = 4
-6 on both sides
2u = -2
divide 2 on both sides
u = -1
Answer:
4 students
Step-by-step explanation:
As shown in the diagram, let U=[The total number of students questioned]
A=[Those who liked peanut butter ]
B=[Those who liked jam ]
x = those who like both peanut butter and jam.
Also 6 liked neither peanut butter nor jam.
From the diagram we can write the mathematical equation as follow and solve for x
We add x and subtract 30 to both sides.
Therefore 4 students like both peanut butter and jam.
4/9 divide 4 by nine and you get
0.444444444444444444444444444
the 4 goes on forever
The probability that more than one of them are uninsured is the difference between 1 and the probability at one of them is uninsured which is equal to 25%. Thus, to solve for the answer in the question above,
n = 1 - 0.25
Thus, the answer is equal to 0.75 or 75%.
