Answer:
50
Step-by-step explanation:
The sum of the angles of a triangle add to 180 degrees
A + B + C = 180
2x-10 + 70+ x+30 = 180
Combine like terms
3x +90 = 180
Subtract 90 from each side
3x+90-90=180-90
3x= 90
Divide by 3
3x/3= 90/3
x=30
We want to find angle A
A = 2x-10
=2*30 -10
=60-10

Step-by-step explanation:
By Geometric mean property:
Step-by-step explanation:
a)State the random variable.x = number of brown M&Ms in the milk chocolate box.
(b)Argue that this is a binomial analysis.
The binomial analysis includes the following characteristics: 1.Fixed number of measurements.
2. The experiments are autonomous.
3. There are just two results.
4. The expectation of victory will not shift from court to court.
This is a binomial experiment since the number of experiments is set and the measures are independent of each other. In fact, there are only two results – brown M&Ms or not.
