Answer:
The angles are 15 degrees, 45 degrees and 120 degrees
Step-by-step explanation:
The triangle has three three sides and three angles. The sum of the angles in a triangle is 180 degrees
Let x = the size of the largest angle of the triangle
Let y = the size of the middle angle of the triangle
Let z = the size of the smallest angle of the triangle.
x + y + z = 180 - - - - -- - - - - - - 1
The size of the largest angle is eight times the size of the smallest angle.
This means
x = 8z
The size of the middle angle is triple the size of the smallest angle. This means
y = 3z
Put x = 8z and y = 3z in equation 1
8z + 3z + z= 180
12z = 180
z = 180/12 = 15
x = 8z = 8×15 = 120
y = 3z = 3 × 15 = 45
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.
Answer:
0.318
Step-by-step explanation:
To solve this problem you have to know how to how to get rid of the lowest properties first like 12.5t for example subjtract that from 65t and you will get 52.5. Then your gonna want to subtract 9 from 14 and that will give you 5. Lastly, your going to divide by 52.5 by 5 and your answer will be 0.095
7(x+2)=77
7x+14=77
-14=-14
7x=63
