Answer:
y = 40
Step-by-step explanation:
The sum of the angles of a triangle are 180 degrees
y+10 + 2y +50 = 180
3y+60 = 180
Subtract 60 from each side
3y+60-60 = 180-60
3y = 120
Divide each side by 3
3y/3 = 120/3
y = 40
Answer:
The growth rate is 0.6
The growth factor is 1.6
Step-by-step explanation:
Generally, the exponential equation can be written as;
y = a(1 + r)^x
Where a is the initial value of 100
r is the growth rate
So let us form equations;
160 = 100(1 + r)^1 •••••(i)
Also;
256 = 100(1 + r)^2 •••••••(ii)
Divide equation ii by i
256/160 = 1 + r
1.6 = 1 + r
r = 1.6-1
r = 0.6

Step-by-step explanation:
Theoretical probability is the actual chance of something happening based on raw numbers.
For example: The theoretical probability of tails on a coin flip is 1/2 or 50%. If you flipped a coin, you would expect 50% to be heads, 50% to be tails.
However, since this almost never happens, experimental probability is used to describe the actual results.
For example: If you flip the coin 50 times and 23 are tails, 27 are heads, then the experimental probability is 46% for tails and 54% for heads.
I'm always happy to help :)
