Answer:
The probability is 0.05
Step-by-step explanation:
Since the event of a major earthquake is independent of other major earthquakes, the problem is quite simple. We know that the probability an event like this occurs every ten years is 0.1.
Using this, we can calculate the probability of it happening any one year to be
= 0.01
We can multiply this probability by the number of years.
Total number of years: 12 - 7 = 5
Probability the earthquake happens in these 5 years :
= 0.05
Angle two is 39° because of the law of congruent angles within two parallel lines
Answer:
C
Step-by-step explanation:
To solve it will be easier to turn 7 into a rational number with the same denominator as 5/7
To do this make ratios
![\frac{7}{1}=\frac{x}{7}](https://tex.z-dn.net/?f=%5Cfrac%7B7%7D%7B1%7D%3D%5Cfrac%7Bx%7D%7B7%7D)
Now solve for x
x = 49
This means that the fraction will be 49/7
This can also be written as ![6\frac{2}{7}](https://tex.z-dn.net/?f=6%5Cfrac%7B2%7D%7B7%7D)
