Probability of not witnessing a major tornado hit over the next ten years would be derived from historical data based on frequency of such events. Probability is a measure of uncertainty and these estimates can change as more information becomes available. Actual probability calculations can involve complex concepts such as Poisson distributions and conditional probabilities.
The question asks for the probability of not witnessing a major tornado hit over the next ten years. Probability in this context would typically be derived from historical data on frequency of such events. The data provided seems unrelated, so I'll provide a hypothetical example instead. If historical data shows that the state gets hit by a major tornado every 20 years on average, you could argue there's a 50% chance (1 out of 2 decades) that the state will not be hit by a major tornado in the next ten years.
However, keep in mind that probability is a measure of uncertainty, not certainty. Probabilities are estimates based on what we currently know and can change as more information becomes available. For example, if climate change leads to more severe weather events, the chance of a tornado might increase.
This is a simplified model and actual probability calculations can be much more complex, involving things like Poisson distributions and conditional probabilities which are often used in analyses of rare events such as natural disasters.

7x+6y=7
Is (5,1) a solution of the system?
Answer:
{x = 1/7,y = 1
Step-by-step explanation:
Solve the following system:
{-5 y = -5 | (equation 1)
{7 x + 6 y = 7 | (equation 2)
Swap equation 1 with equation 2:
{7 x + 6 y = 7 | (equation 1)
{0 x - 5 y = -5 | (equation 2)
Divide equation 2 by -5:
{7 x + 6 y = 7 | (equation 1)
{0 x+y = 1 | (equation 2)
Subtract 6 × (equation 2) from equation 1:
{7 x+0 y = 1 | (equation 1)
{0 x+y = 1 | (equation 2)
Divide equation 1 by 7:
{x+0 y = 1/7 | (equation 1)
{0 x+y = 1 | (equation 2)
Collect results: Answer: {x = 1/7,y = 1
Answer:
No
Step-by-step explanation:
Which of the following inequalities matches the graph?
Looking at the graph the y values does not change, it stays at zero
The shaded area are the numbers under O
This means the answer is y ≤ 0
Hope it helps

Answer:
x=-3
Step-by-step explanation:
(3x-15)/2 = 4x
Multiply each side by 2
(3x-15)/2 *2= 4x*2
3x-15 = 8x
Subtract 3x from each side
3x-15-3x = 8x-3x
-15 = 5x
Divide each side by 5
-15/5 = 5x/5
-3 =x
Answer:
X=-3
Step-by-step explanation:
(b) 4
(c) 8
(d) -8
Answer:
D) -8
Step-by-step explanation:
If you add a positive and a negative, you end up subtracting. If your sum is lower than any of the numbers you are adding together, then there is a negative. In this case, your only negative number is -8, but if there were others, you could find this equation by doing negative six minus two (because the equation was originally addition, it would still be subtraction to check your work or find the answer in this case.)
Hopefully you find this useful :)
Answer: -8
Step-by-step explanation: lets take the unknown number as x,
so we have, 2 + x= -6
by using transposition method, x= -6-2( positive becomes
negative when transpositioning)
so, x= -8
Answer:
2.700 × 10-7
Step-by-step explanation:
Answer: 2.7*10^-4
step by step explanation:
1. Make the number a new number between 1 and 10
More Icon
Move the decimal point to make 0.00027 a new number between 1 and 10. Because our original number is less than one, we move the decimal point to the right. Drop any zeroes in front of the number. Keep track of how many times we move the decimal point.
0.00027 -> 2.7
Our new number is 2.7. We moved the decimal point 4 times.
2. Define the power of 10
More Icon
Because our original number was less than one, the exponent defining the power of 10 is negative. Remember, we moved the decimal point 4 times, so the exponent is negative 4
10^(-4)
3. Final result
2.7*10^(-4)
