the forecast calls for a 30% chance of snow today and a 40% chance of snow tomorrow. what are the chances it will rain two days
1 answer:
Answer:
The chances it will rain two days in a row is 12%
Step-by-step explanation:
The forecast calls for a 30% chance of snow today
So, chance of snowfall today = 30% = 0.3
A 40% chance of snow tomorrow.
So, chance of snowfall tomorrow= 40% = 0.4
The chances it will rain two days in a row =
=
So, percent it will rain two days in a row =
Hence the chances it will rain two days in a row is 12%

Answer:
The range is:
{-4, 1, 2, 5, 8}
Step-by-step explanation:
Given the function
- We know that the domain of a function is the set of input or argument values for which the function is real and defined.
As the domain interval -2 ≤ x ≤ 2
i.e. the values in the domain = {-2, -1, 0, 1, 2}
- We also know that the range of a function is the set of values of the dependent variable for which a function is defined.
As the domain interval -2 ≤ x ≤ 2
Putting all the x-values in the domain interval in the function
so
putting x=-2 in the function
putting x=-1 in the function
putting x=0 in the function
putting x=1 in the function
putting x=2 in the function
Thus, when we put the domain values, the corresponding range values are:
x y
-2 -4
-1 1
0 2
1 5
2 8
Therefore, the range is:
{-4, 1, 2, 5, 8}
We have the expression:
And we need to solve this for x.
Let's solve this expression and then see which of the options is the correct one.
The first step to solve this is that we need for the two sides of the equation to have the same base. (the number 5 on the left side is the base, so we need to also have a 5 as the base on the right side).
We do this by noting that:
We know that 25 is equal to 5 squared (because 5x5 is 25)
So the first step is to substitute 25 for 5 squared:
Since we have the same base on both sides (5), we follow the rule:
• If we have the same base on both sides of an equation, the exponents have to be equal
Thus, the second step to solve is to equal the exponents:
Finally, to solve this equation for x, we just need to add 1 to both sides to get rid of the -1 on the left side:
And the third step is:
As we can see, these three steps are represented in the third option In which we get the same result of x=3.
Answer: x=3
