Probability that it will rain on the first day and be clear (not rain ) on the next two days is 0.1719 .
<u>Step-by-step explanation:</u>
We are given that there is a 23% chance it will rain on any day, we need to find what is the probability that it will rain on the first day and be clear (not rain ) on the next two days . Let's do it step by step:
Probability for first day is to rain i.e. .
Probability for second day is to not rain i.e. .
Probability for third day is to not rain i.e. .
Now, Probability for occurrence of these 3 events simultaneously is :
⇒
⇒
⇒
∴ Probability that it will rain on the first day and be clear (not rain ) on the next two days is 0.1719 .
Answer: $375
Step-by-step explanation:
Given : The probability of winning $100 : P(100)= 0.25
The probability of winning $200 : P(200)= 0.50
The probability of winning $1000 : P(1000)= 0.25
Now, the the expected value of that lottery ticket is given by :-
Hence, the the expected value of that lottery ticket =$375
Answer:
The y-intercept of the line that passes through the point (3, -6) and which has a slope of 4 is -18.
Step-by-step explanation:
We represent the straight line by using this formula from Analytical Geometry:
Where:
- Independent variable, dimensionless.
- Dependent variable, dimensionless.
- Slope, dimensionless.
- y-Intercept, dimensionless.
Now we clear the y-intercept:
If we know that , and , the y-intercept of the line is:
The y-intercept of the line that passes through the point (3, -6) and which has a slope of 4 is -18.
Answer:
(-2, -3)
Step-by-step explanation:
The middle of the point. It covers two blocks so find the middle.
Or you can use the midpoint formula
