Step-by-step explanation:
Answer:the system has no solutions
Step-by-step explanation:
Answer: The equation is of line "b"
Step-by-step explanation:
First we find the slope of the given line by using slope intercept form.
Converting the equation into slope intercept form
Divide both side by 5 we get
On comparing with
We get slope
as the slope of line is negative therefore the line will be either line "b" or line "d"
As line "b" pass from (0,2)
On putting point in given equation we get
Which is equal to RHS of the line
Therefore the given equation is of line "b"
Now putting point (0,-2)
We get
Which is not equal to RHS and therefore line "d" is not the required line
Therefore the given equation is of line "b"
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 .
