The probability that it'll rain tomorrow in Ohio is 30%

VLD [36.1K]

It raining in Alaska and raining in Ohio are independent events. One does not control the other or affect the other in any way.

For two independent events (let's call them A and B), the Probability of A and B both occurring is given by P(A and B) = P(B) x P(B).

For this problem, let A = rain in Ohio and B= rain in Alaska.

P(A and B) = P(A) x P(B)
$\frac{12}{100} =(P(A))( \frac{3}{10} )
$
$( \frac{12}{100}) ( \frac{100}{30} )=P(A)$
$P(A)= \frac{12}{30}= \frac{2}{5}$

Answer:

The equation of the regression line for the following data is:

y=2.4x+120.1

Step-by-step explanation:

We are given a set of data values in table form as:

Day(x) Number of visitors(y)

1 120

2 124

3 130

4 131

5 135

6 132

7 135

Hence, when we draw a scatter plot with the help of these data points using the linear regression calculator we see that the regression line is a line with y-intercept as (0,120.1) and x-intercept as (-50.04,0)

Hence, the regression line for the following data is:

y=2.4x+120.1
