First find the slope -8 + 2 / -15 + 24 = -6 / 9 = -2 / 3 is the slope. Now use subsitution with an order pair to find the y - intercept. -2 = -2/3(-24) + b, and you find that the y - intercept is -18 ( y - intercept is b). So to find the x - intercept you know that y has to be 0, and create 0 = -2/3x -18, and find that the x-intercept is -27. In order pair form x - intercept would look like (-27,0) and y-intercept would look like (0,-18). Hope this helps.

Answer:

0.118 is the probability someone will spend no more than 30 minutes reading online national news reports.

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 49 minutes

Standard Deviation, σ = 16 minutes

We are given that the distribution of time an individual reads is a bell shaped distribution that is a normal distribution.

Formula:

$z_{score} = \displaystyle\frac{x-\mu}{\sigma}$

P(no more than 30 minutes)

$P( x \leq 610) = P( z \leq \displaystyle\frac{30 - 49}{16}) = P(z \leq -1.1875)$

Calculation the value from standard normal z table, we have,

$P(x \leq 30) = 0.118 = 11.8\%$

0.118 is the probability someone will spend no more than 30 minutes reading online national news reports.

In June, a runner ran a mile in 7:45. In September, the runner ran a mile in 5:51.

1.4 because you divide 7.45 by 5.51 and you get 1.35 which would be rounded to 1.4
