The average time an individual reads online national news reports is 49 minutes. Assume the standard deviation is 16 minutes and

Olin [163]

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.

Write in point-slope form an equation of the line that passes through the

QveST [7]

Answer:

$y+6 = - 5(x-4)$

Step-by-step explanation:

With the given information, use the point-slope formula $y-y_1 = m (x-x_1)$ to write the equation of the line. Substitute values for the $m$ , $x_1$ , and $y_1$ to find the answer.

$m$ represents the slope, so substitute -5 in its place. The $x_1$ and $y_1$ represent the x and y values of one point the line intersects, so substitute 4 for $x_1$ and -6 for $y_1$ . This gives the following equation:

$y+6 = - 5(x-4)$
