Answer:

97.73%

Step-by-step explanation:

Mean (μ) = 170

Standard deviation (σ) = 5

Assuming a normal distribution, for any observed value, X, the z-score is determined by:

z=\frac{X-\mu}{\sigma}

For X = 180:

z=\frac{180-170}{5}\\ z=2

A z-score of 2 corresponds to the 97.73-th percentile of a normal distribution.

Therefore, the percentage of data that is less than 180 is 97.73%.

Write the slope intercept form of the equation of the line that passes through the point (4, 8) and has a slope of -2.
zhuklara [117]

The equation of the line is y = -2x + 16 which passes through the point (4, 8) and has a slope of -2.

<h3>What is a linear equation?</h3>

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

It is given that:

The line that passes through the point (4, 8) and has a slope of -2.

On comparing the standard equation:

y = mx + c

Here m is the slope of the line and c is the y-intercept.

m = -2

y = -2x + c

Plug x = 4 and y = 8

8 = -2(4) + c

c = 16

y = -2x + 16

Thus, the equation of the line is y = -2x + 16 which passes through the point (4, 8) and has a slope of -2.

Answer:

A) rate of change would be dividing the number of songs wanted (150) by the number of weeks downloading (5)

150/5 = 30

 since the total quantity wanted is becoming less every week the rate of change would be negative so it becomes -30

Initial value is 150, which is the total number of songs they want

             B) rate of change would be dividing the number of songs wanted (150) by the number of weeks downloading (5)

150/5 = 30

 since the total quantity wanted is becoming less every week the rate of change would be negative so it becomes -30

Initial value is 150, which is the total number of songs they want
