Answer:

a) The Mean of the water levels for the week (μ) = 6.657

b) The Median of the water levels for the week = 6.6

c) Mode = 6.8

Step-by-step explanation:

<u><em>Step(i):-</em></u>

<em>Given that the data per one week</em>

<em>6.5,  6.8 , 7.2  ,6.8  ,6.6  ,6.3 , 6.4</em>

<em>we have to find the mean of the given data</em>

<em>Solution:-</em>

<em>Mean = ∑x /n</em>

<em />Mean = \frac{6.5+6.8+7.2+6.8+6.6+6.3+6.4}{7}<em />

<em>Mean = </em>\frac{46.6}{7}<em />

<em>Mean(μ) = 6.657</em>

<em>The Mean of the water levels for the week (μ) = 6.657</em>

<u><em>Step(ii):-</em></u>

Given that the data per one week

6.5,  6.8 , 7.2  ,6.8  ,6.6  ,6.3 , 6.4

we have to find the Median of the given data

A median is the center value of a  given  data when arranged in an order

6.3  6.4  6.5 <em> 6.6</em>  6.8  6.8 7.2

The Median = middle of the given data

The Median = 6.6

<u><em>Step(iii):-</em></u>

Given that the data per one week

6.5,  6.8 , 7.2  ,6.8  ,6.6  ,6.3 , 6.4

we have to find the Mode of the given data

Mode = Value repeated the most number of times

The value 6.8 repeated two times

∴ Mode = 6.8

Write an equation that is perpendicular to y= 1/2x+5 and passes through (4,8)
goblinko [34]

Answer:

y = -2x + 16.

Step-by-step explanation:

The slope of the perpendicular line = -1 / slope of the given line

= -1 / 1/2 = -2.

Using the point slope form of the equation of a straight line:

y - y1 = m (x - x1)

y - 8 = -2(x - 4)

y - 8 = -2x + 8

y = -2x + 16  is the required equation.
