Convert the following to standard form <br><br>y=2/5 x - 1/3​
Afina-wow [57]

<u>Given </u><u>:</u><u>-</u>

  • y = 2/5x - 1/3

<u>To </u><u>Find</u><u> </u><u>:</u><u>-</u>

  • To convert the given equation into standard form.

<u>Solution</u><u> </u><u>:</u><u>-</u>

As we know that the standard form of the line is ,

\sf\longrightarrow ax + by + c = 0

So the given equation is ,

\sf\longrightarrow y = 2/5x -1/3

\sf\longrightarrow y = 6x - 5/15

\sf\longrightarrow 15y = 6x - 5

\sf\longrightarrow 6x -15y -5 = 0

<u>Hence</u><u> the</u><u> required</u><u> </u><u>equation</u><u> of</u><u> the</u><u> line</u><u> is</u><u> </u><u>6</u><u>x</u><u> </u><u>-15y-5=</u><u>0</u><u>.</u>

The age of some lecturers are 42,54,50,54,50,42,46,46,48 and 48 calculate the mean age and standard deviation
rjkz [21]

Answer:

Mean age: 48

Standard deviation: 4

Step-by-step explanation:

a) Mean

The formula for Mean = Sum of terms/ Number of terms

Number of terms

= 42 + 54 + 50 + 54 + 50 + 42 + 46 + 46 + 48+ 48/ 10

= 480/10

= 48

The mean age is 48

b) Standard deviation

The formula for Standard deviation =

√(x - Mean)²/n

Where n = number of terms

Standard deviation =

√[(42 - 48)² + (54 - 48)² + (50 - 48)² +(54 - 48)² + (50 - 48)² +(42 - 48)² + (46 - 48)² + (46 - 48)² + (48 - 48)² + (48 - 48)² / 10]

= √-6² + 6² + 2² + 6² + 2² + -6² + -2² + -2² + 0² + 0²/10

=√36 + 36 + 4 + 36 + 4 + 36 + 4 + 4 + 0 + 0/ 10

=√160/10

= √16

= 4

The standard deviation of the ages is 4
