Solve the equation for y in terms of x<br><br> 3x-2y=6

Katarina [22]

Answer: 3/2x - 3 = y

Step-by-step explanation:

3x - 2y = 6

+2y = +2y

3x = 6 + 2y

-6 = -6

3x-6 = 2y

/2 = /2

3/2X - 6/2 = y

3/2x - 3 = y

Some please help me in the bottom show me how to do it really confuse ....

Elan Coil [88]

use the equation (y-y)=m(x-x). for example with the first equation: (y-7)=-4(x-2) distribute the slope into the (x-2). this will give you (y-7)=-4x+8. then you add the 7 to both sides to cancel it. this gives you y=-4x+15. hope this helps!! :)

Find the 44th percentile, P44, from the following data! pls help

irina [24]

Answer:

$P_{44} = 29.9$

Step-by-step Explanation:

The 44th percentile, $P_{44}$ , of the given data can be calculated using the kth formula for percentile given as:

$i = \frac{k}{100}(n + 1)$

where,

i = the ranking or the position of the percentile = ?

k = the percentile = 44

n = total number of the given data values = 23

Plug in the values into the formula to find "i"

$i = \frac{44}{100}(23 + 1)$

$i = \frac{44}{100}(24)$

$i = \frac{1,056}{100}$

$i = 10.56$

Since "I", 10.56, is not an integer, round the number down, and round it up to the nearest integer, then look for the position each occupy in the ordered data set, and find their average.

Thus,

$i_{down} = 10.56 = 10$

$i_{up} = 10.56 = 11$

The data occupying the 10th position on the data set = 28.7

11th = 31.1

$P_{44} = \frac{28.7 + 31.1}{2} = \frac{59.8}{2}$

$P_{44} = 29.9$
