Given the points P(2,-1) and Q(-9,-6), what are the coordinates of the point on directed line segment PQ that partitions PQ in t

gayaneshka [121]

ANSWER

$( - \frac{23}{5} , - 4)$

EXPLANATION

Given the points P(2,-1) and Q(-9,-6),the coordinates of the point that partition the directed line segment PQ in the ratio 3:2 is given by

$x = \frac{ mx_2+nx_1}{m + n}$

$y= \frac{ my_2+ny_1}{m + n}$

Where m=3 and n=2

$x = \frac{ 3 ( - 9)+2(2)}{3+ 2}$

$x = \frac{ - 23}{5}$

$y= \frac{ 3( - 6)+2( - 1)}{3 + 2}$

$y= \frac{ - 20}{5} = - 4$

The point is

$( - \frac{23}{5} , - 4)$

Nataly_w [17]

Answer:

You will use the z score to find this so need a z score chart.

Step-by-step explanation: Remember to take what you want (35 ounce) minus the mean( 29) then divide by the standard deviation(4). Then you look up this number on the z score chart to find your probability of less than 35 ounces. You could then do the same thing using 34 ounces since your final answer will be between these two numbers.
