Step-by-step explanation:
multiply it
x²-3x+3x-9=0
x²-9=0
x²=9
square root both side we get
x=3
Answer:
Step-by-step explanation:
We can calculate this confidence interval using the population proportion calculation. To do this we must find p' and q'
Where p' = 14/100= 0.14 (no of left handed sample promotion)
q' = 1-p' = 1-0.14= 0.86
Since the requested confidence level is CL = 0.98, then α = 1 – CL = 1 – 0.98 = 0.02/2= 0.01, z (0.01) = 2.326
Using p' - z alpha √(p'q'/n) for the lower interval - 0.14-2.326√(0.14*0.86/100)
= -2.186√0.00325
= -2.186*0.057
= 12.46%
Using p' + z alpha √(p'q'/n)
0.14+2.326√(0.14*0.86/100)
= 0.466*0.057
= 26.5%
Thus we estimate with 98% confidence that between 12% and 27% of all Americans are left handed.
Some of the factors that can make a reunion unhappy or bittersweet are:
- Death of a mutual.
- Personal tragedies, etc.
<h3>What is Reunion?</h3>
This refers to the situation where two or more people meet each other again after a long time of being apart.
We can note that sometimes, a reunion is happy, other times, it is bittersweet or unhappy as either some good thing or unfortunate event has occurred during the period spent apart from each other.
Please note that your question is incomplete so I gave you a general overview to help you get a better understanding of the concept.

Slope = m = y2-y1/x2-x1
= 5-(-3)/4-(-2)
m=8/6
m=4/3
so eq of line we select any of one point . i select (4,5)
y - y1 = m(x-x1)
y- 5 = 4/3 (x-4)
3y -15 = 4x-16
4x-3y = 1
