Answer:
(2,1) ==> (-2,-1)
(-1,-1) ==> (1,1)
(-2,3) ==> (2,-3)
(-3,3) ==> (3,-3)
Step-by-step explanation:
Answer:
y = -x+2
Step-by-step explanation:
We know the y intercept is 2 ( where it crosses the y axis)
We know two points on the line
(0,2) and (2,0), so we can find the slope
m = ( y2-y1)/(x2-x1_
= (0-2)/(2-0)
= -2/2
= -1
The slope intercept form of the line is
y = mx+b where m is the slope and b is the y intercept
y = -1x +2
y = -x+2
Answer:
a) The required sample size n= 55011,57025
b) The sample size is not practical, because that size is extremely large and would be very costly to collect, normally the size have to be significant but no to large to avoid cost unnecessary
Step-by-step explanation:
Range
⇒ 0,99
Sample size can be determinate using equation:
Using confidence level desired 99% 
= 2,58
Table used :
<em>Confidence 
</em>
<em> 90 % 1,60</em>
<em> 95 % 1,96</em>
<em> </em><em> 99 % 2,58</em>
<em> 99,9 % 3,291</em>
So replacing:
Answer:
64% > 60%
Step-by-step explanation:
Total Units = 9 + 16 = 25 units.
Sarah Receives 16 units out of 25.
Percentage = 16/25 * 100
= 64%
Therefore Sarah received more than 60% of this money and therefore Reece is correct.
