PART A:
The data is plotted in the graph below. The line best fit is drawn to show the trend of the data. Since the plots form a cluster that follows the line best fit and there are no outliers, the most likely coefficient is 0.94 which is a strong positive correlation.
PART B:
The value of slope between x = 5 and x = 10 is
Slope = (3-1) ÷ (10-5) = 2/5
The slope represents the rate of change of the radius, which is 2/5 for every 5 days
PART C:
The data in the table represents correlation, that the algae grow longer as the days increase. It might not be necessary a causation because the growth of algae doesn't necessarily depend on the number of days.
Step-by-step explanation:
spring water is 2.08/16= 13 cents per ounce
fresh water is 2.40/20= 12.5 cents per ounce
fresh water is .5 cents per ounce less expensive
Hope you can see my working that is attached below.
<span>the side length of the smallest square plate on which a 26-cm chopstick can fit along a diagonal without an overhang is
18.38 cm long (to 2 d.p.) or if you want a more accurate answer you can leave the answer in surds for as

cm
Point A is ( 2 1/4, 1 1/2)
Point B is ( -1 /4, 1 1/2)
Point C is ( 1/4, -2 1/2 )
I hope u get why this is why!
Enjoy the answers

Step-by-step explanation:
radical zeros occur as conjugate pairs, thus
is a zero then - is also a zero
3 + is a zero then 3 - is also a zero
The additional zeros are
- , 3 -
