The data in this table represents a linear function. What is the slope of this line?
2/7
1/3
3
7/2

3

Step-by-step explanation:

X = 5 – 2 = 3

Y = 16 – 7 = 9

Equation of the line:

y = 3x + 1

When x=0, y = 1

When y=0, x = -0.33333333333333

15.5

step-by-step explanation:

5

∑

n = 1

substitute n = 1, 2, 3, 4, 5 and sum the terms

= + + + 2² + 2³

= 0.5 + 1 + 2 + 4 + 8

= 15.5

the total estimated nappy use.=10,500,000

step-by-step explanation:

given that on an average the average baby uses 3528 napkins.

in a particular year 2014, the number of births were 299697 in new south wales.

rounding off the number of births to the nearest hundred thousand we have

no of birtsh = 300000

also rounding off the average usage to nearst thousand we get

average use of a baby = 3500

hence total number of nappy estimated to be used = 3500x300000

= 10,500,000

answer is 10,500,000 nappies
