WILL GIVE BRAINLIEST The table shows the minimum wage rates for the United States during different years. (image of table is attatched)
Using technology (graphing calculator or Excel spreadsheet), Write the least squares regression equation that models the data. Let x = time in years since 1900 and let y = minimum hourly wage.
Use the equation to estimate the minimum hourly wage of a U. S. worker in 2025. Show your work.

ŷ = 0.12587X - 246.27846

8.61

Step-by-step explanation:

Given the data :

1978

1979

1980

1990

1991

1996

1997

2007

2008

2009

Minimum hourly wage (y)

2.65

2.90

3.35

3.80

4.25

4.75

5.15

5.85

6.55

7.25

Using the online regression calculator :

The linear regression equation / model is in the form:

y = mx + c

Where y = predicted or dependent variable

m = gradient or slope of the line

c = intercept, where the line crosses the x - axis

The model equation obtained is :

ŷ = 0.12587X - 246.27846

Where

0.12587 = slope of the line

246.27846 = intercept

To determine the minimum hourly wage in 2025:

Substitute x = 2025 in the model equation obtained

ŷ = 0.12587(2025) - 246.27846

ŷ = 254.88675 - 246.27846

ŷ = 8.60829

ŷ = 8.61

18.8 cubic inches.

step-by-step explanation:

volume of a cone = πr²h

r = 1.5 inches

h = 8 inches

pi = 3.14

volume of our cone = × 3.14 × 1.5² × 8 = 18.84 square inches

or equals to 18.8 square inches rounded up to nearest tenth.

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
