Rae planted a square garden that covers an area of 200 ft.² how many feet of fencing does he need to surround the garden

inessss [21]

To find this, first we have to find the square root of 200, which is about 14.14

Now we multiply 14.14 * 4 = 56.56

So Rae will need about 56.56 feet of fencing to surround the garden.

Answer:

a) $y=\frac{28}{75}(x-1900)+47.3$

b) 86.5 years

Step-by-step explanation:

All values are rounded to 2 decimal places

a) We can find line by using y =mx+b

$y=mx+b\\m=\frac{y^{2}-y^{1} }{x^{2}-x^{1}}\\m=\frac{69.7-47.3}{1960-1900} \\m=\frac{22.4}{60} \\m=\frac{28}{75}\\c=y-intercept\\y-intercept=47.3\\y=\frac{28}{75} (x-1900)+47.3$

Therefore the line of best fit is $y=\frac{28}{75}(x-1900)+47.3\\$

b) We can do this by using the formula of the best fit line to estimate the life expectancy of someone born in 2005

$y=\frac{28}{75}(x-1900)+47.3\\y=\frac{28}{75}(2005-1900)+47.3\\y=\frac{28}{75}\times105+47.3\\y=86.5$

Therefore the estimated life expectancy of someone born in 2005 is 86.5 years

PS. Please give brainliest answer this was a lot of working out

How do I study for a big math test? any tips on how to study I'm a visual learner.

Nastasia [14]

Honestly? Just review your notes and try to work out the problems yourself before taking a look at the answer. You can also google specific topics that the test will cover and try the practice problems.
