3 The scatterplot shows the time it takes for a new hot
plate to boil various amounts of water, and one lab
group's attempt at a line of best fit.
What feedback should another lab group give during a
peer review of the work?
Boiling Water Test
35
O The line of best fit is reasonable because it does not
go through any points.
O The line of best fit is reasonable because it goes
through the largest cluster of points.
O The line of best fit is not reasonable because it does
not go through any points.
The line of best fit is not reasonable because it has
more points below it than above it.

step-by-step explanation:

the solution of the equation is 2.23 ⇒ answer b

step-by-step explanation:

* lets revise the meaning of exponential function

- the form of the exponential function is y = ab^x, where a ≠ 0, b > 0 ,  

  b ≠ 1, and x is any real number

- it has a constant base b

- it has a variable exponent x

- to solve an exponential equation, take the log or ln of both sides,  

  and solve for the variable

* lets solve the problem

∵

- the base is 7 and the exponent is x

- insert ㏑ in both sides

∴

- use the rule

∴ x ㏑(7) = ㏑(77)

- to find x divide both sides by ㏑(7)

∴

* the solution of the equation is 2.23 to the nearest 2 decimal places
