The equation for the line of best fit, the good approximation for x when f(x) = 30 is 20.

Given that

The equation for the line of best fit is f(x) = 1.8x − 5.4 for the set of values in the table.

A 2-column table with 7 rows.

The first column is labeled x with entries 4, 5, 6, 6, 8, 9, 10.

The second column is labeled f(x) with entries 5, 2, 5, 6, 8, 7, 18.

We have to determine

Using the equation for the line of best fit, what is a good approximation for x when f(x) = 30?

According to the question

The quadratic regression equation can be expressed as;

\rm f(x) = 1.8x - 5.4

Then,

The approximation for x when f(x) = 30 is,

\rm f(x) = 1.8x - 5.4\\\\\rm 30= 1.8x - 5.4 \\\\ 1.8x= 30+5.4\\\\1.8x=35.4\\\\x = \dfrac{35.4}{1.4}\\\\x=19.67\\\\x=20 \ approx

Hence, the equation for the line of best fit, the good approximation for x when f(x) = 30 is 20.

RideAnS [48]

Answer:

2 hours=120 mins

120-(45+25)

120-(70)

50

Ron has enough time to finish his homework and walk the dog before his lesson. Ron should overestimate the total time needed. Since Ron has 50 minutes to spare he could add 25 to home work time and another 25 to walking his dog. he still ha time to do both.

The options for the first blank are 45, 240, 270, and 315
Schach [20]

Answer:

The solutions are <u>270°</u> and <u>450°</u>.

Step-by-step explanation:

Given:

cos\frac{x}{2} =\frac{\sqrt{2} }{2}.

So, the second and third quadrant angle to be calculated.

cos\frac{x}{2}=135

=x=270°.

And, cos\frac{x}{2}=225

=x=450°

Therefore, the solutions are <u>270°</u> and <u>450°</u>.
