Answer and solve for brainlist
BartSMP [9]

Answer:

y=10x+57

Step-by-step explanation:

30pieces of candy/3 minutes=10 pieces of candy/minute (slope)

He has already eaten 57 pieces at x=0 minutes so this must be the Y-Intercept

Slope intercept form is y=mx+b

m: Slope (10)

b: y-intercept (57)

Find the length of side x in simplest radical form with a rational denominator.60°130°X
iren [92.7K]

We will solve using the law of sines as follows:

\frac{1}{\sin(30)}=\frac{X}{\sin (60)}

Now, we solve for X:

\Rightarrow X=\frac{\sin(60)}{\sin(30)}\Rightarrow X=\sqrt[]{3}

So, the length of X is sqrt(3).

Answer:

Hello your question has a disjointed equation attached to it and it is also incomplete attached below is the correct and complete question

A teacher believes that the third homework assignment is a key predictor in how well students will do on the midterm. Let x represent the third homework score and y the midterm exam score. A random sample of last terms students were selected and their grades are shown below

answer :

y-intercept = 25.9047

 slope = 2.8420

Step-by-step explanation:

Determine the slope for the regression equation and y intercept

The regression equation ( gotten using excel ; attached below is the excel sample on how the equation was gotten )

y = 25.9047 + 2.8420x

from the equation gotten above

y-intercept = 25.9047

slope = 2.8420
