Since the regression equation is:  y = 30 8x. if SSE= 960,  the correlation coefficient is 0.661.

<h3>What is the regression equation about?</h3>

A regression equation is known to be a tool that is often used in statistics to examine if any relationship exists or not between a given sets of data.

Note that:

SSR=SST-SSE

So the first step is to calculate the R² which is seen as the coefficient of equation. This will be:

= 1 - SSE/SS Total

= 1 - 900/1600

= 1 - 0.5625

= 0.4375

Then, the correlation coefficient will be:

= ✓0.4375

= 0.661

Therefore, Since the regression equation is:  y = 30 8x. if sse = 960,  the correlation coefficient is 0.661.

Rolling a Red and Yellow Dice
grandymaker [24]

Answer:

Option C 5/12 is correct option

Step-by-step explanation:

We have to find the probability that shows yellow dice has a larger value than the red dice.

Probability= total no of favorable outcomes / total no of outcomes

in our case, considering the data set, we have to find those pair where value of yellow die is greater than the red die. Where (1,2) represents 1 on the red die and 2 on the yellow die

(1,2) (1,3) (1,4) (1,5) (1,6)

     (2,3) (2,4) (2,5) (2,6)

              (3,4) (3,5) (3,6)

                       (4,5) (4,6)

                                (5,6)

These are the possibilities where yellow die has greater value than red die.

total no of favorable outcomes = 15

total no of outcomes = 36

probability that yellow die has greater value than red die = 15 / 36

                                                                                                = 5/ 12

Option C 5/12 is correct option

Write this number in standard form. 300+80+0.9+0.06+0.001
Lina20 [59]

Hey there! I'm happy to help!

First, let's add the hundreds and the tens.

300+80=380

We see that there is nothing in the ones place, so we keep our ones place 0 and we move onto adding the tenths.

380+0.9=380.9

We add the hundredths.

380.9+0.06=380.96

And finally, we add the thousandths.

380.96+0.001=380.961

Therefore, this number in standard form is 380.961.

Have a wonderful day! :D
