Answer:
C 8.0
Step-by-step explanation:
Assuming the linear model y=mx+b where m is the slope and b the intercept.
For this case the slope with the following formula:
Where:
After the calculations we see that m=3 and b=2 from the info given by the linear model.
For this case we have the equation obtained by least squares given by:
Where 2 represent the intercept and 3 the slope. We are interested on the best predicted value of y when x=2.
If we see our linear model we have the equation in terms of y and x. So we can replace directly the value of x=2 into the equation and see what we got:
Answer:
<h2>Option 2 is the right answer.</h2>Step-by-step explanation:
We need to check if the two characteristics, <u>having blue eyes and being deaf are independent of each other or not</u>.
The above two characteristics will be independent if
Now, the probability of having blue eyes is .
The probability that the Dalmatians will be deaf is .
The probability of being deaf with blue eyes is .
Since, 38 is not equals to 42, the two characteristics are not independent.
Radius / diameter as a length cannot be negative, that's why '-16' is wrong.
