Answer:
b.7
Step-by-step explanation:
you take the three and substitute that in for x. 2(3) + 1
2(3)=6 then add 1
Answer:
For this case the value of r = -0.66
Now we can calculate the determination coeffcient:

And then we can conclude that 43.56% of the variation in y can be explained by the explanatory variable
And then 100-43.56 = 56.44 % of the variation in y that cannot be explained by the explanatory variable
Step-by-step explanation:
For this case we need to calculate the slope with the following formula:
Where:
And we can find the intercept using this:
And the model obtained for this case is:

The correlation coefficient is a "statistical measure that calculates the strength of the relationship between the relative movements of two variables". It's denoted by r and its always between -1 and 1.
And in order to calculate the correlation coefficient we can use this formula:
For this case the value of r = -0.66
Now we can calculate the determination coeffcient:

And then we can conclude that 43.56% of the variation in y can be explained by the explanatory variable
And then 100-43.56 = 56.44 % of the variation in y that cannot be explained by the explanatory variable
Answer:
108 inches
Step-by-step explanation:
one yard = 36 inches
multiply 36 by 3
Answer:
-76
Step-by-step explanation:
A positive digit multiplied by a negative digit will result as a negative digit.
So,
6 · -8 = -48
Now if there is a problem where a number is added by a negative digit number, you turn the "plus" sign into a "negative" sign.
So,
- 48 + (- 28)
-48 - 28
If you subtract a negative by a negative, the answer will be negative BUT you have to ADD those two negative digits together and put the negative sign after.
- 48 - 28 = -76
Answer:
See both answers in the explanation
Step-by-step explanation:
Given data
Cost of dinner= $32
TIp=18%
Let us find the amount of the tip
=18/100*32
=0.18*32
=$5.76
Hence the total amount paid is
=5.76+32
=$37.76
The Tip is
=$5.76
