What does a residual value of –0.8 mean in reference to the line of best fit?

Answers

Answer 1
Answer:

Answer:

Residual value of -0.8 means the actual point is 0.8 units below the best fit line.

Step-by-step explanation:

The difference between the observed value of the dependent variable and the predicted value is called the residual.

Mathematically,

e = y -\hat{y}

where,

e = residual,

y = observed value,

ŷ = predicted value.

When the residual is negative, the data point is below the graph or best fit line.

Residual value of -0.8 means the actual point is 0.8 units below the best fit line. It also means that the actual value is 0.8 lesser than the predicted value.
Answer 2
Answer: The given point is 0.8 units below the line of best fit

Please help. are they Parallel, perpendicular or neither

Answers

Answer:

Neither

Step-by-step explanation:

Parallel lines don't intersect

Answer:

Neither parallel or perpendicular.

Step-by-step explanation:

For AB A(-1,-4) and B(2, 11)

x1,y1 x2,y2

Gradient = (y2 - y1)/(x2 - x1)

= (11 - (-4))/(2 - (-1))

= 15/3 = 5.

For CD C(1 , 1) and D(4 , 10)

x1, y1 x2, y2

Gradient = (y2 - y1)/(x2 - x1)

= (10 - 1)/(4 - 1)

= 9/3 = 3

from the above they are neither parallel or perpendicular.

John and 2 friends are going out for pizza for lunch. They split one pizza and 3 large drinks. The pizza cost $12.50. They spend a total of $16.85. Write an equation to represent the problem. Find the cost of one large drink.

Answers

Answer:

Hm, okay.

Step-by-step explanation:

So, if the pizza cost $12.50, and the total money spent is $16.85, we must first subtract our money spent on pizza from the total amount spent.

$16.85 - $12.50 = $4.35

So, that means that John and his two friends spent $4.35 on 3 large drinks. But how do we figure out how much each individual drink cost?

We divide $4.35 by 3.

$4.35 / 3 = $1.45.

So, the amount of money spent on one large drink was $1.45.

There are 35 students in Zacks class.Out of the 35,16 prefer chocolate ice cream to vanilla (46%),while 9 prefer vanilla to chocolate (26%).What does this mean?

Answers

D) 46% of the students like chocolate ice cream better than they like vanilla ice cream. 

If you prefer something or someone over another, then that normally means you like it better than the other.

D) is the correct answer because in this description it doesn't say that any of the students dislike a type of ice cream, just that they don't prefer it.
