Write a story about elevation that this expression could represent: 56 + (-56)

Mathematics

Ostrovityanka [42]2 years ago
7 0

The correct statement that represents the expression is:

  • An object moves towards the east (positive direction )at a distance of 56m and west (negative direction) at the same distance, the total displacement of the object is 0m

Given the expression 56 + (-56).

  • We can see that this is an inverse rule where a value and its negative are added together.

Let us assume the values are distance covered by an object.

The correct statement that represents the expression is:

  • An object moves towards the east (positive direction )at a distance of 56m and west (negative direction) at the same distance, the total displacement of the object is 0m

This show that  56 + (-56) = 56 - 56 = 0

Let sugar be the explanatory variable and calories be the response variable; which scenario best describes ŷ = 57 + 2.5x?
algol13

Answer: Choice E)

The amount of calories in fruit juice increases by 2.5 for every one gram of sugar. The calorie amount estimated by this model is 57 if there are zero grams of sugar.

=============================================================

Explanation:

x = amount of sugar (in grams)

y = number of calories in the juice

ŷ = estimate of y, so its the estimate of calories in the juice

The regression equation rearranges to ŷ = 2.5x + 57

This is in the form y = mx+b where m = 2.5 is the slope and b = 57 is the y intercept.

The slope tells us what the rate of change is. Specifically, it tells us how much the amount of calories (y) is going up each time the amount of sugar (x) goes up. Each time x goes up by 1, y goes up by 2.5

The y intercept 57 is the starting or initial amount of calories. If you have 0 grams of sugar, the lowest amount of sugar possible, then you start off with 57 calories. We can see this by plugging x = 0 into ŷ = 2.5x + 57 (you should get ŷ = 57). Visually, the y intercept is where the line crosses the y axis.

All of these facts point to choice E as the final answer.
