Helppp pls for the 2 people willing to help .
Shtirlitz [24]

Step-by-step explanation: I honestly am too lazy to solve but I will tell you what to do. For number 1-5 you need the amount (a) divided by the Tax/Tip/%off/Discount(d). Whatever that number is (t), you subtract that from a to get the total cost which is (c) So in other words - a-d=t a-t=c UWU

Then onto the next ones. Number 6: First you do 11/2800. Thats the 11%. Next you get 67,530 divide that by that last number you got. Then multiply that by 2800. Then there is your answer

Okay so next one Number 7: Same thing as the other one actually -v-

Next answer mate! Number 8: 3400 x4 + (3400/3.5) x 4= ???? You tell me that ;)

We almost doneeee Number 9: 20460 x 5 + (20460/5.5) x 5= ____ Hhehehehe last one mateyyyy

We actually at the last one. Its been fun helping you! :) Number 10: 35000/7 then whatever that is times 5. I enjoyed going back in my little kid brain tohelp you :)

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.
