It would cost $20.12 because if you multiply $4.47 by 4 pounds you would get 17.88. Then, you would divide $4.47 by 2 and get 2.235 but round that number up to $2.24. After adding $17.88 and $2.24 together, you recieve a total of $20.12
Hope this helps you!
Answer:
Brett is working in the chemistry lab trying to determine if he can predict the volume of three different gases (nitrogen, oxygen, and carbon dioxide) based upon the pressure applied to them. He kept all other characteristics of the gases constant. Brett performed the following analysis:
9-60 Graph
9-60 Residuals
Discuss the association, including slope and -squared.
Hint (a):
What is the residual with the greatest magnitude and what point does it belong to?
Hint (b):
Answer (b):
Using the LSRL model, estimate the volume of a gas at , and atmospheres. Use an appropriate precision.
Hint (c):
Answer (c):
How well would this linear model work in predicting more extreme pressures? Support your answer.
Hint (d):
The correct answer is 45ft(along the ground)
Explanation:
It is making the right angled triangle as one half is 28 feet tall(vertically straight); the other half which fell over some distance is the hypotenuse. To find its length:
Hypotenuse = 81 - 28 = 53
Now that we have hypotenuse and the vertical length (perpendicular), we can find the base( along the ground) using Pythagoras theorem:
c^2 = a^2 + b^2
c = hypotenuse
a = perpendicular
b = base
53^2 = 28^2 + b^2
b = 45ft (along the ground)
Correct answer is right down, increase gives sign +, drop or decrease gives sign -
Start by finding the slope of the line by doing m(slope)=y2-y1 over x2-x1 using the pairs and then plug in the y and x of one of the points into the equation y=mx+b (y in the y and x in the x spot) and solve for b. Then plug the slope (can be a fraction shouldn’t be decimal) and y-intercept (b) back in the equation of a line above and you have your answer!
