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):
Answer:
3964 in³
Step-by-step explanation:
volume of sphere: V = 4/3 πr³
v₁ = 4/3 x 3.14 x 7³ = 1436
volume of prism: v = Bh B = 15 x 18 = 270 h = 20
v₂ = 270 x 20 = 5400
v₂ - v₁ = 5400 - 1436 = 3964 in³
Answer:
10/14
Step-by-step explanation:
there is 14 cards in total and theres 7 yellow cards pluss adding the 3 blue cards making 10/14
sorry if i get it wrong
Answer:
a)78
b)82.95
Step-by-step explanation:
To get the amount something is marked up you just need to multiply it by
1+0.(the%)
so in this case you multiply 60 by 1.30 to get 78
To get a discount you just have to do the same but without the +1
so 88*0.15
should get you the discount amount (13.2)
which you subtract from the original number (88-13.2 = 74.8)
now to get sales tax you would multiply the 79 by 0.05 which is 3.95
and add that to the total of 78.75 since sales tax applies AFTER coupons
Answer:
x+16
Step-by-step explanation:
For this one the negative signs become positive because, if you multiply a negative number*a negative number it becomes positive. That is a rule.
