Answer:
y = -2/3x
Step-by-step explanation:
A perpendicular line is the negative reverse of the slope of the other line. I'm not sure about the options you have there but hopefully this helps you get your answer.
Equation:
x/3 = x/8 + 2/3
---
Multiply thru by 24 to get:
8x = 3x + 16
5x = 16
x = 3 1/5

Answer:
Step-by-step explanation:
For a multiple regression model with 3 independent variables,
Y = A0 + A1X1 + A2X2 + A3X3
The hypotheses for the global test of a multiple regression model are:
Null hypothesis H0: there is no relationship between the slopes - A1, A2, A3 - and the outcome. A1, A2, A3 = 0; R^2 = 0
Alternative hypothesis H1: there is a relationship between at least one of the slopes and the outcome. One of A1, A2, A3 is not equal to zero. R^2 is not equal to zero.
Answer:
For this question, you need you use the unitary method or proportion. If you apply these ideas to it. You should be able to do this question. Here's my working:
Step-by-step explanation:
25ounces = $3.49
**You need to find what's the price of one ounce**
So assume it like this:
1 ounce = $X
To solve for X, you figure out how did 25 became 1. In this case, it has been divided by 25. So you do the same thing on the other side: Which is $3.49 ÷25 = 0.1396 (Price per ounce for choice A)
Choice B workings:
You apply the same method, so it's 4.79 ÷ 45 = 0.1064444444444 (Price per ounce for Choice B)
So in conclusion, <em>Choice B is cheaper. </em>
