Answer:
16.2 kilograms
Step-by-step explanation:
30 300-gram cans = 9000 grams of soup
18 400-gram cans = 7200 grams of vegetables
9000 + 7200 = 16200 grams
1000 grams = 1 kilogram
16200 / 1000 = 16.2 kilograms
Answer:
Explanatory variable = Effect of music
Response variable = Memory response
Step-by-step explanation:
An explanatory variable, also known as independent variable, is a variable that can be manipulated so as to analyse their effect on another variable. It is used to predict or explain differences in another variable.
Response variable is a variable whose variation depends on other variable. It is also called a dependent variable.
In this analogy, since the effect of music on memory is what is to be known, music is the explanatory variable while memory is a response variable.
Part A: Greg mixed 2 cups of yellow paint with one cup of blue paint to make green paint.
Part B: He needs to add half a cup of blue paint to one cup of yellow paint because there needs to be one cup of blue, for every two cups of yellow.
Part C: The unit price for one cup of yellow paint is $9.
For the number 7, begin by solving for k.
Remember your discriminant rules:
k is greater than 0, there are 2 real solutions
k is equal to 0, there is one real solution
k is less than 0, there are no real solutions
On number 8, solve for a, and then figure out the number of solutions using the rules above.
Hope this helps!
