<span>A relationship between two variables in which one is a constant multiple of the other. The constant here is also called the constant of variation. In order to obtain this value, we manipulate the equation by isolating the variables. We do as follows:
</span><span>2x +6y = 0
y = -x/3
Therefore, the constant of variation is -1/3. Hope this answers the question. Have a nice day.</span>
Answer:
OPTION A: The company can be 95% confident, based on the method used to calculate the interval, that the true increase in mean sales for each additional 1 million persons in the marketing district is between $453,000 and $1,060,000.
Step-by-step explanation:
Note that the slope here is the increase in sales (in millions of dollars) per every 1 million increase in population. Hence, as this is a confidence interval for the slope, then
OPTION A: The company can be 95% confident, based on the method used to calculate the interval, that the true increase in mean sales for each additional 1 million persons in the marketing district is between $453,000 and $1,060,000.
Answer: x = -2
<u>Step-by-step explanation:</u>
Find 2 numbers whose product is the c-value of 4 and their sum is the b-value of 4.
x² + 4x + 4 = 0
∧
1 + 4 = 5
2 + 2 = 4 <em>this works!</em> <em>so the factors are: </em>
(x + 2)(x + 2) = 0
x + 2 = 0 and x + 2 = 0
x = -2 and x = -2 --> <em>same answer so only need to list it once</em>
From the given, there are 5 toppings available. If the pizza is to contain only two toppings, that is one of the five toppings and one of either tomato and cheese then, there will be 10 ways to prepare the pizza. Lastly, if we include the pizza with no toppings then, we have 11 types of pizza.
