Translate and solve: seventy-eight times n is at least 312.

1 answer:

7 0

It translates to $78n \ge 312$ which solves to $n \ge 4$ after dividing both sides by 78. This means n is equal to 4 or it can be larger than 4.

The plot shown below describes the relationship between the average income in a city and the average rent for a 111-bedroom apar

Nikitich [7]

Answer:

The average change in rent can be determined by substituting the value of X as 5000 in the regression equation.

Step-by-step explanation:

A simple linear regression line is used to predict the value of the dependent variable from the independent variable.

The general form is:

$Y=\alpha +\beta X$

Dependent variables are those variables that are under study, i.e. they are being observed for any changes when the other variables in the model are changed.

The dependent variables are also known as response variables.

In this case the dependent variable is the average change in rent for a 1-bedroom apartment.

Independent variables are the variables that are being altered to see a proportionate change in the dependent variable. In a regression model there can be one or more than one independent variables.

The independent variables are also known as the predictor variables.

In this case the independent variable is the average income in a city.

So, for an increase of $5,000 in incomes the average change in rent can be determined by substituting the value of X as 5000 in the regression equation.

Which graph has the same end behavior as the graph of f(x) = –3x^3 – x^2 + 1?

ololo11 [35]

To find out end behavior, we always look at the largest exponent (3 in this case) and the sign of the term with the largest exponent (negative in this case). We can rule out the first two choices because since it is a cubic graph (exponent of 3) the graph will be pointing in opposite directions. Then, the negative tells us that as the x values approache infinity, the y values will approach negative infinity. So the correct answer is the last choice.

Hope this helps

A trampoline salesman makes $25,000 annually plus 6% commission on his total sales. If he sold $40,000 worth of trampolines this

Katarina [22]

Multiply sales by 6%

40,000 x 0.06 = 2,400

Add that to his base pay:

2400 + 25000 = $27,400 total pay.

Jamie made the tree diagram below to show the different choices he has for ordering a pizza for lunch. According to the tree dia

USPshnik [31]

Sizes = Small, Medium and Large, so they has 3 choices for size.

Crust = Thin or thick for each size, so they have 2 choices for crust.

Topping = Tomato or meatball for each one, so they have 2 choices for toppings.

The answer would be:

Three choices for size, two choices for crust, and two choices for topping
