Step-by-step explanation:
Here's a graph as well.
Mean is when you add up all the numbers, then divide by how many numbers there are
<span>39 + 43 + 46 + 86 + 22 + 39 + 75 = 340
340 </span>÷ 7 (because there are 7 numbers) = 48.57
Area rectangle: L * W
5 * 9
Area triangle: (1/2) * b * h
(1/2) * 3 * 4
Rectangle = 45
Triangle = 6
45 + 6 = 51 cm^2
Answer:
y = 5x
Step-by-step explanation:
The equation for direct variation is y = kx, where k is the factor of variation. So we know that y and x must fit into this formula.
They've given us a y and x value to solve for k.
y = kx
15 = 3k
15/3 = k
<u>k = 5</u>
Plug k back into our equation.
y = 5x
Answer:
The independent variable is the variable the experimenter changes or controls and is assumed to have a direct effect on the dependent variable. In other words, the dependent variable is the one you measure and the independent is the one you change in an experiment.
