This exercise practices finding a new equilibrium price and quantity when supply changes, demand changes, or both supply and demand are changing simultaneously.`
Dividing whole numbers to get a decimal quotient like 15÷6=2.5
Make conclusions in a t test for slope based on the p-value and significance level, or from a confidence interval.
Practice solving word problems by adding and subtracting fractions. The fractions used in these problems have like (common) denominators.
Do you understand how two-way tables really work? Here's your chance to practice. Go get 'em! You got this!
See how we can use the axes on the coordinate plane to represent quantities.
Record measurements on line plots (also called dot plots) using rulers and frequency tables.
Let's solve some problems where we identify which phasor diagrams correspond to which circuits and vice-versa.
Let's solve some problems to better understand how phasors represent trigonometric equations with different phases. This brings us a step closer to using phasors to analyze physical quantities that vary sinusoidally.
Overview of plants, alternation of generations

Check your understanding of gravitational forces in this set of free practice questions aligned to NGSS standards.
Given two figures on the coordinate plane, find the formal definition of the translation that takes one figure to another.
Given a figure and a definition of a dilation, select or manually draw the image.
Solve real-world problems that can be modeled by right triangles, using the Pythagorean Theorem!
Given the side lengths of a right triangle, find the sine, cosine, or tangent of one of the acute angles.
Identify which properties of shapes remain the same after a rigid transformation (reflection, rotation, translation) has been applied.
Use your knowledge about the effects of rigid transformations to solve problems about figures and their images under transformations.
Given a figure and its image under a dilation, determine the dilation's center point.
This exercise tests the understanding of the general principles of the classification of fungi.
