So if the standard deviation of the data set is 1.69, a z-score of 1 would mean that the data point is 1.69 units above the mean. In Sal's example, the z-score of the data point is -0.59, meaning the point is approximately 0.59 standard deviations, or 1 unit, below the ... Algebra 1 16 units · 184 skills.

At this point in the video, the problem is: 10 x 4 / 2 - 5 x 6. Sal solves left to right: 40 / 2 - 5 x 6 = 20 - 30 = -10. But if I don't do it in the same order I get the same answer: 10 x 2 - 5 x 6 = 20 - 30 = -10.

To solve the equation (3/4)x + 2 = (3/8)x - 4, we first eliminate fractions by multiplying both sides by the least common multiple of the denominators. Then, we add or subtract terms from both sides of the equation to group the x-terms on one side and the constants on the other. Finally, we solve and check as normal.Course: 5th grade > Unit 5.
