The mean sat verbal score is 486, with a standard deviation of 95. use the empirical rule to determine what percent of the score

The <span>root<span> of a numeral x represents another number that, when multiplied by itself for a specific amount of times, results in x. For instance, the square <span>root<span> of 9 is 3, given that 3 x 3 equals 9. The square <span>root<span> is the term commonly used for the second <span>root<span>. Meanwhile, the term for the third <span>root<span> is known as the cube <span>root<span>. Refer to <span>Root<span> (of a number). because then/</span> </span></span></span></span></span></span></span></span></span></span></span></span></span>

Answer:

Below is the answer

Step-by-step explanation:

The linear model illustrates the height, f(x), of a water balloon thrown from a building over time, x, in seconds: It shows ordered pairs at 0, 60 and 2, 75 and 4, 75 and 6, 40 and 8, 20 and 10, 0 and 12, 0 and 14, 0. The x-axis indicates Time in seconds, while the y-axis represents Height in feet. Part A: At what interval(s) is the water balloon's height increasing? (2 points) Part B: At what interval(s) does the water balloon's height remain constant? (2 points) Part C: At what interval(s) is the decrease in the water balloon's height most rapid? Use complete sentences to explain. (3 points) Part D: Utilizing real-world conditions, predict the water balloon's height at 16 seconds.

Answer:

Part A: The water balloon's height increases between 0 and 2 seconds, from 60 feet to 75 feet.

Part B: The balloon’s height remains at 75 feet from 2 to 4 seconds. At 10 seconds, it is at 0 feet.

Part C: The most rapid decrease in height occurs from 4 to 6 seconds, where it falls from 75 feet to 40 feet (about -17.5 ft/s).

From 6 to 8 seconds, it decreases from 40 feet to 20 feet (around -10 ft/s).

Between 8 and 10 seconds, it drops from 20 feet to 0 feet (also about -10 ft/s).

Therefore, the steepest decline is between 4 and 6 seconds.

Part D: Based on real-world constraints, at 16 seconds, the balloon will still be on the ground, so its height is 0 feet.

Let's pick arbitrary numbers: suppose 1 unit of petroleum costs 100 bitcoins (because why not).

A 10% price rise makes it 100*1.1 = 110 bitcoins per unit.

If consumption falls by 10%, he now buys 0.9 units, so his expense is 110 * 0.9 = 99 bitcoins. Previously it was 100, so now it's 99. Therefore his petroleum spending has decreased by 1%
