Molly played an online game three times. Her scores were 5.5, -3.6, and 12.8. What was her average score for three games?

Ivahew [28]

In order to find the solution you must calculate the mean, or the average by adding the numbers together and dividing by how many numbers there are.

5.5 + -3.6 + 12.8 = 14.7

14.7 ÷ 3 = 4.9

4.9 is Molly's average score.

Hope this helps! <3

4. Han's younger sister is riding her tricycle in a straight line. After 3 s, her speed is 0.5 m/s. After 5 s, her speed is 1.5

Answer:

Han's younger sister accelerated at a rate of 0.5 meters per square second during that time.

Step-by-step explanation:

Let suppose that Han's younger sister accelerates at constant rate, then, acceleration ( $a$ ), measured in meters per square second, can be calculated by the following equation:

$a = \frac{v_{f}-v_{o}}{t_{f}-t_{o}}$

Where:

$t_{o}$ , $t_{f}$ - Initial and final times, measured in seconds.

$v_{o}$ , $v_{f}$ - Initial and final speeds, measured in meters per second.

If we know that $t_{o} = 3\,s$ , $t_{f} = 5\,s$ , $v_{o} = 0.5\,\frac{m}{s}$ and $v_{f} = 1.5\,\frac{m}{s}$ , the acceleration of the younger sister is:
