Answer:

To find the mean , median and mode of the students.

Step-by-step explanation:

The students choose from the three definitions of average to find the mean, median or mode of the students’ height in the school.

Students develop a strategy, collect and record data, and analyse data to answer this question.

The key concepts are

Consolidating the terms mean, median and mode.

The students should find the median of the height for the school if they have collected the median result of each grade.

The exponential functions change is represented by decay and the percentage rate of decrease is 1.00619%.

Step-by-step explanation:

Step 1:

To determine if the function represents growth or decay, we substitute values to x.

If the values increase with an increase of x, it represents growth.

If the values decrease with an increase of x, it represents decay.

Step 2:

If $x= 10,$ $y = 1,300 (\frac{1}{2})^{\frac{10}{69} } = 1,300 (0.9044) = 1,175.72.$

If $x=11,$ $y = 1,300 (\frac{1}{2})^{\frac{11}{69} } = 1,300 (0.8953) = 1,163.89.$

So as x increases the value of y decreases, so it represents decay.

Step 3:

The percentage rate of change is determined by dividing the difference of two consecutive values by the first value.

The percentage rate of change $= \frac{y(x=11) - y(x=10)}{y(x=10)}.$

Substituting the values, we get

The percentage rate of change $=\frac{1,175.72-1,163.89}{1,175.72}(100) = 1.00619\%$ .

As the values of y decrease with an increase in x, it is the percent decrease per unit.

Answer:

y=8x-11

Step-by-step explanation:

Use Point-Slope Form

Which is y-y1=m(x-x1)

If we fit the coordinates and slope in the equation, it is y-5=8(x-2)

=y-5=8x-16

=y=8x-16+5

=y=8x-11

And so the answer of the problem is y=8x-11
