Answer:

12 cm

Step-by-step explanation:

width = x

length = x + 5

perimeter = 38cm

perimeter = length + width + length + width

x + 5 + x + x + 5 + x = 38

4x + 10 = 38

4x = 28

x = 7

length = x + 5 = 7 + 5 = 12

Answer:

Length: 12 cm

Step-by-step explanation:

2x + 2(x+5) = 38cm

2x + 2x + 10 = 38

4x = 38 - 10

x = 28/4

x = 7

Length: 7+5=12cm

Tresset [83]

Answer:

$\begin{array}{ccc}{Midpoint} & {Class} & {Frequency} & {64} & {63-65} & {1} & {67} & {66-68} & {11} & {70} & {69-71} & {8} &{73} & {72-74} & {7} & {76} & {75-77} & {3} & {79} & {78-80} & {1}\ \end{array}$

Using the frequency distribution, I found the mean height to be 70.2903 with a standard deviation of 3.5795

Step-by-step explanation:

Given

See attachment for class

Solving (a): Fill the midpoint of each class.

Midpoint (M) is calculated as:

$M = \frac{1}{2}(Lower + Upper)$

Where

$Lower \to$ Lower class interval

$Upper \to$ Upper class interval

So, we have:

Class 63-65:

$M = \frac{1}{2}(63 + 65) = 64$

Class 66 - 68:

$M = \frac{1}{2}(66 + 68) = 67$

When the computation is completed, the frequency distribution will be:

Solving (b): Mean and standard deviation using 1-VarStats

Using 1-VarStats, the solution is:

$\bar x = 70.2903$

$\sigma = 3.5795$

See attachment for result of 1-VarStats
