A diagonal of a cube measures StartRoot 294 EndRoot cm. The diagonal of a face measures 14 cm. What is the length of an edge of

hram777 [196]

The side of the edge of the cube is 9. 9cm

<h3>How to determine the length</h3>

Given that the diagonal of a cube measures the square root of 294cm and the diagonal of a face measures 14cm

To find the edge of the face, we know that the face of the cube is a square

Formula for diagonal of a square = $\sqrt{2a}$

Where is the side of the square

We then have,

$\sqrt{2a} = 14$

Make 'a' the subject

a = $\frac{14}{\sqrt{2} }$

Simplify the surd

a = $\frac{14}{\sqrt{2} }$ × $\frac{14}{\sqrt{2} }$

a = $\frac{14\sqrt{2} }{2}$

a = $7\sqrt{2}$

a = 9. 9cm

Therefore, the side of the edge of the cube is 9. 9cm

Find the (a) mean, (b) median, (c) mode, and (d) midrange for the data and then (e) answer the given question.

inn [45]

Answer:

Step-by-step explanation:

(a) MEAN = £fx/ fx (The sum of the all jerseys number/ number of jerseys)

= 680/11

= 61.8

(b) MEDIAN = The middle number when all the items are arranged either in ascending order or descending order

= 6, 14, 50, 51, 54, 68, 77, 78, 89, 94, 99

= 68

(Strike out the numbers, the middle number left is the median)

(c) MODE= (Mode implies the number with the highest frequency)

From those items, THERE IS NO MODE.

All the items (numbers) appeared once

(d) MID-RANGE:

This is the sum of the least valued number and the greatest valued number and dividee by two

Mid-range = (99 + 6) / 2

= 105/2

= 52.5

(e). The results tells us that:

The mean and median give two different interpretations of the average (or typical) jersey number, while the midrange shows the spread of possible jersey numbers

Also, pls note that the median implies the measure of the middle of the sets of jerseys number. And the mean tells us the distribution of the sets of jerseys number.

Hope this helped!
