The number of social media post of Noami has a greater spread when compared to that of Amir.

<h3 /><h3>What is the range and intequartile range of the social media posts?</h3>

Range is the difference between the highest and lowest values of a set of observations

Range = highest value - lowest value

  • The range of Amir's social media posts = 19 - 15 = 4
  • The range of Noami's social media posts = 10 - 0 = 10

The inter quartile range is the difference between the third quartile and the first quartile of a data set.

IQR = Q3 - Q1

The IQR of Amir's social media posts: 7

The IQR of  Naomi's social media posts = 10

Answer:

Naomi"s data set has more spread since her range is 10 and her IQR is 3.

Step-by-step explanation:

Range                   IQR

12,14,15,15,16,19    16-14=2

0,2,2,4,5,10           5-2=3

19-12=7  10-0=10

The ratio of pencils to erasers is 4:1. If there are 20 pencils, how many erasers are there.
Leokris [45]

Answer: 5 Erasers

Step-by-step explanation: It's quite simple, really. You divide 20 by 4, (the number of pencils and the ratio number) and then you multiply whatever the quotient was by the ratio number for erasers.

. The volume of a box is 405 cubic units. The length is x units, the width 4 units greater than the length, and the height is 9
lukranit [14]

Answer:

length = 5

width = 9

Step-by-step explanation:

V = lwh

let 'x' = length

let '4+x' = width

9 = height

405 = 9x(4+x)

405 = 36x + 9x²

this is a quadratic equation:  9x² + 36x - 405 = 0

factor out a 9 to get:

9(x² + 4x - 45) = 0

9(x-5)(x+9) = 0

one root is 5 and the other is -9

since distance cannot be negative we use 5 as the length and 9 is the width
