Answer:
<h3>Median = 6</h3><h3>Mean = 6,1</h3><h3>Modus = 7</h3>
Step-by-step explanation:
Median (Nila tengah setelah data diurutkan)
= 4, 4, 5, 5, 6, 6, 7, 7, 7, 8, 9
= 6
Mean
= jumlah data / banyak data
= 4+4+5+5+6+6+7+7+7+8+9/11
= 68/11
= 6,1
Modus
= data yang paling banyak muncul
= 7 (muncul sebanyak 3 kali)
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
It would be great if you added some more details, but for common denominators you try to find the least common number that the 2 or more of the numbers you got have!
For example:
1/2 and 2/3 if you multiply 2 by 3 and 3 by 2, they both are 6, so you would multiply 1/2 both by 3 to make it into 3/6 and 2/3 by 2 to make it into 4/6!
(2/3) / (1/6) ...when dividing fractions, flip what u r dividing by, then multiply
2/3 * 6/1 = 12/3 = 4 scoops
