Unique addresses (population size) = 1,346

Sample size = 50

Number of children - - - - - - - No of household

0 - - - - 5

1 - - - - 11

2 - - - -13

3 - - - - 10

4 - - - - 9

5 - - - - 2

Number of households with more than 3 children :

That is, households with 4 and 5 children

Total = 9 + 2 = 11 households

Therefore, proportion of households with more than 3 children :

(11 / sample size) × population size

(11 /50) × 1346 = 296.12

Approximately 296 households

Consider this sequence: -81, -54, -36, -24, … .
N76 [4]
If it is geometric then
if the terms are a,b,c,d then
b/a=c/b=d/c
so
-54/-81=-36/-54=-24/-36?
2/3=2/3=2/3

and that is the common ratio

it is geomertic and common ratio is 2/3

Hello!

To solve this you have to find the ratio between the two cylinders

Cylinder 1 height is 30
Cylinder 2 height is 20

this is a 30:20 ratio

This can be reduced to a 3:2 ratio

Now you look for one that are also equal to 3:2

3 * 7 = 21
2 * 7 = 14

The answers are 3:2 and 21:14

Hope this helps!

La Biblia dice que Matusalén vivió 979 años, mientras que Abraham vivió 175 años, escribe la fracción que indica la relación de
LenKa [72]

Answer:

A 175/979 = M

Step-by-step explanation:

Si Matusalén vivió 979 años y Abraham vivió 175 esto quiere decir que abraham vivio menos años que Matusalén.

Por lo que la fracción va a tener que ser menor que 1 ya que al multiplicarla por la edad de Matusalén nos tiene que dar la de Abraham.

Tenemos que encontrar una fraccion que multiplicada por 979 nos de 175.

979 * X = 175

Tenemos que despejar la x y encontraremos el valor de la fraccion.

979 * X = 175

X = 175/979

Nos fijamos si se puede simplificar, no se puede asique este es el resultado final.
