Factorice 10=5×2. Vuelva a escribir la raíz cuadrada del producto 5×2 como el producto de las raíces cuadradas 52.
552+52
Multiplica 5 y 5 para obtener 5.
52+52
Para multiplicar 5 y 2, multiplique los números bajo la raíz cuadrada.
52+10
Answer:
1/2 and 13/18 respectively
Step-by-step explanation:
even-number results:
2, 4 6 ,8, 10 and 12
the combinations of each result are respectively
1+3+5+5+3+1 = 18
The total number of combinations on a roll pair is 36
then the probability of obtaining an even result is:
p = 18/36 = 1/2 or 0.5
so that the result is less than nine, we eliminate the combinations of results 9, 10, 11 and 12:
4 + 3 + 2 + 1 = 10
36 -10 = 26
the probability of obtaining a result less than nine is:
p = 26/36 = 13/18 or 0.72

Sorry :( if it is wrong
If we use a number line
Eg below
12 11 10 9 8 7 6 5 4 3 2 1 0 -1 -2 -3 -4 -5 -6 -7 -8 -9 -10 -11 -12
Visual of what it would look like from greatest to least
