Answer:
7,14,21,28,35,42,49 are all dividible by 7. That are 7 Numbers. However we are looking for All the Numbers that are not a multiple of 7.
So 50-7=43.
There are 43 Numbers which are not a multiple of 7.
So 43/50=0.86
The probability is 0.86 or a 86% chance that the generator will select a Number which is not a multiple of 7.
A ) 17 because 4*2+9=8+9=17
Answer:
Miguel start to swim when Ario has traveled 4.4 m.
Step-by-step explanation:
The total lenght of the pool is 25.
Since both of them standing 3 m from one side of the pool, then, the total distance both need to cover is
m= 22 m.
Assume that the distance traveled by Ario before Miguel start to swin is
. That means, the remaining distance to Ario (to cover the total size of the pool) is
.
Then, in acoordance to the problem, the ratio between these two distances must be equal to 1/4.
That is,
.
So, we need to obtain
from this equation. We must note that
, otherwise we have a zero in the denominator.
So, we rearrange the equation,
(Multiplying both sides of equation by (
).
Then,
.
Therefore,
m.
