Answer:

○ B $\displaystyle Associative\:Property\:of\:Multiplication$

Step-by-step explanation:

This may look like the <em>Commutative</em><em> </em><em>Property</em><em> </em><em>of</em><em> </em><em>Multiplication</em><em> </em>because of the order they are put in, however, since we have GROUPING SYMBOLS, this would be known as the Associative Property of Multiplication.

Answer:

30

Step-by-step explanation:

Work backwards:

6 is 3/5 of a number, and that number is 10
10 is 1/3 of a number, and that number is 30

Check your work:

2/3 of 30=20 toy to Sarah
30-20=10 toys left
2/5 of 10=4 toys to Ryan
10-4=6 toys left

Answer:

a

$P(r n L) = 0.12$

b

$P(L) = 0.225$

c

$P(\= r | L) = 0.4667$

Step-by-step explanation:

The chance that it will rain is $P(r ) = 0.30$

The chance that it does not rain is $P(\= r ) = 1 - P(r )$

$P(\= r ) = 1 -0.30$

$P(\= r ) = 0.70$

The probability that the bus run late if it rains is $P(L | r) = 0.4$

The probability that the bus run late if it does not rain is $P(L | \= r) = 0.15$

Generally the probability that it will rain and the bus will be late is mathematically represented as

$P(r n L) = P(L | r) * P(r)$

=> $P(r n L) = 0.4 * 0.30$

=> $P(r n L) = 0.12$

Generally the probability that the bus will be late is mathematically represented as

$P(L) = P(r) * P(L|r) + P(L | \= r) * P(\= r)$

=> $P(L) = 0.30 * 0.4 +0.15*0.70$

=> $P(L) = 0.225$

Generally given that the bus ran late, the probability that the bus it was not raining is mathematically represented as

$P(\= r | L) = 1- P(r | L )$

Here $P(r | L ) = \frac{P(r n L)}{P(L)}$

=> $P(r | L ) = \frac{0.12}{0.225}$

=> $P(r | L ) = 0.533$

So

$P(\= r | L) = 1- 0.533$

=> $P(\= r | L) = 0.467$
