Answer:  1) Product property of logarithm,

2) Subtraction property of logarithm

3) Equality property of logarithm

Step-by-step explanation:

By the Product property of logarithm,

log a + log b = log(a.b)

And, By the Subtraction property of logarithm

log a - log b = log(a/b)

Also, by the equality property of logarithm,

log(a) = log(b) ⇒ a = b

Given expression,

log_2(5)+log_2(x+2)-log_2(x+1)=log_2(7)                                                                

\implies log_2(5(x+2))-log_2(x+1))=log_2(7)  (Product property of logarithm)

\implies log_2(\frac{5(x+2)}{2(x+1)})=log_2(7)  (Subtraction property of logarithm)

\implies \frac{5(x+2)}{2(x+1)}=7   ( Equality property of logarithm )

\implies 5(x+2)=7(x+1)    ( Multiplicative property of equality )

\implies 5x+10=7x+7  ( Distributive property of equality )

\implies 3=2x    (subtraction property of equality )

x=\frac{3}{2}       (division property of equality )

1. Sam rolls a fair dice and flips a fair
kicyunya [14]

Answer:

Mark brainliest pls

Step-by-step explanation:

People have given you correct answers but not explained why, perhaps because it seems so obvious.

One of Bayes laws of probability says that if two events e1 and e2 are independent (unrelated), then the probability of both happening together is the product of their individual probabilities.

The die and the coin are independent events. Each is a 50% chance (odd number on a die, heads on a coin). Thus the probability of both happening together is 50% * 50% = 25%.
