A particular chemistry book costs $6 less than a particular physics book, while two such chemistry books and three such physics
1 answer:
Answer:
Step-by-step explanation:
Let's say the Physics book costs $x
The Chemistry book will cost $x - $6
Two such Chemistry books will cost;
2($x - $6) = $(2x - 12)
Three such Physics books cost $3x
$(2x - 12) + $3x = $123
$5x - $12 = $123
$5x = $111
x = $22
So the Physics book costs; $22
and the Chemistry book costs $22 - 6 = $16

Step-by-step explanation:
From the question we are told that
Two fair dice, one green and one red were rolled
Generally the outcomes on the dice independent because the outcome on the first dice is not affected by the second die
Generally the probability of getting a 1 on a dice rolled is
the probability of getting a 5 on a dice rolled is
Generally the probability of P(1 on green die and 5 on red die) is mathematically represented as
Generally the probability of P(5 on green die and 1 on red die) is mathematically represented as
Generally the probability of P((1 on green die and 5 on red die) or (5 on green die and 1 on red die)) is mathematically represented as
The slope of the line is 4/10
