Answer:
Which statement best explains how enzymes speed up a chemical reaction?
Enzymes add heat to a chemical reaction.
Enzymes lower the activation energy of a chemical reaction.
Enzymes remove heat from a chemical reaction.
Enzymes are not changed as a result of a chemical reaction.
Step-by-step explanation:
1a) 25/100 so 1/4
1b) 7 billion times .25 is 1,750,000,000
2) 17 divided by 8 is 2.125 times more
Probability =
(number of ways to succeed) / (total possible outcomes) .
There are 6 total possible outcomes of rolling one honest die.
Only one of them is a ' 4 '.
-- So the probability of rolling a '4' on the first roll is 1/6 .
-- The probability of rolling a '4' on the second roll is 1/6 .
-- The probability of BOTH events is
(1/6) x (1/6) = 1/36 = (2 and 7/9) percent .
