4. Which statement is true about both laws and theories? a) Only laws have been tested while theories are an educated guess

b) Widely accepted by the majority of scientists within a given field of study

c) Do not change over time or when new evidence is found

d) A hypothesis can become a theory, then a theory can become a law

d)

Step-by-step explanation:

While a) is possible, theories are usually backed up by some evidence making it, in that case not just an educated guess. An hypothesis on the other hand is an educated guess.

b) is not specific to what it is talking to but if it's about laws, then yes it's right but theories are not always widely accepted. In fact it isn't likely that they would be accepted at all since it's not a fact or law.

c) is just wrong because theories can become law if enough evidence is found. Which is a change that can happen over time so that is just incorrect

d) is correct because enough evidence can make an hypothesis into a theory because it's backed by some evidence(although it make have some holes in it) and if there is enough concrete evidence, a theory can become a law

75 tickets have been sold so far.

step-by-step explanation:

in this question it is clearly mentioned that 45 children's tickets have been sold and this number is 60% of the total tickets sold.

now let's assume the total number of tickets sold be x.

then 60% of x = 45

⇒

⇒ x(.6) = 45

by dividing with .6 on both the sides of the equation

⇒ x = 75

therefore 75 tickets have been sold so far.
