Im not sure but i think it is 15 - x
Let X be the original price.
Do a 40% increase we get the price: X+0.4X=1.4X
Doing a 25% off we get the new price:
(1.4X)-0.25(1.4X)=1.05X
=X+0.05X.
The new prices are 5% increase from the original price.
Providing a short wikipedia definition here: "In mathematics, a rational number is any number that can be expressed as the quotient or fraction"
So any fraction would work for this question I believe?
Answer:
There is sufficient evidence at the 0.05 level
Null hypothesis ; H0 : p = 0.47
Alternative hypothesis : H1 : p ≠ 0.47
Step-by-step explanation:
percentage favoring construction of adjoining community = 47%
level = 0.05
To determine if the 0.05 confidence level is enough to support the major's claim we have to state the Null and alternative hypothesis
Null hypothesis ; H0 : p = 0.47
Alternative hypothesis : H1 : p ≠ 0.47
