The percentage of published studies that supported the tested hypothesis has changed from 70 to 85% over the past 25 years.
Hypothesis testing:
A hypothesis testing means investigates a proposed mathematical model to determine whether there is sufficient evidence from a sample of data to reject the defined null hypothesis.
Given,
The percentage of published studies that supported the tested hypothesis has changed from _____ to _____ over the past 25 years.
Here we need to find the change in the percentage for the past 25 years.
Based on the details, the percentage of published studies that supported the tested hypothesis has changed from 70 to 85% over the past 25 years.

I. Positive (10+{-5}=10-5=5)
II. Negative (-2+{-6}=-2-6=-8)
III. Positive (-10-{-20}=-10+20=10)
Hope this helps :)
28=14/15x
28(15)=14/15(15)x
420=14x
420/14=14/14x
30=x
The solution is 30
Step-by-step explanation:
when a line intersects with 2 (or more) parallel lines. then, of course, the intersection angle is the same with every of the intersected lines. otherwise they would not be parallel.
so,
7x - 10 = 60
7x = 70
x = 10
