Meta-analysis is a statistical procedure that summarizes a large body of evidence from the research literature on a particular topic, allowing the researcher to assess the strength of the relationship between the variables.
<h3>What is
meta-analysis?</h3>
Meta-examination is an instrument by which little, related investigations are distinguished and, through orderly survey, are joined into a typical information pool for a solitary, bigger populace investigation. A meta-investigation is a factual examination that consolidates the consequences of numerous logical examinations. A meta-relapse examination of uncontrolled series of patients with uveal melanoma treated with proton bar treatment has shown that this treatment was related with improved results than brachytherapy. The scientist playing out the meta-examination should make a hierarchical framework prior to separating the information from the singular investigations, as a bookkeeping sheet or data set.

Answer:
Step-by-step explanation:
If 70% passed both, then that means 30% passed either one test, or neither test.
Since 80% passed the first test, we know that 20% of the students failed the first test.
This means that the other 10% of the students came from the 80% that already passed the first test.
These make up 10/80 = 12.5% of the people that passed the first test, meaning your answer is 100-12.5=87.5%
-4*2(3x-7)
-8(3x-7)
8 times 4 is 24 so it would be negative 24
so 3 times 16.3=48.9 then you add 7 which rounds it off it 56
so x is 16.3 thats how you get this expession
-24x +56
