Answer:
2/5
Step-by-step explanation:
Let x = numerator
3 + x = denominator
the numerator and denominator are increased by 1 , the fraction becomes

cross multiply
2(x + 1 ) = 4 + x
2x + 2 = 4 + x
combine like terms
2x - x = 4 - 2
x = 2 = numerator
denominator = 2 + 3 = 5
2/5 fraction
Answer:
Associative Property of Addition
Step-by-step explanation:
Here, in the second line, there are plus signs (+'s), indicating this is addition. But this time, unlike the first line, the numbers are grouped together with parentheses. When numbers are grouped with parentheses, it means it is the Associative property. Because we are adding, it's the associative property of ADDITION.
Hope this helped!
4a²b⁴ - 25x⁶y⁴
(2ab²)² - (5x³y²)²
= (2ab² + 5x³y²)(<span>2ab² - 5x³y²) By difference of two squares</span>
Statistics is related to maths because we study, use and even consider statistic problems with reference to mathematics.
• It is mostly used to find the census, which is maths.
• It is used to find interest rates and other banking terms using statistics, which is again related to math.
• It is also used to find the average people living in a village or panchayat, which is also math.
Therefore I strongly believe that Statistics is Maths.
Thank You!
