<span>7 billion is 10 times greater than 700 million.
7,000,000,000/700,000,000=10</span>
I think it is 4,4 because when i graphed it turned out like that al 7 are
-2,2
-1,1
0,0
1,1
2,2
3,3
4,4
this is what i got i might be wrong because it might not be what you meant but i interpreted this way so i did it this way
Answer:
D. Mathematical expressions for the relationships
Step-by-step explanation:
Quantitative analysis also called QA for short is the technique that tries to understand behaviour by using mathematical and statistical modeling, measurement and research. A quantitative analyst aims to represent a given reality in terms of numerical value. This can be achieved by using mathematical formulas and expressions to explain the relationships that exists between the variables. The data analyzed are usually gotten from polls and questionnaires or in general, well structured research instruments.
Answer:
x^2 -2xy -10y^2
x^2 -9xy +4 y^2
3x^3 +6x^2 -24 x +27
Step-by-step explanation:
3x^2-5xy -6y^2 -( 2x^2 -3xy+4y^2)
= 3x^2- 2x^2 -5xy +3xy-6y^2 -4 Y^2
= x^2 -2xy -10y^2
2x^2−5xy+y^2 -( x^2+4xy−3y^2)
=2 x^2 -x^2 -5xy -4xy +y^2 +3 y^2
=x^2 -9xy +4 y^2
7x^3−16x+18- (4x^3−6x^2+8x−9)
= 7x^3 -4x^3 + 6x^2-16x- 8x +18 +9
=3x^3 +6x^2 -24 x +27
3,300,000 deaths/year x 1 year/365 days x 1 day/24 hour x 1 hour/60 min → 3,300,000/525,600 → 6.2785388128 deaths/minute
