Answer:
Governments, need to know how many inhabitants currently live in the country and how many there will be in the future. From this they can plan and make better decisions regarding the construction of schools, hospitals, roads, and more.
Allright we know that the total number of tiles is 50 so we can assume that if you pick the first tile and its yellow ther is a (5/50) chance to pick it up and then REPLACED meaning that it is put back so you have still 50 tiles to choose from, if then you choose a green tile you have a (15/50) chance of picking it up
(5/50)*(15/50)=0.03 YOU HAVE A 3 PERCENT CHANCE!!!:D
^This is to calculate the probability of picking it in that order)^
Answer:
(x-1)(x+5)=0
x=1; x=-5
Step-by-step explanation:
x²+4x=5
x²+4x+2²=5+2²
(x+2)²=3²
(x+2)²-3²=0
(x+2-3)(x+2+3)=0
(x-1)(x+5)=0
(x-1)=0 ; x=1
(x+5)=0; x= - 5
Answer:
2 irrational solutions
Step-by-step explanation:
using the quadratic formula:
3x²−x−5=0
where a = 3, b = -1 and c = -5, plug in those values in the quadratic formula
you get two solutions:
both can be written as:
They are irrational as they cannot be written in the form p/q where p and q are whole numbers (integers)
