Answer:
b
Step-by-step explanation:
Because the population is too large and it would be impractical to survey the whole population, a sample of the population is chosen to take part in the survey. This sample is taken as been representative of the whole population
Based on the sample, the fraction of students that speak more than one language fluently = 15/90= 0.166667
Population that would speak more than one language fluently = 0.166667 x 1800 = 300
Remark
The general equation for the point slope form is
(y - h) = slope(x - k)
<em><u>Givens</u></em>
given point = (5,7) from which
h = 7
k = 5
slope = m = - 13
Equation
(y - 7) = -13(x - 5) Usually the equation is left like this.
Answer:
C. The statement is false. Geometry is an axiomatic system where the accepted principles are the undefined terms point, line and plane.
Step-by-step explanation:
The 4 basic characteristics of axiomatic systems are:
- Undefined terms (or primitive terms)
- Axioms (or postulates)
- Theorems
- Laws of logic
The undefined terms or primitive terms of geometry are points, lines and planes that at some point meet or join together. This is called incidence, since geometry studies their relationship. E.g. 3 lines that form a triangle on a plane.
Step-by-step explanation:
(2x_5)(x+4)
2x(x+4)_5(x+4)
2x²+8x_5x_20
2x²+3x_20=3x+30
2x²+3x_3x=30+20
2x²=50
√2x²=√50
2x=7.071
2x/2=7.071/2
ans=3.536
