B. y=2x-5
-4y=8x-20
y=-2x+5
2x-5=-2x+5
x=2.5
2x*2.5-5=0
-2x*2.5+5=0
so (2.5,0)
Given:
is the transversal that intersects the lines r and s.
Required:
Pairs of alternate exterior angles.
Explanation:
Line q intersects the lines r and s.
The alternate exterior angles are,
Answer:
Thus the required answer is option 2.
Answer:
p : q : r = 10 : 4 : 3
Step-by-step explanation:
Expressing the ratio in fractional form
= 
( cross- multiply )
4r = 3q ( divide both sides by 4 )
r = 
q = × 2 = 
Then
p : q : r
= 5 : 2 : ( multiply all parts by 2 )
= 10 : 4 : 3
Answer:
Jones(20%), Smiths(30%)
Step-by-step explanation:
The relative dispersion of a data set is the ratio of its standard deviation to its arithmetic mean.
Mr. and Mrs. Jones' neighborhood mean family income is $45,000 with a standard deviation of $9,000.
Their Relative Dispersion is given as:
Standard Deviation: Mean
9000:45000
1:5
Expressed as a Percentage: (1/5)x100=20%
The Relative Dispersion of the family incomes in Mr. and Mrs. Jones' neighborhood is 20%
Mr. and Mrs. Smith's neighborhood mean family income is $100,000 and the standard deviation is $30,000.
Their Relative Dispersion is given as:
Standard Deviation: Mean
30000:100000
3:10
Expressed as a Percentage: (3/10)x100=30%
The Relative Dispersion of the family incomes in Mr. and Mrs. Smith's neighborhood is 30%
