How many solutions does this linear system have?
Naily [24]
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 p : q = 5 : 2 and q : r = 4 : 3, find the ratio of p : q : r​
yaroslaw [1]

Answer:

p : q : r = 10 : 4 : 3

Step-by-step explanation:

Expressing the ratio in fractional form

\frac{q}{r} = \frac{4}{3} ( cross- multiply )

4r = 3q ( divide both sides by 4 )

r = \frac{3}{4} q = \frac{3}{4} × 2 = \frac{3}{2}

Then

p : q : r

= 5 : 2 : \frac{3}{2} ( multiply all parts by 2 )

= 10 : 4 : 3

hichkok12 [17]

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%
