Keith_Richards [23]3 years ago
5 0

Answer:

55.13%

Step-by-step explanation:

Your comparison is 215 men out of 390 people.

Divide 215 by 390 and then multiply by 100 to get your percentage

215 ÷ 390 = 0.5513

0.5513 × 100 = 55.13%

What is the equation for the points (-3,1) and (9,7)
Scorpion4ik [409]

Answer:

The equation of line with given points is 2Y - X - 5 = 0

Step-by-step explanation:

Given points are ( - 3 , 1)   and   (9 , 7)

Equation of line is y = mx +c

where m is the slop of line

Now m = \frac{y2 - y1}{x2 - x1}

Or,    m = \frac{7 - 1}{9 + 3}

so, slop = \frac{6}{12}

∴   slop = \frac{1}{2}

Now the equation of line with points ( -3 , 1) and slop m is :

Y - y1 = m ( X - x1)

Or, Y - 1 =  \frac{1}{2} (X + 3)

Or, 2Y - X - 5 = 0

Hence The equation of line with given points is 2Y - X - 5 = 0 Answer

Determine if the following system of equations has no solutions, infinitely many
Vesnalui [34]

Answer:

The system has infinitely many solutions

Step-by-step explanation:

we have

5x+3y=9 ----> equation A

-10x-6y=-18 ----> equation B

Multiply by -2 both sides equation A

-2(5x+3y)=-2(9)

-10x-6y=-18 ----> equation C

Compare equation B and equation C

The equations are identical (is the same line)

therefore

The system has infinitely many solutions

Is a consistent dependent system
