Answer:

2/3 of the class is now boys

Step-by-step explanation:

If you start with 3/5 of 20 is boys that would mean there were 12 boys. If you add 4 more that makes it 16/24 and you can simplify that fraction to 4/6 and simplified even further is 2/3.

Write equation of the line containing (6,3) and (4,1) Group of answer choices y = -1x + 5 y = 1x - 3 y = 1x + 5 y = -1x + 3

Natalka [10]

Answer:

y = x - 3

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = (6, 3) and (x₂, y₂ ) = (4, 1)

m = $\frac{1-3}{4-6}$ = $\frac{-2}{-2}$ = 1 , then

y = x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (4, 1 )

1 = 4 + c ⇒ c = 1 - 4 = - 3

y = x - 3 ← equation of line

lapo4ka [179]

Probability

There are:

5 anthropology students

3 sociology students

4 psychology students

5 + 3 + 4 = 12 students in total

The probability that one randomly selected student is for anthropology is:

$p=\frac{5}{12}$

Note we have divided the number of favorable cases by the total cases

Complete the square for a circle. For #42.

makkiz [27]

we are given

$2x^2+2y^2-28x+20y+20=0$

we can see that

each terms are multiple of 2

so, we can factor out 2

$2(x^2+y^2-14x+10y+10)=0$

we can divide both sides by 2

$x^2+y^2-14x+10y+10=0$

we can rearrange it

$x^2+-14x+y^2+10y+10=0$

now, we can move 10 on right side

$x^2+-14x+y^2+10y=-10$

$x^2+-2*7*x+y^2+2*5*y=-10$

now, we can add both sides 7^2 and 5^2

$x^2+-2*7*x+7^2+y^2+2*5*y+5^2=-10+7^2+5^2$

$(x-7)^2+(y+5)^2=-10+7^2+5^2$

we can simplify it

$(x-7)^2+(y+5)^2=64$

we can also write as

$(x-7)^2+(y+5)^2=8^2$ ..............Answer
