75 + 50x = 25 + 70x a, 5 b, 5/6 c, 2 d, 2.5

Stells [14]

Answer:

Step-by-step explanation:

Let's solve your equation step-by-step.

75+50x=25+70x

Step 1: Simplify both sides of the equation.

50x+75=70x+25

Step 2: Subtract 70x from both sides.

50x+75−70x=70x+25−70x

−20x+75=25

Step 3: Subtract 75 from both sides.

−20x+75−75=25−75

−20x=−50

Step 4: Divide both sides by -20.

−20x

−20

−50

−20

Consider the line segment YZ with endpoints Y(-3,-6) and Z(7,4). What is the y-coordinate of the midpoint of line segment YZ?

tatiyna

Given:

Consider the line segment YZ with endpoints Y(-3,-6) and Z(7,4).

To find:

The y-coordinate of the midpoint of line segment YZ.

Solution:

Midpoint formula:

$Midpoint=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)$

The endpoints of the line segment YZ are Y(-3,-6) and Z(7,4). So, the midpoint of YZ is:

$Midpoint=\left(\dfrac{-3+7}{2},\dfrac{-6+4}{2}\right)$

$Midpoint=\left(\dfrac{4}{2},\dfrac{-2}{2}\right)$

$Midpoint=\left(2,-1\right)$

Therefore, the y-coordinate of the midpoint of line segment YZ is -1.

The number of girls in three-child families in a certain geographic area is investigated. Of 212 families with exactly three chi

Sati [7]

Answer:

p = 0.513

Step-by-step explanation:

There are 212 families with exactly 3 children. So in all, there are 212*3 = 636 children.

Of those,

The number of girls is:

81 + 76*2 + 31*3 = 326

That is, 326 girls out of 636 children.

Then

$p = \frac{326}{636} = 0.513$
