$P(A|B)=\dfrac{P(A\cap B)}{P(B)}\\\\
P(A|B)=\dfrac{\dfrac{3}{4}}{\dfrac{4}{5}}\\\\
P(A|B)=\dfrac{3}{4}\cdot\dfrac{5}{4}\\\\
P(A|B)=\dfrac{15}{16}$

M×10-m×2=8 fill in the blanks as m

son4ous [18]

M*10-m*2=8
10m-2m=8
8m=8
Divide both sides by 8:
m=8

Fill in the m's:
1*10-1*2=8
10-2=8
8=8

Hope this helps :)

(06.02 mc) the equation of line cd is y=3x-3. Write an equation of a line perpendicular to line cd in slope intercept form that

Fynjy0 [20]

Answer:

y = - $\frac{1}{3}$ x + 2

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 )

y = 3x - 3 ← is in slope- intercept form

with slope m = 3

Given a line with slope m then the slope of a line perpendicular to it is

$m_{perpendicular}$ = - $\frac{1}{m}$ = - $\frac{1}{3}$ , hence

y = - $\frac{1}{3}$ x + c ← is the partial equation of the perpendicular line

To find c substitute (3, 1) into the partial equation

1 = - 1 + c ⇒ c = 1 + 1 = 2

y = - $\frac{1}{3}$ x + 2 ← equation of perpendicular line

John is building a fence around his home currently his fence measures 14 feet on each side but he wants to increase only the wid

nalin [4]

Answer:

The dimensions of rectangular fence are 14 feet and 20 feet.

Step-by-step explanation:

We are given the following in the question:

Length of rectangular fence = 14 feet

Width of fence = (14+x) feet

Area of rectangular field = 280 square feet

Area of rectangular field =

$A= \text{Length}\times \text{Width}$

Putting the values, we get,

$280 = 14(14+x)\\\\14 + x = \dfrac{280}{14}\\\\14 + x = 20\\x =20-14\\x = 6$

Thus, the dimensions of rectangular fence are 14 feet and 20 feet.
