Answer:

0.579  is the probability that a household has a VCR given they have a TV.

Step-by-step explanation:

We are given the following in the question:

Probability of all households have a TV = 88% = 0.88

P(T) = 0.88

Probability of all households have a TV and VCR = 51% = 0.51

P(T\cap V) = 0.51

We have to find the probability that a household has a VCR given they have a TV.

The conditional probability is given by:

P(V|T) = \displaystyle\frac{P(V\cap T)}{P(t)} = \frac{0.51}{0.88} = 0.579

0.579  is the probability that a household has a VCR given they have a TV.

Need help solving for X
artcher [175]
X+10=110-4x

-x from both sides

10=110-5x

subtract 110 from both sides

-100=-5x

divide both sides by -5

x= 20

Solve the system by elimination. . 4x-9y=-21 , -4x-3y=9
Ivan
(-3, 1)
4x-9y=-21
+-4x-3y=9
-12y= -12
y=1

4x- 9(1)= -21
4x-9=-21
+9 +9
4x= -12
x=-3

Determine whether y varies with x. If so, find the constant of variation and write the function rule.
ira [324]

Answer:  Yes, y does vary directly with x.

Constant of variation = 1/4

The function rule is  y = (1/4)x

=========================================================

Explanation:

Let's assume that y does vary directly with x.

If that's the case, then we have an equation in the form y = kx, where k is the constant of variation.

Solving for k gets us k = y/x

For each row, divide the y value over the x value

  • row one: k = y/x = 14/56 = 0.25
  • row two:  k = y/x = 20/80 = 0.25
  • row three: k = y/x = 22/88 = 0.25

Each row yields the value k = 0.25 and it fully confirms y does vary directly with x.

So y = kx becomes y = 0.25x as the function rule, which is equivalent to y = (1/4)x
