Answer:

x-int:(-2,0)(-4,0) . y-int:(0,8)

Step-by-step explanation:

y = x2+6x+8 and y = (x+2)(x+4)

x-int:

x+2=0

x= -2

(-2,0)

x-int:

x+4=0

x=-4

(-4,0)

y-int: plug 0 for x

y=(0+2)(0+4)

y=8

Given: △PRS, RS=10 m∠P=45°, m∠S=60° Find: Perimeter of △PRS

Keith_Richards [23]

The law of sines can be used to find the missing side lengths.

... RP = sin(60°)/sin(45°)·10 = 10√(3/2) ≈ 12.247

... PS = sin(75°)/sin(45°)·10 ≈ 13.660

Then the perimeter is

... perimeter = RS + RP + PS

... = 10 + 12.247 + 13.660 ≈ 35.91 . . . .units

12. In Europe, 88% of all households have a TV. 51% of all households have a TV and VCR. What is the probability that a househol

PSYCHO15rus [73]

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.
