Determine whether the given segments have the same length. Drag and drop each number
s344n2d4d5 [400]

Answer:

Step-by-step explanation:

Length of a segment between two points (x_1,y_1) and (x_2,y_2) is given by the formula,

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Coordinates of extreme ends of BC and EF are,

B(1, 4), C(3, -2), E(-3, -2) and F(-1, 1)

Length of BC = \sqrt{(1-3)^2+(4+2)^2}

                      = \sqrt{4+36}

                      = 2\sqrt{10} ≈ 6.32 units

Length of EF = \sqrt{(-3+1)^2+(-2-1)^2}

                     = \sqrt{4+9}

                     = \sqrt{13} ≈ 3.61 units

The length of BC is 6.32. The length of EF is 3.61.So, BC and EF don't have the same length.

!!!!!!!!!!!! Help!!!!!!!!!
Lisa [10]
1) D is your answer.

Isolate the y:

2x = 3y - 5

first add 5 from both sides

2x (+5) = 3y - 5 (+5)

Next, divide 3 from both sides to isolate the y

(2x + 5)/3 = (3y)/3

y = (2x + 5)/3

2) None of the above is your answer


Plug in points for each equation. None of them work for more than 1 or 2 points. (they are not true for all points) ∴ None of the above is your answer


hope this helps

If the probability of being hospitalized during a year is 0.15 find the probability that no one in the family of 4 will be hospi
Goryan [66]

The probability that no one in the family of 4 will be hospitalized during a year is 0.52

Step-by-step explanation:

The probability for a person to be hospitalized during one year is

p(h)=0.15

As a consequence, the probability for a person of NOT being hospitalized during one year is

p(h^{-1})=1-0.15=0.85

If we have 4 people in the family, the probability of each of them of NOT being hospitalized during the year is independent from the probability of the others - therefore, these are independent events. This means that the total probability of the 4 people of not being hospitalized during a year is:

p(h^{-1})^4=(0.85)^4=0.52

So, the probability that no one in the family of 4 will be hospitalized during a year is 0.52.
