Determine whether the given segments have the same length. Drag and drop each number

Mathematics

s344n2d4d5 [400]3 years ago
6 0

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.

For each set of probabilities, determine whether the events A and B are independent or dependent.
lozanna [386]

Answers:

  • (a) Independent
  • (b) Dependent
  • (c) Dependent
  • (d) Independent

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

Explanation:

If events A and B are independent, then the two following equations must both be true

  • P(A | B) = P(A)
  • P(B | A) = P(B)

This is because the conditional probability P(A|B) means "P(A) when B has happened". If B were to happen, then P(A) must be the same as before. In other words, event B does not affect A, and vice versa.

For part (a), we have P(B) = 1/4 and P(B|A) = 1/4 showing that P(B|A) = P(B) is true, and therefore we can say the events are independent. We don't need the info that P(A) = 1/8.

------------------------

Unlike part (a), part (b) has the answer "dependent" because P(A) = 1/8 and P(A | B) = 1/3 differ in value. Event A starts off at probability 1/8, but then event B occurring means P(A) gets increased to 1/3. The prior knowledge about B changes the chances of A. The P(B) = 1/5 is unneeded.

------------------------

If A and B were independent, then,

P(A and B) = P(A)*P(B)

However,

P(A)*P(B) = (1/4)*(1/5) = 1/20

which is not the same as P(A and B) = 1/6. Therefore the two events are dependent.

------------------------

Refer back to part (a)

P(A) = 1/4 and P(A|B) = 1/4 are identical in value, so P(A|B) = P(A) which leads to the events being independent. Whether we know event B happened or not, it does not affect the outcome of event A. P(B) = 1/9 is unneeded.

Answer:

3.5 X 10^4 < 2.1 x 10^6

Step-by-step explanation:

3.5 X 10^4 < 2.1 x 10^6

The first thing we look at is the exponent

10 ^4 is less than 10^6

10000 < 1000000

If the exponents are the same, then we look at the numbers out front

What's 17 percente of 200?
Margaret [11]

Answer:

34

Step-by-step explanation:

17% of 100 is 17, so you can put that into a proportion, 17/100.  We need to find what the numerator will be if the denominator is 200. Since you multiply 100 by 2 to get to 200, you have to do the same to the top, and 17x2 is 34.

Therefore, the correct answer is 34.

Hope I helped!!!
