Answer:

  about 3.492

Step-by-step explanation:

The distance between points in polar coordinates can be found using the Law of Cosines. For vector magnitudes a and b, and angular difference C, the distance between them (c) can be found from ...

  c^2 = a^2 +b^2 -2ab·cos(C)

  = 7^2 +5^2 -2(7)(5)cos((217/180π -(-23/36)π)

  = 74 -70cos(332°) ≈ 12.1937

  c = √12.1937 ≈ 3.492

The distance between the given points is about 3.492 units.

The graph represents the normal distribution of recorded weights, in pounds, of cats at a veterinary clinic.
diamong [38]

Answer:

<em>B)</em><em> 8.9 lbs </em>

<em>C)</em><em> 9.5 lbs </em>

<em>D)</em><em> 9.8 lbs </em>

<em>E)</em><em> 10.4 lbs</em>

Step-by-step explanation:

From the graph, 9.5 is the mean of the sample and 0.5 is the standard deviation of the sample.

As we have to find the weights that lie within the 2 standard deviations of the mean i.e

=9.5\pm 2(0.5)

=8.5,10.5

Among the given weights only 8.9 lbs, 9.5 lbs, 9.8 lbs, 10.4 lbs will lie within 2 standard deviations of the mean.

ivolga24 [154]

Answer:

1. a=3, b = 2, c = 1.

2. a=2, b=3, c=4, d=6.

3. a = 9, b = 3.

Step-by-step explanation:

1.  3 | 21   is a counterexample  because 3 does not divide into  2 or 1.

2. 23 | 46 is a counterexample because 2 does not divide into 3.

3. 9 | 3^2 is a counterexample because 9 does not divide into 3.
