Isabel Briggs Myers was a pioneer in the study of personality types. The personality types are broadly defined according to four

main preferences. Do married couples choose similar or different personality types in their mates? The following data give an indication.
Similarities and Differences in a Random Sample of 375 Married Couples
Number of Similar Preferences Number of Married Couples
 All four                      29
Three                      124
Two                      120
One                      66
None                      36   


Suppose that a married couple is selected at random.
Required:
Use the data to estimate the probability that they will have 0, 1, 2, 3, or 4 personality preferences in common.

Answer:

P ( All four) = 29/375=0.07733

P ( Three A^) = 124/375= 0.33067

P ( Two A^) = 120/375= 0.32

P (One A^) = 66/375= 0.176

P (None A^) = 36/375= 0.096

Step-by-step explanation:

Number of Similar Preferences                  Number of Married Couples

All four                                                                29

Three                                                                 124

Two                                                                     120

One                                                                     66

<u>None                                                                  36                             </u>

<u>Total                                                                      375                        </u>

<u />

We want to determine the probability that they will have 0, 1, 2, 3, or 4 personality preferences in common.

P ( All four) = 29/375=0.07733

P ( Three A^) = 124/375= 0.33067

P ( Two A^) = 120/375= 0.32

P (One A^) = 66/375= 0.176

P (None A^) = 36/375= 0.096

Probability is calculated by favorable outcome divided by the total outcome.

Similarly we obtained the probabilities of the couples that they will have 0, 1, 2, 3, or 4 personality preferences in common.

Answer:

  • See below

Step-by-step explanation:

<u>The roots are:</u>

  • 3, 3, 2 - 3i, 2 + 3i (conjugate of 2 - 3i should be added) and the leading coefficient is - 5

<u>The polynomial is:</u>

  • -5(x - 3)² (x - [2 - 3i]) (x - [2 + 3i]) =
  • - 5(x² - 6x + 9) (x² - 4x + 13) =
  • -5(x⁴ - 10x³ + 46x² - 114x + 117) =
  • -5x⁴ + 50x³ - 230x² + 570x - 585

Ship A receives a distress signal from the southwest, and ship B receives a distress from the same vessel from the north. At wha
Fiesta28 [93]

I've attached an image showing the coordinates of Ship A and Ship B.

Answer:

distressed vessel is located at (1, 1.5)

Step-by-step explanation:

From the image attached, we can see that;

Coordinate of ship A is (3, 4)

Coordinate of ship B is (1, 1)

Now, we are told that Ship A receives a distress signal from the southwest, and ship B receives a distress from the same vessel from the north.

This means that the distressed ship is somewhere in between ship A & B.

To solve this, we will extend the arrow line from Ship A in that same SW direction and we will do the same for ship B in the same North direction. Their point of intersection is where the distressed ship is located.

Now, if we do that, we will see that they will intersect at the point; (1, 1.5)

Thus,distressed vessel is located at (1, 1.5)
