Remark

You must use the sin law to find this.


\dfrac{Sin(75)}{22} = \dfrac{Sin(x)}{12}

Multiply through by 12

12 * \dfrac{Sin(75)}{22} = \dfrac{Sin(x)}{12} *12


\dfrac{12*sin(75)}{22} = \text{sin(x)}

0.5269 = sin(x)


Now you have to use the inverse of the sine function.

Use your calculator for that

2nd F

sin-1

(0.5269)

= 31.79 degrees. <<<<<< Answer.


There sometimes is a second answer. I don't think there is in this case.

The data show the ages of 13 people attending a dinner party. 37, 42, 44, 46, 47, 49, 51, 53, 54, 55, 57, 61, 63 a. Find the min
NemiM [27]

Answer: Median: 50, Minimum Value: 37, Maxium Value: 63, First Quartile: 44, Third Quartile: 57  

Step-by-step explanation:

To find the median we have to line up the number from least to greatest. Since the number is even we have two numbers.

(37, 42, 44, 46, 47, )(49, 51,)(54, 55, 57, 61, 63)

            |                          |                        |

  1st  Quartile        2nd Quartile     3rd Quratile

49 + 51 = 100 ÷ 2 = 50

Median = 50

The minimum value is the least number, therefore 37

The maxium number is the greatest number, therefore 63

The first quartile is the middle number in the first quartile, therefore 44

The third quartile is the middle number in the third quartile, therefore 57

I hope this helps!
