Answer:

1. (19x - 49)+(5x + 37) = 180

2. 77°

Step-by-step explanation:

1. Since the two arc measures will equal 180°, you can write the equation (19x - 49)+(5x + 37) = 180

2. By solving the equation, we can find that x=8. Plugging in the value for arc CD's equation, you will find that it is equal to 77°.

A population has 75 observations. One class interval has a frequency of 15 observations. The relative frequency in this category

vovangra [49]

Answer:

The relative frequency in this category is 0.2

Step-by-step explanation:

The relative fraquency of a category is given by the number of observations in this category divided by the total number of observations.

In this question:

The category of interest has 15 observations.

In total, the population has 75 observations.

So the relative frequency is:

$\frac{15}{75} = \frac{1}{5} = 0.2$
