The data from a survey on the academic degrees earned by students in the United States in 2009 is shown below.

Viefleur [7K]

Answer:

0.23

Step-by-step explanation:

You are given the table

$\begin{array}{cccc}\text{Degree}&\text{Male}&\text{Female}&\text{Total}\\\text{Associate}&298&489&787\\\text{Bachelor}&685&916&1,601\\\text{Master}&260&397&657\\\text{Professional}&47&45&92\\\text{Doctorate}&32&35&67\\\text{Total}&1,322&1,882&3,204\end{array}$

Form this table

Number of associate male students = 298

Total number of male students = 1,322

Relative frequency of male students earning an associate’s degree among all the males earning any degree $=\dfrac{298}{1,322}\approx 0.23$

$\cos( \alpha ) = \frac{5}{13} \\$

$\tan( \alpha ) = \frac{12}{5} \\$

$\tan( \alpha ) = \frac{ \sin( \alpha ) }{ \cos( \alpha ) } \\$

$\frac{12}{5} = \frac{ \sin( \alpha ) }{ \frac{5}{13} } \\$

Multiply sides by 5 / 13

$\frac{5}{13} \times \frac{12}{5} = \frac{5}{13} \times \frac{ \sin( \alpha ) }{ \frac{5}{13} } \\$

$\frac{5 \times 12}{5 \times 13} = \sin( \alpha ) \\$

$\frac{12}{13} = \sin( \alpha ) \\$

$\sin( \alpha ) = \frac{12}{13} \\$

What are the coordinate points to this equation

Andreyy89

Answer:

$\large\boxed{x^2+(y-3)^2=2.25}$

Step-by-step explanation:

The standard form of an equation of a circle:

$(x-h)^2+(y-k)^2=r^2$

(h, k) - center

r - radius

We have the center (0, 3) and the point (-1.5, 3) on the circumference.

The radius is a distance between given points: r = 1.5.

Substitute:

$(x-0)^2+(y-3)^2=(1.5)^2$
