Reil [10]
I would make the equation 800x=120, x representing the decimal form of the unknown percentage

800x=120
x=0.15 (divide both sides by 800)

Then move the decimal point twice to the right to get 15%

Hope this helps

KonstantinChe [14]

Answer:

P(Negative | Yes) = 0.0486

Step-by-step explanation:

Given

\begin{array}{ccc}{} & {Yes} & {No} & {Positive} & {137} & {24} & {Negative} & {7} & {132} \ \end{array}

Required

P(Negative | Yes)

This is calculated as:

P(Negative | Yes) = \frac{n(Negative\ n\ Yes)}{n(Yes)}

So, we have:

P(Negative | Yes) = \frac{7}{137+7}

P(Negative | Yes) = \frac{7}{144}

P(Negative | Yes) = 0.0486

Write the expression as the sine, cosine, or tangent of an angle.

\bf \textit{Sum and Difference Identities}
\\ \quad \\
sin({{ \alpha}} + {{ \beta}})=sin({{ \alpha}})cos({{ \beta}}) + cos({{ \alpha}})sin({{ \beta}})
\\ \quad \\
\boxed{sin({{ \alpha}} - {{ \beta}})=sin({{ \alpha}})cos({{ \beta}})- cos({{ \alpha}})sin({{ \beta}})}

\bf cos({{ \alpha}} + {{ \beta}})= cos({{ \alpha}})cos({{ \beta}})- sin({{ \alpha}})sin({{ \beta}})
\\ \quad \\
cos({{ \alpha}} - {{ \beta}})= cos({{ \alpha}})cos({{ \beta}}) + sin({{ \alpha}})sin({{ \beta}})\\\\

Using your knowledge of circles, label the following on the given diagram: chord, tangent, radius, secant, point of tangency and
Tanzania [10]
The purple line is tangent. Tangent line intersects a circle in only 1 point
The yellow dot is the point of tangency. It is the point where tangent line touches the circle
The light blue line is secant. Secant line intersects a circle in 2 points
The red line is the radius. Radius is the distance from center to the outer rim of the circle.
The green line is the diameter. It is the line passing through the center of a circle. It measures twice the radius
The gray line is the chord. Chord is the line whose endpoints lie on the circle.
Arc AB is a minor arc
Arc ABCD is a major arc
