The experimental data suggest that

\mathbb P(\text{red})\approx\dfrac{38}{75}
\mathbb P(\text{blue})\approx\dfrac{23}{75}
\mathbb P(\text{green})\approx\dfrac{11}{75}
\mathbb P(\text{yellow})\approx\dfrac3{75}

Because the marble is replaced after being drawn, and so the number of marbles of a given color remains the same, the event of drawing any given color is independent of what was drawn before. So

\mathbb P(\text{2 consecutive yellows})\approx\dfrac3{75}\cdot\dfrac3{75}=\dfrac1{625}

Answer:

x = 250°

Step-by-step explanation:

"Angle formed between a chord and tangent intersecting on a circle measure the half of the intercepted arc"

From the figure attached,

Angle between the chord and the tangent = 55°

Measure of intercepted arc (minor arc AB) = h°

Therefore, 55° = \frac{1}{2}(h)

h=110^0

And m(minor arc AB) + m(major arc AB) = 360°

h° + x° = 360°

110° + x° = 360°

x° = 360° - 110°°

x = 250°

Therefore, measure of the intercepted arc is 250°.

Please help show work<br><br> 3√(125) -√(16) = ?
Anna007 [38]
First, simplify the radicals
√125=√(5*5*5)=(√5*5)(√5)=5√5
so 3√125=3*5√5=15√5

and √16=4
so
15√(5)-4 is the simplified version
