Angle between 16 and 18 = 90 + 55 = 145°

$d= \sqrt{16^2+18^2-2*16*18*cos(145^o)}= \\ \\ \sqrt{256+324+471.83}= \sqrt{1051.83} \approx 32$

If the odds against Deborahs winning first prize in a chess tournament are 1 to 11 what is the probability of the event that she

Lemur [1.5K]

Answer: $\dfrac{11}{12}$

Step-by-step explanation:

Given

The odds against winning in a chess tournament are 1 to 11.

Odds is defined as the ratio of the probability of occurrence to the non-occurrence of event.

$\therefore \text{Probability that event will occur is P'=}\dfrac{1}{1+11}\\\\\Rightarrow P'=\dfrac{1}{12}$

Probability of non-occurrence i.e. she wins the first prize is

$\Rightarrow P=1-\dfrac{1}{12}\\\\\Rightarrow P=\dfrac{11}{12}$

Find the distance between (-2, 8) and (11, 2). Round to the nearest hundredth.

MakcuM [25]

Answer:

14.32

Step-by-step explanation:

We can find the distance using the distance formula:

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

We then substitute (-2,8) as $(x_1,y_1)$ and (11,2) as $(x_2,y_2)$ .

$d=\sqrt{(11--2)^2+(2-8)^2} \\d=\sqrt{(13)^2+(-6)^2} \\d=\sqrt{169+36}\\d=\sqrt{205}=14.32$
