The terminal side of θ passes through the point (10, 6). What is the exact value of cos θ in simplified form?
seraphim [82]

Answer:

\frac{5\sqrt{34}}{34}

Step-by-step explanation:

The formula for cos θ is a/r. A is the first number (10) and b is the second number (6). R is the hypoteneuse which can be found through r = \sqrt{a^{2} + b^{2}  }.

In the equation you'd write that as r = \sqrt{10^{2} + 6^{2} which can be simplified to \sqrt{136.

You end up with \frac{10}{\sqrt{136} } and you simplify this by doing \frac{10 }{\sqrt{136} } * \frac{\sqrt{136} }{\sqrt{136} }, ending with the result of \frac{5\sqrt{34}}{\sqrt{34} }.

(I also got this answer right on the test.)

A roulette wheel has the numbers 1 through 36, 0, and 00. A bet on four numbers pays 8 to 1 (that is, if you bet $1 and one of t
Natasha_Volkova [10]

Answer:

Lose $0.05

Step-by-step explanation:

There are 38 possible spots on the roulette wheel (numbers 1 to 36, 0 and 00).

If the player can choose four numbers on single $1 bet, his chances of winning (W) and losing (L) are as follows:

P(W) = \frac{4}{38} \\P(L) = 1-P(W) = 1-\frac{4}{38} \\P(L) = \frac{34}{38}

The expected value of the bet is given by the probability of winning multiplied by the payout ($8), minus the probability of losing multiplied by the bet cost ($1)

EV=\frac{4}{38}*\$8 -\frac{34}{38}*\$1\\EV= -\$0.05

On each bet, the player is expected to lose 5 cents ($0.05).
