Answer:

a You must choose at least 3 marbles

Step-by-step explanation:

If the probability is equally likely that you will choose a red or blue marble (1/2)

Then the marbles will need to be the same size or you will know which the color of the marble by the size.

There needs to be the same number of marbles, or you will be more likely to pick the color with more marbles of that color

If you look, you will pick the color of the marble you want.

The probability is determined by the number of marbles in the bag, not by the number you choose

Let (8,−3) be a point on the terminal side of θ. Find the exact values of cosθ, cscθ, and tanθ.

denis23 [38]

Answer:

$\text{Cos}\theta=\frac{\text{Adjacent side}}{\text{Hypotenuse}}=\frac{x}{R}=\frac{8}{\sqrt{73}}$

$\text{Csc}\theta=-\frac{\sqrt{73}}{3}$

$\text{tan}\theta =\frac{\text{Opposite side}}{\text{Adjacent side}}=\frac{y}{x}=\frac{-3}{8}$

Step-by-step explanation:

From the picture attached,

(8, -3) is a point on the terminal side of angle θ.

Therefore, distance 'R' from the origin will be,

R = $\sqrt{x^{2}+y^{2}}$

R = $\sqrt{8^{2}+(-3)^2}$

= $\sqrt{64+9}$

= $\sqrt{73}$

Therefore, Cosθ = $\frac{\text{Adjacent side}}{\text{Hypotenuse}}=\frac{x}{R}=\frac{8}{\sqrt{73}}$

Sinθ = $\frac{\text{Opposite side}}{\text{Hypotenuse}}=\frac{y}{R}=\frac{-3}{\sqrt{73} }$

tanθ = $\frac{\text{Opposite side}}{\text{Adjacent side}}=\frac{y}{x}=\frac{-3}{8}$

Cscθ = $\frac{1}{\text{Sin}\theta}=\frac{R}{y}=-\frac{\sqrt{73}}{3}$

zloy xaker [14]

Let
X=<span>the original price of the pair of headphones
then
if the % </span>off sale is 40--------------- > (1-0.40)*X=<span>$36
x=36/0.60=60

the answer is
</span>the original price of the pair of headphones was $60
