3y=-2x-5

y=(-2/3)x-5/3

y-3=(-2/3)(x-1)

A box contains ten sealed envelopes numbered 1,..., 10. The rst ve contain no money, the next three each contain $5, and there i
Neporo4naja [7]

Answer:

a)

P(X = 0) = 5/10

P(X = 5) = 3/10

P(X = 10) = 2/10

b)

E = 0·5/10 + 5·3/10 + 10·2/10 = 3.5

V = 0^2·5/10 + 5^2·3/10 + 10^2·2/10 - 3.5^2 = 15.25

A box of stuffing costs $1.99 for 16 oz. Find the unit cost, round to the nearest hundredth.
Misha Larkins [42]

The given ratio is:

\frac{\text{ \$1.99}}{16oz}

To find the unit cost per ounce, we can use proportions as follows:

\frac{\text{ \$1.99}}{16oz}=\frac{x}{1oz}

Now, solve for x:

\begin{gathered} x=\frac{1oz\cdot\text{ \$1.99}}{16oz} \\ x=0.12 \end{gathered}

The cost per ounce (unit cost) is then $0.12/oz

The figure below shows a right triangle:
il63 [147K]

Answer:

The correct answer is option C.  Cos x

Step-by-step explanation:

<u>Points to remember</u>

<u>Trigonometric ratios </u>

Sin θ  = Opposite side/Hypotenuse

Cos θ = Adjacent side/Hypotenuse

Tan θ = Opposite side/Adjacent side

From the figure we can see that, a right triangle with angles  and sides are given.

<u>To check the options</u>

1) Sin x = Opposite side/Hypotenuse  = p/q

2). Cos y = Adjacent side/Hypotenuse  =p/q

3). cos x= Adjacent side/Hypotenuse  = r/q

4). tan y = Opposite side/Adjacent side = r/p

Therefore the correct answer is option C.  Cos x
