PLEASE HELP! A juice company gives prizes to anyone finding specially marked caps on its juice bottles. You and your friends buy
laiz [17]

The odds in favor of winning a prize in the contest of the juice company which gives prizes to anyone finding specially marked caps is 3.2.

<h3>What is odds against?</h3>

In probability, the term odds against is the ratio of probability of non occurring a favorable event to the probability of occurring a favorable event. It can be given as,

\text{odd against}=\dfrac{P(\overline A)}{P(A)}

Here, P(\overline A) is the probability of not occurring a favorable event, and P(A) is the probability of occurring a favorable event.

A juice company gives the prizes to anyone finding specially marked caps on its juice bottles. The 4 bottles have winning cap in 20 bottles. Thus, the probability of winning is,

P(A)=\dfrac{4}{20}\\P(A)=\dfrac{1}{5}

The probability of not winning is,

P(\overline A)=1-\dfrac{1}{5}\\P=\dfrac{4}{5}

Thus, the odd against the winning is,

\text{odd against}=\dfrac{\dfrac{4}{5}}{\dfrac{1}{4}}\\\text{odd against}=\dfrac{16}{5}\\\text{odd against}=3.2

Thus, the odds in favor of winning a prize in the contest of the juice company which gives prizes to anyone finding specially marked caps is 3.2.

Y varies directly as xy equals 5 when X is 8 how do you find y when X is 9
FrozenT [24]

Given, y varies directly as x

So,

y=c\cdot x

Where c is a constant

When y equals 5 when x is 8

So,

\begin{gathered} 5=c\cdot8 \\ c=\frac{5}{8} \\  \end{gathered}

So, the relation between y and x

y=\frac{5}{8}x

now , when x = 9

Substitute with x to find y

y=\frac{5}{8}\cdot9=\frac{45}{8}

So, the answer is option 2. y = 45/8

The length of a rectangle is three times it's width. If the perimeter of the rectangle is 64, find its length and width
wlad13 [49]

set up an equation for the perimeter

l = length w = width

2l + 2w = 64

set up another equation as you know the length is 3 times the width

w = 3l

subsitute w = 3l into the 2l + 2w = 64

2l + 2(3l) = 64

solve for l

2l + 6l = 64

8l = 64

<em><u>length</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>8</u></em>

subsitute into w = 3l

w = 3(8)

<em><u>width</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>2</u></em><em><u>4</u></em>
