the large bag is 5/6 lb, the smaller bags will be 1/3 lb, so it should be 5/6 ÷ 1/3

$\bf \cfrac{5}{6}\div \cfrac{1}{3}\implies \cfrac{5}{\underset{2}{~~\begin{matrix} 6 \\[-0.7em]\cline{1-1}\\[-5pt]\end{matrix}~~}}\cdot \cfrac{~~\begin{matrix} 3 \\[-0.7em]\cline{1-1}\\[-5pt]\end{matrix}~~}{1}\implies \cfrac{5}{2}\implies 2\frac{1}{2}$

Answer:

5/2 or 2 1/2

Step-by-step explanation:

This question is asking "How many times does 1/3 go in 5/6"

So, we divide 5/6 by 1/3

5/6 / 1/3 = 5/6 * 1/3 = 5/6*3 = 5/2 or 2 1/2

One card is randomly selected from a deck of cards. Find the odds against drawing an eight The odds against drawing an eight are

ipn [44]

Answer:

The odds against drawing an eight are $\frac{12}{13}$

Step-by-step explanation:

If there are 52 cards in a deck, 13 cards a suit and 4 suits, that means there are four eights in the deck, one of every suit.

That means, the probability of drawing an eight is:

$P_{eight}=\frac{number of eights}{cards} =\frac{4}{52}=\frac{1}{13}$

As we want to find the odds against drawing an eight, we want to find the probability of not drawing an eight.

The probability of drawing or not drawing an eight is one (the probability of taking a card if we take a card), and as they are not independent, we know that we have to sum those probabilities:

$P_{card} =P_{eight}+P_{not eight}= 1$

Then, we can find the probability of not drawing an eight:

$P_{not eight}= 1- P_{eight}=1-\frac{1}{13} =\frac{12}{13}$

That means, in average, 12 out of 13 times we will not draw an eight.

What is the minimum value of the graph of y=sin x assumes

Alex

Short answer: - 1
The first thing you should do is draw this or get a program to do it. I use desmos. It is included. The graph shows one complete cycle every 2*pi intervals (or 360 degrees.)

You will find no lower value that y = - 1 (nor any value greater than y = 1)

(80 POINTS) What rule describes a dilation with a scale factor of ½ and the center of dilation at the origin?

lesya [120]

Answer:

Step-by-step explanation:

(x, y) -> (1/2x, 1/2y)

When you dilate a side, point, etc, you are multiplying the original dimension by the scale factor. That is represented in option C: the original x and y are multiplied by the scale factor, 1/2! Hope that helps! :)
