4th answer because the ratios are not the same. The ratios need to be the same. 1:2 and 2:4 ratio is the same because the fraction 1/2 is the same as 2/4. So, 3:4 ratio is the same as 9:12 because 3/4 is the same as 9/12. However 7:4 ratio or 7/4 is not the same as 4/3. So they are not similar.

Suppose you deal three cards from a regular deck of 52 cards. What is the probability that they will all be jacks?

andrew-mc [135]

<u>Answer:</u>

Probability of getting three jacks = $\frac { 3 } { 5 2 }$

<u>Step-by-step explanation:</u>

It is given that you deal three cards from a regular deck which contains 52 cards.

We are to find the probability of getting all three Jack cards.

We know that there are a total of 4 jacks in a regular deck of 52 cards.

Therefore, the probability of getting three jacks = $\frac { 3 } { 5 2 }$

Use the slope-intercept form to Graph y=-1/8x+2

noname [10]

Step-by-step explanation:

This is a straight line equation. We only need two points to draw a straight line.

Choose two different numbers, put them into the equation instead of x, and calculate the value of y.

$y=-\dfrac{1}{8}x+2$

for x = 8

$y=-\dfrac{1}{8}\cdot8+2=-\dfrac{8}{8}+2=-1+2=1$

<h2>(8, 1)</h2>

for x = -8

$y==-\dfrac{1}{8}\cdot(-8)+2=\dfrac{8}{8}+2=1+2=3$

<h2>(-8, 3)</h2>

Mark the points in the coordinate system and draw a straight line through the given points.
