Common ratio = a2 / a1 or a3/a2
= 16/64 = 1/4

In short, Your Answer would be 1/4

Hope this helps!

How many intersections are there of the graphs of the equations below? 1/2x + 5y = 6 3x + 30y = 36 none one two infinitely many

juin [17]

Solve both equations 1/2x + 5y = 6 becomes y = -1/10x + 5/6 and 3x +30y = 36 becomes y = -1/10x + 36/30. Since both equations have the same slope..1/10 the lines are going to be parallel since the constant is different 5/6 vice 36/30. They will never cross.

You are at a family reunion and the cooler contains ten bottles of soda; four Sprite, three Dr. Pepper, and three Cherry Coke. T

Answer:

<em></em> $Probability = \frac{18}{1860480}$ <em></em>

<em></em>

Step-by-step explanation:

Given

Soda = 10

Sprite = 4

Dr. Pepper = 3

Cherry Coke = 3

Required

Determine the probability of picking Dr. pepper the fourth and fifth

First, we need to sum up the number of drinks

$Total = 10 + 4 + 3 + 3$

$Total = 20$

First Selection: Dr. Pepper

$P_1= \frac{3}{20}$

Since its probability without replacement;

<em>At this stage: Dr. Pepper = 2 and Total = 19</em>

Second Selection: Cherry Coke

$P_2= \frac{3}{19}$

<em>At this stage: Dr. Pepper = 2; Cherry Coke = 2 and Total = 18</em>

<em></em>

Third Selection: Cherry Coke

$P_3= \frac{2}{18}$

$P_3= \frac{1}{9}$

<em>At this stage: Dr. Pepper = 2; Cherry Coke = 1 and Total = 17</em>

<em></em>

Fourth Selection: Dr. Pepper

$P_4= \frac{2}{17}$

<em>At this stage: Dr. Pepper = 1; Cherry Coke = 1 and Total = 16</em>

<em></em>

Fifth Selection: Dr. Pepper

$P_5= \frac{1}{16}$

<em></em>

<em>Multiply the calculated probabilities, to give the required probability</em>

<em></em> $Probability = P_1 * P_2 * P_3 * P_4 * P_5$ <em></em>

<em></em> $Probability = \frac{3}{20} * \frac{3}{19} * \frac{1}{9} * \frac{2}{17} * \frac{1}{16}$ <em></em>

<em></em> $Probability = \frac{3 * 3 * 1 * 2 * 1}{20 * 19 * 18 * 17 * 16}$ <em></em>

<em></em> $Probability = \frac{18}{1860480}$ <em></em>
