$f(x)=4x+k/7\\
f(- \frac{2}{3} )=- \frac{8}{3} +k/7=0\quad\Rightarrow\quad k= \frac{56}{3}$

Loretta places 20 red tiles in a bag. How many blue tiles must be added to the bag to make the probability of randomly drawing a

Galina-37 [17]

Answer:

If the number of blue tiles in the bag is 180, then the probability of randomly drawing a red tile equal to 1/10.

Step-by-step explanation:

Total number of red tiles in a bag = 20

Let us assume the number of blue tiles in a bag = p

So, the total number of tiles in a bag = Red Tiles + Blue tiles

= 20 + p

Now, let us find the probability of drawing a red tile:

$\textrm{The probability of drawing a red tile} = \frac{\textrm{Total Number of red tiles}}{\textrm{Total Tiles}}\\= \frac{20}{20 + p}$

But, here the probability of drawing a red tile = 1/10

$\implies \frac{1}{10} = \frac{20}{20+p} \\\implies 20 + p = 200\\\implies p = 200- 20 = 180$

or, p = 180

Hence, if the number of blue tiles in the bag = 180, then the P Picking out a red tile ) is 1/10.
