Answer:

40%

Step-by-step explanation:

6 apples out of 15 fruits = $\frac{6}{15}$

$\frac{6}{15}$ is equivalent to $\frac{2}{5}$

$\frac{2}{5}$ is equivalent to 40%

<em>So your answer is 40%</em>

N a game show, a contestant randomly draws a chip from a bag and replaces it. The theoretical probability of drawing a winning c

erica [24]

Answer:

I would expect 6 contestants to draw a winning chip each.

Step-by-step explanation:

Theoretical probability is basically = Number of successful outcomes/Number of possible outcomes.

Since the theoretical probability of drawing a winning chip is 3(winning chips)/10(total chips), if there are 9 winning chips in the bag, we need to first calculate the total number of chips in the bag using the principle of proportion.

Let's call the total number of chips in the bag, "x".

3/10 = 9/x

Cross multiplying:

3x = 90

x = 90/3

x = 30 chips

There is a total of 30 chips in the bag.

Now, if there are 9 winning chips in a bag that contains 30 chips altogether and 30 contestants are to draw one chip each from the bag, I would expect 9 contestants out of the 30 contestants that drew chips from the bag to draw winning chips.

Then if each of the 20 contestants are to draw a single chip from the bag of 30 chips, then the number of contestants that I would expect to draw a winning chip is:

30 contestants----------9 winning chips

20 contestants----------- ? winning chips

20/30 × 9

= 180/30

= 6 winning chips to be drawn by 6 different contestants.

Therefore the number of contestants that I would expect to draw a winning chip from the bag is 6

Determine the zeros of r=2sin5theta

vazorg [7]

Answer:

$\theta=\frac{n\pi}{5}$

Step-by-step explanation:

You have the following function:

$r=2sin5\theta$ (1)

In order to find the zeros of the function you equal to zero the equation (1), and then you solve for θ:

$2sin5\theta=0\\\\sin5\theta=0\\\\5\theta=sin^{-1}(0)=n\pi;\ \ \ \ n=0,1,2,3,..\\\\\theta=\frac{n\pi}{5}$

Then, there are infinite zeros for the function of the equation (1), because n has infinite positive integers values.
