The frequency table shows the results of tossing a ball 24 times into four colored sections on a carnival game. Based on the dat
Zanzabum

Answer:

See the explanation

Step-by-step explanation:

Ball is tossed 24 times

So the total number of outcomes (tosses) = N = 24

The ball lands in Blue section 3 times out of 24 tosses. So it becomes 3/24

The ball lands in Green section 5 times out of 24 tosses. So it becomes 5/24

The ball lands in Red section 12 times out of 24 tosses. So it becomes 12/24

The ball lands in Yellow section 4 times out of 24 tosses. So it becomes 4/24

Now we have to find how many times will the ball most likely land in the yellow section when it’s tossed 200 times. So the total number of outcomes here is N = 200. The favorable outcome here is that the ball lands in Yellow section. So we use the frequency table above for yellow section:

Yellow / Total tosses

4/24 = x/200

4*200 = 24x

800 = 24 x

24 x = 800

x = 800 / 24

x = 33.3

So ball most likely land in the yellow section 33 times when it’s tossed 200 times So it becomes 33/200 = 0.165 or 10.65% probability that ball will land in yellow section.

What is the point-slope equation of a line with slope -5 that contains the point (6, 3)?
OLEGan [10]
The answer would be D. because the point-slope formula is y-y1=m(x-x1). Since both of the numbers in the point are positive the equation will be the same. You will just substitute the numbers into the equation making it answer D.
