Eva payrolls for on a number cube and the number of cubes roll 24 times then what is a reasonable prediction for the number of s

Allushta [10]

Answer:

The reasonable prediction for successful rolls is 4.

Step-by-step explanation:

Assuming the rolling cube is a fair 6 sided cube, so the probability of success of one roll is given as

$P(Success)=\dfrac{Number\ of\ successful\ events}{Number\ of\ total\ events}$

$P(Success)=\dfrac{1}{6}$

The total success is given as

$P(Total\ Success)=P(Success)\times Number\ of\ events$

For 24 rolls it is given as

$P(Total\ Success)=P(Success)\times Number\ of\ events\\P(Total\ Success)=\dfrac{1}{6}\times 24\\P(Total\ Success)=4$

So the reasonable prediction for successful rolls is 4.

<h2>Length of track is 168 meter</h2>

Let l be the length of track.

Running speed = 4 m/s

Jogging speed = 2 m/s

Total time taken = 2 minutes 6 seconds. = 126 seconds

That is

$\frac{l}{4}+\frac{l}{2}=126\\\\0.75l=126\\\\l=168m$

Length of track is 168 meter

Given : 5x + 7.5 = 15.

To find : Which bar diagram represents the equation.

Solution : We have given 5x + 7.5 = 15

In the equation we can see sum of 5x and 7.5 is 15 .

By the bar graph combination box of 5x and box of 7.5 is equal to the box of 15.

Then Third bar graph represent the equation .

Two pink boxes of 5x and 7.5 and one blue box of 15.

Therefore, Third bar graph.
