Summing all the frequencies, we deduce the total number of trials:

4+8+36+20+12=80

Knowing how many trials have been done, we deduce the probability of each outcome by dividing its frequency and the number of trials:

P(0)=\dfrac{4}{80}=\dfrac{1}{20},\quad P(1)=\dfrac{8}{80}=\dfrac{1}{10},\ldots

Convert these fractions to numbers, and drag each slider where it is supposed to be.

Fox example, we have

P(0)=\dfrac{1}{20} = 0.05

So, you'll have to drag the first slider up to 0.05, and so on.

A tennis player has won 24 out of 36 matches. His sponsor says that he must win 70% of his total number of matches to qualify fo
pashok25 [27]

Answer:

He must win 11 more matches to qualify for the bonus.

Step-by-step explanation:

24/36 * 100 = 67% (to the nearest %) - This is the current percentage of what the Tennis player has won.

If we add 14 more matches on to the 36 the player has already played, we know that the Tennis player plays 50 matches in total.

Let's say the Tennis player was playing 100 matches, they would need to win 70 or more to qualify for the bonus. Because the player is playing half this amount of matches, we half the amount of games they have to win...

35/50 games or more must be won to qualify for the bonus. The Tennis player has already won 24 matches, so must win 11 more matches to qualify for the bonus.

Hope that helps!

natita [175]

Answer:

They are skew lines.

Step-by-step explanation:

Which statement is true about lines a and b?

They are parallel lines.

They are perpendicular lines.

They are skew lines.

They will intersect.

As they both are in different directions they are skew lines .

Skew lines are not parallel neither they .They are also not co planar i.e they lie in different planes.

We have two plane Q and R . We have two line a and b on the different planes Q and R. Both planes are parallel but the lines a and b are in different directions. Therefore they are skew lines . They do not intersect and are also not parallel neither co planar.
