The ratio of sixth-grade students to fifth-grade students on the team

is 8 : 7.

What are ratio and proportion?

A ratio is a comparison between two similar quantities in simplest form.

Proportions are of two types one is the direct proportion in which if one quantity is increased by a constant k the other quantity will also be increased by the same constant k and vice versa.

In the case of inverse proportion if one quantity is increased by a constant k the quantity will decrease by the same constant k and vice versa.

Given, Last year the girls’ basketball team had 8 fifth-grade students and 7 sixth-grade students which is 8/7.

In the ratio form, it is 8 : 7.

Answer:

The answer is 1 6/8, but in simplest form 1 3/4.

Step-by-step explanation:

Convert 5 3/8 into an improper fraction then convert 3 5/8 into and improper fraction. 5 3/8 will become 43/8 and 3 5/8 will be 29/8.

So, 43 - 29 = 14, which gives us 14/8. Turn 14/8 into a mixed number, giving you 1 6/8, but since it says to simplest form, 1 6/8 will be 1 3/4. This is our answer in simplest form.

Answer:

Hence experimental probability that all 3 coins show the same result when he tossed it for 50 times and 8 of those are of success is 0.04

Step-by-step explanation:

Given:

3 coins are tossed at same time

No of trails are 50 and

success for trails are 8.

To Find:

Experimental probability for 3 coins that getting all heads or all tails.

Solution:

Now

When only 3 coins are tossed probability that getting all heads is  as follows:

Calculating the sample space of the event

Event is 3 coins are tossed at a time

So Sample space S={HHH,HHT,HTH,HTT,THH,THT,TTH,TTT}

n(S)=8

No of trails getting all heads is 1

So P(getting all heads )=1/8

Same of tail  i.e. 1/8

Adding both will be required probability for getting all heads or tails

here or ' operator so Addition

1/8+1/8=2/8

=1/4

1/4 is probability that the all heads or all tails when coins is tossed one time

but here it is about 50 times and probability if successs trails are 8

Hence

Now

Probability of success P=8/50=0.16

Probability  of getting all heads and all tails in 50 trails of which 8 are only success

Hence required Probability =Probability of success *Probability of getting all heads or tails

=0.16*(1/4)

=0.16*0.25

=0.04

Hence experimental probability that all 3 coins show the same result when he tossed it for 50 times and 8 of those are of success is 0.04
