Please I need help with this Question
frutty [35]

Answer:

The data set with the greater range is the Girls

The greater median is the Girls at 110

Step-by-step explanation:

The range is the difference between the largest and smallest values.

As the largest value for the boys is 120 and the smallest is 60, the range would be 60

As the largest value for the girls is 150 and the smallest is 70, the range would be 80.

This means that the Girls have the greater range

The median is the number in the middle when the data is in ascending order.

As we have an even number, we will have to find the middle value between 5 and 6. To do this, we can add them together and divide them by 2.

The 5th boy in ascending order is 90 and the 6th boy is 90.

(90+90)/2=90

The 5th 5irl is 100 and the 6th girl is 120

(100+120)/2=110

This means that the median is greater for the Girls.

In an election the successful candidate registered 5,77,500 votes and his nearest rival secured 3,48,700 votes by what margin di
Sav [38]

Answer:

the successful candidate won the election with a 24% margin.

Step-by-step explanation:

With the infomation provided, first you need to find the total amount of votes by adding the number of votes that the successful candidate registered plus the number of votes that his nearest rival secured:

577,500+ 348,700=926,200

Next, you need to find the percentage of votes that the successful candidate registered and that the nearest rival secured by dividing the number of votes by the total amount of votes and multiplying the result for 100:

577,500/925,200=0.62*100=62%

348,700/926,200=38%

Now, you need to find the difference between both percentages to get the margin:

62%-38%=24%

According to this, the answer is that the successful candidate won the election with a 24% margin.
