There were 60 runners to start a race. In the first half of the race, 1/3 of them dropped out. In the second half of the race, 4/5 of the remaining runners dropped out. How many runners finished the race?

Answers

Answer:

08 runners finished the race.

Step-by-step explanation:

Given that:

Number of runners at the race = 60

Number of runners dropped in first half = 1/3 of 60

Number of runners dropped in first half = [tex]\frac{1}{3}*60 = 20[/tex]

Remaining runners = 60 - 20 = 40

Number of runners dropped in second half = 4/5 of 40

Number of runners dropped = [tex]\frac{4}{5}*40 = 32[/tex]

Runners left = 40 - 32 = 08

Hence,

08 runners finished the race.

Suppose you have a population in which 60% of the people approve of gambling. Is the value 0.60 a parameter or a statistic

Answers

Answer:0.60 is a parameter .

Step-by-step explanation:

In statistics, a parameter is a number that summarize the data for a whole population.

On the other hand , statistic gives a measure for sample of population.

Given: We have a population in which 60% of the people approve of gambling.

60% = 0.60

Since it is a measure for the population , it is denoted as population parameter.

Hence, 0.60 is a parameter not statistic.

TW = ST

Step-by-step explanation:

Therefore, the third corresponding sides, TW and ST would be congruent to each other.

Thus:

TW = ST

20% of Aussies have blue eyes. If 4 Aussies in a play group have blue eyes, how many Aussies are in the group?

Answers

Answer:

20

Step-by-step explanation:

Step 1: 4 = 20% × Y

Step 2: 4 = 20/100 × Y

Multiplying both sides by 100 and dividing both sides of the equation by 20 we will arrive at:

Step 3: Y = 4 × 100/20

Step 4:Y = 4 × 100 ÷ 20

Step 5: Y = 20

The percentage is calculated by dividing the required value by the total value and multiplying it by 100.

20% = 4

100% = 20

The total number of people in the group is 100 people.

What is a percentage?

The percentage is calculated by dividing the required value by the total value and multiplying it by 100.

Required percentage value = a

total value = b

Percentage = a/b x 100

Example:

50% = 50/100 = 1/2

25% = 25/100 = 1/4

We have,

Number of Aussies with blue eyes = 4

Percentage of blue eyes in the Aussies = 20%

This can be written as:

20% = 4

Now,

The percentage of the total number of people in the group = 100%

So,

20% = 4

Multiplying 5 on both sides.

5 x 20% = 5 x 4

100% = 20

This means,

The total number of people in the group is 100.

Thus,

The total number of people in the group is 100 people.

Marko's heart beats 72 times per minute during normal activity. It beats 65 times

During a 24-hour period, Marko slept from 10:00 p.m. until 5:00 a.m. and then
exercised from 5:30 a.m. to 7:30 a.m. For the remaining time he had normal

2 times 118=236 times60=14 160

15 times 72=1080 times 60=64 800

26700 plus 14 160 plus 64 800=105,660

brainliest please

Answer:

105,540 beats

Step-by-step explanation:

10:00-5:00 is 7 hours long so

60(minutes)×7=420 minutes

since his heart beats 65 times/min.

420×65=27,300 beats

5:30-7:30 is 2 hours long so

60(minutes)×2=120 minutes

120×118=14,160 beats

7 hours+2 hours=9 hours

24-9=15 hours

60×15=900 minutes

900×72 beats=64,800 beats

Add all heart beats together

27,300+14,160+64,080=105,540
