Answer:

mean: 4

median: 5

mode: 5

Step-by-step explanation:

Hi there!

Let's first start with the mean

the mean is the average of all of the numbers; we add up how many hours each week each student spent playing video games and then divide it by how many people responded (9)

(0+5+7+5+3+0+9+5+2)/9

add all of the numbers on top

36/9

divide

4

the mean is 4

now find the median, or the value that separates the upper half from the lower half of the data (it's the "center" value).

first, list the numbers in order from least to greatest

0,0,2,3,5,5,5,7,9

now get rid of the largest number and the smallest number  (0 and 9)

the set is now:

0,2,3,5,5,5,7

now get rid of the largest and smallest number in the new set (0 and 2)

the set becomes:

2,3,5,5,5

get rid of the largest and smallest number in the new set (2 and 5)

3,5,5

get rid of the largest and smallest number in the new set  (3 and 5)

5

the median is therefore 5

the mode is the number that occurs most frequently in the data set

here's our list again of all of the numbers from least to greatest:

0,0,2,3,5,5,5,7,9

we can count how many times each number appears to find the mode

0: 2 times

2: 1 time

3: 1 time

5: 3 times

7: 1 time

9: 1 time

since 5 appeared the most times, then the mode is 5

hope this helps!

Solve 4\5x-4\10=2\20
Soloha48 [4]
4/5x - 4/10 = 2/20...multiply everything by common denominator 20
16x - 8 = 2
16x = 2 + 8
16x = 10
x = 10/16 which reduces to 5/8 <=

Two trains start from Fort Worth traveling at the same speed. The trip for Train W takes 20 hours, while the trip for Train Z ta
MrMuchimi

Answer:

The equation that best models this situation is :

b. \frac{x}{20}=\frac{x+400}{25}

Distance traveled by Train W = 1600 miles

Distance traveled by Train Z = 2,000 miles

Step-by-step explanation:

Given:

Time taken for Train W to complete a trip = 20 hours

Time taken for Train Z to complete a trip = 25 hours

The city Train Z is traveling to is 400 miles farther away than the city Train W is traveling to.

both trains have same speeds and start from same location.

To find the distance in total each train travels.

Solution:

<em>Let length of the trip of Train W be </em>= x miles

Speed of Train W can be given as :

⇒ \frac{Distance}{Time}

⇒ \frac{x}{20}\ miles/h

<em>So, the length of the trip of Train Z will be</em> = (x+400) miles

Speed of Train Z can be given as :

⇒ \frac{Distance}{Time}

⇒ \frac{x+400}{25}\ miles/h

Since the speeds are same, so the equation to find x can be given as:

⇒ \frac{x}{20}=\frac{x+400}{25}

Solving for x

Multiplying both sides by 100 to remove fractions.

⇒ 100\times \frac{x}{20}=100\times \frac{x+400}{25}

⇒ 5x=4(x+400)

Using distribution.

⇒ 5x=4x+1600

Subtracting both sides by 4x

⇒ 5x-4x=4x-4x+1600

⇒ x=1600

Thus, Distance traveled by Train W = 1600 miles

Distance traveled by Train Z = 1600+400 = 2,000 miles
