Of the 17 students in a programming class, 6 own 1 computer, 3 own 2 computers, 3 own 3 computers, 2 own 4 computers, and 3 own

AlexFokin [52]

The median number of computers owned by the 17 students is 2.

<h3>What is median in statistics?</h3>

A dataset's median represents the midpoint; half of the data points are smaller and half are greater than the median.

Identifying the median: The data points should be arranged from smallest to largest. The median is the middle data point in the list if the number of data points is odd.

The total number of students are 17.

The data can be arranged in the following table

number of students number of computers

6 1

3 2

3 3

2 4

3 5

Arrange the given frequencies in the increasing order-

1 1 1 1 1 1 2 2 2 3 3 3 4 4 5 5 5

The middle term of the arrange frequencies is 17/2 = 8.5

Median = (8 term + 9 term)/2

= (2 + 2)/2

= 2

Therefore, the median number of computers owned by the 17 students is 2.

In your class seven students do not receive a weekly allowance, Five students receive three dollars, Seven students receive five

olya-2409 [2.1K]

Answer:

$\large \boxed{\text{\$3.50}}$

Step-by-step explanation:

The mean is the sum of the allowances divided by the number of students.

$\text{Mean}= \dfrac{7(0) + 5(3) + 7(5) + 3(6) + 2(8)}{24}= \dfrac{0 + 15 + 35 + 18 + 16}{24} = \mathbf{3.50}\\\text{The mean weekly allowance is $\large \boxed{\textbf{\$3.50}}$}$

the Royal fruit company produces two types of fruit drinks. The first type is 20% pure fruit juice, and the second type is a 45%

AlexFokin [52]

We know that 20% of the first type of juice is pure fruit juice and 45% of second type of juice is pure fruit juice.

Now we have to make 30 pints of a mixture that is 35% pure.

Let x be the number of pints of first type of juice and y be the number of pints of second type of juice.

So, $x+y=30$ (Equation 1)

Since, 20% of x + 45% of y = 35.3% of 30

$\frac{x}{5}+\frac{9y}{20}=10.5$ (Equation 2)

Solving equations 1 and 2,

we get y=18 and x=12.

So, 12 pints of first type of juice and 18 pints of second type of juice are used.

Michelle rode her bicycle from her house to school at an average speed of 8 miles per hour. Later that day, she rode from school

Crazy boy [7]

9514 1404 393

Answer:

9.6 miles

Step-by-step explanation:

Let x represent the round trip distance. Then Michelle's time was ...

t = distance/speed

1 = (x/2)/8 +(x/2)/12 = x(1/16 +1/24) = x(3/48 +2/48) = x(5/48)

48/5 = x = 9.6

The round trip is 9.6 miles.
