$7 - 4w = 10w \\ \\ 7 = 10w + 4w \\ \\ 7 = 14w \\ \\ \frac{7}{14} = w \\ \\ \frac{1}{2} = w \\ \\ w = \frac{1}{2} \\ \\$

The final result is: w = 1/2 or w = 0.5.

Order these list of decimals from smallest to largest -8.91 4.56 -2.8 0.62

vodka [1.7K]

Answer: -8.91, -2.8, 0.62, 4.56

Step-by-step explanation:

The negative numbers are smaller than the positive ones. The larger number behind the negative sign is smaller. Therefore, -8.91 is smaller than -2.8 so -8.91 is first and -2.8 is second. The last two numbers are positive so you compare them. 0.62 is smaller than 4.56 so the list of decimals from smallest to largest is -8.91, -2.8, 0.62, 4.56.

Hope this helps!

stepladder [879]

Given:

The data set is

21, 16, 30, 15, 16, 18, 10, 24, 26, 20, 19, 24, 24, 25, 23

10, 15, 16, 16, 18, 19, 20, 21, 23, 24, 24, 24, 25, 26, 30

To find:

The range, average and median for the given data set.

Solution:

Arrange the data set in ascending order.

10, 15, 16, 16, 18, 19, 20, 21, 23, 24, 24, 24, 25, 26, 30

(1)

Range = Maximum value - Minimum value

= 30 - 10

= 20

Therefore, the range of the given data set is 20. All the options are incorrect.

(2)

$Average=\dfrac{\text{Sum of all observations}}{\text{Number of observations}}$

$Average=\dfrac{311}{15}$

$Average\approx 20.73$

Therefore, the average score is about 20.73. All the options are incorrect.

(3)

Number of observations = 15, which is odd.

$Median=\dfrac{n+1}{2}\text{th term}$

$Median=\dfrac{15+1}{2}\text{th term}$

$Median=\dfrac{16}{2}\text{th term}$

$Median=8\text{th term}$

In the arranged data set 8th term is 21.

$Median=21$

Therefore, the correct option is b.
