Please help a girl out I’m honestly extremely slow

First, reorder the numbers so they go from least to greatest. It should look like this:

-11, -9, -6, 0, 2, 18, x, 20, 36, 37, 46, 47, 51.

Mean: 19.25

The mean is the average. To find it, add all numbers together and divide by how many numbers there are.

Median: 19

The median is the center number in the ordered line of numbers. I added a bolded variable (x), so you can see where it is. Because it's between two numbers, add those numbers and divide by 2.

Mode: N/A

There's not a mode. A mode is a repeating number in the sequence.

Range: 62

Range is the difference between the largest and smallest number.

47.)

The range is larger than the highest temperature because the temperature values are both positive and negative. Due to this, the smallest number (-11) becomes positive as the negative sign is distributed to it and adds to the largest number (51).

48.)

Again, mean is the average. Add all values together and divide by the number of values there are.

36 is the final answer! : )

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
