Question No 1

The range of rainfall for the highland storms is 44 mm

Question No 2

The range of rainfall for the lowland storms is 30 mm

Step-by-step explanation:

Question 1

What is the range of rainfall for the highland storms?

2 46 8 10 12 14 16 18 20 22 24 26 28 30 32

First we arrange data in ascending order.

2 8 10 12 14 16 18 20 22 24 26 28 30 32 46

Now we have to find range. The formula used is:

In the given data set:

Maximum Value = 46

Minimum Value = 2

Finding range by putting values in the formula:

So, the range of rainfall for the highland storms is 44 mm

Question 2

What is the range of rainfall for the lowland storms?

2 4 6 8 10 12 14 16 18 20 22 24 26 28 30 32

First we arrange data in ascending order.

The data is already arranged in ascending order

Now we have to find range. The formula used is:

In the given data set:

Maximum Value = 32

Minimum Value = 2

Finding range by putting values in the formula:

So, the range of rainfall for the lowland storms is 30 mm

john got lost so he didn't know what to do and it was crazy because he didn't except it

step-by-step explanation:

123123 step byt step

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = = -

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, - 8 ), then

- 8 = - + c ⇒ c = -

y = - x - ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form
