Find a average daily rainfall for a 30 days month if the total rainfall during that period was 16.8 inches.
max2010maxim [7]

Average = 0.56 inches

Solution:

Given data: Total rainfall = 16.8 inches

Total number of days for a month = 30

To find the average of the rainfall.

Formula for average:

\text {Average}=\frac{\text {Sum of the observations}}{\text {Total number of observations}}

\text {Average}=\frac{16.8}{30}

            = 0.56 inches

Average = 0.56 inches

Hence, average of daily rainfall is 0.56 inches.

If D is the midpoint of the segment AC and C is the midpoint of segment DB , what is the length of the segment AB , if AC = 3 cm
Juliette [100K]
<span>A midpoint divides a line or a segment into two equal parts. If D is the midpoint of the segment AC and C is the midpoint of segment DB, what is the length of the segment AB, if AC = 3 cm.</span>

 

If D is the midpoint of AC, then AD=DC

If C is the midpoint of DB, then DC=CB

If AC=3cm. then then DC-3/2=1.5

If DC=1.5 then CB is 1.5 also

AB=AC+CB

AB=3+1.5

AB=4.5
