The area of the given figure is 38 square units
<h3>Area of a trapezoid</h3>
The area of the given trapezoid is expressed as:
A = 0.5(a+b)h
where
a and b are the sides
h is the height
Substitute
A = 0.5(9+10) * 4
A = 19 * 2
A = 38 square units
Hence the area of the given figure is 38 square units

Answer:
s_5=8404
Step-by-step explanation:
This is a geometric series so we can use the formula
S_5=2500-2500*.8^5/1-.8
s_5=2500-2500*.32/.2
s_5=2500-819.2/.2
s_5=1680.8/.2
s_5=8404

Answer:
198 and 612
Step-by-step explanation:
We are given that the scores are normally distributed.
The mean of the data is 405.
The standard deviation of this data is 69.
Empirical rule states that for a normally distributed data that
- about 68% data lies between
that is one standard deviation from mean.
- about 95% data lies between
that is one standard deviation from mean.
- about 99.7% data lies between
that is one standard deviation from mean.
Thus, 99.7% of data will lie between 
that is it will lie in the range (198,612)
