Answer:
286.97
Step-by-step explanation:
find the area of the rectangle first
14*15=210
Next
Find the area of a circle
πr^2=a
the radius of the circle is half the height of the rectangle
π*(7*7)=a
a=153.94
Now
Divide the area by two
153.94/2=76.97
Now add the two areas
76.97+210
Answer:
Area of the figure= area of the rectangle+ area of the semicircle
=(15×14)+(1/2)π(7)²=210+77=287 square unit
<u>287 square unit</u> is the right answer.
Remember:--- area of the rectangle
=(length×breadth)
and area of the semicircle=π(radius)²/2

Step-by-step explanation:
<u>Given:</u>
<u>Find z-score:</u>
z = (x - μ)/σ z = (104 - 80)/12 = 2 Percent value corresponding to 2 as per z-table is 0.9772. This is corresponding to 97.72%.
<u>Percentage of students earned more than $104:</u>
The error is that the numbers are not in order from least to greatest.
