Answer: Area of shaded region is 1.72 ft²
Step-by-step explanation:
Area of shaded region = area of the rectangle - area of the semi circle.
The formula for determining the area of a circle is expressed as
Area = πr²
Where
r represents the radius of the circle.
π is a constant whose value is 3.14
Since we are dealing with a semi circle, then
Area of semi circle = 1/2 × πr²
From the diagram,
Diameter = 4 ft
Radius = diameter/2 = 4/2
Radius = 2 ft
Area = 1/2 × 3.14 × 2² = 6.28 ft²
Considering the triangle,
Length = diameter = 4 ft
Width = radius = 2 ft
Area of rectangle = 4 × 2 = 8 ft²
Area of shaded region
= 8 - 6.28 = 1.72 ft²
Answer:
We are given the below frequency table:
Time (sec) Frequency
60 to 119 8
120 to 179 25
180 to 239 14
240 to 299 2
300 to 359 6
Total 55
Therefore, there are 55 individuals included in the summary.

the value of P(B|A)P(B∣A), rounding to the nearest thousandth
Step-by-step explanation:
Let assume that
Cost of 1 burger = $ x
Cost of 1 doughnuts = $ y
According to statement, 9 burgers and 1 doughnut cost $ 31.30
According to statement again, 3 doughnuts and 6 burgers cost $ 26.70
On substituting the value of y from equation (1), we get
So,
Cost of 2 burgers = 3.2 × 2 = <u>$ 6.4</u>
