Answer:
- 52.5 in²
- 52.5 in²
- 76.97 in²
- total: 181.97 in²
Step-by-step explanation:
1, 2. The area of each triangle is given by the formula ...
A = (1/2)bh . . . . . for base b and height h
The area of the given triangle is ...
A = (1/2)(7 in)(15 in) = 105/2 in² = 52.5 in²
Triangles 1 and 2 have the same dimensions, so have the same area.
Figure 1 area: 52.5 in²
Figure 2 area: 52.5 in²
__
3. The area of the semicircle is given by the formula ...
A = (1/2)πr² . . . . for a semicircle of radius r
This semicircle has a radius of 7 in, so an area of ...
A = (1/2)(3.1416)(7 in)² ≈ 76.97 in²
Figure 3 area: 76.97 in²
__
The total area is the sum of these:
52.5 in² + 52.5 in² +76.97 in² = 181.97 in²
Composite Figure area: 181.97 in²
_____
<em>Comment on decimal digits</em>
We cannot tell your rounding requirements. Here, we have rounded to the nearest hundredth. If you use the value 3.14 for pi, then your areas for the semicircle and composite figure will end in .93, not .97.
Answer:
0.0014 is the required probability.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 180000 per day
Standard Deviation, σ = 15000 per day
We are given that the distribution of number of viewers is a bell shaped distribution that is a normal distribution.
Formula:
P(number of viewers is more than 1000000 in a week)
Calculation the value from standard normal z table, we have,
0.0014 is the probability that the number of viewers is more than 1000000 in a week.
Answer:
95 m
Step-by-step explanation:
you can split the shape into three pieces so it is 4x5, 4x5, and 11x5. Add the products for the area which is 95 m
