Answer:
21+3x
Step-by-step explanation:
multiply the 3 by everything inside the parentheses
Answer: w+1.3 = 2.7
Reason:
The smaller pieces (w and 1.3) combine to form the larger piece (2.7)
To find w, subtract 1.3 from both sides to get 1.4
1.4+1.3 = 2.7

Answer:
- 113.0 cm²
- 2464.0 in²
- 95.0 ft²
Step-by-step explanation:
1. The area of a circle is given by the formula ...
A = πr² . . . . . where r is the radius
The radius is shown as 6 cm, so the area is ...
A = (3.14)(6 cm)² = 113.0 cm²
__
2. The radius is shown as 28 in. We note that this is a number divisible by 7, so we choose 22/7 for π.
A = (22/7)(28 in)² = 2464 in² . . . . see comment
__
3. The radius is half the diameter, so is 11/2 = 5.5 ft. Then the area is ...
A = (3.14)(5.5 ft)² = 95.0 ft²
_____
<em>Additional comment</em>
If you use a more exact value of π for problem 2, the area is 2463.0 in². If you use 3.14 as the value of π, the area rounds to 2461.8 in². For these values of pi (3.14 or 22/7), the answer is only good to about 3 significant digits. 2464 has more significant digits, so digits beyond the first 3 may be in error.
Answer:
probability of Number of earth quakes in a fixed interval of time is to be determined at a mean rate of 1.2 times once every 22 years.
Step-by-step explanation:
Poisson probability distribution is used to determine probability of an event in a fixed interval of time and space given that the event occurs with known mean rate and independently of time since its last occurance.
In this scenario,
Mean is 1.2 times once every 22 years.
probability of number of earth quakes in any fixed interval of time is to be determined
occurance of event that is number of earth quake in a fixed interval is independent variable.
