Answer:
271,403 is rounded to 270,000 because the 1403 before it is less than 5000, 4 and below drop it down, 5 or more bump it up.
Step-by-step explanation:
Answer:
Mean = 3.4
Variance = 1.088
Standard deviation = 1.0431
Step-by-step explanation:
The mean of a binomial distribution with parameters N (the number of trials) and p (the probability of success for each trial) is 
Thus,
The variance of the binomial distribution is 
, where 
is the variance of the binomial distribution, so
The standard deviation 
is the square root of the variance 
so
Answer:
- T'(1, -2)
- U'(1, -1)
- V'(2, -1)
- W'(2,-2)
Step-by-step explanation:
Translation 4 right adds 4 to each x-coordinate.
Translation 4 down subtracts 4 from each y-coordinate.
Doing this arithmetic gives you the results above.
Answer: 45°
Step-by-step explanation:
Diameter= 16m
Radius= 16/2 = 8m
The area of the circle= πr^2
= π8^2
= 64π square metres.
An area of 8π square metres is also 1/8 of the total area, therefore the arc must be 1/8 of the circumference.
The circumference = 2πr = 16π,
This gives us an arc length of 2π metres.
But since we are looking for the the angle.
In degrees: 360/8 = 45°
Answer:
Subtract 60 from the sum of 8e and 20 when e=7
8e +20
8(7) + 20
56+20=76
76-60=16
