If amount of utility bill is normally distributed with a mean of $105 and a standard deviation of $20. What percentage of your bills would you expect to be between $85 and $125?
Answers
Answer:
68% of your bills between $85 and $125
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
68% of the measures are within 1 standard deviation of the mean.
95% of the measures are within 2 standard deviation of the mean.
99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean = $105
Standard deviation = $20
What percentage of your bills would you expect to be between $85 and $125?
85 = 105 - 20
125 = 105 + 20
Within one standard deviation of the mean, so by the Empirical Rule, 68% of your bills between $85 and $125

Lewis is hiking in a state park when he spots a brightly colored bird in a distant tree. Lewis is 60 feet away from the tree, and the bird is perched on a branch 22 feet above the ground. Lewis is 5 feet tall.
What is the angle of elevation, in degrees, of Lewis' line of sight to the bird?
Answers
Answer:
he is 77 feet away from mr. birdie
Step-by-step explanation:
Quite certain it'd be 15.8 degrees.
Think about it, we're trying to figure out his angle of sight. If his eyes are 5 feet above ground, and the bird is 22 feet off the ground, there's really only a 17 ft height difference between the two. After doing the formulas and all, we can see that the angle of his vision is approximately 15.8.

Answer:
x = 3.6
Step-by-step explanation:
The angle bisector divides the segments proportionally. This means they satisfy ...
bottom segment / side segment = x/6 = (6-x)/4
Multiplying by 12 gives ...
2x = 3(6 -x)
2x = 18 -3x . . . . . eliminate parentheses
5x = 18 . . . . . . . . add 3x
x = 3.6 . . . . . . . . . divide by 5

Alternate solution
I like to try to work these mentally. The total of side lengths is 10, so the total base length (6) is 6/10 = 0.6 times that. Then x will be 0.6 times the left side length: 0.6·6 = 3.6 = x.

C) 1/3, 2, √7
Step-by-step explanation:
√7= 2.6
1/3= 0.3
2=2
1/3, 2, √7
C.
*if using a calculator*
1/3= .333
square root 7 equals about 2.646
therefore, we know .333 (1/3) is the smallest out of the numbers and 2.646 (sqr root 7) is the biggest.
*if you cannot use a calculator*
We know 1/3 is less than 1 because 3/3 would equal 1 and we only have 1/3.
We don’t know the square root of 7, however we know that it has to be between 2 and 3 because the square root of 4 is 2 and the square root of 9 is 3. 7 is between those two numbers, so therefore we know that the square root would have to be between 2 and 3.
Knowing that, we could figure out that since 1/3 is less than 1 it would be the smallest. Since the sqr root of 7 is between 2 and 3, it would be bigger than 2 and the biggest out of the 3.
Conclusion:
The order is 1/3, 2, sqr root 7
