Answer: a) 6
<u>Step-by-step explanation:</u>
The mean is 375 which has a z-score of 0.
The standard deviation is 24 so:
- z-score of 1 is: 375 + 24 = 399
- z-score of 2 is: 399 + 24 = 423
- z-score of 3 is: 423 + 24 = 477
A z-score of 3 is 99.85% from the left <em>(or 1 - 99.85% from the right = 0.15%)</em>
Since we are looking for the "more than" a z-score of 3, it is 0.15% of the total.

Answer:
(x, y) = (5, 2)
Step-by-step explanation:
<u>Given</u>:
LP = x
MP = 2y+3
NP = y+3
KP = 3x -8
KP = MP, LP = NP
<u>Find</u>:
x, y
<u>Solution</u>:
The given relations between the segment lengths let us write two equations:
KP = MP
3x -8 = 2y +3 ⇒ 3x -2y -11 = 0 [eq1]
LP = NP
x = y +3 ⇒ x -y -3 = 0 [eq2]
__
Subtracting 3 times [eq2] from [eq1] gives ...
(3x -2y -11) -3(x -y -3) = 0
y -2 = 0 . . . . . . . . simplify
y = 2 . . . . . . . . . . add 2
Substituting this value into [eq2] gives ...
x = 2 + 3 = 5
The values of x and y are ...
x = 5, y = 2

Answer:
Each person would have to contribute to contribute $385 to pay a 1.5 deficit.
Step-by-step explanation:
To determine:
How much would each person have to contribute to pay a 1.5 deficit if United States facing a budget deficit of 1.5 billion and 3.9 million population?
Fetching Information and Solution Steps:
- United States facing a budget deficit of 1.5 billion
- Population = 3.9 million
We have to determine how much would each person have to contribute to pay a 1.5 deficit.
Just dividing 1500 millions (1.5 billion) by 3.9 million as:
which is rounded to $385.
Therefore, each person would have to contribute to contribute $385 to pay a 1.5 deficit.
