Answer:
2.275%
Step-by-step explanation:
The first thing to do here is to calculate the z-score
Mathematically;
z-score = (x-mean)/SD
from the question, x = 12,300 hours , mean = 11,500 hours while Standard deviation(SD) = 400 hours
Plugging the values we have;
z-score = (12,300-11,500)/400 = 800/400 = 2
Now, we want to calculate P(z ≤ 2)
This is so because we are calculating within a particular value
To calculate this, we use the z-score table.
Mathematically;
P(z ≤ 2) = 1 - P(z > 2) = 1 - 0.97725 = 0.02275
To percentage = 2.275%
Number lines are used to represent points at regular interval.
The coordinate of point T on the number line is: 46.5
Given that:
The coordinate of X at the midpoint is:
So, we have:
Point T is at 2/3 from X to B.
The coordinate of T is calculated using:
So, we have:
<em>Hence, T is located at 46.5</em>

Pick any two points
(0, 3), (-1,9)
Find slope (y2-y1)/(x2-x1)
(9-3)/(-1-0) = 6/-1 = -6
Y = -6x + b
Plug in a point
3 = 0 + b, b= 3
Final equation: y = -6x + 3
4 · x^4 · x^4 · y
4 x^8 y
In words: four times x to the eighth times y
