Answer:
I Know the answer because I am in k12 too.
The answer is 37.5%
Step-by-step explanation:
$80 - $50 = $30
$30 * 100 / $ 80 = 37.5%
answer: 37.5% of decrease.
The slope is -4 and the y-intercept is -12.
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%
