Answer:
0.90
Step-by-step explanation:
full price discounted total
month 1 49 1 50
month 2 120 5 125
month 3 101 24 125
total 270 30 300
full price discounted total
month 1 0.98 0.02 1
month 2 0.96 0.04 1
month 3 0.808 0.192 1
total x = 0.9 y = 0.10 1
x = 270 / 300 = 0.90
y = 30 / 300 = 0.10
Let the profit at the first year be X
3x=114000
Solve for x by dividing each side by 3
3x/3=114000/3
X=38,000
So the profit was 38000
Answer:
B. Yes, there are at least 10 people with weak bones and 10 people with strong bones in each group.
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a random variable X, with mean 
and standard deviation 
, a large sample size can be approximated to a normal distribution with mean and standard deviation 
The correct answer is:
B. Yes, there are at least 10 people with weak bones and 10 people with strong bones in each group.
Answer:
-2x³ + x² - 3x - 15
Step-by-step explanation:
Simply combine like terms together:
-5x² - 3x - 7 - 2x³ + 6x² - 8
-2x³ + (-5x² + 6x²) - 3x + (-7 - 8)
-2x³ + x² - 3x + (-7 - 8)
-2x³ + x² - 3x - 15
Equation: 5x² - 3x - 14
= 5x² - 10x + 7x - 14
= 5x(x - 2) 7(x - 2)
= (5x + 7)(x - 2)
In short, Your Answer would be: Option B
Hope this helps!
