Answer:
s =$10, l = 15, together they are $25
Step-by-step explanation:
Alberto: 1s + 1l = 25
Kali: 3s + 9l = 165
Multiply Alberto x 3: 3s + 3l = 75
Subtract from Kali:
3s + 9l = 165
- 3s + 3l = 75
6l = 90
l = 15, Large = $15.
Substitute into one of the equations: s + l = 25
s + 15 = 25
s = 10
Answer:
(f-g)(x) = x^3 -6x^2 +6x -10
Step-by-step explanation:
(f-g)(x) = f(x) - g(x) = (x^3-2x^2+12x-6) - (4x^2+6x+4)
= x^3 + x^2·(-2-4) +x·(12 -6) + (-6-4)
= x^3 -6x^2 +6x -10
Guessing you want to simplify each,
first one goes to just x
second goes to 4x
third goes to 18x-15
Answer:
97.73%
Step-by-step explanation:
Mean (μ) = 170
Standard deviation (σ) = 5
Assuming a normal distribution, for any observed value, X, the z-score is determined by:
For X = 180:
A z-score of 2 corresponds to the 97.73-th percentile of a normal distribution.
Therefore, the percentage of data that is less than 180 is 97.73%.
