This is markdown, thus once again, two equations.
Markdown=Original-New
and
Markdown%=Markdown Amount/Original*100
Markdown=10-3
Markdown=7
Markdown%= 7/10*100
=0.7*100
=70
Thus, the percent decrease/Markdown is 70%.
We know that the probability density function of a variable that is normally distributed is f(x) = 1/(σ√2π) * exp[1/2 (x – µ). Its inflection point is the point where f"(x) = 0.
Taking the first derivative, we get f'(x) = –(x–µ)/(σ³/√2π) exp[–(x–µ)²/(2σ²)] = –(x–µ) f(x)/σ².
The second derivative would be f"(x) = [ –(x–µ) f(x)/σ]' = –f(x)/σ² – (x–µ) f'(x)/σ² = –f(x)/σ² + (x-µ)² f(x)/σ⁴.
Setting this expression equal to zero, we get
–f(x)/σ² + (x-µ)² f(x)/σ⁴ = 0
Multiply both sides by σ⁴/f(x):
–σ² + (x-µ)² = 0
(x-µ)² = σ²
x-µ= + – σ
x = µ +– σ
So the answers are x = µ – σ and x = µ + σ.
Answer:
9, 3
Step-by-step explanation:
To get from 27 to 21, you subtract by 6. To get from 21 to 15, you must also subtract by 6. Therefore, subtracting by 6 is the pattern. In order to get the next number in the sequence, we must subtract 6 from 15.
15 - 6 = 9
The next number is 9. To find the number after 9, we must do the same thing - subtract 6 from 9.
9 - 6 = 3
The 5th number of the sequence is 3.
I hope this helps and please mark me as brainliest!
Answer:
6%
Step-by-step explanation:
There are 10 cards total
P( not pink) = cards not pink/ total = 6 non pink cards /10 = 3/5
We replace the card so we still have 10 cards total with the same color distribution
P( yellow) = cards that are yellow /total = 1/10
Multiply the probabilities
P( not pink, yellow) = 3/5 * 1/10 = 3/50 = 6/100 = 6%
