Answer:
$24.00
Step-by-step explanation:
x = per month
y = per song
t = total
Equation:
t = 14x + 0.5y
t = 14(1) + 0.5(20)
t = 14 + 10
t = 24
Answer:
(x + 1)(x - 1)(x² + 9)
Step-by-step explanation:
Factorise the following:
x⁴ + 8x² - 9
The factors of -9 that sum to 8 are 9 and -1.
So,
x²(x² + 9) - 1(x² + 9)
(x² - 1)(x² + 9)
x² - 1 = x² - 1²:
(x² - 1²)(x² + 9)
Factor the difference of two squares.
x² - 1² = (x + 1)(x - 1):
(x + 1)(x - 1)(x² + 9)

Answer:
B. n=36, p=0.98, x=12
Step-by-step explanation:
98% of bottles have the correct amount.
The probability is equal to 0.98
That is p = 0.98
A bottle of water is supposed to have 12 ounces.
That is the expected value is 12
X = 12
36 bottles has all bottles properly filled
The possible sample space is 36
N = 36
