X is 2 because 96•45 is 2.1
Answer:
what
Step-by-step explanation:
Answer:
f(x) = 10n
Step-by-step explanation:
If met with questions like these, the term "for each" means to multiply. simply write an equation that multiplies n and 10. Also "f(x)" can be substituted for "y" if that is what your instructor taught you.
Answer: -7
Step-by-step explanation:
To find f(-8) look at the f function. Find the y value when x = -8
To find g(4) look at the g function. Find the y value when x = 3
Plug these values into the equation
-1 f(-8) - 4 f(4)
-1 (-5) - 4 (3)
5 - 12 = -7
Answer:
0.7477
Step-by-step explanation:
The mean(X) = 25,000 hrs
Standard deviation (σ) = 1500 hrs
The probability that the light bulb lasts more than 24,000hrs is Pr (X˃24,000)
Using Z-scores, Z= (X- μ)/σ
For X = 24,000
Z = (24,000 – 25,000)/1500
Z = -1000/1500
Z = -0.667
From the normal distribution table, Z= 0.667 = 0.2477
Φ(Z) = 0.2477
Recall that if Z is negative,
Pr (X˃a) = 0.5 + Φ(Z)
Pr (X˃24,000) = 0.5 + 0.2477
= 0.7477
