Answer:
x=ln(12)/ln(4)-2
Step-by-step explanation:
4^(x+2)=12
x+2=ln(12)/ln(4)
x=ln(12)/ln(4)-2
Answer:
Step-by-step explanation:
given that you look over the songs in a jukebox and determine that you like 14 of the 52 songs
Here each song is independent of the other song
i.e. p = Probability that you like any song =
q = Prob you do not like = 1-0.2692 = 0.7308
a) the probability that you like the next four songs that are played
=
b) the probability that you do not like the next four songs that are played
=
Answer:
0.81859
Step-by-step explanation:
We solve using z score method
The formula for calculating a z-score is is z = (x-μ)/σ,
where
x is the raw score
μ is the population mean
σ is the population standard deviation.
Mean 0.8 pound
Standard deviation 0.25 pound
For x = 0.55 pound
z = 0.55 - 0.8/0.25
= -1
Probability -value from Z-Table:
P(x = 0.55) = 0.15866
For x = 1.3 pounds
Z = 1.3 = 0.8/0.25
= 2
Probability value from Z-Table:
P(x = 1.3) = 0.97725
The probability that a randomly selected zucchini will weigh between 0.55 pound and 1.3 pounds is
P(x = 1.3) - P(x = 0.8)
0.97725 - 0.15866
0.81859.
Let's see....
Let's first simplify step-by-step.
2/4 - 8z + 2(2-5)
= 1/2 + - 8z + -6
Combine Like Terms:
= 1/2 + -6
= (- 8z) + (1/2 + -6)
=(- 8z) + (1/2 + -6)
= - 8z + -11/2
___________________________________
Our answer:
= - 8z + -11/2
Hope This Helps!!!!!!!!
