To find this answer, all we have to do is identify the least common multiple of 6 and 20
the lowest number that both of these numbers can go into evenly is 60
so each 60th visitor gets both
Answer:
D) 11/12
Step-by-step explanation:
From 1 to 12, 6 numbers are odd (1, 3, 5, 7, 9, and 11).
7 numbers are non-prime (1, 4, 6, 8, 9, 10, and 12).
2 numbers are both odd and non-prime (1 and 9).
Therefore, the probability is:
(6 + 7 − 2) / 12 = 11/12
Answer:
option (d) 16.6 and 21.4
Step-by-step explanation:
Data provided in the question:
The mean life for a particular use before they failed = 19.0 hours
The distribution of the lives approximated a normal distribution
The standard deviation of the distribution = 1.2 hours
To find:
The values between which 95.44 percent of the batteries failed
Now,
In Normal distribution, the approximately 95% ( ≈ 95.44% of all values ) falls within 2 standard deviations of the mean
Therefore,
Upper limit = Mean + 2 × standard deviation
⇒ Upper limit = 19.0 + 2 × 1.2 = 21.4
Lower limit = Mean - 2 × standard deviation
⇒ Lower limit = 19 - 2 × 1.2 = 16.6
Hence,
the answer is option (d) 16.6 and 21.4
The probability is 0.337.
The probability that more than 3 prefer brand c is the same as finding the probability that 4 or 5 prefer brand c. Using a binomial distribution,
Answer:
-3
Step-by-step explanation:
Pick two points on the graph, lets go with (0, 4) and (1, 1)
y = mx + b
m is the slope and to figure it out use below formula
m = (y₂ - y₁) / (x₂ - x₁)
= (1 - 4) / (1 - 0)
= -3 / 1
= -3
