2. a beverage company conducts a survey in the lobby of a health club to determine people's favorite beverage.
This question is biased, because certain drinks would be ruled out for being "unhealthy", such as soda, beer, etc. This means that healthier drinks, such as mineral water, electrolyte water, etc, would get more votes.
hope this helps
.053 is the answer to your question.
Because it accurately depicts the distribution of values for many natural occurrences, it is the most significant probability distribution in statistics.
The most significant probability distribution in statistics for independent, random variables is the normal distribution, sometimes referred to as the Gaussian distribution. In statistical reports, its well-known bell-shaped curve is generally recognized.
The majority of the observations are centered around the middle peak of the normal distribution, which is a continuous probability distribution that is symmetrical around its mean. The probabilities for values that are farther from the mean taper off equally in both directions. Extreme values in the distribution's two tails are likewise rare. Not all symmetrical distributions are normal, even though the normal distribution is symmetrical. The Student's t, Cauchy, and logistic distributions, for instance, are all symmetric.
The normal distribution defines how a variable's values are distributed, just like any probability distribution does. Because it accurately depicts the distribution of values for many natural occurrences, it is the most significant probability distribution in statistics. Normal distributions are widely used to describe characteristics that are the sum of numerous distinct processes. For instance, the normal distribution is observed for heights, blood pressure, measurement error, and IQ scores.

Answer:
D) Consistent and Independent
Step-by-step explanation:
The system of equations,
and
is consistent and independent if 
The system is consistent and dependent if 
The system is inconsistent if 
Now, in the given system
4x - y + 3 = 0 and
2x - y - 4 = 0
So, 
Hence, the given system is consistent and independent.
Answer:
Total cars=30 and
motorcycles =75
Step-by-step explanation:
Total Motorcycles= 75
wheels for motorcycles =75*2=150
total wheels= 270
cars have four wheels so 270-150=120
120/4=30
Total cars=30 and motorcycles =75
