Answer:
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or
In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin
In this problem we have
Substitute the values and solve for k
therefore
the equation of the line is equal to
The empirical rule says that approximately 68% of any normal distributed data set lies within one standard deviation of the mean.
The same rule states that about 95% lies within two standard deviations of the mean. Using this rule, and the fact that any normal distribution is symmetric about its mean, you have
Answer:
Letter B matches the probability.
Step-by-step explanation:
Lucy throws a fair six sided dice.
Probability of the dice landing on a number between 1 and 6 =
=
On a number line fraction can be represented by,
An small section (A to B) will represent the fraction =
Therefore, letter B will match the probability of a dice landing on a number between 1 and 6.
