A bag contains 6 red marbles, 6 white marbles, and 4 blue marbles. Find P (red or blue)A.) 2/3
B.) 5/8
C.) None are correct
D.) 3/4
Answers
If there are 6 red marbles, 6 white marbles, and 4 blue marbles, then there are 16 marbles total. To find the probability (P) of either the red or blue marbles, you will add together the number of red and blue marbles, and divide that by the total:
(6 + 4) / (6 + 6 + 4)
10/14
This fraction can further reduce to 5/8 (by dividing both the numbers by 2).
Answer:
5/8

Answers
Answer: The correct option is (A) a shift down 1 unit.
Step-by-step explanation: The given functions are:
we are given to select the correct option which gives one of the transformations applied to the graph of f(x) to produce the graph of g(x).
We have
Comparing the equation of p(x) with that of f(x), we conclude that the transformations are
(i) a horizontal shift of 7 units to the right,
(ii) a vertical shift of 1 unit downwards.
So, one of the correct transformations is - a shift down by 1 unit.
The graphs of f(x) and p(x) are attached below.
Thus, (A) is the correct option.

b)The original pulse rates are measured with units of "beats per minute." What are the units of the corresponding z-scores?
Answers
Answer:
a) Mean=0 and Standard deviation=1
b) The z-scores have no units of measurement
Step-by-step explanation:
When we convert all the pulse rates of women to z-scores using the formula;
the mean is 0 and the standard deviation is 1.
The reason is that, the resulting distribution of z-scores forms a normal distribution which has a mean of 0 and a standard deviation of 1.
b) The z-scores are standardize scores and has no units of measurement. They give us how many standard deviations below or above the mean of the corresponding values.
Final answer:
Converting pulse rates into z-scores standardizes them into a standard normal distribution, yielding a mean of zero and a standard deviation of one. Z-scores are dimensionless and do not carry original physical units of measurement.
Explanation:
The question is asking about the properties of a z-score in the context of pulse rates of women. Here is the answer:
a) When converting to z-scores, regardless of the population parameters, the mean (μ) will always be 0 and standard deviation (σ) always 1. This conversion process is called standardization, which results in a standard normal distribution.
b) In the context of z-scores, the units are dimensionless. Because a z-score result is derived from a mathematical manipulation and not a direct measurement, it does not carry physical units like "beats per minute" in pulse rates. This characteristic enables us to make meaningful comparisons between different types of data.
