The median acceptance rate of the histogram is given as follows:
Just above 30%.
What is the median of a data-set?The median of a data-set is the middle value of the data-set, the value of which 50% of the measures in the data-set are less than and 50% are greater than.
To find the median of the given histogram, first we have to identity the number of measures in the histogram, adding the frequencies as follows:
number of frequencies = 1 + 3 + 5 + 3 + 5 + 5 + 1 + 2 = 25.
The cardinality is odd, of 25, hence the median is the interval of the histogram in which the cumulative frequency reaches 13.
Taking the midpoint of each interval, the cumulative frequencies are as follows:
12.5: 1.17.5: 1 + 2 = 3.22.5: 3 + 5 = 8.27.5: 8 + 3 = 11.32.5: 11 + 5 = 16 -> greater than 13, hence the median is of 32.5.32.5 is just above 30%, which is the correct option.

The heights of the 430 National Basketball Association players were listed on team rosters at the start of the 2005–2006 season. The heights of basketball players have an approximate normal distribution with mean,
= 79 inches
and a standard deviation,
= 3.89 inches.
1. If an NBA player reported his height had a z-score of 3.4, would you believe him? Explain your answer. (Round your answer to two decimal places.)
A z-score of 3.4 equates to a height of ____
Answers
A z-score of 3.4 equates to a height of 92.23
How to solve for the z scoreWe have to find the height of the player given the figures that we have in he question
We have the formula for the height as
z = x - u / sd
where z is the z score of the player = 3.4
x is the average which is not given here. This would be the height
u is = mean which is the value of 79 inches
while the standard deviation is given by sd = 3.89
We have to put these values in the formula that we have here. Such that we would have
3.4 = x - 79 / 3.89
we have to cross multiply
3. 89 * 3.4 = x - 79
13.226 = x - 79
x = 79 + 13.226
x = 92.23
From the value that we have here, we can see that the height of the player that was reported is given as 92. 23.
This is not believable because it would mean that the height is far greater than the height of all of the players which is 79 inches.

All real numbers except 3
Answers
Using the graphical methods [online graph calculator], the domain of (fx) = (x-3)/7x is given as All real numbers except 0. (Option B)
What is a domain in mathematics?A relation's domain and range are defined as the sets of all the x-coordinates and all the y-coordinates of ordered pairs, respectively.
Graphs may also be used to determine the domain and range of functions. The domain of a graph consists of all the input values represented on the x-axis since the domain refers to the set of potential input values. The range is the collection of potential output values represented on the y-axis.
Notice as indicated in the graph that the coordinates or ordered pairs plotted DO NOT go through the origin which is zero. Also notice that the curved lines, extend to all real numbers on the grapy to infinity.
Hence stated as a mathematical expression, the domain would be:
(-∞, 0) ∪ (0,∞)
{x|x≠0}

Which of the following is NOT a requirement for a density curve?
Answers
The option that is NOT a requirement for a density curve is option
A. The graph is centered around 0.
What is a Density Curve?A graph that displays probability is known as a density curve. All probability are represented by 100% of the curve's area under the curve.
Note that you can alternatively state that the area is equal to 1 because 100% is a decimal, which is how we typically express probabilities. Those are some characteristics of a density curve. One particular category of density curves is the normal density curve. They are bell-shaped, symmetric, and unimodal.
Therefore, To view the distribution of a variable in a dataset, utilize density graphs. The graph is plotted across a continuous range of time. Another name for this is a kernel density plot. Histograms are modified into density charts. An idealized representation of a distribution is a density curve, and there is no centered graph at point zero.
