How do you graph f of x equals 75x?
y = f(x) = 75x has a slope of 75 (steep) and an x,y intercept of (0,0). Graph it as a very steep, straight line passing through the origin from lower left to upper right.
What are the lower bound estimate and the upper bound estimate found by rounding to the greatest place 937 and ndash 156 A. lower bound 700 upper bound 800 B. lower bound 700 upper bound 900 C. lower?
The answer is B.
How do you calculate the inter quartiles for these number's 65 71 71 76 77 79 81 82 84 86 87 92 92 103 I get that the median is 81.5 but now I am stuck?
The cumulative frequency curve is shaped like an S. The lower quartile is 1/4 the way up on the cumulative frequency axis. The upper quartile is 3/4 the way up on the cumulative frequency axis The inter-quartile range is the upper quartile minus the lower quartile as plotted on the horizontal axis. Further details can be found in a higher level maths text book.
In which direction does the x-axis run?
Generally the x-axis is displayed on a 2-dimensional Cartesian Coordinate system running horizontally (left to right - for negative to positive values of x) In a 3-D graph, the x-axis is usually shown running diagonally from upper right to lower left (for negative to positive values of x) . In a 3-D graph, the y-axis is the one running horizontally and the z-axis is vertical.
How do i write all real numbers in an inequality?
You cannot list them: unless the inequality is trivial, since there are infinitely many real numbers in any range. You need toidentify the lower bound;determine whether or not the lower bound is included (
Are the upper and lower quartiles classed as averages?
No.
Are the lower and upper quartiles of a box and whisker plot always whole numbers?
Yes
How do you find the lower and upper quartiles with only 5 values?
The lower quartile is the second smallest and the upper quartile is the fourth smallest (second largest).
How do you find upper and lower quartile?
See related link. Upper and lower quartiles are the 75 and 25% percentile measures.
What does IQR mean in math?
The interquartile range (IQR) is a measure of variability, based on dividing a data set into quartiles. Quartiles divide a rank-ordered data set into four equal parts.
What is the interquartile range a measure of?
The interquartile range is well known as a measure of statistical dispersion. It is equal to difference between upper and lower quartiles. The quartiles is a type of quantile.
What quartile rage difference of the upper and lower quartiles?
There is no need to lose your rag!It is the inter-quartile range.
What are the upper and lower quartiles of the data set?
The upper quartile is the value such that a quarter of the data are greater than that value. Similarly, the lower quartile is the value such that a quarter of the data are lower than that value.
What are the upper and lower quartiles?
The upper quartile of a set of data is a value such that a quarter of the observations are greater than that value. The lower quartile is similarly defined as the value such that a quarter of the observations are less than that value.
Can the lower and upper quartiles be equal?
Yes. Usually the value of the lower quantile, median, and upper quantile are in ascending order, how if for the particular set of data, if all values are the same, then these three measures can be the same.
What does a box and whisker plot show about the data?
It is marked by the minimum, and maximum, the median, as well as the lower and upper quartiles. It also shows the skewness of the data.
The generic equation suggested by a graph showing a diagonal line from the lower left to the upper right of the graph?
y = ax
