Pax Math All Answers Correct perimeter of a rectangle formula P=2l+2w or 2(l + w) Peremiter of square formula P= 4 x side Brainpower Read More Triangle Perimeter Formula a+b+c (add 3 sides) Triangle Area Formula A=1/2bh ( base times height, divided by 2) rectangular pyramid a solid figure with a rectangle for its base and triangles for all other faces ( 4 triangles) Rectangular Pyramid Volume V=1/3lwh Formula for perimeter of circle Pie times d (d is diameter) OR C= 2 x pie x r (r is radius which is half of diameter) Area is expressed in what type of units Square units (cm2, ft2, and mi2) Area of a parallelogram formula A=bh Area of a trapezoid formula A= 1/2(b1 + b2)h Apothem a line from the center of a regular polygon at right angles to any of its sides. area of a regular polygon formula A = 1/2ap ( a is length of apothem and p is perimeter) How is area of an irregular polygon determined By decomposing or breaking apart the figure into smaller shapes and then adding those areas together Ex if it consist of a triangle and 2 rectangles add the area of triangle to area of rectangles circle The set of all points in a plane that are the same distance from a given point called the center Circumference The distance around a circle Circumference of a circle formula C=2πr (r is radius) Area of a circle formula A=πr² Arc Part of a circle connecting two points on the circle. Pythagorean Theorem a²+b²=c² Hypotenuse the longest side of a right triangle Volume how much space an object occupies surface area The measurement of the outer surface of an object. Rectangular Prism Surface Area SA=2lw+2lh+2wh Rectangular prism has how many sides 6 How is surface area of a prism measured Adding area of all faces and bases (best to unfold the image to see what shapes are included) How would you determine surface area of triangular prism It consist of 2 triangles and 3 rectangles So area of triangle (twice) and area of rectangle (3 times) Sphere Volume Formula V=4/3πr³ surface area of a sphere formula 4πr^2 Volume of a Cylinder Formula V=πr²h Volume of a Cone Formula V=1/3πr²h Surface Area of a Cylinder 2πrh+2πr² Histogram A graph of vertical bars representing the frequency distribution of a set of data. Box Plot (Box and Whisker Plot) Shows distribution of data values on a number line. Divided into quartiles. Lower extreme (lowest volume that's not an outlier) Higher extreme (highest volume that's not an outlier) Median ( 2nd quartile) 3rd quartile 1st quartile Scatterplot a graphical depiction of the relationship between two variables Independent variable is placed on x axis Dependent variable is placed on y axis If line falls from left to right then correlation is negative If roses from left to right correlation is positive No correlation is simply scattered with no clear pattern line graph Compares variables that change continuously, typically over time Line Plot/Dot Plot Displays the frequency of data on a number like circle graph (pie chart) Shows categorical data with each category representing a percentage of whole data set stem and leaf plot Method displaying sets of data by organizing the numbers by their stems (usually tens digit) and the different lead values (usually one's digit) stem and leaf plot picture What is the mean of data and how do you find it The average of data Found by adding up all the data points, then dividing by the total number of data points. How can mean be expressed Using summation notation Outlier a data point that is substantially outside the normal range of the data points being analyzed Median Middle number (make sure to put numbers in order before trying to determine the median) When is median a good value to use If there are a few outliers in data, having a lot of outliers affects the mean more than median Mode The value that occurs most frequently in a given data set. If two or more data points occur equally then all are considered the mode first quartile the median of the first half of the data set or the largest value of the first 1/4 of data points What does it mean if data lies in the first quartile ? At the first quartile ? In = less than or equal to the median of the first half of data points At = equal to the first quartile What does jt mean if data lies in the second quartile It means between the first quartile and the median What does third quartile refer to Data that lies between 1/2 and 3/4 of the way through the data set (data that lies between the medi
