How do architects use trigonometry?

A simple example of trigonometry used in architecture is to find the height of a building standing a certain distance from the building. Architects know the distance to the building and the angle at which they stand in relation to the top of the structure. Using angle calculations for sines and cosines, the height of the building can be measured.\nArchitects during the Renaissance measured the width of facades using special tools and angle calculations. Dartmouth reveals illustrations of trigonometric measurements were commonplace in the mid-1500s. Raphael used a tool called a bussola, a compa..

What is non-response bias?

This type of bias often occurs in questionnaires and surveys and can take two primary forms. The first form is item nonresponse, which refers to respondents agreeing to take part in a survey but not answering specific questions. The second form is referred to as unit nonresponse, in which an individual designated to take part in a survey isn't available to participate.

How do you convert 330 ml to oz?

Know the conversion rateOne liquid ounce contains approximately 29.57353 milliliters of volume. In most cases, it is appropriate to round to 30 milliliters.\n\nThe conversion equations are: 1 oz = 29.57353 ml, or approximately 30 ml and 1 ml = 0.33814 oz, or approximately 1/30 ozMultiply by the rateIf you have 330 ml that you want to convert to liquid ounces, you must cancel out the units. A unit divided by itself is cancelled. Because 1 ounce is about equal to 30 ml, (1 oz)/(30 ml) = 1 and can be multiplied to change the units and not the value.\n\n330 ml * 1 oz / 30 ml = 11 oz * ml / ml = 1..

What is percent deviation?

Percent deviation is calculated by first subtracting the theoretically expected results from the actual data collected to get the deviation. That number is then divided by the theoretically expected results and multiplied by 100 to create a percent. A negative percent deviation shows that the measured number is lower than the theoretical value. A positive percent deviation means that the measured number is higher. A percent deviation lower than one correlates with accurate results and careful measurements.

What are the names of graphs?

Bar graphs are used for displaying qualitative data. Each category in a set of qualitative data is represented by a bar, and the bars are arranged by order of frequency. Pie or circle graphs display data in the form of a pie. Each "slice" of the pie represents a different data group. A histogram is similar to a bar graph in that it uses bars, but it displays quantitative versus qualitative data.\nStem and leaf plots divide quantitative data by the highest data point and the remaining points of value. The stem is used for the highest data point, while the leaf is used for the other values. Dot ..

How do I calculate the upper or lower quartile?

Quartiles divide a set of numbers into four equal parts. To find the highest and lowest quartiles in a data set, first find the median of the entire set of numbers. Treat the sets of numbers above and below the median as separate sets, and then locate the medians of these groups. The median of the lowest set of numbers corresponds to the lowest, or first, quartile. The median of the entire set corresponds to the second quartile, whereas the median of the highest set corresponds to the highest, or third, quartile.\nQuartiles are calculated differently for odd and even numbers of values. If a da..

What is a bar graph scale and interval?

For a vertical bar graph, the scale for the vertical axis usually begins at zero and goes up to above the maximum data point. However, the scale does not have to start at zero. For instance, the sales figures for a company in October, November and December are $77, $78 and $82 respectively. If the vertical scale is from zero to 90 with an interval of 10, the difference in sales between the months is hardly noticeable. However, if the scale is from 74 to 85 with an interval of 2, the difference in sales between the months becomes very noticeable.

What do you call a person who is 100 years old?

People who live to age 100 are generally women who live in urban areas. Of those who reach age 100, only one of 1,000 reaches 110. These people are super centenarians. Only 34 people in recorded history have reached a confirmed age of 115 as of 2014. The President of the United States traditionally sends a letter of congratulations to citizens who reach this age.

What jobs use fractions?

Many professional titles such as computer programmer, statistician, actuary, quantitative analyst, scientist, economist, urban planner, lawyer and judge, all require at least some knowledge or use of fractions. Other job categories that commonly require the use of fractions include business, sales, architecture, scientific fields, art and design and the financial sector. Another major field that uses fractions is construction, which includes carpenters, painters, electricians, roofers and boilermakers, as XP Math denotes.\nSurprisingly, some jobs that require the use of fractions include agric..

What are the factors of 65?

Except for the number one, any given natural number will have itself and one as factors, so one and 65 are the easiest factors to identify. The remaining factors are found by attempting to divide 65 by prime numbers, from least to greatest, until halfway to 65.\nA prime number is a number whose only factors are one and itself, so the smallest prime number is two. Since 65 is an odd number, it cannot be divided by two, which eliminates two as a factor and any multiple of two.\nThe next prime number is three. However, a number is not divisible by three if the sum of its digits cannot be divided ..
