What is the similarities between qualitative and quantitative research? Qualitative Data One similarity between qualitative and quantitative research is that raw data is ultimately qualitative. Even though numbers are unbiased, the researcher still has to choose some numbers and disregard others. What are the similarities of qualitative variables and quantitative variables? Qualitative variables are nominal […]

What is the distance between points 10 7 and 2 7 on a coordinate plane? The distance between those two points is 8 because its a straight line… What is the distance between and on the real number line? A simple way to calculate the distance between numbers on a number line is to count […]

How do you write a rule for reflection? To write a rule for this reflection you would write: rx−axis(x,y) → (x,−y). Notation Rule A notation rule has the following form ry−axisA → B = ry−axis(x,y) → (−x,y) and tells you that the image A has been reflected across the y-axis and the x-coordinates have been […]

How do I find the height of an object? 3 Answers. You can calculate the height of an object using the distance and angle. distance * cos(angle), where distance is the horizontal distance to the object, and angle is the angle above horizontal of the top of the object (from the viewer). The result will […]

How do you do conversions in math? To convert a smaller unit to a larger unit (eg to ), divide it by the number of smaller units which are needed to make. To convert from a larger unit to a smaller one, multiply. To convert from a smaller unit to a larger one, divide. What […]

How far away can 100 dB be heard? The effective distance of a 100 dB(A) sounder in a very noisy environment is 1.8m, the distance for a 120 dB(A) sounder is approx 18m (10 times the distance). How many decibels is a screaming child? “Certainly a child’s scream right in the ear can be very […]

Can we do same exercise daily? Doing the same workout every day is one thing. But working out in every day in general is another. The answer to this question depends on the type and intensity of exercise that you’re doing. As a rule, especially for resistance training, rest and recovery days are just as […]

Which is stronger Cu or Zn? Oxidizing agents gain electrons while reducing agents lose electrons. However, in the second reaction, the zinc ion is not able to oxidize the copper metal. Zinc is a better reducing agent than copper. Strong reducing agents have weak conjugate oxidizing agents. What happens when you mix water and zinc? […]

Is high viscosity a strong intermolecular force? High viscosity shows strong intermolecular forces between the molecules as the molecules of the liquid face a greater resistance upon moving. How do cohesive forces affect viscosity? Due to strong cohesive forces between the molecules, any layer in a moving fluid tries to drag the adjacent layer to […]

What is a comparison good? In retail economics and geography, comparison goods are products which are usually higher value and purchased infrequently, such as vehicles, household goods or clothing. Consumers tend to compare products before purchasing them to maximise value and quality. What is a degree of comparison? In grammar, the degrees of comparison relate […]
