Hi!
The correct answer is: C. It is the data value that appears the most often in the set.
<h3>
Explanation</h3>
The mode of a set of values is the number which is the most frequently appearing, or most repeating value in the range. The numbers that show one time each are
A - 16 , C - 25 , D - 3
While 13 appears three times with the dishes labelled
B , E and F
So, the value that appears the most times is 13, and hence 13 is taken as the mode of this data set
<h3>Hope this helps!</h3>
Answer:
Because the mass of electrons and protons is very small
Explanation:
The gravitational force exerted between two objects is given by:
where
is the gravitational constant
m1 and m2 are the masses of the two objects
r is the distance between the two objects
The mass of a proton and of an electron is very small, so the gravitational force involved in case of such particles is very weak. Let's calculate for example the gravitational attraction between one proton and one electron at a distance of r = 1 m. We have:
- Proton mass:
- Electron mass:
So, the gravitational force between the two particles is:
Which is a very weak force.
By comparison, let's calculate instead the electromagnetic force between a proton and an electron (both having a charge of ) still separated by a distance of r = 1 m. We have:
Which we see is much stronger than the gravitational force (almost by a factor
Answer:
a) To the nearest tenth the average value of the measures is 217.4cm
b) The standard deviation for the four measurements is 0.415
Explanation:
The average is the result of adding all the values and dividing by the number of measures, in this case 4 then
a) To the nearest tenth the average value of the measures is 217.4cm
The standard deviation equals to the square root of the variance, and the variance is the adition of all the square of the difference between the measure and the average for each value divided by the number of measurements
So first, we must calculate the variance:
.
.
.
.
.
This represent the difference between the average and the measurements.
Now calculate the standard deviation
Standard deviation =
Standard deviation =
Standard deviation = 0.415
b) The standard deviation for the four measurements is 0.415
This measure represent a standard way to know what is normal in this sample. so the differences between the average should be of ±0.415
