We are given a two-way table that represents the frequency of three types of music.
Hence, the relative frequency table is given by:
Female Male Total
Country 145/1015 106/1015 251/1015
Rap 158/1015 240/1015 398/1015
Rock 214/1015 152/1015 366/1015
Total 517/1015 498/1015 1015/1015
Female Male Total
Country 0.143 0.104 0.247
Rap 0.155 0.237 0.392
Rock 0.211 0.150 0.361
Total 0.509 0.491 1
Hence, clearly we could see that the relative frequency of the music country is much low as compared to that of Rock and rap.
Hence, there is a much difference between the bar of Country as compared to Rock and rap.
and there is a low difference between the bar of rock and rap.
Answer:
The square root of 85
Step-by-step explanation:
The formula to find out the distance between the points is shown below:
The Distance is
where,
x_1 = -3
y_1 = -1
x_2 = 4
And, the y_2 = 5
Now place these values to the above formula
So, the distance is
= 9.22 units
Hence, the distance between points M and N is 9.22 units or the square root of 85
Hence, the second option is correct
Draw a right triangle (attachment below):
Length of the vertical line = 6 units
Length of horizontal line = 8 units
a^2 + b^2 = c^2
6^2 + 8^2 = 100
Square root of 100 = 10
The distance between the two points is 10 units.
