Answer:
a. B. Frequency is the number of times a particular distinct value occurs. Relative frequency is the ratio of the frequency of a value to the total number of observations.
b. A. A relative frequency is the same as a percentage expressed as a decimal.
Step-by-step explanation:
Frequency is the number of repetitions of a particular observation.
Relative Frequency is the ratio of the frequency of particular observation to the sum of frequencies of all the observations.
The percentage is the proportion of the whole.
Thus, In question (a)
Option B is the only correct answer.
and in question (b)
Option A is the only correct answer.
Answer:
74.
Step-by-step explanation:
Let the number be xy.
Then from the given data
x = y + 3..........(1)
The numerical value of xy is 10x + y so the second equation is
10x + y + 10y + x = 121
11x + 11y = 121 Simplifying:
x + y = 11
x = -y + 11 .........(2) Adding equations (1) and (2):
2x = 14
x = 7
and therefore y = 7 - 3 = 4.
Answer:No value
Step-by-step explanation:there are no value solutions that make x a solution
Answer:
Distance is equal to 10.
Step-by-step explanation:
Use the distance formula: d=√((x_2-x_1)²+(y_2-y_1)²)
d = √(9-3)^2 + (1-9)^2
d = √(6)^2 + (-8)^2
d = √36 + 64
d = √100
d = √10
Hope this helps :)
Answer: There is no need to round in this case, but 159% of 980 is 1558.2.
