Need help solving for relative frequency please!
Sunny_sXe [5.5K]

Answer:

Kindly check explanation

Step-by-step explanation:

Given :

Relative frequency = frequency / total frequency

Total frequency = 389+335+975+351+72 = 2122

Response ________ Frequency __ R/ frequency

Never ____________ 389 _ 389/2122 = 0.180

Rarely ____________ 335 _ 335/2122 = 0.158

Sometimes _________975 _975/2122 = 0.459

Most of the time _____ 351 _ 351/2122 = 0.165

Always ____________ 72 __ 72/2122 = 0.034

The response to a question has three alternatives: A, B, and C. A sample of 120 responses provides 60 A, 12 B, and 48 C. Show th
zimovet [89]

Answer:

CLASS     FREQUENCIES     RELATIVE FREQUENCIES

A                        60                                 0.5

B                        12                                  0.1

C                        48                                 0.4

TOTAL              120                                  1

Step-by-step explanation:

Given that;

the frequencies of there alternatives are;

Frequency A = 60

Frequency B = 12

Frequency C = 48

Total = 60 + 12 + 48 = 120

Now to determine our relative frequency, we divide each frequency by the total sum of the given frequencies;

Relative Frequency A = Frequency A / total = 60 / 120 = 0.5

Relative Frequency B = Frequency B / total = 12 / 120 = 0.1

Relative Frequency C = Frequency C / total = 48 / 120 = 0.4

therefore;

CLASS     FREQUENCIES     RELATIVE FREQUENCIES

A                        60                                 0.5

B                        12                                  0.1

C                        48                                 0.4

TOTAL              120                                  1

Which Graph Represents A function ?<br><br> NEED ANSWER ASAP !!!!
ANEK [815]

Answer:

The very last one is a function

Step-by-step explanation:

The last one is a function because there are no y values that repeat. For example, If the points on one graph are like this; (1, 3) (2, 3); then it cannot be a function, the y values cannot repeat if it is a function.

To make things easier, just try to imagine vertical drawing lines through each point in every graph, if this imaginary vertical line passes more than one point in any graph, then that graph is not a function.

I hope this helps!! :D
