Drag each number to the correct location on the table. Not all numbers will be used.
Airida [17]

Answer:

Complete Table:

Result of Roll ------ Frequency ------- Experimental Probability

1 --------------------------- 22 ------------------- 0.176

2 --------------------------- 13 ------------------- 0.104

3 --------------------------- 18 ------------------- 0.144

4 --------------------------- 29 ------------------- 0.232

5 --------------------------- 37 ------------------- 0.296

6 --------------------------- 6 ------------------- 0.048

Step-by-step explanation:

Required: Complete the table

The table is divided into 3:

1. Result of Roll

2. Frequency (F)

3. Experimental Probability (P)

The relationship between (2) and (3) is:

P = \frac{F}{N}

Where

N = Number of Rolls

N = 125

For Roll of Result = 2

Frequency = 13

The probability is calculated as thus:

P = \frac{13}{125}

P = 0.104

For Roll of Result = 3

Probability = 0.144

The Frequency is calculated as thus:

0.144 = \frac{F}{125}

F = 0.144 * 125

F = 18

For Roll of Result = 4

Frequency = 29

The probability is calculated as thus:

P = \frac{29}{125}

P = 0.232

For Roll of Result = 5

Probability = 0.296

The Frequency is calculated as thus:

0.296 = \frac{F}{125}

F = 0.296* 125

F = 37

For Roll of Result = 6

Frequency = 6

The probability is calculated as thus:

P = \frac{6}{125}

P = 0.048

For Roll of Result = 1.

To get the frequency; we subtract the sum of frequencies of roll of results 2 to 6 from the total number of rolls.

In other words:

Frequency of 1 = Total Rolls - (Frequency of 2 + Frequency of 3 + Frequency of 4 + Frequency of 5 + Frequency of 6)

Frequency of 1 = 125 - (13 + 18 + 29 + 37 +6)

Frequency of 1 = 125 - 103

Frequency of 1 = 22

The probability is calculated as thus:

P = \frac{F}{N}

P = \frac{22}{125}

P = 0.176

A PS4 uses 8.8 watts in stand by mode. How much electricity would be used if you have the PS4 on stand by for 12 hours a day for
noname [10]
The total number of hours on stand by is 12 x 3 x 7 = 252 hrs.
The energy used would be (252 x 8.8)/1000 = 2.22 kW-hours.

Which option identifies the sampling technique represented in the following scenario? An ophthalmologist wishes to measure the r
Zielflug [23.3K]
The answer is C. Systemic random sampling.

By definition, systemic random sampling is a sampling technique where the respondents are selected according to a <em>random starting point </em>(this alone shows that the answer is C.) The researcher then chooses the sample interval, which is the difference between two consecutive  numbers in the progression. 

In this case, the starting point is 8 and the sample interval is 10.

The answer is C.
