Answer:

3 is the correct answer (see explanations for each possible choice)

Step-by-step explanation:

1 cannot be right because 3 times smaller than 9 would be 3 as 1/3*9=3

2 cannot be right because 3 less than 9 is 9-3=6

3 is right because 3 times as much as 9 is 9*3=27

4 cannot be right because 3 more than 9 is 3+9=12

Step-by-step explanation:

First we eliminate any answers that can't be the answer.

2) can be eliminated because it implies subtraction instead of multiplication. Same with 4).

Now it is narrowed down to 1) and 3).

1) it is 3 times smaller than 9

3) it is 3 times as much as 9

It is not 1). The keywords 'times smaller' implies division.

So the answer is 3).

Hope it helps!

The number of peanuts in bags is normally distributed with a mean of 184.7 peanuts
ioda

Standard deviation = 3.3

The data point = 178

The mean = 184.7

<h2>Further Explanation</h2>

To calculate the Z-score of a bag containing 178 peanuts, we should use the formula to calculating a z-score.

The formula for calculating a Z-score is as follows

z = \frac{data Point - Mean}{Standard Deviation}

This also implies

z = \frac{178 - 184.7}{3.3}

Z= -2.03

therefore, the correct answer is -2.03

A z-score determine the number of standard deviation from the mean a data point is.

some important factors about z-score include:

  • if it is a positive z-score, it indicates the data point is above average
  • if it is a negative Z-score, it indicates the data point is below average
  • if the z-score is close to 0, it then means the data point is close to average
  • if the z-score is above 3 or below -3, it is considered to be unusual
