Answer:

hello your question lacks the required options but i will provide a general answer to your question

answer : The mean value  and the standard deviation would allow us use a Z-score

Step-by-step explanation:

mean value = 231 minutes

standard deviation ( std ) = 40 minutes

sample size = 40

The parameters that would be applicable while use Z-score are : The given mean value and the standard deviation

This is because the value of a z-score gives us an information on how far we are from the mean score i.e. number of standard deviations

+Zscore means that the score  is above the average value

-Zscore means that the score is below the average value

Please simplify: −23d+81≤−98d+1
Strike441 [17]
- 23 d + 81  \leq -98 d + 1

Subtract 81 from both sides :

-23 d + 81-81 \leq -98d+1 -81

-23d \leq -98d-80

Add 98d to both sides:

-23d +98 d \leq -98d-80+98d

75d \leq -80

Divide both sides by 75 :

\frac{75d}{75}  \leq  \frac{-80}{75}

d \leq =- \frac{16}{15}

hope this helps!.
