Answer:
P(X≤164) = 0.16
Step-by-step explanation:
We are given that the weights of vegetables are normally distributed with mean
= 172
Standard deviation,
= 8
We need to calculate P(X≤164) we will use Z score to calculate this,
Z=
= 
Z≤ -1
P(Z≤ -1) = 0.1587 (Using normal distribution table)
Rounding to nearest hundredth = 0.16
Now 0.5-0.34 = <u>0.16</u> or <u>16%</u>
Answer:
A
Step-by-step explanation:
The expression 1.25 d means 100% of the price +25% of the price. This means it increased by 25%. Multiplying it by 0.8 means it's value is only 80% of the value now which means it must of had a 20% decrease after increasing. It's now at it's original price.
