Weights of the vegetables in a field are normally distributed. from a sample carl cornfield determines the mean weight of a box of vegetables to be 172 oz. with a standard deviation of 8 oz. he wonders what percent of the vegetable boxes he has grouped for sale will have a weight less than 164 oz. _ carl calculates the z-score corresponding to the weight 164 oz. _ using the table (column .00), carl sees the area associated with this z-score is 0. carl rounds this value to the nearest hundredth or 0. _ now, carl subtracts 0.50 - 0.34 = 0._ or _%

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 = 0.16 or 16%

135 is your answer

step-by-step explanation:

try 180 times three then divide that number by 4 (sides) to get your answer. im glad to : )

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.
