Pls help me. My assignment is due in half an hour. Thank you. A rectangular card has a length 3 inches longer than twice the width. The area is 324 inches squared. What are the dimensions of the card in inches? Order your answer from least to greatest.​

w=12 L=27

Step-by-step explanation:

length is twice the width with additional 3 inches

12×2=24+3=27

12×27=324

answer: 12

step-by-step explanation:

because yes

d. 24+-0.114

step-by-step explanation:

the question requires us to calculate the approximate 95% confidence interval for the mean number of ounces of ketchup per bottle in the sample given the following statistics;

sample mean = 24

standard deviation, σ = 0.4

sample size , n = 49

the confidence interval for a population mean is calculated using the formula;

sample mean ± z-score*(σ/sqrt(n))

the z-score associated with a 95% confidence interval, from the standard normal tables, is;

1.96

substituting these values into the formula;

24 ± 1.96*(0.4/7)

= 24 ± 0.112

from the alternatives given, choice d is closest to the above expression;
