In the following equation, which is the dependant variable? p=2l+2w

P is the dependent variable

Step-by-step explanation:

Its a formula for the perimeter of rectangle.

P represents the perimeter and l is the length and w is the width

The perimeter of rectangle depends on the length and width of the rectangle.

'l' and 'w' are the independent variables

P is the dependent variable because P depends on the length and width.

yes

yes yes 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;
