Nirja has 24 marbles. the number of marbles nirja has is 6 more than the number of marbles tim has.
if tim has x marbles, the equation that represents the situation is .
the value of x that makes the equation true is?

x + 6 = 24  

x = 18

Step-by-step explanation:

Nirja has 6 more than Tim

x + 6

It said Nirja has 24 marbles so,

x + 6 = 24

Solve this one step equation to find the value of x

x = 18

Tim has 18 marbles

Hope this helped

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;

the correct answer is 1.7
