3[w-5]=[2w+10] thank you

Step-by-step explanation:

So we have the equation (I'm assuming the brackets are synonymous with parentheses):

Distribute the left:

Add 15 to both sides:

Subtract 2w from both sides:

And we're done!

Edit: Typo

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;

where is the diagram? shown below where? ?
