Tyler tried to solve an equation step by step.
3(x + 4) = -18
3.2 + 12 = -18
Step 1
3x = -30
Step 2
x = -10
Step 3
Find Tyler's mistake.

Step-by-step explanation:

he llo :

3(x + 4) = -18

divid by 3 : x+4 = -6

x+4-4 = -6-4

x = -10

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;

it is x equals 3   plese mark me really need it
