Leah wants to sign up for a membership at a gym. The gym charges a one-time $50 fee to sign-up, and then charges $20 per month. Write an inequality for the number of months Leah can be a member if she can only spend at most $300 at the gym.

the ratio of balloons to tables is 5: 2 and the constant variation is 5.

the equation is y=5x

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;

i would say true? if the unit was informational and it "refreshed your understanding", then true.
