Which compound inequality does represent the phrase all real numbers that are greater than -7 and less than 4?

 Required compound inequality : -7<x<4

Step-by-step explanation:

Let x be an arbitrary real number.

Given phrase: All real numbers that are greater than -7 and less than 4.

i.e. x>-7    and x<4  [We use use '<', '>' signs to show less than or more than]

Combined inequality : -7<x<4

Hence, the required compound inequality : -7<x<4

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;

they go with it happens or they mite give a chance?
