Write a two column proof for the following statement. “Given that 2( -x + 4) = 3 , prove that x = 5/2.

2(-X+4)=3. x= 5/2. PLUG IN X!

2(-5/2+4)=3. Distribute the 2

2× (-5/2) = -5

2×4=8

-5+8= 3

Step-by-step explanation:

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;

there are no answer choices
