Solve 10x + 16 _> 6x +20
A. X _> 9
B. X _> 1
C. X _< 1
D. X _< 9

B. x ≥ 1

Step-by-step explanation:

Step 1: Subtract 6x from both sides

4x + 16 ≥ 20

Step 2: Subtract 16 from both sides

4x ≥ 4

Step 3: Divide both sides by 4

x ≥ 1

And we have our answer!

x ≥ 1 (answer B)

Step-by-step explanation:

Your 10x + 16 _> 6x +20 becomes 10x + 16 ≥ 6x +20.  Combining the x terms results in 4x + 16 ≥  20.  Lastly, we subtract 16 from both sides to obtain

4x ≥ 4, or x ≥ 1 (answer B)

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;
