Simplify the expression (4+105x) +5

Answer and step-by-step explanation:

Break the bracket and you would get:

4 + 105x + 5

= 4 + 5 + 105x

= 9 + 105x (this form is simpliest)

If you even want to put the common factor, it would be:

3 * (3 + 35x)

Hope this helped :3

i belive those are the ones that are under 90 degreese.

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;
