Solve the equation -5(s+30)=-17

s = -133/5 = -26.600 ⬇️

Step-by-step explanation:

Step by step solution :

Step  1  :

Equation at the end of step  1  :

 (0 -  5 • (s + 30)) -  -17  = 0

Step  2  :

Step  3  :

Pulling out like terms :

3.1     Pull out like factors :

  -5s - 133  =   -1 • (5s + 133)

Equation at the end of step  3  :

 -5s - 133  = 0

Step  4  :

Solving a Single Variable Equation :

4.1      Solve  :    -5s-133 = 0

Add  133  to both sides of the equation :

                     -5s = 133

Multiply both sides of the equation by (-1) :  5s = -133

Divide both sides of the equation by 5:

                    s = -133/5 = -26.600

One solution was found :

                  s = -133/5 = -26.600

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;
