What do the factors in(-7x + 60)(x + 4) represent?

The factors in the expression (-7x + 60)(x + 4) represents that the expression is divisible by (-7x + 60) and (x + 4)

Step-by-step explanation:

The factors in the expression (-7x + 60)(x + 4) represents that the expression is divisible by (-7x + 60) and (x + 4)

If we can for an equation as (-7x + 60)(x + 4) = 0 ........ (1) , the the terms (-7x + 60) and (x + 4) are the factors of the equation and that gives (-7x + 60) = 0 and (x + 4) = 0.

From this, we get the values of x as and - 4 which are the roots of the equation (1). (Answer)

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;
