The expresssion, –0.25x + 5, models the height of a candle x seconds after it is lit. What is the meaning of the constant term of the function?

the height of the candle before it is lit

Step-by-step explanation:

When the candle is first lit, time is 0.

At tome 0, x = 0 and the height is -0.25(0) + 5 = 5.

The height is 0 at time zero, so the constant term, 5, represents the height of the candle before it is lit.

12

step-by-step explanation:

a triangle's   full angle is 180 degrees so 180 - 156 = 24. 24/2=12

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;
