The cost of buying cameras is a linear function of the number of cameras bought. the cost of 2, 4, and 8 video cameras is shown in the table. identify the equation in slope-intercept form that represents the function.

Using the information in the table, divide the cost by the number of cameras:

200 / 2 cameras = 100 per camera

400 / 4 = 100 per camera.

You would need to multiply the number of cameras bought by 100 to get the total cost.

The equation would be y = 100x

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;
