Let's construct an equation for Canton's population increase as 7220+80n and Holly Spring's population increase with 3200+120n, where n is the number of years. We have to set these equations to each other in order to find when the population of these two places are equal. 3200+120n=7220+80n and n=100.5. After 100 and half years

Answer:
Step-by-step explanation:
Given that a marketing research firm is estimating which of two sodas (A or B) college students prefer.
Sample size of 75 was taken at random.
Since sample size is sufficiently large i.e. >30, and also since samples are taken at random, we can assume that sample proportion
p=
follows a normal distribution with mean = 0.6 and variance = npq = 75(0.6)(0.4)
Yes, this sample is large enough to calculate a confidence interval.
Answer:
12
Step-by-step explanation:
note that (f + g)(x) = f(x) + g(x)
f(x) + g(x) = x + 2 + x² - 2 = x² + x
To evaluate (f + g)(- 4) substitute x = - 4 into f(x) + g(x)
(f + g)(- 4) = (- 4)² + (- 4) = 16 - 4 = 12
