In a video game, two objects move around the screen according to the equations r = 4cos(θ) and r = –1 + 2cos(θ). Which coordinates represent a possible collision point of the objects? (Negative 2, StartFraction 2 pi Over 3 EndFraction) (Negative 2, StartFraction 5 pi Over 6 EndFraction) (2, StartFraction 2 pi Over 3 EndFraction) (2, StartFraction 5 pi Over 6 EndFraction)

step-by-step explanation:

sry but any answer choices

lockers 1, 4, 9, 16, 25, 40, and 49 are open

i ran through it by the other answer is wrong

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;
