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:
x=9
Step-by-step explanation:
The goal is to combine our knowledge of geometry area and algebra skills to solve this problems.
We know area of rectangle is
where l is the length and w is the width. We know that one side is 3 less than the other side. We can use L or W but let use L. Let x replace L
One side is x, while the other side is
Both multiply to 54.
or
Distance. is positive so x=9
