Answer:
710%
Step-by-step explanation:
1 bucket of eggs is charged at $16.20 for 450 eggs.
1 dozen = 12
450 = 450/12 = 37.5
The store pays ($16.20/37.5 doz)=$0.432/doz
The store charges ($3.50-0.432) $3.068 more per dozen than they paid.
($3.068/$0.432)(100%) = 710%
Answer: x=5, choice D
Step-by-step explanation:
you have two vertical angles
11x=55
55/11=5
x=5
Answer:
The probability that the sample proportion will differ from the population proportion by less than 6% is 0.992.
Step-by-step explanation:
According to the Central limit theorem, if from an unknown population large samples of sizes n > 30, are selected and the sample proportion for each sample is computed then the sampling distribution of sample proportion follows a Normal distribution.
The mean of this sampling distribution of sample proportion is:
The standard deviation of this sampling distribution of sample proportion is:
The information provided is:
As the sample size is large, i.e. <em>n</em> = 276 > 30, the Central limit theorem can be used to approximate the sampling distribution of sample proportion.
Compute the value of as follows:
Thus, the probability that the sample proportion will differ from the population proportion by less than 6% is 0.992.
Answer:
x - 3
Step-by-step explanation:
(8x + 6) - (7x + 9)
8x - 7x = 1x = x
6 - 9 = -3
x - 3
