Answer: 7/18
Step-by-step explanation:
Number of customers at Eva's boutique = 90
Number of customers who wore a size extra-large = 35
The probability that a randomly selected customer wore a size extra-large will be:
= Number of customers who wore a size extra-large / Number of customers at Eva's boutique
= 35 / 90
= 7/18
Therefore, the probability that a randomly selected customer wore a size extra large is 7/18.
260 bagels in 10 hrs.....260/10 = 26 bagels per hr <== unit rate
if they can bake 26 bagels per hr.....in 24 hrs, they can bake (24 * 26) =
624 bagels
Answer:
8 and 2.529
Step-by-step explanation:
The computation of the mean and the standard deviation is shown below:
Given that
Total number of questions is n = 40
The Probability of correct answer is p =
So, the probability of the wrong answer is q = =
Moreover, this is the binomial distribution
Based on the above information
The mean is
= 8
Now the variance is
=
So, the standard deviation is
= 2.529
hence, the mean and the standard deviation is 8 and 2.529 respectively
