Given that Ruby bought 15 cell phone cases for a total of $145.80. This means that each cell phone case costs $9.72 each. She sells each for $19.50, but only 5 out of the 15. So the total earnings she has is $97.50. Therefore, we can say that Ruby did not earn a profit but is experiencing a loss of $48.30. Hope this answers your question.

Akron Cinema sells an average of 500 tickets on Mondays, with a standard deviation of 50 tickets. If a simple random sample is t
Paha777 [63]

Answer:

Step-by-step explanation:

Assuming the number of tickets sales from Mondays is normally distributed. the formula for normal distribution would be applied. It is expressed as

z = (x - u)/s

Where

x = ticket sales from monday

u = mean amount of ticket

s = standard deviation

From the information given,

u = 500 tickets

s = 50 tickets

We want to find the probability that the mean will be greater than 510. It is expressed as

P(x greater than 510) = 1 - P(x lesser than or equal to 510)

For x = 510

z = (510 - 500)/50 = 0.2

Looking at the normal distribution table, the probability corresponding to the z score is 0.9773

P(x greater than 510) = 1 - 0.9773 = 0.0227

Explain how feel about trump being impeached a second time this time for the mobs action​
Artemon [7]

Answer:

I feel like everyone is entitled to their own opinion, but my opinion is that I feel like they shouldn't have done it, because we have been mostly safe when Trump was president. The reason we weren't completely safe is because people are hard headed and don't know how to follow instructions, so again I don't feel ike they should have done him like that, but everyone has their own opinion.

Step-by-step explanation:

Hope this helps!

Have a great day! :)

What is the complex conjugate of 13-21i?
irga5000 [103]

Answer:

To find a complex conjugate, simply change the sign of the imaginary part (the part with the i). This means that it either goes from positive to negative or from negative to positive.

As a general rule, the complex conjugate of <span>a+bi</span> is <span>a−bi</span>.

Therefore, the complex conjugate of <span>3−2i</span> is <span>3+2i</span>.

Hope this helped!!... :D

Please correct me if I'm wrong!!.. :3
