Hi there! :)
<u><em>Answer:</em></u>
<u><em>=28b-57</em></u>
<u><em>*The answer must have a positive sign.*</em></u>
Step-by-step explanation:
<h2><u>Lesson: Distributive property</u></h2>
Distributive property: a(b+c)=ab+ac
First, you expand or multiply by the numbers from left to right.
It change positive to negative sign.
Finally, you add/subtract by the numbers from left to right.
It change positive to negative sign.
<em><u>Final answer is 28b-57</u></em>
I hope this helps you!
Have a nice day! :)

Answer:
36 fries
Step-by-step explanation:
Michael has a probability of 0.3.
Lidia has a probability of 0.1.
Alexandra has the probability of 0.32.
Catherine has the probability of 0.1.
Let the probability of Ronald be x
Sum of all the probabilities must be 1
So,
So, probability of Ronald is 0.18
We are given that here are 200 fries in the basket.
So, the number of fries that Ronald will eat =
Hence Ronald will eat 36 fries.
Answer:
(b)
We can use an estimatior for the population proportion as since we don't know previous info. And replacing into equation (b) the values from part a we got:
And rounded up we have that n=1068
Step-by-step explanation:
In order to find the critical value we need to take in count that we are finding the interval for a proportion, so on this case we need to use the z distribution. Since the confidence level is 99%, our significance level would be given by and . And the critical value would be given by:
The margin of error for the proportion interval is given by this formula:
(a)
And on this case we have that and we are interested in order to find the value of n, if we solve n from equation (a) we got:
(b)
We can use an estimatior for the population proportion as since we don't know previous info. And replacing into equation (b) the values from part a we got:
