Answer:
There is no x in the equation, bu the equation you posted equals 20.
Step-by-step explanation:
22+3−5
25-5=20
Solution :
It is given that :
Number of students in a random sample majoring in communication or psychology at an university = 250
Total number of students majoring in psychology = 100
Number of students majoring in psychology those who are happy = 80
So number of students majoring in psychology those who are not happy = 20
Total number of students majoring in communication = 250 - 100 = 150
Number of students majoring in communication those who are happy = 115
So number of students majoring in psychology those who are not happy = 35
a). Probability of the students happy with their major choices are

= 0.78
b). Psychology major 
= 0.4
c). Probability of the students who are happy with the communication as the choice of major =
= 0.46
d). Students unhappy with their choice of major given that the student is psychology major =
= 0.018
Answer:
Therefore, Company B is offering the lowest price/lb at $12.73/lb.
So, Company A's price / lb = ($32.50/2.5lbs) = $13.00/lb
Step-by-step explanation:
To determine price per lb, divide dollar amount by lbs.
- Company A sells 2 1/2lbs (2.5lbs) for $32.50
- Company B sells 2 3/4lbs (2.75lbs) for $35.00
And, Company B's price / lb = ($35.00/2.75lbs) = $12.73/lb
Answer:
And....what are the options? or are we suppose to know answer that?
Answer:
Level 2:
45 x 45 = 2025
28 x 28 = 784
2025 + 784 = 2809
(sqrt)2809 = 53
<u>53 units</u>
Level 3:
(Start by graphing the coordinates)
Your shape should have one leg of 14 units, and one leg of 8 units.
14 x 14 = 196
8 x 8 = 64
196 + 64 = 260
(sqrt)260 = 16.1245155
(rounded to nearest tenth)
<u>16.1 units</u>
<u></u>
I`m not sure about the other two though, sorry :/
