Step-by-step explanation:
Answer: See explanation
Step-by-step explanation:
Le the number be x and x+2
The information given can be formed into and equation as:
(x + 2)² = x² + 120
(x + 2)(x + 2) = x² + 120
x² + 2x + 2x + 4 = x² + 120
Collect like terms
x² - x² + 2x + 2x = 120 - 4
4x = 116
x = 116/4
x = 29
The smallest number is 29
The larger number is x + 2 = 29 + 2 = 31
Answer:
Final answer is A. ![P(A^c)=\frac{4}{7}](https://tex.z-dn.net/?f=P%28A%5Ec%29%3D%5Cfrac%7B4%7D%7B7%7D)
Step-by-step explanation:
From table we see that there are 7 places in the list.
Event A = The place is city.
Then
indicates the place is NOT city.
From table we see that there are 4 names "India, Peru, Canada, Mexico" which are not city.
Hence probability that the chosen place is not city is given by:
![P(A^c)=\frac{4}{7}](https://tex.z-dn.net/?f=P%28A%5Ec%29%3D%5Cfrac%7B4%7D%7B7%7D)
Hence final answer is A. ![P(A^c)=\frac{4}{7}](https://tex.z-dn.net/?f=P%28A%5Ec%29%3D%5Cfrac%7B4%7D%7B7%7D)
Answer:
Jimmy ran 12 miles last week.
Step-by-step explanation:
32-20=12
<span> a. each candy has 4 choices, so 4^3 = 64
b. using the stars and bars formula, (3+4-1)C3 = 6c3 = 20
c. in 1 box , in 2 boxes or 3 boxes: 3c3 +3c2 + 3c1 = 7
d. in 1 box, 2 boxes or 3 boxes = 3
e. in 1 box (4) , in 2 boxes : 2combos (AA|B & AB|A) distributed to boxes in 4!/2! ways, and 1 each a box distributed to boxes in 4!/2! ways = 4+24+12 = 40 ways</span>
