Answer: sorry the answer is not clear.
Step-by-step explanation:
To calculate mean: Just add up all the numbers, then divide by how many numbers there are.345 + 673 + 728 +775 + 822 +827 +839 + 951 = 5960/8 = 745
633 + 673 + 728 +775 + 822 +827 +839 + 951 = 6248/8 = 781781- 745 = 35 It increases by 35To find the Median, place the numbers in value order and find the middle. BUT, with an even amount of numbers things are slightly different. In that case we find the middle pair of numbers, and then find the value that is half way between them. This is easily done by adding them together and dividing by two. 345 673 728 775 822 827 839 951 The median = 822-775 /2
The median =23.5After the change633 673 728 775 822 827 839 951 The median = 822-775 /2
The median =23.5The median stays the same.
Answer:
E. 35°, 70°
Step-by-step explanation:
Sum of angles add up to 180° in every triangle.
Step 1: Set up equation
a + 2a + 75 = 180
Step 2: Combine like terms
3a + 75 = 180
Step 3: Subtract 75 on both sides
3a = 105
Step 4: Divide both sides by 3
a = 35
So 1 angle is 35°
Step 5: Plug in <em>a</em> to find last angle
2(35) = 70°
Answer:
![P(T\ n\ S) = \frac{1}{14}](https://tex.z-dn.net/?f=P%28T%5C%20n%5C%20S%29%20%3D%20%5Cfrac%7B1%7D%7B14%7D)
Step-by-step explanation:
*Missing Part of the Question*
4 stars
5 triangles
3 circles
3 squares
Required
Determine the probability of triangle being first then square being second
![Total = 4 + 5 + 3 + 3](https://tex.z-dn.net/?f=Total%20%3D%204%20%2B%205%20%2B%203%20%2B%203)
![Total = 15](https://tex.z-dn.net/?f=Total%20%3D%2015)
Represent the triangle with T and square with S
So, we're solving for P(T n S)
![P(T\ n\ S) = P(T) * P(S)](https://tex.z-dn.net/?f=P%28T%5C%20n%5C%20S%29%20%3D%20P%28T%29%20%2A%20P%28S%29)
Solving for P(T)
![P(T) = \frac{n(T)}{Total}](https://tex.z-dn.net/?f=P%28T%29%20%3D%20%5Cfrac%7Bn%28T%29%7D%7BTotal%7D)
![P(T) = \frac{5}{15}](https://tex.z-dn.net/?f=P%28T%29%20%3D%20%5Cfrac%7B5%7D%7B15%7D)
Solving for P(S)
The question implies a probability without replacement;
Hence Total has now been reduced by 1
Total = 14
![P(S) = \frac{n(S)}{Total}](https://tex.z-dn.net/?f=P%28S%29%20%3D%20%5Cfrac%7Bn%28S%29%7D%7BTotal%7D)
![P(S) = \frac{3}{14}](https://tex.z-dn.net/?f=P%28S%29%20%3D%20%5Cfrac%7B3%7D%7B14%7D)
Recall that
![P(T\ n\ S) = P(T) * P(S)](https://tex.z-dn.net/?f=P%28T%5C%20n%5C%20S%29%20%3D%20P%28T%29%20%2A%20P%28S%29)
![P(T\ n\ S) = \frac{5}{15} * \frac{3}{14}](https://tex.z-dn.net/?f=P%28T%5C%20n%5C%20S%29%20%3D%20%5Cfrac%7B5%7D%7B15%7D%20%2A%20%5Cfrac%7B3%7D%7B14%7D)
![P(T\ n\ S) = \frac{15}{15 * 14}](https://tex.z-dn.net/?f=P%28T%5C%20n%5C%20S%29%20%3D%20%5Cfrac%7B15%7D%7B15%20%2A%2014%7D)
![P(T\ n\ S) = \frac{1}{14}](https://tex.z-dn.net/?f=P%28T%5C%20n%5C%20S%29%20%3D%20%5Cfrac%7B1%7D%7B14%7D)
Hence, the required probability is
![P(T\ n\ S) = \frac{1}{14}](https://tex.z-dn.net/?f=P%28T%5C%20n%5C%20S%29%20%3D%20%5Cfrac%7B1%7D%7B14%7D)
