Answer: Obtuse triangle.
Step-by-step explanation:
1. By definition, you have:
- If the square of the length of the longest side is greater than the sum of the squares of the lengths of the other two sides, then the triangle is classified as "obtuse".
- If the square of the length of the longest side is less than the sum of the squares of the lengths of the other two sides, then the triangle is classified as "acute".
- If the square of the length of the longest side and the lenght of the other two sides are equal, then it is a right triangle.
2. Based on this information, you have:


3. The longest side is greater than the other two sides. therefore, it is an obtuse triangle.
Answer: y = 3.5 x+ 43.8
Step-by-step explanation:
Here x represents the number of years after 1990
Thus, we get the table that is used to find the equation will be,
x 0 2 4 6 8
y 45 51 57 61 75
Let the equation that shows the above data,
y = b + a x ---------(1)


By the above table,




By substituting these values in the above value of a and b,
We get b = 43.8 and a = 3.5
Substitute this value in equation (1)
we get, the equation that shows the given data is,
y = 3.5 x + 43.8
⇒ Option (3) is correct.
Answer:
<u>Mode = 1</u>
Step-by-step explanation:
<u>Relation between the Central Measures of Tendency</u>
- Mean, Median, and Mode are commonly referred to as the Central Measures of Tendency
- The formula between the three is given by :
- ⇒ <u>Mode = 3Median - 2Mean</u> or <u>Mode + 2Mean = 3Median</u>
<u></u>
<u>Solving</u>
- Median = 5
- Mean = 7
Therefore,
- Mode = 3(5) - 2(7)
- Mode = 15 - 14
- <u>Mode = 1</u>
