The mean of 10 randomly selected students is definitely more likely to be closer to 75. 10 randomly selected students to include information and are more like to reflect the class’s scores. Consider an extreme example. Seventy-five students in a class of 100 earned perfect scores. The other 25 earned zeros. The average score of the class would be 75. A sample of 10 random students would almost certainly include more 100s then 0s, but both would be included in the sample. The mean of this samples score is closer to 75 than any individuals.
Answer:
A. Obtuse
F. Scalene
Step-by-step explanation:
<u>There are two ways to classify a triangle:</u>
by <u>angles</u>:
Obtuse - has one angle that is greater than 90°
Right - has one angle that is 90°
Acute - has all angles less than 90°
and by <u>side lengths</u>:
Equilateral - all sides are equal
Isosceles - two sides are equal
Scalene - no sides are equal
In this triangle, there is an obtuse angle (A. Obtuse).
∡ = 132°, which is greater than 90°.
There are no equal sides (F. Scalene).
6 ≠ 7 ≠ 11.9
