Picture of the question please?
Answer:
b. The science students
Step-by-step explanation:
If you count the dots, they are the same for both class (9 people) but the range of the science students' scores are higher than the range for the math students, which means that the sum of their scores will be larger than the math students' and since they have the same number of people, the number being divided for the average would be the same, so the science students' average would be greater than the math's.
I hope this helped! ;D
Since these are right triangles you can use the pythagorean theorem
a² + b² = c²
a = one leg of the triangle
b = the other leg of the triangle
c = the hypotenuse
1. 4² + 3² = c²
16 + 9 = c²
25 = c²
√25 = √c²
5 = c
c = 5cm
2. 5² + 12² = c²
25 + 144 = c²
169 = c²
√169 = √c²
13 = c
c = 13in
4. 7² + 9² = c²
49 + 81 = c²
130 = c²
√130 = √c²
11.4 = c
c = 11.4cm
5. a² + 10² = 15²
a² + 100 = 225
a² = 125
√a² = √125
a = 11.2ft
