Step-by-step explanation:
Since there are 4 people who answered that they had 0 number of scarves we put 4 0's in a set of numbers. Then we see that there are 2 people who have 1 scarf. so there are 2 1's and we keep on going down the line.
{0,0,0,0,1,1,2,3,3,4,5,5} there are 12 numbers here
so we add up all of them
1+1+2+3+3+4+5+5=24
then divide that number by 12 because that's how many numbers there are
24/12=2
The mean of the numbers is 2
Hope that helps :)
Answer:
b = 230 degrees a= 25 degrees
Step-by-step explanation:
d and e are right angles (90 degrees) because when tangent meets radius at circumference a right angle is formed.
c= 180 - 65 - 90 = 25 degrees because angles in a triangle add up to 180
both triangles are congruent as they share the middle line, they have tangents that meet radi(which are equal), and both have right angles. this means that all angles are same in the triangles so a =c =25 and f=65.
65+65=130
360-130 = 230
because angles around a point add up to 360.
b=230

Answer:
The answer is A
Step-by-step explanation:
7² + 10² = c² where c = hypotenuse
49 + 100 = c²
149 = c²
c = √149 feet
