Step-by-step explanation:2 x 2=4 x 2=8
Answer:
Step-by-step explanation:
From the information given,
Mark: 6,7,8,9,10
frequency:5,4,7,10,4
a) Range = highest mark - lowest mark
Range = 10 - 6 = 4
b) The number of students in the group is the sum of the frequency. Therefore,
Number of students = 5 + 4 + 7 + 10 + 4 = 30 students
c) Mean mark = (mark × frequency)/total frequency
[(6 × 5) + (7 × 4) + (8 × 7) + (9 × 10) + 10 × 4)]/ 30
Mean mark = (30 + 28 + 56 + 90 + 40)/30 = 244/30
Mean mark = 8.1

Step-by-step explanation:
The general formula for the total surface area of a right prism is T. S. A. =ph+2B where p represents the perimeter of the base, h the height of the prism and B the area of the base.
Yea what the other guy said
Step-by-step explanation:
1)
Hypotenuse2 = Perpendicular2 + Base2
c2 = a2 + b2
therefore,
c2 = (10)2 in + (24)2 in
c2 = 100 + 576
c2 = 676
c = √676
c = 26
