Answer:
480.6 ; 440.5, 8 mode values
Step-by-step explanation:
Given that :
Given the data :
486, 358, 395, 759,496, 692, 353, 306
Rearranged data: 306, 353, 358, 395, 486, 496, 692, 759
The mean:
Σx/ n
n = sample size = 8
Σx = sum of all data values = 3845
Mean = 3845 / 8
Mean = 480.6
The median :
0.5(n + 1)th term
0.5(8 + 1) th term
0.5(9)th term
= 4.5term
(4th + 5th term) / 2
(395 + 486) / 2
= 440.5
The mode = most frequently occurring data value ; since all the data values have a frequency of 1, then the number of modes = 8.
To find volume, you multiply height x length x width. In this problem, you have to multiply 4 x 1.5 x 2.5. You get 15 in3. I hope this helps!
Answer: U = 14
Step-by-step explanation:
u = 14
u/7 - 1 = 1
add 1 to both sides
u/7 = 2
multiply 2 by 7
u = 14
Answer:
B.
Vertical angles are the same angles of each other.
14 + 7 = 21
3(14) - 21 = 21
