Answer:
Step-by-step explanation:
1 and 2 are vertical angles
B) {56, 66, 95, 90, 57, 66, 69, 68, 76, 64, 51}
{56, 66, 95, 90, 57, 66, 69, 68, 76, 64, 51} is the only data set that matches the maximum and minimum, upper and lower quartile, and median values.
The answer is 2/7 = 16/56
answer key
78.4
Multiply 7 x 4 =28
Then Multiply 28 x 2.8 = 78.4

Given - Twice a no. decrease by 22 is 48
To find - The no.
Solution -
Let the no. be X
According to the question, equation made is -
2x - 22 = 48
2x = 48 + 22
2x = 70
x = 70/2
X= 35
Verification -
35 ×2 - 22 = 48
70 - 22 = 48
48= 48
LHS = RHS
hence proved
20
8/2 equals 4 and 5 x 4 = 20.
