Given :
a-b = c-d ...1)
b = d-1 ...2)
c = 6
To Prove :
a = 5
Solution :
Adding equation 1 and 2, we get :
(a-b) + (b) = (c-d) + (d-1)
a = c -1 ...3)
Putting given value of c = 6 in above equation, we get :
a = 6 - 1
a = 5
Hence, proved.
Answer: C
Step-by-step explanation:
This is just a straight definition - for a normal distribution, the percent within 2 standard deviations of the mean is about 95.44%.
The graph that can represent the data most accurately is (a) The y-axis of a bar graph starts at zero fish. One bar is 24 units, another bar is 51 units, and the third bar is 36 units
The given parameters are:
- Aquarium A: 24 fishes
- Aquarium B: 51 fishes
- Aquarium C: 36 fishes
The above dataset can be represented on a bar graph, where the lengths of the bars represent the number of fishes in each aquarium
Hence, the graph that can represent the data most accurately is (a)

A(-2, 2), B(4, 2), C(-6, -1), D(0, -1)
AB = CD = 4 - (-2) = 4 + 2 = 6
BD = AC. Use the formula of a distance between two points:
Substitute the coordinates of the points B and D:
BD = AC = 5
