What is the reason for an outlier in a graph?

Mathematics
1 answer:
Anna71 [15]3 years ago

It is sometimes called an extreme value. When you graph an outlier, it will appear not to fit the pattern of the graph. Some outliers are due to mistakes (for example, writing down 50 instead of 500) while others may indicate that something unusual is happening

Sean bought 68 3/4 inches of rope . How many 15-inches ropes can he make from it
choli [55]
Length of rope bought by Sean = 68 3/4 inches
                                                   = 275/4 inches
Then
The number of 15 inch rope that can be made by Sean = (275/4)/15
                                                                                         = 275/(4 * 15)
                                                                                         = 275/60
                                                                                         = 4.58
So we can see from the above deduction that Sean can make 4 complete 15 inches ropes and there will be 0.58 inches of rope excess. <span>I hope the procedure and the method of solving is absolutely clear to you. This is the easiest way to get to the solution for such problems.</span>

Need help .... Regular octagon ABCDEFGH rotates 360 degree clockwise about it's center . After how many 45 increments will A' (
oksian1 [2.3K]

Answer:

If the octagon is clockwise, then after 5 times 45 increments A' will coincide with F.

If the octagon is counterclockwise, then after 3 times 45 increments A' will coincide with F.

Step-by-step explanation:

Case 1: Let the octagon is clockwise

It is given that a regular octagon ABCDEFGH rotates 360 degree clockwise about it's center.

There are 8 vertices and the central angle between two consecutive vertices is 45 degrees.

Central angle between AB is 45 degree.

Central angle between AC is

\text{Angle between AB}+\text{Angle between BC}=45^{\circ}+45^{\circ}=2\times 45^{\circ}

Central angle between AD is

\text{Angle between AB}+\text{Angle between BC}+\text{Angle between CD}=45^{\circ}+45^{\circ}+45^{\circ}=3\times 45^{\circ}

Similarly,

Central angle between AE is

4\times 45^{\circ}

Central angle between FA is

5\times 45^{\circ}

Therefore after 5 times 45 increments A' will coincide with F.

Case 2: Let the octagon is counterclockwise

FA=AH+HG+GF

FA=45^{\circ}+45^{\circ}+45^{\circ}

FA=135^{\circ}

FA=3\times 45^{\circ}

Therefore after 3 times 45 increments A' will coincide with F.

Ava and Jiao each swam a two-lap swimming race. Ava took 31.49 seconds to finish her first lap and 30.03 seconds to finish her s
omeli [17]

Answer:

Jiao's total swimming time is 59.73 seconds

Step-by-step explanation:

i) Ava took 31.49 seconds to finish her first lap.

ii) Ava took 30.03 seconds to finish her second lap.

iii) Therefore Ava took 31.49 + 30.03 = 61.49 seconds to complete her two laps.

iv) Jiao finished her two-lap swimming race 1.76 seconds before Ava.

v) Jiao's total swimming time = 61.49 - 1.76 = 59.73 seconds
