The regular nonagon has rotational symmetry of which angle measures? Check all that apply. 40° 45° 120° 240° 260° 320°

Organizing the data in increasing order to find the outlier and compute the mean

Detailed explanation:

The provided data consists of: [4, 1, 3, 10, 18, 12, 9, 4, 15, 16, 32]

Arranging it in ascending sequence

                               [1, 3, 4, 4, 9, 10, 12, 15, 16, 18, 32 ]

The outlier is identified as 32

Calculating the mean;

Mean=total of data set/quantity of data set

Total= 1 + 3+ 4+ 4+ 9+ 10+ 12+ 15+ 16+ 18+ 32=124

Quantity of data set=11

Mean=124/11=11.27

Answer:

Step-by-step explanation: The error made by the student was dividing the wins by the losses.

The student should have divided the wins by the total number of games played.

Initially, the student ought to have summed 20 and 10 to conclude there were 30 games in total.

Answer:

The solution yields a number equal to -136.

Step-by-step explanation:

Let x represent the number, leading to the following equation:

x + 2 = 7/8 x - 15

Rearranging gives:

x - 7/8 x = -15 - 2

1/8 x = -17

x = -17 * 8 resulting in -136.

In this scenario, the first step is to assign variables.

We define:

x: time measured in minutes

y: distance covered.

The equations formulated are as follows:

For Kathleen:

For Arnob:

At the moment Arnob meets Kathleen, we have:

Next, we isolate x.

We now have:

Answer:

Arnob takes a total of 75 minutes to catch up to Kathleen:
