show a 0 frequency. Lastly, he says that the graph is not symmetrical. Why is Dean incorrect?The graph does not show a peak.There is no cluster in this data set.The graph does not show intervals with 0 frequency.The graph is symmetrical.

Find the first four terms of the sequence an = 4n-6
natulia [17]

Answer:

The first four terms of the sequence are-6, -2, 2 and 6

Step-by-step explanation:

The given sequence is a_n=4n-6

In order to find the first four term of the sequence we put n =0, 1, 2 and 3.

For n =0

a_0=4(0)-6=-6

For n =1

a_1=4(1)-6=-2

For n =2

a_2=4(2)-6=2

For n =3

a_3=4(3)-6=6

Therefore, the first four terms of the sequence are

-6, -2, 2 and 6

Use the following set of data: 78, 78, 83, 85, 89, 91, 95, 98 What is the mode for the set of data?
Yuliya22 [10]

To find the mode you need to put all the numbers given in order, then count them and decide which number occurs the most.

Given the number you have here, we're going to put them in order, like so,

78, 78, 83, 85, 89, 91, 95, 98 (they were in order already)

Now we see which number occurs the most.

The number would be 78

~Hope this helped!
