Answer:

10 Values

Step-by-step explanation:

We would use a set of data for illustration

Given the set of numbers:

1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20

Since we have an even number of data, the median is in between 10 and 11.

(1,2,3,4,5,6,7,8,9,10),(11,12,13,14,15,16,17,18,19,20)

Lower Half: (1,2,3,4,5,6,7,8,9,10)

  • The median of the lower half is in between 5 and 6. So Q_1 is in between 5 and 6.

Upper Half:(11,12,13,14,15,16,17,18,19,20)

  • The median of the upper half is in between 15 and 16. So Q_3 is in between 15 and 16.

Therefore, we have the [position of the first and third quartiles as:

1,2,3,4,5,Q_1,6,7,8,9,10,11,12,13,14,15,Q_3,16,17,18,19,20

There are 10 values in between the first and third quartiles.

Arithmetic sequence help!!!!
eimsori [14]

1) This is not an arithmetic sequence because it has n².

2) To find 5 first terms of this sequence, you can simply substitute n with 1,2,3,4, and 5, and calculate values of a(1),a(2), a(3), a(4) and a(5).

a(n) = 3n²- 1

n=1 a=3*1² - 1 = 3-1=2

n=2 a=3*2² - 1 = 11

n=3 a=3*3² - 1 =26

n=4 a=3*4² - 1 = 47

n=5 a=3*5² -1 = 74

2,11,26,47,74

Answer C. 2,11,26,47,74.

The degree of the polynomial function f(x) is 4.
Lyrx [107]

Answer:

Option A

Step-by-step explanation:

Degree of the polynomial function = 4

That means highest degree term of the given polynomial has power = 4

If the roots of a quadratic polynomial are a, b, c, d then the polynomial function will be,

f(x) = (x - a)(x - b)(x - c)(x - d)

It's given in the question that roots are x = -2, -1, 1 and 3

Therefore, polynomial function will be,

f(x) = (x + 2)(x + 1)(x - 1)(x - 3)

From the given options, graph A shows that the graph intersects the x-axis at x = -2, -1, 1 and 3

Therefore, Option A will be the answer.
