If a sample consists of 1900 scores from sample no. 476th will be above the first quartile.

<h3>What are mean, median, and mode?</h3>

The three main methods for identifying the average value of a set of integers are mean, median, and mode.

Adding the numbers together and dividing the result by the total number of numbers in the list yields the arithmetic mean.

The middle value in a list that is arranged from smallest to greatest is called the median.

The value that appears the most frequently on the list is the mode.

Given a sample consisting of 1900 scores.

∴ The no. of samples that would be above quartile is the next sample from (1/4)th of 1900 which is,

= (1/4)×1900 + 1.

= 475 + 1.

= 476.

So from sample no. 476th will be above the first quartile.

What is the leading coefficient of a third degree polynomial function that has an output of 1,272 when x=2, and has zeros of −6,
Gre4nikov [31]

Answer:

<em>The leading coefficient is 3</em>

Step-by-step explanation:

<u>Polynomials</u>

Given the roots of a polynomial x1,x2,x3, it can be expressed as:

p(x)=a(x-x1)(x-x2)(x-x3)

Where a is the leading coefficient.

We are given the roots x1=-6, x2=7i, x3=-7i, thus:

p(x)=a(x+6)(x-7i)(x+7i)

Operating the product of the conjugated imaginary roots:

p(x)=a(x+6)(x^2+49)

Knowing p(2)=1,272 we can find the value of a

p(2)=a(2+6)(4+49)=1,272

Operating:

a(8)(53)=1,272

424a=1,272

Solving:

a=1,272/424

a=3

The leading coefficient is 3

Find the missing angle<br> A) 61.1<br> 49.40<br> B) 56.10<br> D) 59.7
adoni [48]

Answer:

D

Step-by-step explanation:

You have the opposite side given and the adjacent side. That means you will use the tangent.

Tan(theta) = opposite / adjacent

opposite = 6

adjacent = 3.5

Tan(theta) = 6 / 3.5

Tan(theta) = 1.714

Tan-1(1.714) = 59.74

when you get an answer over 1 from the division, you know that the angle is over 45 degrees.
