Unit price at Snacks & More = $17.25 / 3 pound = $5.75 per pound

Healthy Snacking sells a 2.5-pound bag of mixed nuts for $13.75.

Which data set could be represented by the box plot shown below? A horizontal boxplot is plotted along a horizontal axis marked
ludmilkaskok [199]

Answer:

(B)1,3,6,8,10,12,13,13,16,18,19

Step-by-step explanation:

In the box plot:

A left whisker extends from 1 to 6, therefore, the least value is 1.

The box extends from 6 to 16 and is divided into 2 parts by a vertical line segment at 12. Therefore:

  • The lower quartile is 6
  • The median is 12
  • The upper quartile is 16

The right whisker extends from 16 to 19, therefore the highest value is 19.

The set of data that satisfies these conditions where the numbers in bold are the 5- number summary is:

1,3,6,8,10,12,13,13,16,18,19

The correct option is B.

Given the function LaTeX: f\left(x\right)=-5x^2-x+20f ( x ) = − 5 x 2 − x + 20, find LaTeX: f\left(2\right)f ( 2 ). Group of ans
BartSMP [9]

The value of f(2) is -2 ⇒ 1st answer

Step-by-step explanation:

The form of the quadratic function is;

f(x) = ax² + bx + c, where

  • a is the coefficient of x²
  • b is the coefficient of x
  • c is the numerical term
  • x is the domain of the function and f(x) is the range of the function

∵ f(x) = -5x² - x + 20

- f(2) means value f(x) at x = 2

∵ x = 2

- Substitute x in the function by 2 to find f(2)

∵ f(2) = -5(2)² - (2) + 20

∴ f(2) = -5(4) - 2 + 20

∴ f(2) = -20 - 2 + 20

∴ f(2) = -2

The value of f(2) is -2
