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.

Please help meee and show all steps please!!!ty

Answer:

x = -4 and x = 5

Step-by-step explanation:

Since $x^2 + 2x$ and $3x + 20$ both equal to y, we know that the expressions equal to each other. We can write a new equation base on that.

$x^2 + 2x = 3x + 20$

Now we solve the equation.

$x^2 + 2x = 3x + 20$

$x^2 - x = 20$

$x^2 - x - 20 = 0$

$(x + 4) (x - 5) = 0$

$x + 4 = 0 ; x -5 = 0$

$x = -4 ; x = 5$

What is the quotient when (x+3) is divided into the polynomial 2x2+3x-9

maks197457 [2]

Problem: 2x^2+3x-9
For a polynomial of the form, ax^2+bx+c rewrite the middle term as the sum of two terms whose product a·c=2·-9=-18 and whose sum is b=3.
Factor 3 out of 3x
2x^2+3(x)-9
Rewrite 3 as -3 plus 6.
2x^2+(-3+6)x-9
Apply the distributive property
2x^2(-3x+6x)-9
Remove the parentheses
2x^2-3x+6x-9
Factor out the greatest common factor from each group
Group the first two terms and the last two terms
(2x^2-3x) (6x-9)
Factor out the greatest common factor in each group.
x(2x-3)+3(2x-3)
Factor the polynomial by factoring out the greatest common factor, 2x-3
(x+3) (2x-3). So, the quotient is 2x-3

Sales tax on a shirt is 0.07 times the cost of the shirt. The sales tax for a shirt is $1.26. Which equation could you use to fi

serious [3.7K]

Answer: First option.

Step-by-step explanation:

According to the explained in the exercise, "c" represents the cost of the shirt before sales tax.

You know that the tax on the shirt is 0.07 times its cost. This indicates a multiplication.

Then, that the sales tax is the product of 0.07 and "c":

$0.07c=sales\ tax$

Knowing that the sales tax for a shirt is $1.26, you can substitute this value into $0.07c=sales\ tax$ in order to find the equation that could be used to find the cost of the shirt before sales tax.

Then, this is:

$0.07c=1.26$
