Determine the values of k and p so that the solution is "All Reals" when solving for y:
Angelina_Jolie [31]

Answer:

The value of k is  \pm 9 and The value of p is - 23  

Step-by-step explanation:

Given equation as :

81 y - 17  = k² y + 6 + p

The equation has real solution ,

Now for real solution the equation have no solution

∵ The equation has no solution the ,

The coefficient of y must be equal

I.e 81 = k²

Or, k = \sqrt{81}

∴   k = \pm 9

Again , If the coefficient of y is same then the equation is written as

6 + p = - 17

or, p = - 17 - 6

or, p = - 23

Hence The value of k is  \pm 9 and The value of p is - 23   Answer

What is the percent of change from 4,000 to 600?<br> work too plz
xenn [34]
\frac { n }{ 100 } \cdot 4,000=600\\ \\ 4,000\cdot n=60,000\\ \\ Therefore:\\ \\ n=\frac { 60,000 }{ 4,000 }

\\ \\ =\frac { 60\cdot 1,000 }{ 4\cdot 1,000 } \\ \\ =\frac { 60 }{ 4 } \\ \\ =15

As 15% of 4,000 is 600, the percentage change was -85%.

Which box plot correctly displays the data set with a maximum of 48, a minimum of 27, a median of 36, an upper quartile of 45, a
Vitek1552 [10]

Answer:

Image 1

Step-by-step explanation:

To answer this question, we need to know how to use a box plot.

I've attached an image that demonstrates this well and can teach you what each part of the box plot means.

Specifically, the 2 farthest dots at the end are the minimum and maximum. The two sides where the box starts are the lower and upper quartiles. Finally, the line in the middle of the box is the median.

With this, we can analyze each box plot and determine which one is correct.

<em><u>Box Plot 1: </u></em><em>Everything is plotted correctly- Maximum and minimum plotted correctly, median plotted correctly, upper and lower quartile plotted correctly.</em>

<u>Box Plot 2:</u> Everything plotted correctly EXCEPT maximum of 48 is represented at 46.

<u>Box Plot 3:</u> Everything plotted correctly EXCEPT the upper quartile of 45 is at 39.

<u>Box Plot 4:</u> Upper quartile represented at 39 and maximum represented at 46 are both incorrect.

The set of ordered pairs represented by the graph below can be described as which of the following
Aneli [31]

ANSWER

a relation only

EXPLANATION

The given graph shown in the attachment represents only a relation and not a function.

The reason is that, a vertical line drawn across this graph will intersect this graph at more than one point.

Since the graph fails to pass the vertical line test, the ordered pair represented by this graph represents a relation only.
