Hunter and Brian are creating a poster for a project and they need to combine two different size boards to create their project.

shepuryov [24]

Answer:

<em>The maximum area of the second board must be $(5x^2+3x-6)$ square inches.</em>

Step-by-step explanation:

The total area of two different size boards cannot exceed $(7x^2-6x+2)$ square inches.

The area of one board is $(2x^2-9x+8)$ square inches.

Suppose, the area of the second board is $y$ square inches.

That means......

$y+(2x^2-9x+8)\leq 7x^2-6x+2\\ \\ y\leq (7x^2-6x+2)-(2x^2-9x+8)\\ \\y \leq 7x^2-6x+2-2x^2+9x-8\\ \\ y\leq 5x^2+3x-6$

So, the maximum area of the second board must be $(5x^2+3x-6)$ square inches.

solve the average time for a student to complete this quiz is 24 24 minutes with a standard deviation of 2 minutes. What is the

LuckyWell [14K]

Answer:

The correct answer is "(18, 30) minutes".

Step-by-step explanation:

Mean,

= 24

Standard deviation,

= 2

The range of minutes where 99.7% of individuals completed the quiz will be:

= $Mean \pm 3\times Stdev$

On substituting the values, we get

= $24 \pm 3\times 2$

= $24 \pm 6$

now,

= $24-6$

= $18$

Or,

= $24+6$

= $30$

i.e., 18 to 30 minutes

X/2 + 3/2 < 5/2 give solution

Nataly [62]

Start with

$\dfrac{x}{2}+\dfrac{3}{2}$

Multiply the whole equation by 2. Since 2 is positive, we don't need to switch the inequality sign:

$x+3$

Subtract 3 from both sides:

$x$
