Answer:

In elementary algebra, a trinomial is a polynomial consisting of three terms or monomials.

The definition of a trinomial is a math equation that has three terms that are connected by plus or minus notations. An example of a trinomial is 6x squared + 3x + 5.

A polynomial with three terms is called a trinomial. Trinomials often (but not always!) have the form x2 + bx + c.

Answer:

The 95% confidence interval is (29.54 - 53.46}

Step-by-step explanation:

given data:

$\hat X = 41.5$

Se = 6.1

n = 755

a) best estimate $\hat x = 41.5$

b) at 95% confidence interval

$\alpha = 1- 0.95 = 0.05$

$\alpha /2 = 0.025$

$z_{\alpha/2} = z_{0.025} = 1.96$

at 95% confidence interval for [/tex]\mu[/tex]

$\hat x \pm z_{\alpha /2} \times Se$

$41.5 \pm 1.96\times 6.1$

$41.5 \pm 11.96$

The 95% confidence interval is (29.54 - 53.46}

A roped-off area of width x is created around a 30- by 10-foot rectangular museum display of Native American artifacts. The comb

Answer: $4x^{2}+80x-500=0$

Step-by-step explanation:

1. You know that:

- The roped-off area whose width is represented with <em>x,</em> it is created around a rectangular museum.

- The dimensions of the rectangular museum are: 30 ft by 10 ft.

- The combined area of the display and the roped-off area is 800 ft².

2. The area of the rectangular museum can be calculated with:

$A=l*w$

Where $l$ is the lenght and $w$ is the width.

You have that the lenght and the width in feet are:

$l=30\\w=10$

3. Let's call $x$ the width of the roped-off area. Then, the combined area is:

$A_c=l_c*w_c$

Where

$A_c=800$

$l_c=l+x+x=30+2x$

$w_c=w+x+x=10+2x$

4. Substitute values and simplify. Then:

$800=(30+2x)(10+2x)$

$800=300+60x+20x+4x^{2}\\4x^{2}+80x-500=0$

What expression is the simplified form of “-12+5a-a-6a+8a+8+3a”? Please explain your reasoning.

kramer

Combine like terms:

-12 + 5a - a - 6a + 8a + 8 + 3a

$-12 + 5a - a - 6a + 8a + 8 + 3a$

5a - a = 4a

4a - 6a = -2a

-2a + 8a = 6a

6a + 3a = 9a

-12 + 8 = -4

Answer

$9a - 4$
