A rectangular piece of sheet metal has a length that is 6 in. less than twice the width. a square piece 3 in. on a side is cut f
m_a_m_a [10]
The original width would be 19 and the original length would be 32.

Let w be the width.  Then 2w-6 would be the length.  However, after cutting a 3-inch square from each corner, both the width and length left over to fold into a box would be 6 inches smaller; thus the dimensions would be w-6 and 2w-6-6 or 2w-12.  

Since the section cut out is 3 inches long, 3 will be the height of the box.

Volume is found by multiplying the length, width and height of the box; thus we have:

1014=(w-6)(2w-12)(3)

We multiply the binomials and have:
1014 = [w*2w-12*w-6*2w-6(-12)](3)
1014 = (2w²-12w-12w+72)(3)
1014 = (2w²-24w+72)(3)
1014 = 6w² - 72w + 216

When solving a quadratic equation, we want it set equal to 0.  Subtract 1014 from each side:

1014-1014 = 6w² - 72w + 216 - 1014
0 = 6w² - 72w - 798

We will use the quadratic formula to solve this:

w=\frac{-b\pm \sqrt{b^2-4ac}}{2a}
\\
\\=\frac{--72\pm \sqrt{(-72)^2-4(6)(-798)}}{2(6)}
\\
\\=\frac{72\pm \sqrt{5184--19152}}{12}
\\
\\=\frac{72\pm \sqrt{5184+19152}}{12}
\\
\\=\frac{72\pm \sqrt{24336}}{12}
\\
\\=\frac{72\pm 156}{12}
\\
\\=\frac{72+156}{12} \text{ or } \frac{72-156}{12}
\\
\\=\frac{228}{12} \text{ or } \frac{-84}{12}=19 \text{ or } -7

Since we cannot have a negative number for a measurement, 19 has to be the width; then 2(19)-6 = 32 would be the length.

Scores on a university exam are Normally distributed with a mean of 78 and a standard deviation of 8. The professor teaching the
Triss [41]

Answer:

The percent of students who scored below 62 is 2.3%.

Step-by-step explanation:

In statistics, the 68–95–99.7 rule, also recognized as the empirical rule, is used to represent that 68.27%, 95.45% and 99.73% of the values of a Normally distributed data lie within one, two and three standard deviations of the mean, respectively.

Then,

  • P (-1 < Z < 1) ≈ 0.6827
  • P (-2 < Z < 2) ≈ 0.9545
  • P (3 < Z < 3) ≈ 0.9973

Given:

μ = 78

σ = 8

<em>X</em> = 62

Compute the distance between the value of <em>X</em> and <em>μ</em> as follows:

z=\frac{x-\mu}{\sigma}=\frac{62-78}{8}=-2

Use the relation P (-2 < Z < 2) ≈ 0.9545 to compute the value of P (Z < -2) as follows:

P(-2

The percentage is, 0.02275 × 100 = 2.275% ≈ 2.3%

Thus, the percent of students who scored below 62 is 2.3%.

Evaluate f^-2g for f = 3 and g = 27.<br> a) 1/3<br> b) 3<br> c) 9 ...?
maxonik [38]
If it is a negative exponent then that means it goes in the denominator and is raised to the power so if f = 3 then:f−2=1/(f2) = 1/9
if g = 27 then27/9 = 3So, the right option will be B.
