The five posters made for spirit week are being hung in the front hall. What is the probability the largest poster will be in th
Leto [7]

Answer:

1/20 or 0.05

Step-by-step explanation:

Assuming that all five posters are different, the number of ways to randomly place those posters is given by:

N=5*4*3*2*1 = 120\ ways

If we want the largest to be in the center and the next largest to be on its left, two poster will have a set position and only three could be randomized:

n=3*2*1*1*1=6\ ways

Therefore, the probability is:

P=\frac{n}{N}=\frac{6}{120} =\frac{1}{20} =0.05

The probability is 1/20 or 0.05.

Let's go ahead and find the volume of a prism, then double the dimensions and see what happens to the volume. Then we can apply it to your volume.

volume of a prism with dimensions 2x2x2
v= 2x2x2 = 8 units^3

Now let's double it

volume of prism with dimensions 4x4x4
v= 4x4x4 = 64 units^3

So we see that by doubling the dimensions we multiply the volume by a factor of 8.  Let's do that for your volume, 3.5 m^3

3.5 x 8 = 28 m^3

To find the equation of a line, we need the slope of the line and a point on the line. Since we are requested to find the equati
Ad libitum [116K]

Answer:

m = \frac{1}{12}

Step-by-step explanation:

Given

(x,y) = (36,6)

f(x) = \sqrt x ----- the equation of the curve

Required

The slope of f(x)

The slope (m) is calculated using:

m = \lim_{h \to 0} \frac{f(a + h) - f(a)}{h}

(x,y) = (36,6) implies that:

a = 36; f(a) = 6

So, we have:

m = \lim_{h \to 0} \frac{f(a + h) - f(a)}{h}

m = \lim_{h \to 0} \frac{f(36 + h) - 6}{h}

If f(x) = \sqrt x; then:

f(36 + h) = \sqrt{36 + h}

So, we have:

m = \lim_{h \to 0} \frac{\sqrt{36 + h} - 6}{h}

Multiply by: \sqrt{36 + h} + 6

m = \lim_{h \to 0} \frac{(\sqrt{36 + h} - 6)(\sqrt{36 + h} + 6)}{h(\sqrt{36 + h} + 6)}

Expand the numerator

m = \lim_{h \to 0} \frac{36 + h - 36}{h(\sqrt{36 + h} + 6)}

Collect like terms

m = \lim_{h \to 0} \frac{36 - 36+ h }{h(\sqrt{36 + h} + 6)}

m = \lim_{h \to 0} \frac{h }{h(\sqrt{36 + h} + 6)}

Cancel out h

m = \lim_{h \to 0} \frac{1}{\sqrt{36 + h} + 6}

h \to 0 implies that we substitute 0 for h;

So, we have:

m = \frac{1}{\sqrt{36 + 0} + 6}

m = \frac{1}{\sqrt{36} + 6}

m = \frac{1}{6 + 6}

m = \frac{1}{12}

<em>Hence, the slope is 1/12</em>
