The diagram shows the curve y=(1/2x-2)^6+5. Find the area of the shaded region.
Zepler [3.9K]
So the line that is the limit is where the equation crosses the y axis or where x=0

so
y=(1/2(0)-2)^2+5
y=(-2)^2+5
y=4+5
y=9
at y=9

the upper bound is y=9

alrighty

we will do
let's call the curve that is 6th degree f(x)
and the y=9, g(x)

f(x)=(1/2x-2)^6+5
g(x)=9

find where they intersect

9=(1/2x-2)^6+5
4=(1/2x-2)^6
fancy math
x=8

so the area under the curve will be
\int\limits^8_0 {g(x)-f(x)} \, dx because g(x) is above f(x)
so

\int\limits^8_0 {g(x)-f(x)} \, dx= \int\limits^8_0 {9-((\frac{1}{2}x-2)^6+5)} \, dx=
using our calculator because I can't figure out what \int\limits (\frac{1}{2}x-2)^6} \, dx is
\int\limits^8_0 {9-((\frac{1}{2}x-2)^6+5)} \, dx= \frac{64}{3} or about 21.33333333

Thirty percent (30%) of the bulbs in a large box are defective. If 12 bulbs are selected randomly from the box, calculate the pr
AleksandrR [38]

The probability that exactly 6 are defective is 0.0792.

Given:

30% of the bulbs in a large box are defective.

If 12 bulbs are selected randomly from the box.

To find:

The probability that exactly 6 are defective.​

Solution:

Probability of defective bulbs is:

p=30\%

p=\dfrac{30}{100}

p=0.3

Probability of non-defective bulbs is:

q=1-p

q=1-0.3

q=0.7

The probability that exactly 6 are defective is:

P(x=r)=^nC_rp^rq^{n-r}

P(x=6)=^{12}C_6(0.3)^6(0.7)^{12-6}

P(x=6)=924(0.3)^6(0.7)^{6}

P(x=6)=0.0792478958

P(x=6)\approx 0.0792

Therefore, the probability that exactly 6 are defective is 0.0792.

A​ 2.5-meter piece of framing lumber has been used to cut a piece 1.65 meters long. How much of the original piece of lumber​ re
mrs_skeptik [129]

Answer:

0.85 of the original piece of lumber remains.

Step-by-step explanation:

Well, this lumber piece of lumber started as 2.5 meters long. Then, a 1.65 meter piece was cut off of it. All we need to do is subtract.

2.5 - 1.65 =

2.50 - 1.65 = 0.85.

Therefore, 0.85 of the original piece of lumber remains.

Hope this helps! :)
