So you basically plot a point of the y axis on 7 then since the slope is -3x you have to go down 3 and to the right 1 and keep going then you have to do the same but opposite, go up 3 times and to the left 1 unit.

Find the arc length of the partial circle.

Bumek [7]

$\qquad\qquad\huge\underline{{\sf Answer}}♨$

As we know :

Length of arc = Radius × Angle made by Arc at center [ in radians ]

$\qquad \tt \dashrightarrow \: arc = radius \times angle \: \: ( in \: \: rad)$

$\qquad \tt \dashrightarrow \: arc = 8 \times \dfrac{ \pi}{2}$

$\qquad \tt \dashrightarrow \: arc = 4 \pi \dfrac{ }{} \: \: units$

$\qquad \tt \dashrightarrow \: arc = 4 \times 3.14 = 12.56 \: \: units\dfrac{ }{} \: \:$

The number of contaminating particles on a silicon wafer prior to a certain rinsing process was determined for each wafer in a s

Allushta [10]

Answer:

a) $P(X\geq 1) = 1-P(X$

b) $P(X\geq 5) = 1-P(X$

And replacing we got:

$P(X \geq 5) = 1-[0.01+0.02+0.03+0.12+0.11]=1-0.29=0.71$

Step-by-step explanation:

For this case we can solve this problem creating the following table

Number of particles Frequency Rel. Frequency

0 1 1/100 =0.01

1 2 2/100 =0.02

2 3 3/100=0.03

3 12 12/100=0.12

4 11 11/100=0.11

5 15 15/100=0.15

6 18 18/100=0.18

7 10 10/100=0.1

8 12 12/100=0.12

9 4 4/100=0.04

10 5 5/100=0.05

11 3 3/100=0.03

12 1 1/100=0.01

13 2 2/100=0.02

14 1 1/100=0.01

Total 100 1

We assume on this case the the relative frequency represent the probability.

Let X the number of contaminating particles on a silicon wafer

What proportion of the sampled wafers had at least one particle?

For this case we can use the complement rule like this:

$P(X\geq 1) = 1-P(X$

At least five particles?

Again for this case we can use the complement rule and we got:

$P(X\geq 5) = 1-P(X$

And replacing we got:

$P(X \geq 5) = 1-[0.01+0.02+0.03+0.12+0.11]=1-0.29=0.71$
