The sum of a students three scores is 217. If the first is 30 points more than the the second, and the sum of the first two is 1

nekit [7.7K]

Answer:

First score is 90

Step-by-step explanation:

Let A represent the first score

Let B represent the second score

Let C represent the third score

A+B+C=217 equation 1

If the first score A is 30 points more than the second,B

A=B-30 equation 2

Lastly,sum of A&B is 16 more than 2C

A+B=2C+16 equation 3

From equation 1

A+B=217-C equation 4

substitute for A+B in equation 3

217-C=2C+16

217-16=2C+C

201=3C

C=67

substituting C in equation 4

A+B=217-67

A+B=150

if the first score more than the first,then the first 90 while second 60 since A+B=150

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:

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