Answer:
80000
Step-by-step explanation:
you multiply 2000x40 and get 80000 or you can do 8x10^4

Problem 7.43
A chemical plant superintendent orders a process readjustment (namely shutdown and setting change) whenever the pH of the final product falls below 6.92 or above 7.08. The sample pH is normally distributed with unknown mu and standard deviation 0.08. Determine the probability:
(a)
of readjusting (that is, the probability that the measurement is not in the acceptable region) when the process is operating as intended and
= 7.0 probability
(b)
of readjusting (that is, the probability that the measurement is not in the acceptable region) when the process is slightly off target, namely the mean pH is
= 7.02
Answer:
a
The value is
b
The value is
Step-by-step explanation:
From the question we are told that
The mean is
The standard deviation is 
Considering question a
Generally the probability of readjusting when the process is operating as intended and mu 7.0 is mathematically represented as

=> 
Generally

So
=>
=>
From the z table the probability of (Z < -1.25) and (Z > 1 ) is

and

So
=>
=>
Considering question b
Generally the probability of readjusting when the process is operating as intended and mu 7.02 is mathematically represented as

=> 
Generally

So
=>
=>
From the z table the probability of (Z < -1.5) and (Z > 0.75 ) is

and

So
=>
=>
Answer:
144º
Step-by-step explanation:
In a octagon there are 8 total sides. And the angles added up all together should equal 1080º.
136 + 132 + 129 + 116 + 158 + 141 + 124 = 936
1080 - 936 = 144
x = 144º
Answer:
Step-by-step explanation:
Let's reproduce the table.
Girls 10 10+5 = 15
Boys 8 8+5 = 13
No, the ratio of girls to boys would be different: 15 to 13 instead of 10 to 8.
<span>x2</span>+<span>y2</span>+6x+10y+9=<span>0
that is ur answer :)</span>
