Answer:
98.1% chance of being accepted
Step-by-step explanation:
Given:
sample size,n=56
acceptance condition= at most 2 batteries do not meet specifications
shipment size=7000
battery percentage in shipment that do not meet specification= 1%
Applying binomial distribution
<h3>P(x)=∑ᵇₐ=₀ (n!/a!(n-a)!)p^a (1-p)^(n-a)</h3>
In this formula, a is the acceptable number of defectives;
n is the sample size;
p is the fraction of defectives in the population.
Now putting the value
a= 2
n=56
p=0.01
=0.56960+0.32219+0.08949
After summation, we get 0.981 i.e. a 98.1% chance of being accepted. As this is such a high chance, we can expect many of the shipments like this to be accepted!
Victor writes 20 poems
<em><u>Solution:</u></em>
Given that victor writes 10 more poems than Ann
Also given that Ann writes 10 poems
To find: number of poems written by Victor
<em><u>From given information, we can frame a equation as:</u></em>
number of poems written by Victor = 10 more poems than Ann
number of poems written by Victor = 10 + number of poems written by Ann
Substituting the given , number of poems written by Ann = 10 , we get,
number of poems written by Victor = 10 + 10 = 20
Thus victor writes 20 poems
Answer:
replace x with number then multiply or divide
Step-by-step explanation:
it would equal the same mixed number. 5 2/3
Answer:
2i and -2i
Step-by-step explanation:
I'll change u to x to be easier to understand.
x^2 = -4
sqrt(x^2) = sqrt(-4)
sqrt(-4) = 2i, or -2i
