So the problem has no symbols, but we're going to multiply because the fraction on the left is right next to the parentheses.
-5/2 * 1/10x = -5x/20
I put "x" next to the 5 because the "x" counts as part of the numerator. Now that it's 5x over 20 that equals one, I'd first reduce -5x/20 into -x/4, then do
-x/4 * -4 = 1 * -4
To make the "x" side equal one, we have to multiply both sides by -4, to make both sides equal.
x = -4.
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
![\frac{56!}{0!\left(56-0\right)!}\left(0.01\right)^0\:\left(1-0.01\right)^{\left(56-0\right)} + \frac{56!}{1!\left(56-1\right)!}\left(0.01\right)^1\:\left(1-0.01\right)^{\left(56-1\right)} +](https://tex.z-dn.net/?f=%5Cfrac%7B56%21%7D%7B0%21%5Cleft%2856-0%5Cright%29%21%7D%5Cleft%280.01%5Cright%29%5E0%5C%3A%5Cleft%281-0.01%5Cright%29%5E%7B%5Cleft%2856-0%5Cright%29%7D%20%2B%20%5Cfrac%7B56%21%7D%7B1%21%5Cleft%2856-1%5Cright%29%21%7D%5Cleft%280.01%5Cright%29%5E1%5C%3A%5Cleft%281-0.01%5Cright%29%5E%7B%5Cleft%2856-1%5Cright%29%7D%20%2B)
![\:\frac{56!}{2!\left(56-2\right)!}\left(0.01\right)^2\:\left(1-0.01\right)^{\left(56-2\right)}](https://tex.z-dn.net/?f=%5C%3A%5Cfrac%7B56%21%7D%7B2%21%5Cleft%2856-2%5Cright%29%21%7D%5Cleft%280.01%5Cright%29%5E2%5C%3A%5Cleft%281-0.01%5Cright%29%5E%7B%5Cleft%2856-2%5Cright%29%7D)
=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!
Answer:
Presumably the first graph solely based on its shape.
Answer:
396
Step-by-step explanation:
it's it's 396 because if you add 99 more you will get 495.
each percentage is 99, so 99 x 5 is how many students there are 99 x 4 is the answer.
