Bayes Theorem Problem As part of general prenatal care in the US, pregnant women are routinely screened for the presence of a variety of genetic conditions in their unborn children using a method called Non-Invasive Prenatal Testing or NIPT. This method uses a blood test to gather the baby’s placental DNA that is present in the mother’s blood.
One condition that is routinely tested for in this way is Down Syndrome, which affects approximately 417 in every 100000 children. This test has been found to be 99.3% accurate in correctly detecting Down Syndrome and has a very low false positive rate of only 94 out of 100000 tests. (Source)

If a mother receives a positive result for Down Syndrome through NIPT, what is the probability that her child does not have Down Syndrome? Give your answer correctly rounded to three significant figures.

a_n = a_1 + (n - 1)d

the first term is 6.

the common difference d = ?

when you find d, replace n with 7 and d with the common difference to find your answer.

this excerpt is taken from the book “we shall not be moved : the women’s factory strike of 1909 “ and is written by joan dash. it is the story of the great strike when almost 30thousand women working in factories in america formed a union to fight unsafe working conditions, long working hours and miserable wages.

question: which best states the author’s purpose for including this information in the text?

answer: to challenge the reader’s ideas about a historical event

system of linear equation

step-by-step explanation:

as given in the data

a= 20 , b= -12

let us suppose that it is a straight line equation

now we know the formula for the system of linear equation

b= ma + c )

here m is slope of a straight line which is equal to formula

m=   (ii)

and here c is a constant

now putting the value of a and b in equation (ii)

m=

m=

putting the value of a,b and m in equation (i) gives us

-12 = + c

-12=-12 + c

adding 12 to both sides

-12 +12 = -12 +12 +c

0 =c

or c=0

as the value of the constant is zero which gives us that it is a linear equation and this order pair satisfies the system of linear equations.
