Based on data from Bloodjournal.org, 10% of women 65 years of age and older have anemia, which is a deficiency of red blood cell
1 answer:
Answer:
the probability that the combined sample tests positive for anemia is ≈ 0,38.
Thus it is 38% likely that such a combined sample to test is positive.
Step-by-step explanation:
The combined sample tests positive if at least one of the 8 women has anemia.
Let p be the probability that a women 65 years of age and older have anemia
Then p=0.1
The probability that one of the 8 women has anemia and others does not is:
p× .
Since there are 8 combinations of this probability is possible, the probability that at least one of the 8 woman has anemia is:
8×p× =8×0.1×
≈ 0,3826

Step-by-step explanation:
Given is a polynomial in x
We have to find the remainder when the above polynomial is divided by x+5
Remainder theorem says that f(x) gives remainder R when divided by polynomial x-a means f(a) = R
Applying the above theorem we can say that value of the function when x =-5
= Remainder when f is divided by x+5
= F(-5)
Substitute the value of -5 in place of x
= (-5)^4 + 12(-5)^3 + 30(-5)^2 - 12(-5) + 70
= 625-1500+750+60+70
= 5
Hence answer is 5
Answer:
48:29
Step-by-step explanation:
So lets find the ratio without simplest form: the ratio is 96:58
When writing the ratio we write the one mention first
Now lets write it in simplest form practically reducing it to its lowest term
( we first write it as a fraction)
÷
=48:29
So the answer is 48:29
