Answer:
ab - b^2
Step-by-step explanation:
The area of the large rectangle is
A = l*w
=a*b
The area of the unshaded region is
A = b*b = b^2
The area of the shaded region is the area of the rectangle minus the area of the unshaded region
ab - b^2
Evaluating a function means to plug the required value, substituting every x occurrence with that value.
So, you have
<span>Based on the data in the two-way table, the probability of being older than 25 years and having a hemoglobin level above 11 is
(154-69)/(429-139)
=85/290
=0.2931~0.29
Answer: A. 0.29
</span><span>The probability of having a hemoglobin level above 11 is
P(H>11)
=154/429
=0.35897~0.36
Answer: </span><span>C:0.36
</span><span>Being older than 25 years and having a hemoglobin level above 11
</span>Are not dependent on each other because w have not been told about any factors that were included in selection of sample.
