Consider a group of 1,000 newborn infants. one hundred (100) infants were born with serious birth defects, and 20 of these 100 died during the first year of life. ninety (90) of the 900 remaining infants without any birth defects also died during the first year of life. calculate the prevalence of serious defects in this population at the time of birth.

The prevalence of serious defects in this population at the time of birth is 10%.

Step-by-step explanation:

The prevalence of serious defects is the number of infants that were born with seriours birth defects divided by the total number of infants born.

In this problem, we have that:

There were 1000 newborn infants.

100 infants were born with serious birth defects.

Calculate the prevalence of serious defects in this population at the time of birth.

This is:

The prevalence of serious defects in this population at the time of birth is 10%.

since proposition states that a number is greater than 25, if is true then the number must actually be greater than 25.

this implies that all possible options, except 24, can be accepted

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
