Answer:
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%.
Answer:
Ivan’s range: 2,640 = 2.64 x 10^3 ft
Winnies
range: (2.5)5280 = 13200 = 1.32 x 10^4 ft
Winnies WiFi has the greater range
<span>To solve the problem, to 40%
of the total customer should be solve. And this can be solve by muliplting it
by the fraction (0.4). so 140 x 0.4 = 56 customers. Since Trudy has already 60
of her sutomers job ready then she met her target.</span>
For this case what we must do is find a quadratic function that is already factored.
This is because in the factored quadratic equations, it is easier to observe the zeros of the function.
In this case, the zeros of the function represent the time at which the company did not make any profit.
We have the following equation:
p (t) = 40 (t - 3) (t + 2) (t - 5) (t + 3)
We observed that there was no gain in:
t = 3
t = 5
The other roots are discarded because they are negative
Answer:
a.p (t) = 40 (t - 3) (t + 2) (t - 5) (t + 3)
