A quadratic function is a function that has a degree of 2. This shows that there will be about 72 births for month 8
<h3>Quadratic functions</h3>
A quadratic function is a function that has a degree of 2. Given the quadratic function shown:
f(x) = x² + x
where
x is the total months
In order to use the function to predict the number of births for month 8, we will substitute x = 8 into the function as shown:
f(x) = x² + x
f(8) = 8² + 8
f(8) = 72 births
This shows that there will be about 72 births for month 8

Answer:
0.078125.
Step-by-step explanation:
This is a geometric sequence with first term a1 = 20 and common ratio r = 10/20 = 5/10 = 0.5.
nth term = a1 r^(n -1) so here:
9th term = 20(0.5)^(9-1)
= 20(0.5)^8
= 0.078125.
Answer:
B
Step-by-step explanation:
Answer: 0.195
Step-by-step explanation:
given data:
population = 2000 people.
people Who are over 6 feet tall = 389.
Solution:
the point estimate of people over 6feet tall
= no of people over 6 feet tall / total population size
= 389/2000
= 0.195
the point estimate of people over 6 feet tall is 0.195
