Answer:
A. Between 3.0 and 3.5 and between 4.0 and 4.5
Step-by-step explanation:
The zeroes of a function occur whenever a value of x returns zero. To predict where the zeroes lie, determine the interval(s) where the function crosses the x-axis. This occurs when either goes from a negative value to a positive value or vice versa.
From and , the y-values go from 4.0 (positive) to -0.2 (negative), respectively. Therefore, there must be a zero in this interval.
From and , the y-values go from -0.8 (negative) to 0.1 (positive), respectively. Therefore, there must also be a zero in this interval.
Thus, the zeros of this function occur between 3.0 and 3.5 and between 4.0 and 4.5, leading to answer choice A.
Answer:
Choice C
Step-by-step explanation:
Since every group has 111 people, and choice a and b talk about different group sizes, a and b are wrong.

Answer:
g = 14
Step-by-step explanation:
Using g = 14 we can do 14 x 3 to get 42. Then we can subtract 42 by 5 to get 37.
Answer:
m∠7 = 140º
Step-by-step explanation:
m∠4 = m∠2 + m∠3
120 = 80 + m∠3
m∠3 = 40
m∠3 + m∠7 = 180
40 + m∠7 = 180
m∠7 = 140º
