Hope that was helpful for you! Good luck.
In 1 group there is 5 boys and 7girls
total students in 1 group: 7+5=12 students
now we know that there 12 students in 1 group. thus, we find how many groups of 12 are in 384384 students.
number of groups: 384384÷12=32032 groups
in each group we know we have 5 boys, so,
you multiply 5
32032×5=160160 boys
therefore, there is 160160 boys.
Answer:
Sum of Arithmetic Sequence
or 
Where:
- a = first term
- l = last term
- d = common difference
- n = number of terms
a = -3
l is unknown
d = 1 - -3 = 4
n = 40
Use the second equation because l in unknown.


Answer:
(a) .55
(b) .08
(c) about 42681 people
Step-by-step explanation:
Statistics!!
(a) .55 = point estimate
The point estimate is the middle of those two values, or the average. (.63+.47) / 2 = .55.
(b) .08 = ME
The margin of error is the difference between the point estimate and the outer values of the interval. .63-.55 = .08
(c) 42681 people
We think that .55 of the population want to add the bike lanes, so .55 * 75783 = 41680.65 ≈ 42681
