Hi there!
You would use open intervals.
In the given inequality, the "<" sign is used, which means "greater than".
Open intervals would be used unless the inequality uses "≤" or "≥", which
mean "equal to or greater/less than". Closed brackets would be used in this
instance.
Answer:
40% are girls
Step-by-step explanation:
60/150=0.4=40%
Answer:
4.63636363636 or 4.63 repeating
Step-by-step explanation:
If you do 51/11 you will get 4.63636363636 which is 4.63 repeating (sry I could not find the bar which indicates that it repeats)
Hope this helps

If a, b, c, d is geometric sequence, then

A. 5; 15; 25; 35

B. 5; 10; 25; 35

C. 6; 12; 18; 24

D. 7; 14; 21; 28

Answer: None of the sequences is a geometric series.
Given
W^2-W-12 = w^2+bW+c
b=-1,
c=-12
We look for m, n so that m+n=b=-1, m*n=c=-12, where m,n are integer factors of -12.
Now enumerate all possibilities for m*n=12
m n m*n m+n
1 -12 -12 -11
2 -6 -12 -4
3 -4 -12 -1 ....... so m*n=-12, m+n=-1
The factorization is then
W^2-W-12=(W+3)(W-4)
