Answer:
5/8
Step-by-step explanation:
First we need to figure out how many girls and boys there are.
g = girls
b = boys
g = b+8 ( eight more girls than boys)
b = g-8
There are 32 students)
g+b =32
Substitute b = g-8 into the equation
g + (g-8) = 32
Combine like terms.
2g-8 = 32
Add 8 to each side.
2g -8+8 = 32+ 8
2g = 40
Divide by 2
g = 20
There are 20 girls
The experimental probability of picking a girl is
girls/ total
20/32 = 5/8
The middle term of the simplified product is “x”.
The simplified product is x^2 - x - 12
X being the middle

Complementary: When two angles add up to 90 degrees
Supplementary: When two angles add up to 180 degrees
Similarities are both involve two angles, the difference is the total degrees they add up to.
Answer:
You only have four terms so n can only be 1, 2, 3 or 4!
I think you mean: What is the nth term of the sequence 15, 12, 9, 6, …?
The ellipsis (…) tells us that the sequence continues.
This is an arithmetic sequence, where the general term is: a+bn
n=1:a+b=15 [Eq. 1]
n=2:a+2b=12 [Eq. 2]
Subtracting Eq. 1 from Eq.2: b=−3
Substituting this into Eq. 1: a−3=15⇒a=18
Thus the nth term is: 18−3n
Step-by-step explanation:
HOPE THIS HELPS YOUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUU
Week one:
36 * 6.70 = $241.20
Week two:
40 * 6.85 = $274
Subtract:
274 - 241.20 = $32.80
Therefore, he made $32.80 more the second week then he did the first week.
Best of Luck!
