Answer:
10. 0.20
11. country
12. Hip-Hop and R&B, 3/10
13. Rock, 0.05
Step-by-step explanation:
10. for the boys, pop= 10% and country= 10%. add them together to get 20% and write that as a decimal, which is 0.20
11. 1/5 of 100% is 20%, and 20% of girls chose country as their favorite
12. Hip-Hop and R&B are the favorites for the most boys at 30% each. write that as a fraction of 100% which is 3/10
13. Rock is the least favorite among the girls at 5%, and 5% as a decimal is 0.05
I’ve broken it down into the parts that you’ve highlighted:
Part A:
x = 25 + y
x + y = 95
Part B:
I’m using the substitution method to find the amount of time that Eric plays volleyball, so:
x + y = 95
x = 95 - y
95 - y = 25 + y
70 = 2y
y = 35, 35 minutes spent playing volleyball
Part C: i don’t completely understand the question, perhaps there was a typo?
Answer:
Step-by-step explanation:
- We started at 1
- And it seems that index after index it multiplies by 3
- The formula for the geometric sequence defined implicitly is a(n) =a(1)r^(n-1)
Answer:
c. x+4
Step-by-step explanation:
A graph shows zeros to be -2, 1, 3, 4. This means the factors will be ...
(x +2)(x -1)(x -3)(x -4)
The factor (x+4) is not among the factors of the given expression.
Answer:
y = -7
Step-by-step explanation:
y2 - y1 / x2 - x1
-7 - (-7) / -2 - (-3)
0/1
= 0
y = 0x + b
-7 = 0(-2) + b
-7 = 0 + b
-7 = b
