Answer:
B. The value is a parameter because the career at-bats of a baseball player are a population.
Step-by-step explanation:
The hitter had a career batting average of 0.366.
This value comes from information about the population of every time he has ever gone up to bat. Therefore, it is a parameter.
If on the other hand, we take the batting average of 5 games, the 5 games will be a sample and the batting average will be a statistic.
Answer:
16
Step-by-step explanation:
If n is number of nickles and d is number of dimes:
5n + 10d = 440
n = 3.5d
Substitute:
5(3.5)d + 10d = 440
17.5d + 10d = 440
27.5d = 440
d = 16
Answer:
y = 16, don't know if I'm 100% right but hope this helps.
Step-by-step explanation:
since they both equal Y they may be equal to each other
Then you would subtract 2x from both sides canceling it out on one side
2x + 8 = 5x - 4
-2x -2x
This would make the equation 8 = 3x - 4
next you add the 4 from both sides
8 = 3x - 4
+4 +4
This will leave you with 12 = 3x
now you divide 3 from both sides and 12/3 = 4 makes X = 4
next you take (4) and plug it in to one of the equations
y = 2(4) + 8
y = 8 + 8
y = 16
Maybe A because that’s in the middle but it does not show!
Answer:
Step-by-step explanation:
1) x - 21x = 5
x = x * 1
21x = x * 21
GCF = x
x - 21x = 5
x*(1 -21) = 5
x * (-20) = 5
-20x = 5
x =5/-20
x = -1/4
2) 6n² = 6 * n * n
30n = 6 * 5 * n
GCF = 6*n = 6n
6n² + 30n = 0
6n*(n + 5 ) = 0
6n = 0 or n + 5 = 0
n = 0 n = -5
n = 0 or -5
