Step-by-step explanation:
each square is 1%
Solve both equations for x:
2x+7 = 3
2x = -4
x = -2
Plug x into the equation which contains b:
b(-2) -10 = -2
-2b = 8
b = -4
Answer:
b = -4
x = -2

Step-by-step explanation:
Answer:
3,3,4,6,6
4,4,5,6,7
5,5,6,6,8
Step-by-step explanation:
mode = n
median= n+1
mean = n+2
Range = n+3
let sets:
a,b,c,d,e
mode = n, at least two of them are the same and equal to n
n,n,c,d,e
median belong to the set, in ascending order:
n,n,n+1,d,e
which means d,e ≥ n+1, d≠e
mean is n+2
5(n+2)=n+n+n+1+d+e
2n+9=d+e
Assume e is the maximum:
Range is n+3:
e-n=n+3
e=2n+3
d=6≥n+1
n≤5,
Set is n,n,n+1,6,n+3
n+1≤6≤n+3
3≤n≤5
3,3,4,6,6 bimodal
4,4,5,6,7
5,5,6,6,8 bimodal
To find an average, add all the speeds of each arrow together and divide that number by the total number of arrows shot.
example:
Arrow 1:
20mph
Arrow 2:
23 mph
Arrow 3:
23 mph
= 20+23+23 = 66
66÷ 3= 22 mph on average
