There will be 7 turkeys Xx
This is because:
52 divided by 2 = 26.
26 - 19 = 7.

Answer:
2.542
Step-by-step explanation:
Given the data :
Customer Pre-training Survey, x1 __Post-training Survey, x2 __ difference, d = (x2-x1)
A 6 8 2
B 5 5 0
C 10 10 0
D 7 10 3
E 6 8 2
F 5 6 1
G 2 8 6
This is a paired test as each subject has two different data values :
Difference in score, d :
dbar = Σd / n
dbar = (2+0+0+3+2+1+6) /
dbar = 14 / 7
dbar = 2
Standard deviation of d ; Sd = √[Σ(d - dbar)²/n-1]
Using calculator ; Sd = 2.082
Test statistic = dbar ÷ (Sd/√n)
Test statistic = 2 ÷ (2.082 / 7)
Test statistic = 2 ÷ 0.7869220
The statistic = 2.5415
Well, there are 60 minute in an hour and 60 seconds in a minute so we can multiply 7 by 60 and then 60 again to find out answer.
7 times 60=420 times 60=25200

Answer:
1507m²
Step-by-step explanation:
Given parameters:
Radius of cylinder = 12m
Height of cylinder = 8m
π = 3.14
Unknown:
Surface Area of cylinder = ?
Solution:
The surface area of any body is the sum of all the area that covers a body.
For a cylinder, the surface area is given as;
SA = 2πr² + 2πrh
Where SA = Surface Area
r = radius of cylinder
h = height of cylinder
Now input the parameters in the given equation and solve;
SA = (2 x 3.14 x 12²) + (2 x 3.14 x 12 x 8)
SA = 904.32 + 603.264
SA = 1507.584m² = 1507m²
Answer: option 2. x²-1
Step-by-step explanation:
concept to know: a²-b²=(a+b)(a-b)
------------
(a+b)(a-b)=a²+b²
(x+1)(x-1)=x²-1
