Answer:3.38
Step-by-step explanation:
Count, N: 5
Sum, Σx: 18
Mean, μ: 3.6
Variance, σ2: 11.44
Steps
(10 - 3.6)2 + ... + (2 - 3.6)2
5
=
57.2
5
= 11.44
σ = √11.44
= 3.38
12 mins each
60 divided by 5 equals 12
Answer: 33.85 mm
Step-by-step explanation:
Use trigonometry, tan equation
You are give the tan angle and adjacent side, you need to find the opposite side so
O
T A
Tan(72)= x/11
x= tan(72) x 11
x= 33.85
Answer:
C' (4, - 6 )
Step-by-step explanation:
4 units left means subtracting 4 from the x- coordinate
3 units down means subtracting 3 from the y- coordinate
C (8, - 3 ) → C' (8 - 4, - 3 - 3 ) → C' (4, - 6 )
Answer:
2, 4, 4, 6
Step-by-step explanation:
So to get 3 to 2, you'd need to multiply by 2/3, so 2/3 would be the scale factor. 2/3*6=4, 9*2/3=6
