Answer:
B
Step-by-step explanation:
the frequency will change for each trial so a is wrong
b yea the probability should increase for either head or tail as the experiment progresses
c it will be impossible to get the frequency of head to equal the frequency of tails
d this is a 49/51 chance depending on what side did it flip on so while the frequency could increase the frequency could also decrease
the answer is B
I'm from your other question asking for help lmæo. and besides who flips that many coins
Answer:
6
Step-by-step explanation:
Given that the coordinate plane, three of the vertices of the rectangle are located at (-1.25, -0.25),
(-1.25, 0.25), and (1.25, 0.25)
The length L of the shape will be:
L = 0.25 - ( - 0.25 )
L = 0.25 + 0.25
L = 0.5
The width of the shape will be:
W = 1.25 - ( - 1.25)
W = 1.25 + 1.25
W = 2.5
Perimeter P = 2L + 2W
Substitute the Length and the width into the formula
P = 2(0.5) + 2(2.5)
P = 1 + 5
P = 6 metres
Therefore, the perimeter of the shape is 6 metres
Answer: Um, The answer is 1, 12, –3.
Step-by-step explanation:
Answer:
Option B.
2 × 3 interactions are possible.
Step-by-step explanation:
Since the experiment is manipulating room temperature, noise level, and room colour, this means that the experiment has 3 main effects, and for that reason has 3 independent variables.
Since there are 3 independent variables, there are 3! interactions.
And 3! = 3 × 2 × 1 = 2 × 3
