Well, you would need to multiply 6.75 and 21, since there are 21 spools, you then simply subtract the spool used for the project and the is your answer, and don't forget to label
Actually, the real answer is "NO, BECAUSE GROUP B SHOULD BE THE CONTROL GROUP". Since Yvonne gave the flea medication to the group A, and we need a control group. If you don't know what it's the control group, it's the group that they don't put the experiment on, just to see if the group(s) being experimented, had any positive or negative changes. In a short summary they need group B to stay like they are to compare it to the experimented group (group A)
Good Luck!
Pythagoras’ theorem
a^2 + b^2 = c^2
Where a and b are two sides on a triangle and c is the hypotenuse.
Rearrange to find one to the sides that isn’t the hypotenuse.
a^2 = c^2 - b^2
a^2 = 25^2 - 10^2
a^2 = 625 - 100
a^2 = 525
(square root)
a = √525
= 5√21
We have that Probability of having 5 is
From the Question we are told that
The probability that 5 will come up at least once
Generally the equation for the is mathematically given as
The sample space is
n=12
Therefore Probability of having 5 is
