Fast
Step-by-step explanation:
1/3 hour is 20 minutes
so that means it will take her 40 minutes to make the whole scarf.
Answer:
c. x=3
Step-by-step explanation:
4^x = 8^(x − 1)
4 = 2^2
8 = 2^3
2^2^x = 2^3^(x-1)
We know that a^b^c = a^(b*c)
2^(2x) = 2^(3*(x-1))
2^(2x) = 2^(3x-3)
The bases are the same so the exponents are the same
2x = 3x-3
Subtract 3x from each side
2x-3x = 3x-3-3x
-x = -3
x =3
Answer:
The mean and the standard deviation of the sampling distribution of the number of students who preferred to get out early are 0.533 and 0.82
Step-by-step explanation:
According to the given data we have the following:
Total sample of students= 150
80 students preferred to get out 10 minutes early
Therefore, the mean of the sampling distribution of the number of students who preferred to get out early is = 80/150 = 0.533
Therefore, standard deviation of the sampling distribution of the number of students who preferred to get out early= phat - p0/sqrt(p0(1-p)/)
= 0.533-0.5/sqrt(0.5*0.5/15))
= 0.816 = 0.82
