Step-by-step explanation:
We have here a fraction. In this case, the <em>numerator</em> and the <em>denominator</em> of the fraction must be <em>cubed</em>, that is, both, the <em>numerator</em> and the <em>denominator</em> must be <em>raised</em> to the <em>same exponent</em>, in this case 3 (cubed).
In general, for fractions, this is the general rule that we must to follow to raise some fraction to any exponent.
In the case concerning this question, we have
So, the value of .
Answer:
5/24
Step-by-step explanation:
Start with the first part of the probelm 5/6 - 2/3
You need to find a common denominator of 6 and 3
common denominator= 6
so change 2/3 to 4/6
now you can subtract the top values
5/6-4/6
5-6=1
keep the denominator the same
= 1/6
Now divide 1/6 by 4/5
to divide you are going to multiply by the reciprocal so instead of 4/5 we are going to flip it to 5/4
1/6 x 5/4
5x1=5 and 6x4=24
= 5/24

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
Answer:
$14.50
Step-by-step explanation:
6 x $2.50 = $15.00
3 x $0.50 = $1.50
$15.00 + $1.50 = $16.50
$16.50 - $2.00 = $14.50
