Answer:

$\dfrac{x^4y^4}{81}$

Step-by-step explanation:

$(\dfrac{3}{xy})^{-4} =$

$= (\dfrac{xy}{3})^{4}$

$= \dfrac{(xy)^4}{3^4}$

$= \dfrac{x^4y^4}{81}$

What is 82% of 525? Show work

True [87]

Answer:

430.5

Step-by-step explanation:

1. We assume, that the number 525 is 100% - because it's the output value of the task.

2. We assume, that x is the value we are looking for.

3. If 525 is 100%, so we can write it down as 525=100%.

4. We know, that x is 82% of the output value, so we can write it down as x=82%.

5. Now we have two simple equations:

1) 525=100%

2) x=82%

where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:

525/x=100%/82%

6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 82% of 525

525/x=100/82

(525/x)*x=(100/82)*x - we multiply both sides of the equation by x

525=1.219512195122*x - we divide both sides of the equation by (1.219512195122) to get x

525/1.219512195122=x

430.5=x

x=430.5

now we have:

82% of 525=430.5

Many fast-food restaurants have soft drink dispensers with preset amounts, so that when the operator merely pushes a button for

antiseptic1488 [7]

Answer:

Alternative hypothesis is that Worker productivity is higher with automatic dispensers.

The Rank for Group1 is 115.5 and Group 2 is 55.5.

Conclusion is that Worker productivity is higher with automatic dispensers.

Step-by-step explanation:

The null and alternative hypotheses are

H0: Group1 ≤ Group2 against the claim

Ha: Group1 > Group2

Alternative hypothesis is that Worker productivity is higher with automatic dispensers.

Calculations:

Group1 Group2

Sample Mean x ` 139.22 114.67

Sample size n 9 9

Sample SD 18.21 11.937

Rank 115.5 55.5

U 10.5 70.5

The Rank for Group1 is 115.5 and Group 2 is 55.5.

1. H0 hypothesis

As p-value < alpha and Z lies in the critical region, H0 is rejected.

The randomly selected value of Group1's population is considered have greater productivity than the randomly selected value of Group2's population.

2. P-value

The p-value equals 0.0046.

3. Test statistics

Z= u-μ+c/σ

The critical region for one tailed test for z at 0.01 significance level is

z > 2.33.

The test statistic Z equals 2.6063, which lies in the critical region of acceptance z> 2.326

4. Conclusion

As the calculated test statistic lies in the critical region H0 is rejected and it is concluded that

Worker productivity is higher with automatic dispensers.

Distance Formula: $d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Step-by-step explanation:

Step 1: Define

Point (-1/2, -8)

Point (-1/2, -2)

Step 2: Find distance d

Substitute: $d = \sqrt{(\frac{-1}{2} +\frac{1}{2} )^2+(-2+8)^2}$
Add: $d = \sqrt{(0)^2+(6)^2}$
Exponents: $d = \sqrt{0+36}$
Add: $d = \sqrt{36}$
Evaluate: $d = 6$
