Answer:

p=1

Step-by-step explanation:

1) Figure out: -4(2p+5)=-8p-20

2) Simplify both sides: 3p+1=-8p+12

3)Subtract the 1: 3p=-8p+11

4)Add the 8p: 11p=11

5) Divide 11 by 11: p=1

Answer: p= 1

Step-by-step explanation:

Equation: 3p−6+7=32−4(2p+5) SOLVE FOR P.

Step 1. Simplify both sides of the equation.

3p−6+7=32−4(2p+5)

3p+−6+7=32+(−4)(2p)+(−4)(5)

(Distribute now)

3p+−6+7=32+−8p+−20

(Remember to combine like terms)

(3p)+(−6+7)=(−8p)+(32+−20)

3p+1=−8p+12

3p+1=−8p+12

Step 2. Add 8p to both sides of the equation.

3p+1+8p=−8p+12+8p

11p+1=12

Step 3. You have to subtract 1 from both sides.

11p+1−1=12−1

11p=11

Step 4. Divide both sides by 11.

11p /11= 11 /11

p=1

Final Answer:

p=1

Hope I could help! :)

A cruise ship is traveling at a speed of 20 knots . A knot is approximately equal to 1.151 miles per hour. What is the approxima
Mrrafil [7]
1 mile = 1760 yards
20 * 1.151 = 23.02
23.02 * 1760 = 40,515.2
40,515.2 / 60 = 675.243~
675.243~ / 60 = 11.2542~
They are traveling 11.25 yards per second
I took the number of knots multiplied by the approximate miles per hour equal
Then multiplied that by the number of yards in a mile, and then divided that by the number of minutes in an hour, and divided that by the number of seconds in a minute. That is how I got the answer, I hope it helps!

A Packaging Company produces boxes out of cardboard and has a specified weight of 16 oz. A random sample of 36 boxes yielded a s
user100 [1]

Answer:

The margin of error is of 0.73 oz.

The 99% confidence interval for the true mean weight of the boxes is between 14.57 oz and 16.03 oz. This means that we are 99% sure that the true mean weight of all boxed produced by the Packaging Company is between these two values, and that the specified weight is in this interval.

Step-by-step explanation:

We have that to find our \alpha level, that is the subtraction of 1 by the confidence interval divided by 2. So:

\alpha = \frac{1 - 0.99}{2} = 0.005

Now, we have to find z in the Ztable as such z has a pvalue of 1 - \alpha.

That is z with a pvalue of 1 - 0.005 = 0.995, so Z = 2.575.

Now, find the margin of error M as such

M = z\frac{\sigma}{\sqrt{n}}

In which \sigma is the standard deviation of the population and n is the size of the sample.

M = 2.575\frac{1.7}{\sqrt{36}} = 0.73

The margin of error is of 0.73 oz.

The lower end of the interval is the sample mean subtracted by M. So it is 15.3 - 0.73 = 14.57 oz.

The upper end of the interval is the sample mean added to M. So it is 15.3 + 0.73 = 16.03 oz.

The 99% confidence interval for the true mean weight of the boxes is between 14.57 oz and 16.03 oz. This means that we are 99% sure that the true mean weight of all boxed produced by the Packaging Company is between these two values, and that the specified weight is in this interval.

It takes a turtle 3 ¼ hours to walk 1 ½ miles. How many hours does it take to walk one mile?
Norma-Jean [14]

Answer:

It will take 6/13 hours to walk one mile

Step-by-step explanation:

Here, we want to calculate the number of hours it take to walk one mile

From the question, 1 1/2 miles take 3 1/4 hours

the number of hours it will take to walk 1 mile will be;

1 1/2 divided by 3 1/4

= 3/2 divided by 13/4

= 3/2 * 4/13 = 6/13 hours
