Answer:Perimeter is the limit of any given geometric figure. Circumference is just the name given to a circle’s perimeter, in other words, the circle’s limit, its edge.

The reason for this is because the perimeter is, by definition, the sum of the lenghth of every side of any given geometric figure. A circle has either no sides, or number of sides, so its perimeter has to be treated differently.

Remember that π (Pi) equals 3.141592 approximately. This is a constant, meaning that no matter what circle you are studying, Pi will always have the same value. It is the relation between the diameter and the lenght of its circumference. A circle with diameter xwill travel 3.141592x before it completes a revolution. This is where Pi comes from.

So the difference would be that a “normal” perimeter is only the sum of the sides. A circumference is the perimeter of a circle, given a diameter and the constant value of Pi, that derives from other properties of the circle, and not by its sides (remember a circle has either none or nnumber of sides).

Perimeter is for a geometric shape (square, triangle, diamond, rectangle,etc.), whereas circumference is the “perimeter” of a circle

A wholesale distributor of packaged nuts sells two different mixes of peanuts and cashews, mix A and mix B. Each package of mix
Tom [10]

Answer:

The answer is below

Step-by-step explanation:

Let x represent the number of packages of mix A nuts and let y represent the number of packages of mix B nuts

Since 8 ounces (oz.) of peanuts is used to produce a package of mix A and 6 ounces (oz.) of peanuts is used to produce a package of mix B. Also, No more than 120 oz. of peanuts can be used each day. This can be represented by the inequality:

8x + 6y ≤ 120             (1)

4 ounces (oz.) of cashew is used to produce a package of mix A and 6 ounces (oz.) of cashew is used to produce a package of mix B. Also, No more than 96 oz. of peanuts can be used each day. This can be represented by the inequality:

4x + 6y ≤ 96            (2)

The inequality from equation 1 and equation 2 is graphed using geogebra online graphing.

If x, y ≥ 0, the solution to the problem is:

(0, 0), (0, 16), (15,0), (6, 12)

the ratio of red ribbons to green ribbons is 4 to 6 if there a total of 32 red ribbons then how many green ribbons are there?
melomori [17]

There are 48 green ribbons

<h3><u>Solution:</u></h3>

Given that the ratio of red ribbons to green ribbons is 4 to 6

Which can be written in following way:-

\frac{\text {Red} r i b b o n}{\text {Green ribbon}}=\frac{4}{6}

There are total number of 32 red ribbons

We have to determine the number of green ribbon

Let the number of green ribbon be ‘6a’

And number of red ribbons be "4a"

Given number of red ribbons = 32

4a = 32

a = 8

number of green ribbon = 6a = 6(8) = 48

Therefore number of green ribbons is 48

A newsgroup is interested in constructing a 90% confidence interval for the proportion of all Americans who are in favor of a ne
Evgen [1.6K]

Answer:

a. With 90% confidence the proportion of all Americans who favor the new Green initiative is between 0.6290 and 0.6948.

b. If the sample size is changed, the confidence interval changes as the standard error depends on sample size.

About 90% percent of these confidence intervals will contain the true population proportion of Americans who favor the Green initiative and about 10% percent will not contain the true population proportion.

Step-by-step explanation:

We have to calculate a 90% confidence interval for the proportion.

The sample proportion is p=0.6619.

p=X/n=370/559=0.6619

The standard error of the proportion is:

\sigma_p=\sqrt{\dfrac{p(1-p)}{n}}=\sqrt{\dfrac{0.6619*0.3381}{559}}\\\\\\ \sigma_p=\sqrt{0.0004}=0.02

The critical z-value for a 90% confidence interval is z=1.6449.

The margin of error (MOE) can be calculated as:

MOE=z\cdot \sigma_p=1.6449 \cdot 0.02=0.0329

Then, the lower and upper bounds of the confidence interval are:

LL=p-z \cdot \sigma_p = 0.6619-0.0329=0.6290\\\\UL=p+z \cdot \sigma_p = 0.6619+0.0329=0.6948

The 90% confidence interval for the population proportion is (0.6290, 0.6948).
