The inequality to determine the number of packages Renna could remove from the elevator to meet the mass requirement is 620 - 37.4g = 450.

An inequality is simply used to show the relationship between the expressions that are not equal.

The mass limit is given as 450 grams. Renna has a package that has a weight of 620g.

Each package has 37.4g.

Let the number of packages to remove be p.

The expression will be:

= 620 - (37.4 × p) = 450

620 - 37.4g = 450.

This illustrates the concept of inequality.

Answer:

Surface area is the total area of the faces of a three-dimensional shape.

A square can not have a surface area since it's two dimensional. If you meant the area of a square then the formula is:

A = a²

a = length of side

8 in = 64 in

10 = 100 in

12 = 144 in

25

1) We must start by reminding the binomials. Since this question refers to a perfect square trinomial then we can write:

2) Now we can look at the expression. Let's start by dividing that 10 by 2, since we have to write that -10x as 2 times the product of x and the other term:

Note that the second term is 5²= 25

3) Hence, the answer is 25

For the graduation party, Nathan and Sydney should order  pieces of 70 fried chicken ,  11 pounds of meats  and 36 pounds of lasangnia .

In the question ,

it is given that

there are 15 drop in guests , and drop in guests are counted as half a guest .

So , the number of half guests = 15/2 = 7.5

number of guests for the party = 40 guests

So , total number of guests = 40+7.5 = 47.5

From the table , we can see that

19 party guests need 28 pieces of fried chicken .

So , 1 party guests will need 28/19 pieces of fried chicken .

so, 47.5 guests will need [tex]47.5*\frac{28}{19}[/tex] pieces of fried chicken

[tex]47.5*\frac{28}{19}[/tex] = 70

hence , 70 pieces of fried chicken is needed .

From the table , we can see that

19 party guests need [tex]4\frac{1}{3}[/tex] = 13/3 pounds of meats  .

so, 1 party guests will need 13/(3*19) pounds of meats .

So, 47.5 guests will need [tex]47.5*\frac{13}{3*19}[/tex] pounds of meats .

[tex]47.5*\frac{13}{3*19}[/tex] = 10.833

≈ 11

hence , 11 pounds of meats is needed .

From the table , we can see that

19 party guests need [tex]10\frac{3}{4}[/tex] = 43/3 pounds of lasangnia .

So , 1 party guests will need 43/(3*19) pounds of lasangnia .

So, 47.5 guests will need [tex]47.5*\frac{43}{3*19}[/tex] pounds of lasangnia .

[tex]47.5*\frac{43}{3*19}[/tex] = 35.8333

≈ 36

hence , 36 pounds of lasangnia is needed .

Therefore , For the graduation party Nathan and Sydney should order 70 pieces of fried chicken , 11 pounds of meats  and 36 pounds of lasangnia .

The margin of error is 0.88.

What is a margin of error?

In a random survey sample, a margin of error is a statistical measurement that takes into account the discrepancy between actual and anticipated findings.

Here, we have

Lower confidence interval = 21.42

Upper confidence interval = 23.18

Now,

Sample mean(x) = (Lower confidence interval + Upper confidence interval)/2

x = (21.42 + 23.18)/2

x = 44.6/2

Sample mean (x) = 22.3

Now, we find the margin of error,

margin of error = Upper confidence interval - x

= 23.18 - 22.3

= 0.88

         The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions.

        A formula for the question at hand is 2x minus 20 divided by 3 Equals 2x, or (2x - 20) /3 = 2x.

The difference in degrees over the last 24 hours is represented by x in this equation, which predicts temperature change.

We must find x in the given equation.

(2x - 20) /3 = 2x \s (2x - 20) = 3(2x) (2x) ...........(Multiply by 3 on both sides)

2x - 20 + 20 = 6x + 20 ...........(Add 20 to both sides)

2x - 6x = 6x + 20 - 6x ..........(Subtract 6x from both sides) (

-4x = 20 \s x = -5 ..........(Divide by - 4 on both sides)

The height of the barometer on Sunday = 34.8 inches

How is the barometer height on Sunday calculated?

Consider the barometer height for one week,

The average height of a barometer during one week = 30.84 inches

The total height of a barometer during one week = 30.84 * 7

                                                                                  = 215.88

Consider the barometer height for 6 weekdays,

The average height of a barometer for 6 weekdays of the same week= 30.18 inches

The total height of a barometer for 6 weekdays = 30.18 *6

                                                                                =181.08

The barometer height  on Sunday = One week height- 6 days height

The Sumerians were a southern Mesopotamian people whose civilisation flourished between approximately 4100 and 1750 BCE. Sumer was an ancient civilization that flourished in the Fertile Crescent region of Mesopotamia, between the Tigris and Euphrates rivers. Sumerians are regarded as the creators of civilisation as we know it today, according to their advancements in language, governance, building, and other fields.

They were able to take technologies produced elsewhere and use them on a far larger scale. This allowed them to mass-produce commodities such as textiles and pottery, which they could subsequently trade with others.

The slope for lot size is not different from 0.

We will let the slope of the size be β

So the hypothesis can be:  β = 0  (Null Hypothesis)  ,  β≠ 0 (Alternate Hypothesis)

If we consider a confidence level (the probability for which we can be confident that the null hypothesis is true) to be 95% (Probability = 0.95) then the level for which we are not confident that the null hypothesis is true will be (100 - 95)% = 5% (Probability = 0.05)

Thus, for this coefficient the P value is 0.5782.

As the p-value is more than the Probability for which we are not confident (0.05), so in this regard we can state then there is no such significance difference seen in this regard. Thus, we accept the null hypothesis here. This means that we can take the coefficient to be 0.

Brand A bags typically weigh more because the median of brand A is higher than that of brand B and is denoted as option A.

This is referred to as the middle value which separates the higher half from the lower half of a data or distribution. This is calculated by first ordering the numbers which could be from the lowest to highest or vice versa.

A data sample which has a higher figure as the median means that it has higher values present in the data distribution. This term provides an insight on certain properties of the values of the data which are given.

In this scenario, the median of brand A is higher than that of brand B which means that it has more weight and is therefore the reason why option A was chosen as the correct choice.
