Nathan is building a toolshed with a rectangular floor. The area of a rectangle is given by the formula l⋅w, where l represents

Pachacha [2.7K]

Answer:

Here, l is the length of the rectangle and w is the width of the rectangle

To Compare the values, you must calculate each given situation.

Area of a rectangle is equal to length times width.

i.e, $A = l \times w$

(A)

if l = 8 units and w= 6 units,

then;

$A = l \times w$ = $8 \times 6 = 48 unit^2$

(B)

if l =7 units and w = 7 units

$A = l \times w$ = $7 \times 7 = 49 unit^2$

Therefore, the Part B would yield a larger area.

If l -7 units and w = 7 units , the area of larger floor is 49 square units.

Simplifying Algebraic Expressions ; 7+9(-6+8)

Grace [21]

Start by multiplying the 9 out:

9(-6 + 8y) = -54 + 72y

Then, add the 7:

-54 + 72y + 7

Then simplify the whole thing:

-47 + 72y

how do you solve this problem. there are approximately 2.1 million deaths per year in country A. Express this quantity as deaths

slamgirl [31]

Well... we know that... there are 365 days in a year, unless is a leap-year, but we'll use 365 anyway

and each day has 24hrs, each hr has 60 minutes

so. let us use those ratios

$\bf 2.1million\iff 2.1E6\iff 2,100,000\qquad thus
\\\\\\
\cfrac{2100000\ deaths}{1\ year}\cdot \cfrac{1\ year}{365\ day}\cdot \cfrac{1\ day}{24\ hr}\cdot \cfrac{1\ hr}{60\ minute}$

so.. multiply and simplify, cancelling out any like-units atop and bottom

notice, all we do, is use the ratios, in a way, that if we need one unit to be changed, we flip the ratio

for example, to toss away "year" unit, since in the first fraction is at the bottom, then we put it on the top on the ratio, year/year = 1, effectively cancelling the unit

A linear regression was conducted on the number of cigarettes a person smokes in a day versus the number of times they cough in

makvit [3.9K]

Answer:

a) response variable

Step-by-step explanation:

The response variable is the variable that depends on other variables such as the independent or explanatory variable, it is the variable that is being tested. The response variable is also called the dependent variable.

In linear regression, the y variable is referred to as the response variable while the x variable is referred to as the explanatory or independent variable.

In this case the y variable is "the number of times they cough in a day" and this variation depends on the x variable "number of cigarettes a person smokes in a day".
