The answer is A. Positive Weak Non-Linear

Step-by-step explanation:

The dotted points are graphed in an upward form which indicates that it's graphed positively but since the dotted points are scattered that indicates it has a weak "power".

Answer:

  $8.65×10^3

Step-by-step explanation:

The amount the West raised is the difference between the total and the sum of the other amounts raised. It is convenient to use a multiplier of 10^4 for each of the numbers, so the number for South can be rewritten as 0.675×10^4.

  West = 5.38×10^4 -1.46×10^4 -2.38×10^4 -0.675×10^4

  = (5.38 -1.46 -2.38 -0.675)×10^4

  = 0.865×10^4 = 8.65×10^3

West raised $8.65×10^3.

Answer: 0.72

Step-by-step explanation:

Given:  18 out of every 25 shoppers between the age of 18 and 34 research purchases online before going to a store.

Fraction of shoppers between the age of 18 and 34 research purchases online before going to a store [tex]=\dfrac{18}{25}[/tex]

In decimal , [tex]\dfrac{18}{25}=\dfrac{18}{25}\times\dfrac{4}{4}=\dfrac{72}{100}=0.72[/tex]

Hence, this value written as a decimal = 0.72

Step-by-step explanation:

To do this, you must notice that all of these are isosceles triangles (2 of the sides are the same.) You already have 1 value on each triangle, and the length of that side is the same length as the side with the unknown value, so those are the correct answers. If I made a mistake, please correct me. Everybody makes mistakes.

Answer:

1. 795, 23

2. 50, she will finish her candy on November 21 so she won't be able to share with her cousins

3. $276, 71 cars

Step-by-step explanation:

1. your equation: y = 35x + 235

plug in 16 to find how many pictures she will have on may 16: y = 35(16) + 235

you get y = 795

for the second part, you know are trying to find how long it will take to get to 1024 pictures, so you know your y, but you don't know your x

your equation: 1024 = 35x + 235

solve to get x = 22.54

this rounds up to 23, so your answer is 23

2. multiply 8 times 4 to get 32

subtract 32 from 82 to fin how many she has left

you get 50

for the second part, divide 82 by 4 to find how many day it will take to finish her candy

you get 20.5

so no, she will not have candy to share with her cousins, and she will finish her candy on November 21

3. for this, you have a negative y intercept since you need to make $24 to start profiting

your equation: y = 6x - 24

plug in 50 to x: y = 6(50) - 24

you get y = 276

so you make $276 with 50 cars

for the second part, plug in 400 to y: 400 = 6x - 24

solve to get x = 70.66

this rounds up to 71, so your answer is 71

-18w+2

Answer:

A

Step-by-step explanation:

6(-3w +1/3)

to distribute you multiply everything inside the parentheses by 6

so

6(-3w) + 6(1/3)

-18w + 6/3

-18w +2

Answer:

a = -5

Step-by-step explanation:

22 = 7 -3a

(subtract 7)

15 = -3a

(divide -3)

a = -5

OR

22 = 7 -3a

(add 3a)

3a + 22 = 7

(subract 22)

3a = -15

(divide 3)

a = -5

Answer:

slope of perpendicular line = -1/6

Step-by-step explanation:

Slope of Perpendicular line= -1/m

Compairing y=-6x+12 with the Standard equation of line y=-mx+c

Here m=6

So slope of Perpendicular line is: -1/6

Answer: 50%

Step-by-step explanation:

Let x = Total dishes.

Dishes from China = [tex]\dfrac38x[/tex]

Dishes from Japan  = [tex]12.5\% \text{ of }x= 0.125x[/tex]

Total dishes  from China and Japan = [tex]\dfrac38 x+0.125x=0.375x+0.125x=0.5x[/tex]

Dishes from other countries [tex]= x- 0.5x= 0.5x[/tex]

Percent of dishes from other countries= [tex]\dfrac{0.5x}{x}\times100\%= 50\%[/tex]

Hence, dishes from other countries = 50%

We want to find a line that is perpendicular to y = 1/6 and that passes through (-8, -2), that line will be x = -8.

So we want to get a line, we know it must be perpendicular to y = 1/6.

Notice that y = 1/6 is a horizontal line, then our line must be vertical, this means that our line is something like x = constant.

Now if we want our line to pass through the point (-8, -2), the constant must be equal to the x-value of the point, this is:

x = constant = -8

x = -8

This is the equation of the line perpendicular to y = 1/6 and that passes through (-8, -2)

Step-by-step explanation:

Answer:

The answer is below

Step-by-step explanation:

The volume of box = width * length * height

120 = x * x * y

120 = x²y

y=120/x²

The surface area (SA) = sum of the area of all faces side

SA = x² + x² + xy + xy + xy + xy

SA = 2x² + 4xy

substitute y =120/x²

SA = 2x² + 4x(120/x²)

SA = 2x² + 480/x

Taking the derivative:

SA' = 4x - 480/x²

making SA' = 0:

0 = 4x - 480/x²

480/x² = 4x

4x³ = 480

x³ = 120

x = 4.93 feet

y = 120 / x² = 120 / 4.93² = 4.93

Hence the width, length and height is 4.93 feet.

Answer:

Part A: Data set R

Part B: The correlation coefficient ranges from -1 to 1, where -1 represents a strong negative correlation and 1 represents a strong positive correlation. Data set R has a correlation coefficient of -.96, which has an absolute value that is closer to 1 than Data set Q's -.87, which means that it has a stronger linear relationship.

The data set R has a stronger linear relationship because the value of correlation coefficient is close to -1.

It is defined as the relation between two variables which is a quantitative type and gives an idea about the direction of these two variables.

[tex]\rm r = \dfrac{n(\sum xy)-(\sum x)(\sum y)}{\sqrt{{[n\sum x^2- (\sum x)^2]}}\sqrt{[n\sum y^2- (\sum y)^2]}}[/tex]

We have:

Correlation coefficient for data set Q = -0.87

Correlation coefficient for data set R = -0.96

The data set R has a stronger linear relationship because the value of correlation coefficient is -0.96 which is close to -1.

As we know the correlation coefficient varies between -1 to +1 when the value of correlation coefficient is close to -1 or +1 the relationship is strong.

Thus, the data set R has a stronger linear relationship because the value of correlation coefficient is close to -1.
