2 3
3 4.5
4 6
5 7.5

1.5
0.5
2
This is a trick question as this is not proportional.
None of the Above

Answers

Answer 1

Answer:

E (none of the above)

Step-by-step explanation:

1 = k(1.5)

2 = k(3)

Therefore, k = 2/3

and when we put k = 2/3 into all values in the table we notice it is right

but it could be "A" also if the relationship was cups of water to cups of rice

Suppose the y-intercept of a line is - 7 and the slope of the line is
-4/3
Which statement is true about the line?

A)The line falls from left to right.

B)The y-intercept is at (-7,0)

C)The equation of the line is y= 4/3x+7

D)The equation of the line is y= -4/3x+7

Answers

Answer:

A

Step-by-step explanation:

Since the slope is negative the line falls left to right.

The equation of the line falls from left to right.

What is a slope?

The slope of a line, commonly referred to as its gradient, in mathematics is a numerical representation of the steepness and direction of the line.

If a line passes through two points (x₁ ,y₁) and (x₂, y₂) ,

then the equation of line is

y - y₁ = (y₂- y₁) / (x₂ - x₁) x (x - x₁)

To find the slope;

m =  (y₂- y₁) / (x₂ - x₁)

Given, the y-intercept of a line is - 7 and the slope of the line is -4/3.

And the standard form of the slope-intercept form:

y = mx + b,

where m is the slope and b is the y-intercept.

Here, m = -4/3 and b = -7.

Substituting the above values to the standard slope-intercept form,

y = (-4/3)x + (-7)

y = (-4/3)x -7

And the line falls from left to right.

Therefore, the line falls from left to right.

hey. help pls and thank you​

Answers

I believe it is B. I did not look at the both the given points but one of the points that are unidentified and one of the given points:
(0, -8) and (2, -2)

To find slope use this equation:
(Y2 - Y1)/(X2 + X1)

Input the points into the equation:
(-2 - (-8))/(2 - 0) —> (-2 + 8)/(2 - 0)

You find that it becomes:

Angles A and B are complementary. Angle A measures 3x + 10
degrees and angle B measures 2x + 20 degrees. What is the value of
x?

Answers

Answer:

x = 12

Step-by-step explanation:

Lets set up the equation!

Complementary angles equal 90 degrees.

2x + 20 + 3x + 10 = 90

Now lets combine the like terms!

2x + 3x 20+ 10

5x +30 = 90

Now subtract 30 from both sides!

5x = 60

Divide each side by 5

x = 12

The scores on a standardized test are normally distributed. If a random sample of standardized test scores is taken and the confidence interval is (92.3,120.7), what is the sample mean x¯?

Answers

Answer: 106.5

Step-by-step explanation:

We know that, Confidence interval for population mean is given by :-

( Sample mean - Margin of error ,  Sample mean + Margin of error)

Given: confidence interval is (92.3, 120.7).

i.e.  Sample mean - Margin of error = 92.3   (i)

Sample mean + Margin of error = 120.7  (ii)

Adding (i) and (ii) , we get

2( Sample mean ) = 213

⇒ Sample mean = 106.5

Hence, the sample mean [tex](\overline{x})[/tex] = 106.5

Answers

Answer:

No solution.

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDASEquality Properties

Algebra I

Solving systems of equations using substitution/eliminationSolving systems of equations by graphing

Step-by-step explanation:

Step 1: Define systems

4x + 16y = -19

-2x - 8y = 10

Step 2: Rewrite systems

-2x - 8y = 10

Add 8y to both sides:                    -2x = 8y + 10Divide -2 on both sides:                x = -4y - 5

Step 3: Redefine systems

4x + 16y = -19

x = -4y - 5

Step 4: Solve for y

Substitution

Substitute in x:                         4(-4y - 5) + 16y = -19Distribute 4:                              -16y - 20 + 16y = -19Combine like terms:                -20 ≠ -19

Here we see that -20 does not equal -19.

∴ This systems of equations has no solution

Step 5: Graph

Check the systems.

Answers

Answer: y = 1/3x + 2

Step-by-step explanation:

You basically use the rise over run method and see the slope increases by 1/3 ( it comes up one and goes right 3 ) and it starts at 2

y = 1/3x + 2

Using Rise/Run — rise is the line rising, like going up, and run is the line running, like running to the side. It rises by 1, then runs by 3. That’s how you get 1/3x. Then, you find the Y variable, which is 2, and that it how you get the answer.

As part of a study of the association between smoking and risk of squamous cell carcinoma, a logistic regression model was estimated as:

logit(probability of having squamous cell carcinoma) = -4.84 + 4.6*(SMOKER)

where SMOKER=0 for non-smoker and 1 for smoker. What is the predicted probability of a smoker having squamous cell carcinoma?

Answers

Answer:

0.44

Step-by-step explanation:

Given the estimated logistic regression model on risk of having squamous cell carcinoma

-4.84 + 4.6*(SMOKER)

SMOKER = 0 (non-smoker) ; 1 (SMOKER)

What is the predicted probability of a smoker having squamous cell carcinoma?

exp(-4.84 + 4.6*(SMOKER)) / 1 + exp(-4.84 + 4.6*(SMOKER))

SMOKER = 1

exp(-4.84 + 4.6) / 1 + exp(-4.84 + 4.6)

exp^(-0.24) / (1 + exp^(-0.24))

Find the dimensions of a rectangle with area 729000 m2 whose perimeter is as small as possible. (Give your answers in increasing order, to the nearest meter.)

Answers

Step-by-step explanation:

Area of a rectangle = Length * Width

A = LW

729000 =  LW .... 1

Perimeter of a rectangle P = 2L+2W

P = 2L+2W

From 1;

W = 729000/L

P = 2L + 2(729000/L)

P = 2L + 1458000/L

To minimize the perimeter, dP/dL = 0

dP/dL = 2 -  1458000/L²

2 -  1458000/L² = 0

2L² - 1458000 = 0

2L² = 1458000

L² = 729000

L = √729000

Length = 853.8m

W = A/L

Width = 729000/853.8

Width = 853.8

Hence the dimension to the nearest meter is 854m by 854m
