Answer:

non-proportional

Step-by-step explanation:

This equation is non-proportional. A proportional equation contains 2 variables where one is proportional to the other. An example would be:

y = 5x

Y is proportional to the value of X at a rate of 5. 5 is the "constant of variation", or the "constant of proportionality"

36 = 12d is not proportional because there is only one variable. That variable can be solved for, giving only one solution.

proportional:

"corresponding in size, degree or intensity"

"having the same or a constant ratio"

Answer:

here's what we know:

a + b = 72

a - b = 26

We can use the elimination method to solve this problem:

a + b = 72

a - b = 26

---------------

2a = 98

Divide both sides by 2:

a = 49

So we now have:

49 + b = 72

and:

49 - b = 26

Subtract 49 from both sides:

b = 23

and

-b = -23 (multiply both sides by -1) → b = 23

Step-by-step explanation:

A = 14°

Step-by-step explanation:

We can use sine law in this situation, where

[tex]\dfrac{\sin A}{a} =\dfrac{\sin B}{b}[/tex]

where a and b are the lengths of the sides opposite the corresponding angles. From the given diagram, we can see that

[tex]\dfrac{\sin A}{7\:\text{yd}} = \dfrac{\sin 75°}{28\:\text{yd}}[/tex]

or

[tex]\sin A = \dfrac{7}{28}\sin 75° = 0.241[/tex]

Solving for the angle A, we get

[tex]A = \sin^{-1}(0.241) = 14°[/tex]

Answer:

This is correct explanation

Step-by-step explanation:

A dividend is a number we want to divide by another number. It's supposed to be greater than 1000.

Quotient - the integer result of division. Remainder - well, what remains.

9/4 = 2, with remainder 1.

You want to find a number greater than 1000, which, when divided by another number, results in 37, with a remainder of 4.

I would multiply 37 by an increasing number until we get a product greater than 1000. This number is the one you are dividing by. Now add 4 to the product, so that when the sum is divided by the number you found we'll get a remainder of 4.

Answer:

B......................

Answer:

Step-by-step explanation:

To find x

Â= 180⁰-8x (angle on a straight line)

B= 180- 9x (angle on a straight line)

:. G + Â + B = 180⁰ ( sum of angles in a triangle)

5x + 180⁰ - 8x + 180⁰ - 9x = 180⁰

5x -8x - 9x + 180⁰ +180⁰ = 180⁰

-12x + 360⁰ = 180⁰

360⁰ - 180⁰ = 12x

180⁰ = 12x ( divide both sides by 12)

x = 15⁰

Hello, hope you are having a nice day.

This answer is not correct, because we can't add different variables. For instance, if we have 11x+2y, we can't add x's and y's together.

Therefore, the correct answer would be

11x+2y

Step-by-step explanation:

The first step is the answer, so you would have gotten 100% if you just left the question there. The next step, the second step, is quite right.

Answer:

H= 12, W=4

Step-by-step explanation:

let H = height

let H-8 = width

We know that the area of the rectangle is A = H*W

now we substitute the statements we have made:

H(H-8) = 48

H^2 - 8H - 48 = 0

Simplify:

(H-12)(H+4) = 0

So now we have 2 options H = -4 or H = 12, having a -ve number as height does not make sense so we use 12.

We know that width is H-8 so now we do 12-8 which is 4.

Therefore width is 4 and height is 12.

Step-by-step explanation:

Answer:

the height of the triangle is 6 inches and the base is 7 inches greater, or the base is 13 in

Step-by-step explanation:

The general area-of-a-triangle formula is A = (1/2)(base)(height), or  = (1/2)bh.

Here b = h + 7.

Applying the area formula given above:  A = 39 in^2 = (1/2)(h + 7)(h), or

78 in^2 = h^2 + 7h,

Rewriting this, in standard quadratic form, we get h^2 + 7h - 78 = 0

                                                                             -7 ± (49 - 4[1][-78])

Applying the quadratic formula to find h:   h = ----------------------------

                                                                                          2

           -7 ± (49 + 312)        -7 ± 19

or h = ----------------------- = ------------- = {-13, 6}

                      2                       2

Discard the negative 13 root; the height must be a positive quantity.

Thus, the height of the triangle is 6 inches and the base is 7 inches greater, or the base is 13 in

Answer:

The number of possible juries is C(30,12) = 30! / (30–12)! * 12! = 86,493,225. The number of possible all-female juries is C(16,12) = 16! / (16–12!) * 12! = 1820. So the probability of an all-female jury is 1820 / 86,493,225 = 0.0021%.

Step-by-step explanation:

Applying statistical concepts of multiplication of a variable by a constant, it is found that the mean of A is of $283, while the standard deviation is of $53.

When a constant is multiplied to each data in a variable:  

In this question, the variable has mean 28.3 and standard deviation of 5.3, and is multiplied by 10, hence:

[tex]28.3(10) = 283[/tex]

[tex]5.3(10) = 53[/tex]

The mean of A is of $283, while the standard deviation is of $53.
