do the ratios form a proportion? Explain how you arrived at your answer. 9/6 and 156/104​

Answer:

See the attached image below for the filled out chart.

===================================================

Explanation:

Part 1

Pick any term and subtract off its previous term

So for instance 4.2 - 4.1 = 0.1

Or you could say 4.3-4.2 = 0.1

Whichever pair you pick, you should find that the common difference is 0.1

This means we add 0.1 to each term to get the next term. Therefore, the recursive rule is [tex]a_n = a_{n-1} + 0.1[/tex] which says "add 0.1 to the (n-1)th term to get the nth term". The (n-1)th term is the term just before the nth term.

The first term is [tex]a_1 = 4[/tex] as shown in the given sequence 4, 4.1, 4.2, ...

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

Part 2

We'll follow the same idea as part 1.

Subtract any two adjacent terms

-10-(-7) = -10+7 = -3

We add -3 to each term to get the next. This is the same as subtracting 3 from each term, which is reflected in [tex]a_n = a_{n-1}-3[/tex]

The first term is [tex]a_1 = -1[/tex]

Everything is summarized in the diagram below.

Answer:

P = 0.022

Step-by-step explanation:

Draw a normal distribution curve

Find the z score.

z score = 0.12

Find the probability for the z score.

P = 0.478

Subtract probability from 0.5

0.5 - 0.478 =0.022

Answer:

The x-intercept of the function is 13 which represents the number of hours until all the snow has melted.

Step-by-step explanation:

Since there were 0 inches of snow on the lawn after 13 hours, the x-intercept of 13 represents the number of hours after the storm stopped when all of the snow had melted away.

Have a good day :)

The x-intercept of the function is 13 which represents the number of hours until all the snow has melted.

A coordinate plane is a 2D plane that is formed by the intersection of two perpendicular lines known as the x-axis and y-axis. A coordinate system in geometry is a method for determining the positions of the points by using one or more numbers or coordinates.

Since there were 0 inches of snow on the lawn after 13 hours, the x-intercept of 13 represents the number of hours after the storm stopped when all of the snow had melted away.

Hence, the x-intercept is 13.

I think it is 0,2

Step-by-step explanation:

Because you need to substitute the ordered pairs into the linear equation:

so,

2(0)+3(2) = 6

             6=6

The two side, so equation are identical, so the correct answer is (0,2).

I hope this helps!

The solutions of 2x+ 3y= 6 are

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given:

2x+3y=6

Now, (2,3)

2x+3y=6

2(2)+ 3(3) = 4+ 9 =13

(2,3) is not solution

and, (0,2)

2(0)+ 3(2) = 0+ 6= 6

(0, 2) is a solution

and, (3, 0)

2(3)+ 3(0) =  6+0 = 6

(3, 0) is a solution

and, (3,-2)

2(3)+ 3(-2) = 6- 6=

(3, -2) is not solution

and, (6, -2)

2(6)+ 3(-2) = 12- 6= 6

(6, -2) is a solution

and, (0,6)

2(0)+ 3(6) = 17

Answer:

It depends if it is in a word problem or on a graph

Step-by-step explanation:

In a word problem you are looking for 2 numbers one that is a rate and one that is a beginning number. The rate is going to be the slope and the beginning number is going to be the y-intercept.

The equation is y=mx+b

The m is the slope and the b is the y-intercept

On a graph wherever the line crosses through the y-axis that is the y-intercept  or the b in the equation. To find the slope however is a little more difficult you have to rise over run it. This means that you find a point that is perfect or a (pretty point). Then you go up from the y-intercept to the x line that it is resting on and then you go over to that point.

In the equation provided the y-intercept is 3 or (0,3) and the slope is 1/4 so you go up 1 and over 4 and you would get your next point (4,4). Hope this helps.

so the linear equation is 20x+5y=400.

Answer:

14,400.00

You're going to take 40,000 multiplied by 7.2 which gives you the interest for one year. Multiply that by 5 to get through interest for 5 years.

The amount of interest that she gained after the maturity of the plan will be ₱14,400.

Simple interest is the concept that is used in many companies such as banking, finance, automobile, and so on.

I = (PRT)/100

Where I is the interest, P is the principal, R is the rate of interest, and T is the time.

Ms. Dorothy deposited ₱40,000 in a bank new plan paying 7.2% simple interest per annum if withdrawn after 5 years, otherwise, the plan will not apply.

Then the amount of interest that she gained after the maturity of the plan will be

I = (40,000 x 7.2 x 5) / 100

I = 400 x 7.2 x 5

I = ₱14,400

The amount of interest that she gained after the maturity of the plan will be ₱14,400.

Answer: The slope of the line can be determined from the gradient equation, rise (y axis)/ run (x-axis)

Hence let (-1, 8) be A and (2, -4) be B. The slope from A to B is (-4-8)/(2-(-1))= (-12)/3= -4

Check

2x+40 = 2×50 +40 = 140

x+90 = 50 +90 = 140 . . . . so the obtuse angles are congruent, as they should be

Answer:

-500

Step-by-step explanation:

Given sequence;

    97, 94, 91 ......

Unknown;

The 200th term of the sequence;

Solution:

Since we were given an arithmetic progression, we need to first find the common difference;

 Common difference  = second term - first term

                                     = 94 - 97  

                                     = -3

To find the 200th term, we use the expression below;

     Sn  = a + (n-1)d

   a is the first term

    n is the nth term

   d is the common difference

 S₂₀₀ = 97 + (200 - 1 ) x -3 = -500
