The yield of corn in bushels per acre and the amount of rain in the growing season.

Identify the explanatory variable and the response variable, if possible.

1. Amount of rain is the explanatory variable and yield of corn is the response variable.

2. Bushels per acre is the explanatory variable and amount of rain is the response variable.

3. Yield of corn is the explanatory variable and amount of rain is the response variable.

4. Amount of rain is the explanatory variable and bushels per acre is the response variable.

5. Rain is the explanatory variable and corn is the response variable.

Answers

Answer:

1. Amount of rain is the explanatory variable and yield of corn is the response variable.

Step-by-step explanation:

Explanatory Variable is the causal variable, which effects the other variable.

Response Variable is the resultant variable, which is effected by the other variable.

In this case, amount of rain effects the yield of corn (bushels per acre).

So, Amount of rain being causal effecting variable - is Explanatory Variable. Corn yield, being resultantly effected variable - is Response Variable.

how to solve 2x^2-11x+12=0

Answers

Answer:

x= 3/2   and  4

Step-by-step explanation:

Use this method to solve;

First get the multiples of   12:    -1, -12   -2, -6    -3, -4 (we use negatives, because we need a positive 12, and a negative 11).

Next, set it up like this:  (2x - )   (x-  ).

Then plug in (2x-3)  and (x -4), and use rainbow to double check.

Then take 2x-3=0    and   x -4 =0 to get x.

2x-3=0, add 3 to both sides, leaving you with 2x=3, then divide by 2 to get x alone which leaves x= 3/2, could use 1.5 or 1 (1/2) too.

Then do the same with x-4=0, add 4 to both sides leaving x= 4.

Answers are x= 3/2   and 4.

Una persona ahora en el banco 1000 pesos, el cual le ofrece un interés fijo de 3%. La función que relaciona el dinero ahorrado que recibirá después de x meses de ahorro

Answers

Answer:

Interes= [Principal*(1+tasa de interes)^x] - Principal

Step-by-step explanation:

Dada la siguiente información:

Principal= $1,000

Tasa de interes= 3% anual = (0.03/12)= 0.0025 mensual

Número de periodos= x

Para calcular el interés ganado, hay que usa la formula siguiente:

Interes= [Principal*(1+tasa de interes)^x] - Principal

Por ejemplo, para 6 meses:

Interes= [1,000*(1.0025^6)] - 1,000

Interes= $15.09

6. A farmer sows a certain crop. It costs $240,000 to buy the seed, prepare the ground, and sow the crop. In one year's time it will cost $93,200 to harvest the crop. If the crop will be worth $350,000, and the interest rate is 7%, what is the net present value (NPV) of this investment?

Answers

Answer:

$0

Step-by-step explanation:

Given that:

Preparation and sowing cost = $240,000

Cost of harvest after a year = $93,200

Worth of crop = $350,000

Interest rate (r) = 7% = 0.07

Net present value of Investment :

[(worth - Cost after 1 year) / (1 + r)] - initial investment cost

[(350,000 - 93,200) ÷ (1 + 0.07)] - 240,000

[256,800 / 1.07] - 240,000

$240,000 - $240,000

= $0

b. For every year the car value decreases $1,221.

c. $11,273

Step-by-step explanation:

a. (y2-y1)/ (x2-x1)

(16157-17378)/(3-2)= -1221

For the y-intercept you would just add 1221 twice to the value of the 2 year old car, get the value of 0 years.

c. -1221(7) +19820 =$11,273

For what values of m are there 2 different distinct real solutions? Give your answer as an inequality. X^2-2x+m.

I'm not sure, but I think the formula is b^2-4ac>0​

Answers

Answer:

m<1

Step-by-step explanation:

If the expression is in the form of [tex]ax^2+bx+c[/tex], then the condition for having 2 different real roots is

[tex]b^2-4ac>0\cdots(i)[/tex].

The given expression is [tex]x^2-2x+m[/tex].

Here, a=1, b=-2 and c=m.

So, by using equation (i),

[tex](-2)^2-4(1)(m)>0[/tex]

[tex]\Rightarrow 4-4m>0[/tex]

[tex]\Rightarrow 4m<4[/tex]

[tex]\Rightarrow m<4/4[/tex]

[tex]\Rightarrow m<1[/tex].

Hence, the condition for the expression [tex]x^2-2x+m[/tex] to have two different real roots is m<1.

In ARST, mZR = (5x – 11)", mZS = (3x – 3)°, and m_T = (3x + 18)º.
Find mZR.

Answers

Answer:

m∠R = 69

Step-by-step explanation:

m∠R + m∠S + m∠T = 180       {Angle sum property of triangle}

5x - 11 + 3x - 3 +  3x + 18 = 180

5x + 3x + 3x - 11 - 3 + 18 = 180     {Combine like terms}

                     11x  +4      = 180

                                 11x = 180 - 4

                                 11x = 176

                                    x = 176/11

x = 16

m∠R = 5x - 11

        = 5*16 - 11

        = 80 - 11

m∠R = 69
