Para resolver este problema se aplica la ecuación de la probabilidad, cuya ecuación es la que se presenta a continuación:

P = Nf/N * 100%

Los datos son los siguientes:

Nf = 1
N = 20

Sustituyendo los datos en la ecuación se tiene que la probabilidad es la siguiente:

P = 1/20 * 100%
P = 5%

La probabilidad de extraer el número que deseas en un intento es de 5%.

In order to solve for the variable in the equation 2 (x + 3) + 5 x = 3 (2 x minus 1), Jaleesa begins by applying the distributive property, then combines like terms. Which equation is the result of these steps?
7 x + 6 = 6 x minus 3
2 x + 6 + 5 x = 6 x minus 3
2 x + 3 + 5 x = 6 x minus 1
7 x + 3 = 6 x minus 1

Answers

Answer: 7 x + 6 = 6 x minus 3

Step-by-step explanation:

2 (x + 3) + 5 x = 3 (2 x minus 1)Now you distribute.2(x) + 2(3) = 2x+6And 3(2x) minus 3(1) = 6x minus 32x+6+5x = 6x minus 3Then combine like terms2x +5x=7x and there are no other like terms on either side of the equation.7x+6= 6x minus 3

A farmer wants to know the effect of using various amounts of fertilizer in relation to the yield of his crops. Be subdivided a portion of his land into 10 separate but essentially equal plots. He divided the land so that all of the plots had equal exposure to sun, rain, and other environmental conditions. He randomly selected 2 of the 10 plots and spread 2 pounds of fertilizer over each of them. Then he randomly selected 2 of the remaining plots and spread 3 pounds of fertilizer over each of them. He continued with the last sets of plots in the same manner, spreading 4, then 5, then 6 pounds of fertilizer over each of them. Below is a computer output for linear regression of amount of fertilizer versus yield for the 10 plots of land.

Predictor Coef SE Coef T P

What is the equation of the least squares regression line from this sample?

Answers

Answer:

The equation of line is

[tex]\text{yield}=1.15\times \text{fertilizer}+10.1[/tex]

Step-by-step explanation:

The general equation of line is given as

[tex]y=mx+b[/tex]

where

y is the dependent variable which is yield in this case.

x is the independent variable which is fertilizer in this case

m is the coefficient of the fertilizer whose value is 1.150 from the given values.

b is the constant whole value is 10.100 from the given values.

Thus the equation becomes.

[tex]\text{yield}=1.15\times \text{fertilizer}+10.1[/tex]

Answers

B. 4.5/t + 4.5/(2t) = 1

Step-by-step explanation:

Work = rate*timeMaria's rate = 6750/tJames's rate = 6750/2t

Their rate when working together:

6750/t + 6750/(2t) = 6750/4.5 ⇒ 1/t + 1/(2t) = 1/4.5 ⇒4.5/t + 4.5/(2t) = 1

Step-by-step explanation:

Given

See attachment

Required

Find b, c and d

First, we solve for b using:

[tex]b + 10 + b - 10 = 180[/tex] --- base angles of a parallelogram

Collect like terms

[tex]b + b =180+10-10[/tex]

[tex]2b = 180[/tex]

Solve for b

[tex]b = 180/2[/tex]

[tex]b = 90[/tex]

Then, we have:

[tex]d =b + 10[/tex]

[tex]c = b - 10[/tex] --- opposite angles

So, we have:

[tex]d =90 + 10[/tex]

[tex]d =100[/tex]

[tex]c = 90 - 10[/tex]

What is the theoretical probability that the spinner below will land on 6 if someone spins it 48 times?

Answers

Answer:

1/4 or 12*

Step-by-step explanation:

There are 8 possibilities.  2 of them are 6.

2/8=1/4

1/4 of 48 is 12

*The theoretical probability doesn’t change no matter how many times you spin the spinner.  It will always be 1/4.  (Or 0.25, or 25%). That could be what they’re asking.  If you spun it 48 times, it would probably land on a six 12 times.  That could also be what they’re asking for.  12:48 = 1:4.

Easy points: Is this a good paragraph for my biology class??The question was why is it important for soil to contain nitrogen, phosphorus, magnesium, and potassium.Soil is one of the main sources of nutrients needed by plants in order to grow. Nitrogen is used by plants for leaf growth and green color. Without nitrogen in the soil, the plant wouldnt grow tall and produce enough food.Phosphorus is used by plants to help form new roots, make seeds, fruit and flowers.This is crucial because crops take up phosphorus only from the soil solution.Potassium helps plants form strong stems and fast growth. It also increases disease resistance.It triggers activation of enzymes and is essential for production of ATP. Magnesium is the central core of the chlorophyll molecule in the plants tissue.
