Answers

Answer 1

Answer:

no solutions

Step-by-step explanation:

plug in y to x:

15x + 5(8 - 3x) = 20

15x + 40 - 15x = 20 ( you would subtract 15x from 15x.)

0 + 40 = 20

40 = 20

40 does not equal 20 so it would be no solutions.

Answer 2

Using substitution, the system above has no solutions.

Given  that,

The equations are  15x + 5y = 20   and y = 8 ­– 3x.

Based on the above information, the calculation is as follows:

  Here we put the y value

15x + 5(8 - 3x) = 20

15x + 40 - 15x = 20  

0 + 40 = 20

40 = 20

Since 40 does not equal 20 so it would be no solutions.

(-8,4)

Step-by-step explanation:

System of Equations:

Solve the following system of equations by the substitution method:

5x - 6y = -64      [1]

y = 20 + 2x        [2]

Substituting y from [2] in [1]:

5x - 6(20 + 2x) = -64

Operating:

5x - 120 - 12x = -64

Simplifying:

-7x - 120 = -64

Adding 120:

-7x = -64 + 120 = 56

x = 56/(-7) = -8

x = -8

From [2]:

y = 20 + 2(-8) = 4

Solution (-8,4)

[tex]x = \sqrt{y}[/tex]

Step-by-step explanation:

[tex]x^{3/4 } = y^{3/8 }[/tex]

Note that

[tex]x^{3/4 } = \sqrt[4]{x^3}[/tex]

[tex]y^{3/8 } = \sqrt[8]{y^3}[/tex]

So,

[tex]\sqrt[4]{x^3} = \sqrt[8]{y^3}[/tex]

[tex]( \sqrt[4]{x^3} ) ^8= ( \sqrt[8]{y^3} )^8[/tex]

[tex]( \sqrt[4]{x^3} ) ^8= y^3[/tex]

Once

[tex]( \sqrt[4]{x^3} )^8 = (( \sqrt[4]{x^3} )^4)^2= (x^3)^2 = x^6[/tex]

[tex]x^6 = y^3[/tex]

[tex]x = \sqrt[6]{y^3}[/tex]

[tex]x = y^{3\cdot 1/6}[/tex]

[tex]x = y^{1/2}[/tex]

[tex]x = \sqrt{y}[/tex]

The weights of bags of grasecks chocolate candies are normally distributed with a mean of 4.3 ounces and a standard deviation of 0.05 ounces what is the probability that a bag of these chocolate candies weighs less than 4.27 ounces

Answers

Answer: 0.2743

Step-by-step explanation:

Let X be a random variable that represents the weight of bags of grasecks chocolate candoes.

X that follows normal distribution with, Mean = 4.3 ounces, Standard devaition = 0.05 ounces

The probability that a bag of these chocolate candies weighs less than 4.27 ounces :[tex]P(X<4.27) =P(\dfrac{x-\mu}{\sigma}<\dfrac{4.27-4.3}{0.05})[/tex]

[tex]=P(z<-0.6)\ \ \ z=\dfrac{x-\mu}{\sigma}]\\\\=1-P(Z<0.6)\\\\=1-0.7257\ [\text{ By p-value table}]\\\\=0.2743[/tex]

Hence, the required probability = 0.2743

The probability that a bag of these chocolate candies weighs less than 4.27 ounces is 0.2743

What is probability?

Probability is defined as the ratio of the number of favourable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.

Let X be a random variable that represents the weight of bags of grasses chocolate candies.

X that follows normal distribution with, Mean = 4.3 ounces, Standard devaition = 0.05 ounces

The probability that a bag of these chocolate candies weighs less than 4.27 ounces :

[tex]P(x < 4.27)=P[\dfrac{x-\mu}{\sigma} < \dfrac{4.27-4.3}{0.05}[/tex]

P ( x < 4.27 )   =   P (  z < -0.6  )

P (  x < 4.27  )  =  1  -  P (  z < -0.6 )

P ( x < 4.27 )   =   1  -  0.7257

P ( x < 4.27 )   =  0.2743

Hence,the probability that a bag of these chocolate candies weighs less than 4.27 ounces is 0.2743

Designing a video game takes tons of creativity. What inspires your personal creativity and ideas for video games? Explain and give several specific examples. How do you make sure your ideas are original and not copied directly from other video games? Explain.

What inspires my personal creativity is all the indie games I have played in the past, and they have always amazed me with their design, video games have always been a part of me from the Mario games I played when I was little to AAA titles. My ideas are original because I’ve seen so much, that I know when something is unique and original.

Every 10 levels is a new sport and each level is harder, but at the end of each level you earn money to buy better gear, (like a system from simple rpg,) but if you lose, you also lose money. Also, you would need to use feedback that you would get from players to improve the game.

Simplify the second part of the left side.
