Answer:

  • a) y = 3/4x - 8
  • b) y = 1/7x + 7
  • c) y = -5/7x - 3
  • d) y = x + 8

Step-by-step explanation:

<u>Converting the equations from standard to slope-intercept form</u>

a)

  • 3x - 4y = 32
  • 4y = 3x - 32
  • y = 3/4x - 8

b)

  • x - 7y = -49
  • 7y = x + 49
  • y = 1/7x + 7

c)

  • 5x + 7y = -21
  • 7y = -5x - 21
  • y = -5/7x - 3

d)

  • x - y = -8
  • y = x + 8

A random number generator is used to create a list of 300 single-digit numbers. Of those 300 numbers, 146 are odd and 154 are ev
Archy [21]

Answer:

0.44

Step-by-step explanation:

The total numbers drawn = 300

Out those 146 are odd and 154 are even.

The number 8 was drawn = 22 times

So, the number of times an even number other than 8 = 154 -22 = 132

The experimental probability = The number of favorable outcomes ÷ The number of possible outcomes.

The experimental probability of an even number other than 8 being generated = \frac{132}{300}

Simplify the above fraction to decimal, we get

= 0.44

Therefore, the answer is 0.44

You would like to make a nutritious meal of eggs, edamame, and elbow macaroni. The meal should provide at least 40 g of carbohyd
Virty [35]

Answer:

Lets denote

1. eggs as x,

2. edamame as y

3. elbow macaroni as z

The problem then is

min TC=2x+5y+3z

subject to

2x+12y+43z \geq40\\17x+12y+8z\geq20\\14x+6y+z\leq50\\x\geq0\\y\geq0\\z\geq0

Step-by-step explanation:

First the objective is to minimize total cost subject to some nutritional requirements.

So the total cost function (TC) is the number of servings multiplied for the corresponding costs. Eggs cost 2, edamame 5, and macaroni 3

Next we have to meet the nutritional requirements, the first of the restrictions is the protein restriction. The problem requires that the meal contains at least 40g of carbohydrates (that is why the restriction is \geq 40). Then we add how much each meal component adds to the total, eggs add 2g of carbs, edamame 12g, and macaroni 43g.

Same for protein, we need at least 20 grams of protein (\geq 20). Eggs add 17g, edamame adds 12g, and macaroni adds 8g.

Finally we don't want more than 50 grams of fat (\leq50). Eggs add 14g, edamame add 6g and macaroni 1g.

Finally, we add the non negativity restrictions-> we cannot buy negative quantities of these goods, but we allow for zero.
