Convert it into standard form

Mathematics

Answer:

Option 1. y = 2x^{2} - 4x + 6

Step-by-step explanation:

To convert the equation into standard form, the first thing we have to do is FOIL the (x - 1)^2.

(x - 1)(x - 1) = x^{2} - 2x + 1

Now the function looks like: y = 2(x^{2} - 2x + 1) + 4

Now we have to distribute the 2 to everything inside the parentheses

2 * x^{2} = 2x^{2}     2 * -2x = -4x     2 * 1 = 2

Now the function looks like:  2x^{2} - 4x + 2 + 4

Combine like terms: 2x^{2} - 4x + 6

The function in standard form is 2x^2 - 4x + 6, or option 1

Dominik [7]
The answer to this question would be: D. <span>200>6P(8.00)+4S(5.00)
</span>

Michaela is planning a pizza party for 48 people and she uses 12-pack of soda and <span>8-slice pizza. That means the pack of soda she needs would be:
48 people/ (12soda/pack)= 4 pack

Then, number the pizza she needs:
48 people/ 8 (slice/pizza)=  6 pizza

She has $200 so the price she can afford should be lower than that. The function would be:
the money she has > number of pizza(price of pizza) + number of soda(price of soda)

Line CD contains points A (4, -7) and B (4, 8). The slope of line CD is
mylen [45]
<span>To find the slope, you divide the difference of the y-coordinates of a point on a line by the difference of the x-coordinates. It is expressed as:

slope = (y2 - y1) / (x2-x1)
slope = 8-(-7) / 4 - 4
slope = 15 / 0
slope = undefined <------ SECOND OPTION

The line should be vertical where the slope is undefined. Hope this answers the question. Have a nice day.</span>

A simple random sample of n measurements from a population is a subset of the population selected in a manner such that which of
Ierofanga [76]

Answer:

a) sample of size n from the population has an equal chance of being selected.

b) Every member of the population has an equal chance of being included in the sample.                                            

Step-by-step explanation:

Simple random sampling:

  • It is a type of probabilistic sampling.
  • It is an unbiased representation of population.
  • The probability of selection is equal for every observation.
  • A sample is taken in such a way that each member has an equal probability of being selected.
  • A simple random sample is a subset of a statistical population in which each member of the subset has an equal probability of being chosen.
  • Thus,the correct interpretation is given by,

a) sample of size n from the population has an equal chance of being selected.

b) Every member of the population has an equal chance of being included in the sample.

  • c) The simplest method of selection is used to create a representative sample.

The statement is false.

There is no pattern or technique used for selection. The selection is purely random.

  • d) Each subset of the population has an equal chance of being included in the sample.

The statement is false.

Each object of the population has an equal chance of being included in the sample. and not each subset.

  • e) Every sample of size n from the population has a proportionally weighted chance of being selected.

The given statement is false.
