Y=34 if 18 times 2 is 36 minus 2

Answer:

x=18 and y=34

Step-by-step explanation:

y = 2x - 2; x = 18 (rewrite this)

x=18;y=2x−2

solve for x( x=18)

substitute 18 for any x in y=2x-2

y=2x-2

y=(2)(18)-2

y=34(simplify both sides of the equation)

sorry for the lengthy explanation i hope this helps, i hope you have a great day :) !!

Factor the expression. 12p + 60 [?1(p + [ D)

zhenek [66]

Answer:

$12p+60$ $= 12(p + 5)$

Step-by-step explanation:

Given

$12p+60$

Required

Factor

$12p+60$

Express $12p$ as $12 * p$ and $60$ as $12 * 5$

So, we have:

$12p+60$ $= 12 * p + 12 * 5$

Apply distributive property

$12p+60$ $= 12(p + 5)$

Before we use an applet to simulate the selection of random samples from this population, let’s make sure we are clear about who

Sauron [17]

Answer:

D) college students

The college students are best describes the population

Step-by-step explanation:

Explanation:-

Introduction:-

The outcome of a statistical experiment may be recorded either as a numerical value or as a descriptive representation.

Example:-

when a pair of dice are tossed and the sum of the numbers on the faces is the outcome of interest, we record a numerical value.

If the students of a certain school are given blood tests and the type of blood is of interest, we record a numerical value.

In particular study, the number of possible observations may be small, large but finite or infinite.

Example :- 1

In the classification of blood types we can only have as many observations as there are students in the school.

Therefore the results are finite number of observations.

Example :- 2

If we could toss a pair of dice indefinitely and record the sums occur, we would obtain an infinite set of values .

Population:-

The total of observations which we are concerned , whether this number is finite or infinite , this is called the population

The number of observations in the population is defined to be the size of the population.

Example :- If there are 600 students in the school that we classified according to blood group, we say that the population of size is 600.

Sample:- A sample is subset of a population

Therefore in given data

The college students are best describes the population

Female college students , part -time college students , and female part-time college students are samples it will come from population

What is the equation in standard form of a parabola that models the values in the table

shusha [124]

Answer:

Y=4x^2-3x+5

Step-by-step explanation:

For the standard form equation to model the values in the table, each value of x in the table should give the matching the y value when substituted into the equation. We will test each equation:

$Y=-4x^2+3x+5$ for (-1,12)

$Y=-4(-1)^2+3(-1)+5=-4(1)+-3+5=-4+-3+5=-2\\$

This does not give 12 as the answer and is not a solution.

$Y=-4x^2-3x+5$ for (-1,12)

$Y=-4(-1)^2-3(-1)+5=-4(1)+3+5=-4+3+5=4\\$

This does not give 12 as the answer and is not a solution.

$Y=3x^2-4x+5$ for (-1,12)

$Y=3(-1)^2-4(-1)+5=3(1)+4+5=3+4+5=12\\$

This does give 12 as the answer and is a possible solution.

We now try (2,15).

$Y=3(2)^2-4(2)+5=3(4)-8+5=12-8+5=9\\$

This does not give 15 as the answer and is not a possible solution.

$Y=4x^2-3x+5$ for (-1,12)

$Y=4(-1)^2-3(-1)+5=4(1)+3+5=4+3+5=12\\$

This does not give 12 as the answer and is not a solution.

We now try (2,15).

$Y=4(2)^2-3(2)+5=4(4)-6+5=16-6+5=15\\$

This does give 15 as the answer and is a solution.

This is the standard form of the equation.
