The quotient of 3 times a number "x" and 2 less 3 times the square of "x"​

Mathematics
1 answer:
Fofino [41]3 years ago
6 0

Three times a number x can be written as

3x

The quotien between this and 2 is

\dfrac{3x}{2}

from this, we will subtract something:

\dfrac{3x}{2}-\ldots

And this "something" is three times the square of x. The square of x is x^2, and three times this is 3x^2

So, our final expression is

\dfrac{3x}{2}-3x^2

Select all the correct equations.
Naya [18.7K]

Answer:

You did not post the options, but i will try to answer this in a general way.

Because we have two solutions, i know that we are talking about quadratic equations, of the form of:

0 = a*x^2 + b*x + c.

There are two easy ways to see if the solutions of this equation are real or not.

1) look at the graph, if the graph touches the x-axis, then we have real solutions (if the graph does not touch the x-axis, we have complex solutions).

2) look at the determinant.

The determinant of a quadratic equation is:

D = b^2 - 4*a*c.

if D > 0, we have two real solutions.

if D = 0, we have one real solution (or two real solutions that are equal)

if D < 0, we have two complex solutions.

In a certain game of chance, your chances of winning are 0.3. Assume outcomes are independent and that you will play the game fo
sergeinik [125]

Answer:

0.6517

Step-by-step explanation:

Given that in a certain game of chance, your chances of winning are 0.3.

We know that each game is independent of the other and hence probability of winning any game = 0.3 (constant)

Also there are only two outcomes

Let X be the number of games you win when you play 4 times

Then X is binomial with p = 0.3 and n =4

Required probability

= Probability that you win at most once

= P(X\leq 1)\\=P(X=0)+P(X=1)

We have as per binomial theorem

P(X=r) = nCr p^r (1-p)^{n-r}

Using the above the required prob

= 0.6517

Compare the weather on two different days using an inequality. Then see if their comparisons change by finding the absolute valu
dusya [7]

Inequalities are used to compare unequal expressions.

The actual comparison is:\mathbf{-3.5 < 5} or \mathbf{5 > -3.5}

The temperatures are given as:

\mathbf{Temperature =  -3.5F,\ \  5F,\ \  1.5F,\ \  -0.5F,\ \ -2F,\  \ 2.5F,\ \  -4F}

From the above list, we have:

\mathbf{Day \ 1=  -3.5F}

\mathbf{Day \ 2=  5F}

By comparison,

\mathbf{-3.5 < 5} or \mathbf{5 > -3.5}

Using absolute values, the inequalities are:

\mathbf{|-3.5| < |5|} or \mathbf{|5| > |-3.5|}

Hence, the actual comparison is:

\mathbf{-3.5 < 5} or \mathbf{5 > -3.5}
