Is the data represented in the graph quantitative or qualitative? If it is quantitative, is it discrete or continuous?

Answer:

b.  quantitative, continuous

Step-by-step explanation:

Since here Dog = 0.07

Cat = 0.1

Snake = 0.12, and so on.

It is a numeric form So, it is <em>quantitative</em> data. And we can't count them(it include numbers between two natural number) so it is <em>Continuous</em> Variable.

The variable which is in numeric form is called Quantitative Variable. Example: Weight, Marks, etc.

And, the variable which we can't count is known as Qualitative Variable. Example: Smoking, Non- Smoking, etc.

Further Quantitative Variable can be divided into two parts:

  1. Continuous
  2. Discrete

The variable which we can count is known as the Discrete variable. It includes the natural numbers only. Example: Number of apples, Number of senior citizens in a particular area, etc.

The variable which we can't count is known as Continuous Variable. Example: Height, Weight, etc.

Answer:

Second point (-5/2, -7/2)

First point (3/2, 17/2)

Step-by-step explanation:

We have two equations, and we want to know at wich poin are equal. Hence, we have a system of equations and the solution is nothing more that the point (x,y) where those functions intercepts.

4x2+ 7x -11=y

3x+4=y

Lets use substitute method

4x2+7x-11=3x+4

This can be re arrange as the following eq:

4x2+4x-15=0

A quadratic equation, its solution can be obtained using the below eq.

x=\frac{-b+/- \sqrt{x^{2}-4ac } }{2a}

where a=4, b=4, c=-15.

Remember, the quadratic equation as a +/- sign, meaning that you will obtain one answer using the + operator and other using the - operator.

By doing the above, we have x=-5/2 and x=3/2

By using x=3/2 in equation of line (3x+4=y)  we have y=17/2

First point (3/2, 17/2)

By using x=-5/2 in equation of line (3x+4=y) we have y= -7/2

Second point (-5/2, -7/2)

Those points are the ones where the line and the parabola intercept.

2 3/8 - 4 1/2 + 3 1/8 - (1/2)
UkoKoshka [18]

let's convert the mixed fractions to improper fractions firstly.

\bf \stackrel{mixed}{2\frac{3}{8}}\implies \cfrac{2\cdot 8+3}{8}\implies \stackrel{improper}{\cfrac{19}{8}}~\hfill \stackrel{mixed}{4\frac{1}{2}}\implies \cfrac{4\cdot 2+1}{2}\implies \stackrel{improper}{\cfrac{9}{2}} \\\\\\ \stackrel{mixed}{3\frac{1}{8}}\implies \cfrac{3\cdot 8+1}{8}\implies \stackrel{improper}{\cfrac{25}{8}} \\\\[-0.35em] ~\dotfill

\bf \cfrac{19}{8}-\cfrac{9}{2}+\cfrac{25}{8}-\cfrac{1}{2}\implies \stackrel{\textit{using an LCD of 8}}{\cfrac{(1)19-(4)9+(1)25-(4)1}{8}}\implies \cfrac{19-36+25-4}{8} \\\\\\ \cfrac{4}{8}\implies \cfrac{1}{2}

An object in the shape of a rectangular prism has a length of 5 inches, a width of 3 inches, and a height of 2 inches. The objec
belka [17]

Answer:

4,080grams

Step-by-step explanation:

the formula for density is:

d=\frac{m}{V}

where d is density, m is mass, and V is volume.

solving for m in the last equation:

m=d*V

so if we find the volume and multiply it by the density d=8.3gr/cm^3  we will get the mass of the object.

The volume of a rectangular prism is given by:

V=l*w*h

where l is length, w is width and h is height:

l=5in\\w=3in\\h=2in

we substitute to find the volume:

V=5in*3in*2in\\V=30in^3

since the density has units of cm^3 we need the volume also in units of cm^3 , so we make the conversion using:

1in^3=16.3871cm^3

multiplying by 30:

30in^3=491.612cm^3

and now we find the mass with the equation:

m=d*V

substituting d and V:

m=(8.3gr/cm^3)(491.612cm^2)\\m=4,080.36gr

the nearest gram is: 4,080grams

What is 3(x-3)+5=3x+1+4
sergeinik [125]

Answer:

No solution

Step-by-step explanation:

3(x-3)+5=3x+1+4

3(x-3)+5=3x+5

3x-9+5=3x+5

3x-4=3x+5

   +4      +4

3x=3x+9

-3x   -3x

0≠9

Hope this helps!
