Answer:

No

Step-by-step explanation:

Length is the frequency density which is obtained by:

Frequency/width

Height is not proportional to width.

Frequency is proportional to the area of the rectangle

Answer:

No

Step-by-step explanation:

In different scenarios, the data will be different. However, sometimes, it's impossible to draw a histogram with equal widths, so in order to maintain clarity and fairness, the area of the bars should actually be proportional to the frequency, which is usually the y-axis of the graph or height of the bars.

Hope this helps!

The expression 7+3x+4 represents the perimeter of the triangle. Simplify the expression.
anyanavicka [17]

Answer:

-3.6

Step-by-step explanation:

Simplifying

7 + 3x + 4 = 0

Reorder the terms:

7 + 4 + 3x = 0

Combine like terms: 7 + 4 = 11

11 + 3x = 0

Solving

11 + 3x = 0

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-11' to each side of the equation.

11 + -11 + 3x = 0 + -11

Combine like terms: 11 + -11 = 0

0 + 3x = 0 + -11

3x = 0 + -11

Combine like terms: 0 + -11 = -11

3x = -11

Divide each side by '3'.

x = -3.666666667

Simplifying

x = -3.666666667

Part C Now try this one. Write a description of the partitioned function using known function types, including transformations.
Sever21 [200]

Answer:

Following are the function description to the given question:

Step-by-step explanation:

In the given-question, three functions are used, that can be defined as follows:  

In function 1:

This function is also known as the modulus on the absolute value function, for example:

f(x)=| x| \left \{ {{x , \ \ \ x>0} \atop {-x, \ \ \ \x

In the given in the above graph, that is f(x) = -x , \ \  x

In function 2:

In this function, It is an algebraic function that is y=x^2

It is also a part of the quadratic polynomial function, and its value is y=x^2 , \ \ \ x> 0  

In function 3:

In this function, it is the cubic polynomial equation that's value is y=x^3

In the graph its value is:

y=-x^3\\\\and \\ \\\to y= f(x) \\\\ \to y=-f(x)\\

A machine in a laboratory is set to steadily increase the temperature inside. The temperature in degrees Celsius inside the mach
vaieri [72.5K]

Answer:

1) f(3) means the temperature after 3 seconds

2) f(3) = 22 + 1.3(3) = 25.9

Temperature after 3 seconds is 25.9°C

3) f(t) = 35 means after t seconds, temperature was 35°C

4) 35 = 22 + 1.3t

1.3t = 13

t = 10 seconds
