(Laws of Exponents with Whole Number Exponents LC)
Karolina [17]

The given expression will be equal to ( 2.3 )¹⁵ / ( 0.9 )¹². The correct option is D.

<h3>What is an expression?</h3>

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given expression is 2.3 raised to the fifth power divided by 0.9 raised to the fourth power, all raised to the third power.

Write the expression in the mathematical form and solve:-

[ ( 2.9⁵) / ( 0.9 )⁴ ]³ = [ ( 2.9⁵) / ( 0.9 )⁴ ]³

                             =  [ ( 2.9 )¹⁵ / 0.9 )¹² ]

Therefore, the given expression will be equal to ( 2.3 )¹⁵ / ( 0.9 )¹². The correct option is D.

Tessa is cooking steak for her family. She wants to be sure the steak has an internal temperature of at least 160 degrees Fahren
Over [174]

Answer:

<u>Population : all the steaks Tessa can cook</u>

<u>Parameter : minimum internal temperature of 160 degrees Fahrenheit</u>

<u>Sample : two random thermometer readings</u>

<u>Statistic : minimum sample reading of 165 degrees Fahrenheit</u>

Step-by-step explanation:

Let's recall the definitions of these statistical concepts and match it with the information that were provided to us:

  • Populations can be the complete set of all similar items that exist, in our case, all the steaks that Tessa can cook.
  • Parameter is is a value that describes a characteristic of an entire population, such as the minimum temperature of the steaks Tessa is cooking in Fahrenheit degrees.
  • Sample is a subset of the population, in our case, the two random readings of the thermometer Tessa did.
  • Statistic is a characteristic of a sample, for our problem, it's the minimum reading of 165 degrees Fahrenheit.

Do you think it is easy to determine the solution set of a system of linear equations by graphing? Explain your answer.​
iogann1982 [59]

Answer:

Yes, if you keep all of this in mind... This all came from my lesson during class btw.

Step-by-step explanation:

Each shows two lines that make up a system of equations. If the graphs of the equations intersect, then there is one solution that is true for both equations. If the graphs of the equations do not intersect. Almost any situation where there is an unknown quantity can be represented by a linear equation, like figuring out income over time, calculating mileage rates, or predicting profit. Many people use linear equations every day, even if they do the calculations in their head without drawing a line graph. When both equations have the same slope, but not the same y-intercept, they'll be parallel to each other and no intersections means no solutions. When both equations have different slopes than regardless of the y-intercept they'll intersect for certain, therefore it has exactly one solution. The solution of such a system is the ordered pair that is a solution to both equations. To solve a system of linear equations graphically we graph both equations in the same coordinate system. The solution to the system will be in the point where the two lines intersect.
