. Which category(s) does 75% belong? I. Real II. Whole III.Rational IV. Integer V. Irrational VI. Natural * A. III and IV only B

kifflom [539]

Answer: B.) 1 and 111 only.

Step-by-step explanation:

75% = 75/100 = 0.75

0.75 falls into the category of rational numbers. Rational numbers comprises of numbers which can be expressed in the form a/b where a and b are integers and B is not 0. Here, both 75 and 100 are integers, thus 75% is a rational number.

Irrational numbers are the opposite of rational numbers thus, 75% is not irrational.

All rational numbers and irrational numbers are REAL numbers, hence, 75% is a real number.

Natural numbers are whole digits starting from 1 e.g ( 1, 2, 3,......). Hence 75% is not a natural number

Whole numbers are natural numbers including 0. (0, 1, 2,.....). Hence, 75% is not a whole number

Integer numbers are comprises of both positive and negative whole numbers. (..., - 1, - 2, 0, 1, 2,...). Hence, 75% is not an integer.

Which of these is an exponential parent function? A. f(x) = 2^x – 3 B. f(x) = 2^x + 2 C. f(x) = 2^x D. f(x) = 2^x + 1/3

anygoal [31]

An exponential parent function is the option C. f(x)= $2^{x}$ , from the given options.

What do you mean by exponential parent function?

The formula for their parent function is y = $b^{x}$ , where b is any non zero constant. Below is a graph of the parent function, y = $e^{x}$ , which demonstrates that it will never equal 0. And at y = 1 when x = 0, y crosses the y-axis.

According to options in the given question,

We have the option below in the given question:

A. f(x) = 2^x – 3

B. f(x) = 2^x + 2

C. f(x) = 2^x

D. f(x) = 2^x + 1/3

We know from the above definition that the option C. is the right answer to the given question.

Therefore, the exponential parent function is f(x)= $2^{x}$ .

The graph shows the value of a certain model of car compared with it's age. which statement is true?

s2008m [1.1K]

The only true statement is A:

"The data show a negative linear relationship."

<h3></h3><h3>Which statement is true?</h3>

On the graph, we can see how the car's vale decreases almost linearly with the age of the car.

Where the response variable would be the one on the y-axis, which is the car's value.

For that linear behavior, we know that there is a correlation coefficient different than zero. So options B, C, and D are false.

Finally, we already saw the linear behavior (decreasing, so the slope is negative). Then we conclude that the only true statement is A.
