Answer:

$\large\boxed{e.\ \{a,\ b,\ c,\ d,\ 0,\ 2\}}$

Step-by-step explanation:

$\text{The union (denoted by}\ \cup\ \text{) of a collection of sets is the set of all elements of the sets. }\\\\A=\{0,\ 1,\ 2,\ 3\}\\\\B=\{a,\ b,\ c,\ d\}\\\\C=\{0,\ a,\ 2,\ b\}\\\\B\ \cup\ C=\{a,\ b,\ c,\ d,\ 0,\ 2\}$

Answer:

Option C is correct.

Step-by-step explanation:

An exponential function is of the form: $y =a(b)^x$ ....[1] where a is the initial value, x is any real number and b is the growth factor

Also, the b value (growth factor) has been replaced either by (1 + r) or by (1 - r).

Then, the growth "rate" (r) is determined as b = 1 + r.

and the decay "rate" (r) is determined as b = 1 - r

If b> 1, then it is exponential growth function.

if 0<b< 1. then it is exponential decay function.

Also, b = 1+ 4

Given the equation: $y = 50(1.15)^x$

On comparing given equation with [1] we get;

a = 50 and b = 1.15

Since, b = 1.15 > 1

Therefore, the given equation represents the exponential growth.

(A)

Yes, this $y = 50(1.15)^x$ equation represents the exponential growth.

(B)

Initial value (a) = 50

(C)

Here growth factor, b = 1.15

and

1+ r = 1.15.

⇒ $r = 0.15\%$

The GPA for the following on the scale of 4 GPA are; 88.69% -3.3, 87.15% - 3.3, 75.35% - 2.0 , 67.78% - 1.3, 63.14% - 1.0, 51.44% - 0.0

The Term GPA is a combined GPA or grade point average of all grades you have earned in a semester or term.

The Cumulative GPA is the overall GPA or grade point average of all cumulative GPA's that are earned in all semesters and all the courses in an academic term.

The GPA is total of averaged per semester; while the cumulative GPA is the total of all grades for all semesters That is; the difference between GPA and cumulative GPA.

The GPA for the following on the scale of 4 GPA are;

88.69% -3.3

87.15% - 3.3

75.35% - 2.0

67.78% - 1.3

63.14% - 1.0

51.44% - 0.0

1. All of the following are true except B. A. A random variable represents a numerical value assigned to an outcome of a probabi

kolezko [41]

Answer:

The true statements are :

A. A random variable is a numerical description of the outcome of a statistical experiment.

B. In most applications, discrete random variables represent counted data.

C. In most applications, continuous random variables represent measured data.

Step-by-step explanation:

It is true statement that,

A. A random variable is a numerical description of the outcome of a statistical experiment.

B. In most applications, discrete random variables represent counted data.

C. In most applications, continuous random variables represent measured data.

The false statement is -

D. The expected value of a discrete random variable is equal to the standard deviation of the random variable.

Reason -

The mean value, or expected value, of a discrete random variable X is given by the following equation:

μ = E(x) = ∑ x p(x)

And

The variance of a discrete random variable is given by the following formula:

σ²=∑ (x−μ)² P(x)

And

The square root of the variance, or, in other words, the square root of σ², is the standard deviation of a discrete random variable :

σ = √σ²
