The expression that represents the change Mrs. Smith got back is 50 - x dollars.

A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.

Given, A pet store is having a pet fish sale.

let, the cost of the Koi fish is 'x' dollars.

Therefore, With a $50 bill change(C) Mrs. Smith got back is represented by the expression,

C = (50 - x) dollars.

So, The change Mrs. Smith got back is 50 - x dollars.

Answer:

 point (-2,11)  does not lie on the given line

Step-by-step explanation:

To find : Which of the following points does not lie on the line ?

Solution :

To determine the point lie on line or not we have to put points in equation if it satisfy then it lie otherwise not.

a) Point (1,8)

Line  y=3x+5

Substitute x=1 and y=8

8=3(1)+5

8=8

(1,8) point lie on the line.

b) Point (4,12)

Line y=3x+5

Substitute x=4 and y=17,

17=3(4)+5

17=12+5

17=17

(4,17) point does not lie on the line.

c) point (-2,11)

Line y=3x+5

substitute x=-2 and y=11

11=3(-2)+5

11=-6+5

11 is not equal to -1

d) Point(0.5)

Line y=3x+5

Substitute x=0 and y=5

5=3(0)+5

5=5

Step-by-step explanation:

The equation that represents the condition that the events are nonexclusive is P(E1 ∪ E2) ≠ 1.

We have given that,

A. P(E1 ∩ E2) ≠ 0 B. P(E1 ∪ E2) ≠ 1 C. P(E1 ∩ E2) = 0 D. P(E1 ∪ E2) = 1

We have to determine which equation represents the condition that the events are nonexclusive.

Non-mutually exclusive events are events that can happen at the same time.

The equation that represents the condition that the events are nonexclusive is P(E1 ∪ E2) ≠ 1.

Step-by-step explanation:-2 + 2 = 0 + 2= 2 + 2 = 4

The function table is solved and the quadratic equation is f ( x ) = -3x²

A quadratic equation is a second-order polynomial equation in a single variable x , ax² + bx + c=0. with a ≠ 0. Because it is a second-order polynomial equation, the fundamental theorem of algebra guarantees that it has at least one solution. The solution may be real or complex.

The roots of the quadratic equations are

x = [ -b ± √ ( b² - 4ac ) ] / ( 2a )

where ( b² - 4ac ) is the discriminant

when ( b² - 4ac ) is positive, we get two real solutions

when discriminant is zero we get just one real solution (both answers are the same)

when discriminant is negative we get a pair of complex solutions

Given data ,

Let the quadratic equation be represented as A

Now , the value of A is

f ( x ) = -3x²

when x = -2

f ( -2 ) = -3 ( -2 )²

f ( -2 ) = -12

And , when x = 0

f ( 0 ) = 0

when x = 2

f ( 2 ) = -12

when x = 4

f ( 4 ) = -48

Hence , the function table is f ( x ) = { -12 , 0 , -12 , -48 }

Answer:

z = -2.13

Therefore, the standardized z score for the state of Colorado means the score is below the mean.

Step-by-step explanation:

The formula for z score is given as:

z = (x-μ)/σ,

where

x is the raw score = 9.7%

μ is the population mean = 13.26%

σ is the population standard deviation = 1.67%

z = z score or standardize score

Hence,

z = 9.7 - 13.26/1.67

z = -2.13174

Approximately z = -2.13

Therefore, the standardized z score for the state of Colorado means the score is below the mean
