Answer 2

Answer:

the answer is [tex]27[/tex]

Step-by-step explanation:

First, you need to substitute a, b, and c for their sums

So your new problem should look like this... [tex]2+\left(3-\left(-2\right)\right)^2[/tex]

Then you can begin solving this problem using PEMDAS

So first you're going to start w/ the parenthesis... [tex]3-\left(-2\right)[/tex] which equals 5

Next, you're going to calculate the exponents, so it should look like this... [tex]5^{2}[/tex] which equals [tex]25[/tex]

So now your problem should look like this... [tex]5+25[/tex] which equals [tex]27[/tex]

So your answer is [tex]27[/tex]

hope this helps!

then devided by

15

The plumber worked for 12 hours.

What is an equation?

An equation can be defined as a statement that supports the equality of two expressions, which are connected by the equals sign “=”

Given that, a plumber charges a base fee of $60, and then each hour of work costs $15, yesterday, Joe hired the plumber to fix his sink, at a total cost of 240.

The equation for total cost t for working x hours will be,

60 + 15x = t

According to given situation,

60 + 15x = 240

15x = 180

x = 12

Hence, the plumber worked for 12 hours.

If I have three consecutive integers and three consecutive even integers how would they be represented differently? Explain. ***Three consecutive integers can be represented as x, x+1, and x+2

Answers

9514 1404 393

Answer:

  even integers differ by 2, consecutive integers differ by 1

Step-by-step explanation:

Often problems involving consecutive integers use a variable (x) to represent the least of them. In that situation, ...

   consecutive integers are x, x+1, x+2

   consecutive even (or odd) integers are x, x+2, x+4.

__

I often find it convenient to use the variable to represent the middle of the three integers. In that case, the representations are ...

  consecutive integers: x-1, x, x+1

  consecutive even (or odd) integers: x-2, x, x+2.

_____

In somewhat rare cases, you need to ensure that the integers are even, not odd, so the representation can be ...

  consecutive even integers: 2n, 2n+2, 2n+4 . . . . where n is any integer

Step-by-step explanation:

Evaluate from the ' inside out ' , that is

Evaluate g(2) then use this value to evaluate f(x) then use this value to evaluate h(x)

g(2) = 4(2)² - 9 = 4(4) - 9 = 16 - 9 = 7, then

f(7) = 7 + 7 = 14 , then

a) what is the null and alternative hypothesis

b) determine the test statistic

Answer:

a)

the null and alternative hypothesis will be;

Null hypothesis            H₀ : Ц = 18 ug/g

Alternative hypothesis  H₁ : Ц < 18 ug/g

b) the Test Statistic = -1.47

Step-by-step explanation:

Given data;

x = 22.5 , 9 , 18.5 , 22 , 16 , 18.5 , 15 , 3 , 8, 6

number of observation n = 10

level of significance ∝ = 0.01

a)

the null and alternative hypothesis will be;

Null hypothesis             H₀ : Ц = 18 ug/g

Alternative hypothesis  H₁ : Ц < 18 ug/g

b)

Test statistics;

using the formula;

t = (x" - Ц) / (s/√n)

x" is the sample mean

s is the standard deviation

Ц is the population mean ( 18 )

n is the number of observation ( 10 )

for first we get our mean x"

mean x" = ∑x / n

mean x" = (22.5  + 9  + 18.5  + 22  + 16  + 18.5  + 15  + 3  + 8 + 6) / 10

mean x" = 138.5 /10

mean x" = 14.85

Next we find the standard deviation s    

standard deviation s = √[ (∑(x-x")²) / (n - 1)]

x                     (x - x")                    (x - x")²

22.5                7.65                       58.5225

9                      -5.85                      34.2225

18.5                  3.65                       13.3225

22                    7.15                         51.1225

16                     1.15                          1.3225

18.5                  3.65                        13.3225

15                    0.15                         0.0225

3                      -11.85                       140.4225

8                     -6.85                        46.9225

6                     -8.85                        78.3225

total                                                437.525

so we substitute to get our standard deviation

standard deviation s = √[ (   437.525 / (10 - 1)]

= √[ 437.525 / 9]

= √48.6138

standard deviation s = 6.9723

Finally our we substitute our values into the Test statistics formula

t = (x" - Ц) / (s/√n)

t =  (14.85 - 18) / (6.9723/√10)

t = -3.25 /  2.2048

t =  -1.47

Therefore the Test Statistic = -1.47

Answer: The undefined word is used to define an angle is a point

Select C

The Undefined term that is used to define an angle is a point.

What is mean by Angle?

An angle is a combination of two rays (half-lines) with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.

Given that;

To find undefined term is used to define an angle.

Since, An angle is defined as the union of two rays with a common endpoint.

The common end point is known as the vertex of the angle while the rays are known as the sides of the angle.

And, A ray is a part of a line with one end point and proceeds on in one direction.

Thus, The Undefined term that is used to define an angle is a point.

Rhombus WXYZ with vertices W(1,5), X(6, 3),
Y(1, 1), and Z(-4, 3) in the x-axis.

Answers

9514 1404 393

Answer:

  W'(1,-5), X'(6,-3), Y'(1,-1), Z'(-4,-3)

Step-by-step explanation:

Reflection over the x-axis changes the sign of the y-coordinate. The x-coordinate remains unchanged.

The reflected points are ...

  W'(1,-5), X'(6,-3), Y'(1,-1), Z'(-4,-3)

Transformation involves changing the position of a shape

The coordinate of the rhombus after transformation is: W'(1,-5), X'(6,-3), Y'(1,-1), Z'(-4,-3)

The coordinates of the rhombus are given as:

W(1,5), X(6, 3), Y(1, 1), and Z(-4, 3)

The rule of reflection across the x-axis is:

[tex](x,y) \to (x,-y)[/tex]

When the above rule is applied to the rhombus, the image of the rhombus becomes

W'(1,-5), X'(6,-3), Y'(1,-1), Z'(-4,-3)

Hence, the coordinate of the rhombus after transformation is: W'(1,-5), X'(6,-3), Y'(1,-1), Z'(-4,-3)
