In The Figure, C || D. What Are The Measures Of Angle 1 And Angle 2?

Answers

Answer 1

Answer:

Angle 1 = 105

Angle 2 = 75

Step-by-step explanation:

Angle 2 and angle 75 are corresponding angles.

Corresponding angles are equal.

So,

Angle 2 = 75

Angle 1 and angle 2 are linear pair angles.

Angle 1 + Angle 2 = 180

Angle 1 + 75 = 180

Angle 1 = 180 - 75

Angle 1 = 105

what is the next number in the series 7, 11, 2, 18, -7

Answers

The next number in the series is 25.

What is number?

Number is a fundamental concept in mathematics, used to represent a quantity. It can be represented in many forms, such as an integer, a fraction, a decimal, and a ratio. Numbers are used to measure and quantify almost every physical phenomenon in the world. They form the basis of scientific principles, such as Newton's law of gravitation, and are used in everyday life for activities such as counting and calculating. Number is also an important concept in other disciplines, such as philosophy, psychology, and sociology.

This series follows a pattern of adding the previous two numbers together. Therefore, the next number in the series is the sum of 25 and -7, which is 32. This pattern can be continued indefinitely, with the next number in the series being 39 (32 + 7) and so on.

#3 Preimage point B is
located at (5,-4).
B' is located at (20, -16).
Write the algebraic rule for
the transformation.

Answers

The algebraic rule for the transformation is B' = (Bx + 15, By - 12)

Given data ,

To determine the algebraic rule for the transformation from point B to point B', we need to find the equations that relate the coordinates of the preimage point B to the image point B'.

Let's denote the translation amounts in the x-direction and y-direction as (dx, dy). The coordinates of B' can be obtained by adding these translation amounts to the coordinates of B:

B' = (Bx + dx, By + dy)

Given that B is located at (5, -4) and B' is located at (20, -16), we can calculate the translation amounts:

dx = 20 - 5 = 15

dy = -16 - (-4) = -12

Hence , the algebraic rule for the transformation is B' = (Bx + 15, By - 12)

If somebody sells TVs and the formula they use is A = 800 + 200t and A = her total income and t = the amount they sell, how much money will they receive if they sell 9 TVs?

Answers

Answer:

$2600

Step-by-step explanation:

It is given that the variables:

A = total income

t = amount of TV they sell.

It is also given that they sold 9 TVs. Plug in 9 for t in the given equation:

A = 800 + 200t

A = 800 + 200(9)

A = 800 + 1800

A = 2600

$2600 is the total amount they will receive if they sell 9 TVs.

The national mean annual salary for a school administrator is $90,000 a year (The Cincinnati Enquirer, April 7, 2012). A school official took a sample of 25 school administrators in the state of Ohio to learn about salaries in that state and to see if they differed from the national average.

Required:
a. Formulate hypotheses that can be used to determine whether the population mean annual administrator salary in Ohio differs from the national mean of $90,000.
b. The sample data for 25 Ohio administrators is contained below. What is the p-value for your hypothesis test in part A?
c. At alpha = 0.05, can your null hypothesis be rejected? What is your conclusion?
d. Repeat the preceding hypothesis test using the critical value approach?

Answers

Answer:

Explained below.

Step-by-step explanation:

From the information provided:

\(n=25\\\bar x=85272\\s=11039.23\)

(a)

A hypothesis test is to performed to determine whether the population mean annual administrator salary in Ohio differs from the national mean of $90,000.

The hypothesis is:

H₀: The population mean annual administrator salary in Ohio is same as the national mean of $90,000, i.e. μ = 90000.

Hₐ: The population mean annual administrator salary in Ohio is different from the national mean of $90,000, i.e. μ ≠ 90000.

(b)

As the population standard deviation is not provided, a t-test will be used.

The test statistic value is:

\(t=\frac{\bar x-\mu}{s/\sqrt{n}}=\frac{85272-90000}{11039.23/\sqrt{25}}=-2.14\)

Compute the p-value of the test as follows:

\(p-value=2\times P(t_{n-1}<t)\\\\=2\times P(t_{24}<-2.14)\\\\=2\times P(t_{24}>2.14)\\\\=2\times 0.022\\\\=0.044\)

*Use a t-table.

Thus, the p-value of the test is 0.044.

(c)

The significance level of the test is, α = 0.05.

Decision rule:

Reject the null hypothesis if the p-value is less than the significance level.

p-value = 0.044 < α = 0.05.

The null hypothesis will be rejected at 5% level of significance.

Conclusion:

There is enough evidence to support the claim that the population mean annual administrator salary in Ohio differ from the national mean of $90,000.

(d)

The critical value of t is:

\(t_{\alpha/2, (n-1)}=t_{0.05/2, 24}=\pm 2.064\)

The rejection region  can be defined as follows:

\(t<-2.064\ \text{and}\ t>2.064\)

The test statistic value is, t = -2.14.

The test statistic value lies in the rejection region.

Thus, the null hypothesis will be rejected concluding that the population mean annual administrator salary in Ohio differ from the national mean of $90,000.

Equivalent expressions of z+(z+6)

Answers

Answer:

2z+6 or 2(z+3) are the equivalent expressions

Step-by-step explanation:

z+(z+6)

opening the brackets

z+z+6

=2z+6

or if we take 2 as common the answer is

=2(z+3)

i hope this will help you :)

Answer:

Given that the expression is z+(z+6)

The equivalent expression to the give expression

From the given expression z+ (z+6)

z+ (z+6)

=z+z+6

Adding the like terms

=2z+6

Taking the common term 2 outside of the above expression

=2(z+3)

Therefore z+ (z+6)  =2(z+3)

Therefore the other given optional expressions are not equivalent to the given expression.

The option 2(z+3) is correct and it is the equivalent expression.

Hence the given expression z+ (z+6)  is equivalent to the expression 2(z+3)
