82. If AB has endpoint A (2,13) and midpoint (10, -1) then
give the coordinate of B.

Answers

Answer 1

Answer:

3

Step-by-step explanation:

Answer 2

The required coordinates of point B are (18, -15) where AB has endpoint A (2,13) and midpoint (10, -1).

What is the midpoint?

The midpoint formula states that the coordinates of the midpoint of a line segment with endpoints (x₁, y₁) and (x₂, y₂) are given by the formula (x₁ + x₂)/2, (y₁ + y₂)/2.

As per the question, we are given that AB has endpoint A (2,13) and midpoint (10, -1)

We can use these coordinates to find the coordinates of point B, which is the midpoint of line segment AB.

Let the coordinates of B would be (x, y)

Substituting the coordinates of points A into the midpoint formula gives us :

10 = (x+2)/2 ; -1 = (y+13)/2

20 = x +2 ; -2 = y + 13

x =  18 ; y = -15

Therefore, the required coordinates of point B are (18, -15).

The heights of dogs, in inches, in a city are normally distributed with a population standard deviation of 7 inches and an unknown population mean. If a random sample of 20 dogs is taken and results in a sample mean of 21 inches, find a 95% confidence interval for the population mean. z0.10z0.10 z0.05z0.05 z0.025z0.025 z0.01z0.01 z0.005z0.005 1.282 1.645 1.960 2.326 2.576 You may use a calculator or the common z values above. Round the final answer to two decimal places.

Answers

Answer:

The 95% confidence interval  is  [tex] 17.932  <  \mu <  20  + 22.068[/tex]

Step-by-step explanation:

From the question we are told that

  The population standard deviation is  [tex]\sigma =7 \ inches[/tex]

  The sample size is  n  =  20

  The sample mean is  [tex]\= x = 20[/tex]

From the question we are told the confidence level is  95% , hence the level of significance is    

      [tex]\alpha = (100 - 95 ) \%[/tex]

=>   [tex]\alpha = 0.05[/tex]

Generally from the normal distribution table the critical value  of  [tex]\frac{\alpha }{2}[/tex] is  

   [tex]Z_{\frac{\alpha }{2} } =  1.96[/tex]

Generally the margin of error is mathematically represented as  

      [tex]E = Z_{\frac{\alpha }{2} } *  \frac{\sigma }{\sqrt{n} }[/tex]

=>    [tex]E = 1.96 *  \frac{7 }{\sqrt{20} }[/tex]

=>    [tex]E = 2.068[/tex]        

Generally 95% confidence interval is mathematically represented as  

      [tex]\= x -E <  \mu <  \=x  +E[/tex]

=>     [tex] 20  - 2.068  <  \mu <  20  + 2.068[/tex]

=>     [tex] 17.932  <  \mu <  20  + 22.068[/tex]

Suppose the sum of two integers is negative. Must both integers be negative? Explain.

Answers

Answer:

Not necessarily. There are many ways to write a basic equation with a negative answer. For example, -3-4 = -7. Here 4 is a positive number but because you subtract 4 to 3 or take away 4 from 3 being a negative number and so you get a negative answer. Another example is 6+(-9). There are a couple of ways you can resolve this. My method is to subtract 9 from 6 which gives you 3 and simply add a negative sign.

Let me know if you'd  like more examples. Hope this helps!! Sorry if it is confusing I can explain you in a more simpler way if you'd like.

Step-by-step explanation:

The sum of two integers is negative, here both integers are negative.

What is inequality?

Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.

What are Arithmetic operations?

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operation is called the arithmetic operator.

Given that the sum of two integers is negative.

And both integers are negative

Let a < 0, b < 0

Using a model  a + b < 0

Substitute the values a = -1, b = -2, and c = -3 in the inequality of model

⇒ (-1) + (-2)  < 0

⇒ -1 - 2 < 0

⇒ -3 < 0

So, the sum of two integers is negative.

Hence, the sum of two integers is negative, here both integers are negative.

Express in standard form

A number in standard form can be expressed as:

[tex]a * 10^b[/tex]

Where

[tex]1 \leq a \leq 10[/tex]

i.e.

a is between 1 and 10 (inclusive) and preferable, a should be in 2 decimal places

We have that:

[tex]3.091403[/tex] is between 1 and 10.

So, in standard form it is:

[tex]3.091403 * 10^0[/tex]

Approximate to 2 decimal places

[tex]3.10* 10^0[/tex]

Hence, the standard form of [tex]3.091403[/tex] is [tex]3.10* 10^0[/tex]

The graph of function g is a parabola with the vertex located at (5,9). The parabola also passes through the point (3, 1). Which of the following is an
equation in vertex form for this function?

Answers

I just did this the answer is C. g(x) = –2(x – 5)2 + 9

The required function is [tex]g(x)=-2(x-5)^2+9[/tex].

Important information:

Vertex of parabola is at (5,9).Parabola passes through the point (3,1).

We need to find the equation in vertex form for the function g.

Parabola:

The vertex form of a parabola is:

[tex]g(x)=a(x-h)^2+k[/tex]         ...(i)

Where, [tex]a[/tex] is a constant and [tex](h,k)[/tex] is the vertex.

Substitute [tex]h=5,k=9[/tex] in (i).

[tex]g(x)=a(x-5)^2+9[/tex]          ...(ii)

Parabola passes through the point (3,1). So, substitute [tex]x=3,g(x)=1[/tex] in (ii).

[tex]1=a(3-5)^2+9[/tex]

[tex]1-9=a(-2)^2[/tex]

[tex]-8=4a[/tex]

[tex]-2=a[/tex]

Substitute [tex]a=-2[/tex] in (ii).

[tex]g(x)=-2(x-5)^2+9[/tex]

Thus, the required function is [tex]g(x)=-2(x-5)^2+9[/tex].

A hybrid SUV gets 32miles per gallon on the highway driving at a constant 55 miles per hour.At this rate, how many gallons per hour does the hybrid SUV use?

Answers

Answer:

a

Step-by-step explanation:

The hybrid SUV uses 32/55 gallons per hour which is the correct answer would be an option (A).

What are Arithmetic operations?

Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions.

The operator that perform the arithmetic operations are called arithmetic operators.

Operators which let do basic mathematical calculation

+ Addition operation : Adds values on either side of the operator.

For example 4 + 2 = 6

- Subtraction operation : Subtracts right hand operand from left hand operand.

for example 4 -2 = 2

* Multiplication operation : Multiplies values on either side of the operator

For example 4*2 = 8

Given that a hybrid SUV gets 32miles per gallon on the highway driving at a constant 55 miles per hour

To determine miles per gallon of gas,

We take the 32miles the hybrid SUV travels and divide it by the highway driving at a constant 55 miles per hour

⇒ 32/55

Hence, the hybrid SUV uses 32/55 gallons per hour.
