Find the slope of the line that contains the following points: (17, -12) and (17, 8)
schepotkina [342]

Answer:

<em>m</em> = undef

General Formulas and Concepts:

<u>Pre-Algebra</u>

Order of Operations: BPEMDAS

  1. Brackets
  2. Parenthesis
  3. Exponents
  4. Multiplication
  5. Division
  6. Addition
  7. Subtraction
  • Left to Right<u> </u>

<u>Algebra I</u>

  • Coordinates (x, y)
  • Slope Formula: \displaystyle m=\frac{y_2-y_1}{x_2-x_1}

Step-by-step explanation:

<u>Step 1: Define</u>

Point (17, -12)

Point (17, 8)

<u>Step 2: Find slope </u><em><u>m</u></em>

Simply plug in the 2 coordinates into the slope formula to find slope<em> m</em>

  1. Substitute in points [Slope Formula]:                                                            \displaystyle m=\frac{-12-8}{17-17}
  2. [Fraction - Denominator] Subtract:                                                                 \displaystyle m=\frac{-12-8}{0}

We cannot divide anything by 0.

∴ Our slope <em>m</em> is undefined and it would be a vertical line if graphed.

Can you guys help me with this angle problem for Geometry tysm
steposvetlana [31]

Answer:

You need to solve for x

Step-by-step explanation:

3x + 5 + 10x - 7 = 180

13x + 5 - 7 = 180

13x - 7 = 175

13x = 182

x = 14

Plug in x

3(14) + 5 for QRT and 10(14) - 7 for TRS

QRT = 47 and TRS = 133

What's the answer ? I'm almost positive you do multiplication first then add but not I'm not sure . 1*2+3*4+5*6= 44
Airida [17]
PEMDAS
multiply first

1*2=2
3*4=12
5*6=30

now we have
2+12+30=44
add
2+12=14
14+30=44
44=44

Suppose you were given a 95% confidence interval for the difference in two population means. What could you conclude about the p
Savatey [412]

Answer:

(a) The population means are not same.

(b) The population means are same.

Step-by-step explanation:

The hypothesis to test whether there is a significant difference between two population means is:

<em>H₀</em>: There is no difference between the two population means, i.e.               <em>μ</em>₁ - <em>μ</em>₂ = 0.

<em>Hₐ</em>: There is no difference between the two population means, i.e.              <em>μ</em>₁ - <em>μ</em>₂ ≠ 0.

The decision rule based on confidence interval for the difference between two population means is:

If the confidence interval consists the null value of the difference, i.e. 0 then the null hypothesis will be accepted or else it will be rejected.

(a)

It is provided that the confidence interval for the difference between two population means does not contains 0.

Since the null value of the difference is not contained in the interval, it can be concluded that the null hypothesis will be rejected.

Thus, the population means are not same.

(b)

It is provided that the confidence interval for the difference between two population means does contains 0.

Since the null value of the difference is contained in the interval, it can be concluded that the null hypothesis will not be rejected.

Thus, the population means are same.

What is the alternating sum of digits
Morgarella [4.7K]

Answer:Take the alternating sum of the digits in the number, read from left to right. If that is divisible by 11, so is the original number. So, for instance, 2728 has alternating sum of digits 2 – 7 + 2 – 8 = -11. Since -11 is divisible by 11, so is 2728.

Hope this helped
