Please helpp i need this doneee :((
egoroff_w [7]

Answer:

w = \frac{5}{8}, v = \frac{21}{2}

Step-by-step explanation:

With given information, we have \frac{TR}{TQ} = \frac{TS}{TP}, so \frac{5}{13} = \frac{3w}{3w+3}, which gives us w=\frac{5}{8}. Meanwhile, we have \frac{TR}{TQ}=\frac{RS}{QP}, so \frac{5}{13}=\frac{10}{2v+5}, which gives us v = \frac{21}{2}.

Find the distance between the points (5,-6), (-3,12)
grigory [225]

Answer:

\displaystyle d = 2\sqrt{97}

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)

<u>Algebra II</u>

  • Distance Formula: \displaystyle d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Step-by-step explanation:

<u>Step 1: Define</u>

Point (5, -6)

Point (-3, 12)

<u>Step 2: Find distance </u><em><u>d</u></em>

Simply plug in the 2 coordinates into the distance formula to find distance<em> d</em>

  1. Substitute in points [Distance Formula]:                                                       \displaystyle d = \sqrt{(-3-5)^2+(12+6)^2}
  2. [√Radical] (Parenthesis) Subtract/Add:                                                         \displaystyle d = \sqrt{(-8)^2+(18)^2}
  3. [√Radical] Evaluate Exponents:                                                                    \displaystyle d = \sqrt{64+324}
  4. [√Radical] Add:                                                                                               \displaystyle d = \sqrt{388}
  5. [√Radical] Simplify:                                                                                     \displaystyle d = 2\sqrt{97}

You are interested in purchasing a new car. One of the many points you wish to consider is the resale value of the car after 5 y
gulaghasi [49]

Answer:

The 95​% confidence interval for the true mean resale value of a​ 5-year-old car of this​ model

(11,688.68 , 12,511.32)

Step-by-step explanation:

<u><em>Step(i)</em></u>:-

Given sample size 'n' = 17

mean of the sample x⁻ = 12,100

Standard deviation of the sample (S) = 800

The 95​% confidence interval for the true mean resale value of a​ 5-year-old car of this​ model

(x^{-} - t_{0.05} \frac{S}{\sqrt{n} } , x^{-} + t_{0.05} \frac{S}{\sqrt{n} } )

<u><em>Step(ii):-</em></u>

<u><em>Degrees of freedom ν =n-1 = 17-1 =16</em></u>

<u><em></em></u>t_{(16 , 0.05)} = 2.1199<u><em></em></u>

The 95​% confidence interval for the true mean resale value of a​ 5-year-old car of this​ model

(x^{-} - t_{0.05} \frac{S}{\sqrt{n} } , x^{-} + t_{0.05} \frac{S}{\sqrt{n} } )

(12,100 - 2.1199\frac{800}{\sqrt{17} } , 12,100 + 2.1199 \frac{800}{\sqrt{17} } )

(12,100 - 411.32 , 12,100 + 411.32)

(11,688.68 , 12,511.32)
