Answer:

\displaystyle r = \frac{d}{t}

General Formulas and Concepts:

<u>Algebra I</u>

Equality Properties

  • Multiplication Property of Equality
  • Division Property of Equality
  • Addition Property of Equality
  • Subtraction Property of Equality

Terms/Coefficients

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify.</em>

<em />\displaystyle d = rt<em />

<em />

<u>Step 2: Solve for </u><em><u>r</u></em>

  1. [Division Property of Equality] Divide <em>t</em> on both sides:                                  \displaystyle \frac{d}{t} = r
  2. Rewrite:                                                                                                             \displaystyle r = \frac{d}{t}

<h3>Answer:  x = -1</h3>

Explanation:

The given quadratic is in the form y = ax^2 + bx + c

We have a = 1, b = 2, c = 2

This then leads to

h = -b/(2a)

h = -2/(2*1)

h = -1

This is the x coordinate of the vertex (h,k)

The axis of symmetry is the vertical line passing through the vertex. So it must share the x value in question.

Meaning the axis of symmetry is x = -1. Every point on this vertical line has an x coordinate of -1. This line of symmetry splits the parabola into two equal mirrored halves.

I recommend using a graphing tool like Desmos to visually confirm the answer.

If (x – 4) + 6 = 2 - (4 - 2x), then x =<br> A. -4<br> B. -2<br> C. 2<br> D. 4
blondinia [14]

Answer:

x=4

Step-by-step explanation:

Remove the parentheses and turn the 4-2x and make it into 4+2x candle the equal term -4 and should be left with x+6=2+2x then move the variable to the left and change the sign so it would be x-2x=2-6 and collect like terms so it would be -x=2-6 and then calculate that and get -x= -4

(sorry its alot)

A barrel of 20 apples has 2 rotten apples and 18 good apples. 7 apples are selected at random from the barrel. What is the expec
KengaRu [80]

Answer:

Expected value = 7 x 0.9 = 6.3

Step-by-step explanation:

Probability of getting a good apple is 18/20 = 0.9

Probability of getting a bad apple is 2/20 = 0.1

This follows a binomial distribution because either you get a good apple or a bad apple.

The expected value of a binomial distribution is given as n*p where n is number of trials and p is the probability of success.

In this case our number of trials is 7 and the probability of success is 0.9, since the trials are for getting good apples.

Hence

n = 7

p = 0.9

Expected value = 7 x 0.9 = 6.3
