Answer:

p(4) = $10.69

p(14) = $20.79

p(14) - p(4) = $10.10

p( 14) - p(4)/14-4, and interpret this result

$1.01 This means that during this interval of 10 years, ticket prices increased, on average, $1.01 a year.

Step-by-step explanation:

The average ticket price for a baseball game, in p years after 1991, can be modeled by the following equation:

p(x) = 0.03x^{2} + 0.47x + 8.33

Find p(4).

p(4) = 0.03*4^{2} + 0.47*4 + 8.33 = 10.69

Find p(14).

p(4) = 0.03*14^{2} + 0.47*14 + 8.33 = 20.79

Find p( 14) - p(4).

20.79 - 10.69 = 10.10

Find p( 14) - p(4)/14-4, and interpret this result.

10.10/10 = 1.01.

This is the yearly average rate that the ticket price changed during this interval. This means that during this interval of 10 years, ticket prices increased, on average, $1.01 a year.

What is the probability that a point chosen at random in the given figure will be inside the larger square and outside the small
In-s [12.5K]

Answer:

P(inside larger square and outside smaller) = \frac{51}{100}

Step-by-step explanation:

Probability is the result of the division of the number of possible outcome by the number of an event.

In the question, for a point chosen, the point can be in the small square only or in the area or region between the small square and the big square as such,

Area of larger square = area of region between both squares + area of smaller square

Where the area of a square is S × S where S is the side of a square

Area of larger square = 10 × 10

                                    = 100 cm square

Area of smaller square = 7 × 7

                                      = 49 cm square

Area of the region between  both squares

                                      = 100 - 49

                                      = 51 cm square

The probability that a dot selected is inside the larger square and outside the smaller is

P(inside larger square and outside smaller) = Area of region between both square/ Area of larger square

P(inside larger square and outside smaller) = \frac{51}{100}

You roll a pair of fair dice until you roll “doubles” (i.e., both dice are the same). what is the expected number, e[n], of roll
bonufazy [111]

We need to define our outcomes and events.

 

Finding the probability<span> of each event occurring separately, and then multiplying the probabilities is the step to <span>finding  the probability</span> of two independent events that occur in sequence.

</span>

<span>
To solve this problem, we take note of this:</span>

 

The roll of the two dice are denoted by the pair

(I, j) ∈ S={ (1, 1),(1, 2),..., (6,6) }

Each pair is an outcome. There are 36 pairs and each has probability 1/36. The event “doubles” is { (1, 1),(2, 2)(6, 6) } has probability p= 6/36 = 1/6. If we define ”doubles” as a successful roll, the number of rolls N until we observe doubles is a geometric (p) random variable and has expected value E[N] = 1/p = 6.

Write the equation of the line that passes through (1, 3) and has a slope of 2 in point-slope form. (2 points) y − 1 = 2(x − 3)
NARA [144]

Answer:

  y − 3 = 2(x − 1)

Step-by-step explanation:

The point-slope form of the equation of a line with slope m through point (h, k) is ...

  y -k = m(x -h)

You have m=2, h=1, k=3, so the equation is ...

  y -3 = 2(x -1)

I suppose you just have to simplify this expression.

(2ˣ⁺² - 2ˣ⁺³) / (2ˣ⁺¹ - 2ˣ⁺²)

Divide through every term by the lowest power of 2, which would be <em>x</em> + 1 :

… = (2ˣ⁺²/2ˣ⁺¹ - 2ˣ⁺³/2ˣ⁺¹) / (2ˣ⁺¹/2ˣ⁺¹ - 2ˣ⁺²/2ˣ⁺¹)

Recall that <em>n</em>ª / <em>n</em>ᵇ = <em>n</em>ª⁻ᵇ, so that we have

… = (2⁽ˣ⁺²⁾ ⁻ ⁽ˣ⁺¹⁾ - 2⁽ˣ⁺³⁾ ⁻ ⁽ˣ⁺¹⁾) / (2⁽ˣ⁺¹⁾ ⁻ ⁽ˣ⁺¹⁾ - 2⁽ˣ⁺²⁾ ⁻ ⁽ˣ⁺¹⁾)

… = (2¹ - 2²) / (2⁰ - 2¹)

… = (2 - 4) / (1 - 2)

… = (-2) / (-1)

… = 2

Another way to get the same result: rewrite every term as a multiple of <em>y</em> = 2ˣ :

… = (2²×2ˣ - 2³×2ˣ) / (2×2ˣ - 2²×2ˣ)

… = (4×2ˣ - 8×2ˣ) / (2×2ˣ - 4×2ˣ)

… = (4<em>y</em> - 8<em>y</em>) / (2<em>y</em> - 4<em>y</em>)

… = (-4<em>y</em>) / (-2<em>y</em>)

… = 2
