The probability that no more than 13 of the tickets have popcorn coupons is 0.1114.

It is a binomial distribution "DISCRETE probability distribution that encapsulates the likelihood that a value will take one of two independent values when a particular set of conditions is met. The assumptions for the binomial distribution are that each trial has a single possible outcome, each trial has an equal chance of success, and each trial is independent of the others or mutually exclusive ".

Let X the random variable of interest, on this case we now that:

X ∼ Binom( n = 18, p = 0.97)

The probability mass function for the Binomial distribution is given as:

P( X ) = ( ₙCₓ )(p)ˣ( 1 - p )ⁿ⁻ˣ

Where (ₙCₓ) means combinatory and it's given by this formula:

ₙCₓ = n! / ( n - x )! x!

And we want to find this probability:

P( X = 13 )

And using the probability mass function we got:

P( X = 13 ) = ₁₈C₁₃ ( 0.597 )¹³ ( 1 - 0.597 )¹⁸⁻¹³

P( X = 13 ) = 8568 × 0.00122367561 × 0.01062980336

P( X = 13 ) = 0.11144766975

The equation of the line, in point-slope form, that passes through (1, -2) and has a slope of 4 is expressed as: y + 2 = 4(x - 1).

The equation of a line in point-slope form is often expressed in the form of y - b = m(x - a), where a point is given as (a, b), and the slope of the line is represented as m.

Given the following:

A point on the line (a, b) = (1, -2)

The slope of the line (m) = 4

To write the equation of the line in point-slope form, substitute m = 4, a = 1, and b = -2 into y - b = m(x - a):

y - (-2) = 4(x - 1)

y + 2 = 4(x - 1) [equation of the line in point-slope form]

Answer:

108

Step-by-step explanation:

Like addition equations, the terms in multiplication equations can be arranged in any way and still return the same result. For example, 2 × 3 = 6, but 3 × 2 also equals 6. The same goes for 108 × 137, which can be written as 137 × 108.

To further confirm this, you can simply divide 14796 by 137, which results in 108.

Answer:

108

Step-by-step explanation:

any 2 numbers multiplied with eachother the answer is always the same. for eg:- 1×2=2 2×1=2

so, if 108 × 137 = 14796

then 137 × 108 = 14796

The actual length of the bus is 45 feet.

Given that, a scale drawing of a school bus has a scale of 1/2 inch to 5 feet.

Scale factor is a number by which the size of any geometrical figure or shape can be changed with respect to its original size.

Here, [tex]4\frac{1}{2} = \frac{9}{2}[/tex]

Let the actual length of the bus be x.

Now, the proportion is

1/2 : 5 :: 9/2 : x

⇒ x/2 = 45/2

⇒ x = 45 feet

Therefore, the actual length of the bus is 45 feet.

Answer:

150 square inches

Step-by-step explanation:

In a parallelogram opposite sides are parallel and equal.

   Perimeter = sum of all sides

    2x + 11 + x + 2x + 11 + x = 64

    2x + x + 2x +x + 11 + 11  = 64

Combine like terms,

                        6x + 22    = 64

                                   6x = 64 - 22

                                   6x = 42

                                     x = 42÷ 6

                                        [tex]\sf \boxed{\bf x = 7}[/tex]

base = 2x + 11

        = 2*7 + 11

        = 14 + 11

        = 25 in

height = 6 in

       Area of parallelogram = base * height

                                              = 25 * 6

The correct unit price of a pair of gloves is 1.23

What makes up a dozen?

The dozen of pairs of the gloves, contains 12 pairs each, which means that the total number of pairs in 7 dozens, is 12 multiplied by 7  as computed below:

number of pairs in 7 dozens=7*12

number of pairs in 7 dozens=84

In other words, instead of dividing the total cost of 103.32 by 7 to determine the unit price, we need to divide the total cost by 84 pairs found in 12 dozens instead

unit price=total cost/84

unit price=103.32/84

unit price=1.23

Note, that the unit price is for a pair since each pair is seen as a unit in this case as only one glove is useless

Suppose there is a number and the number has to be expressed as a fraction of 100. Then that number is called percentage.

The dimensions of his model of the train station would be

3 inches by 6 inches by 4 inches.

Scale factor is a dimensionless constant value that is used to compare the size of two objects. It is denoted by [K]. Mathematically -

K = O[1]/O[2]

Given is Lewis who is building a train layout and wants to build a model of the train station in his city. He wants it to be exactly to scale to match his engine. The engine measures 8 inches long and is the model of a train that is 80 feet long. The station in his city is 30 feet by 60 feet by 40 feet.

Now, it is given here that Lewis assumed a dilation model in which 80 feet is 8 inches long. Then -

80 feet = 8 inches

So one feet will be -

1 ft = 8/80 = 1/10 inches

Now, the dimensions of station in Lewis native city is 30 feet by 60 feet by 40 feet.

Now, dilating the dimensions with a scale factor of 1/10 inches, we get -

30 feet = 30 x 1 feet = 30 x 1/10 = 3 inches

60 feet = 60 x 1 feet = 60 x 1/10 = 6 inches

40 feet = 40 x 1 feet = 40 x 1/10 = 4 inches

Therefore, the dimensions of his model of the train station would be

3 inches by 6 inches by 4 inches.
