packs of collectible cards claim that 1 out of 3 packs contains a rare card. margie bought 7 packs and only received a rare card in 1 of the packs.

margie runs a simulation of 100 trials. in the simulation, she used a random number generator to select 7 digits from 1 to 3 with 1 representing a pack with a rare card and 2 and 3 representing a pack without a rare card. the frequency of the number of packs with rare cards in each trial of 7 samples in the simulation is represented by this table.

what is the best conclusion for margie to make based on the data?


the claim that 1 out of 3 packs contains a rare card is plausible because the simulation shows that only 1 pack with a rare card out of 7 is likely.

the claim that 1 out of 3 packs contains a rare card is plausible because the simulation shows that only 1 pack with a rare card out of 7 is unlikely.

The indicated side of the right triangle is [tex]44\sqrt{2} =\frac{88}{\sqrt{2} }[/tex].

A triangle is classified as a right triangle when it presents one of your angles equal to 90º.  The greatest side of a right triangle is called hypotenuse. And, the other two sides are called cathetus or legs.

The math tools applied for finding angles or sides in a right triangle are the trigonometric ratios or the Pythagorean Theorem.

The Pythagorean Theorem says:[tex]hypotenuse^2=(leg_1)^2+(leg_2)^2[/tex]. And the main trigonometric ratios are:

[tex]sin(\beta )= \frac{opposite\;leg}{hypotenuse} \\ \\ cos(\beta )= \frac{adjacent\;leg}{hypotenuse} \\ \\ tan(\beta )= \frac{opposite\;leg}{adjacent\;leg} \\ \\[/tex]

The question asks to find one of the legs (y). Then, you can find y applying the trigonometric ratio (sin 45°).

[tex]sin(45\°)=\frac{y}{88}[/tex]

Like sin45° is equal to [tex]\frac{\sqrt{2} }{2}[/tex], you have

[tex]\frac{\sqrt{2} }{2} =\frac{y}{88}\\ \\ 2y=88\sqrt{2} \\ \\ y=44\sqrt{2} \\ \\ Thus\\ \\ y=\frac{88}{\sqrt{2}}[/tex]

Answer:

2 miles

Step-by-step explanation:

Peter takes 7 minutes and 30 seconds per mile.

7 times 2 is 14 minutes.

30 seconds times 2 is 1 minute.

If you add these 2 values together you get 15 minutes.

So we need to times the miles by 2 to get 2 miles.

In this specific case, the initial term (a) is 5 and the common ratio (r) is -2

Henceforth, after determining what a and r are, we use the formula for the nth term. Which is:

[tex]a_n = a \times r^{n-1} [/tex]

Therefore, the 14th term is :

[tex]\implies 5 \times { (- 2)}^{14 - 1} \\\implies 5 \times {( - 2)}^{13} \\ =\boxed { -40,960} [/tex]

The total area of the given composite figure is; 84.8 ft²

We are given;

Area of triangle = 5.6 ft²

Thus, area of 2 triangles = 2 * 5.6 = 11.2 ft²

Area of rectangles = 2(3.6 * 2) + 2(2 * 4) + 3(4 * 3.6)

Area of rectangles = 14.4 + 16 + 43.2

Using a geometric sequence, it is found that the approximate value of the car at the end of the 10th year will be given by:

A. $6,974.

A geometric sequence is a sequence in which the result of the division of consecutive terms is always the same, called common ratio q.

The nth term of a geometric sequence is given by:

[tex]a_n = a_1q^{n-1}[/tex]

In which [tex]a_1[/tex] is the first term.

In this problem, the first term and the common ratio are given, respectively, by:

[tex]a_1 = 18000, q = \frac{16200}{18000} = 0.9[/tex]

Hence the equation is:

[tex]a_n = 18000(0.9)^{n-1}[/tex]

At the end of the 10th year, the value will be of:

[tex]a_{10} = 18000(0.9)^{10-1} = 6974[/tex]

The initial amount of the water is 15 gallons

These are functions that has a leading degree of 1. Given the equation that represents the amount of water remaining after x minutes;

y - 12 = -3(x- 1)

y -12 = -3x + 3

y = -3x +3 + 12

y = -3x + 15

In order to determine the initial amount of water, we will substitute x =0 into the function

y = -3(0) + 15

y = 15

Hence the initial amount of the water is 15 gallons

Step-by-step explanation:

Answer:

y = (x+8)(x+3)

Step-by-step explanation:

If you multiply

(x+8)(x+3),

you get x^2 + 3x + 8x + 24

This simplifies to x^2 + 11x + 24, same as the original question.

The graph of y=x² + 11x + 24 is equivalent to the y=(x+8)(x+3).

An algebraic expression known as a polynomial requires that all of its exponents be whole numbers. Any polynomial must have variable exponents that are non-negative integers. Constants and variables are components of a polynomial.

We have Graph whose equation is

y=x² + 11x + 24

Now, factories the above equation using splitting the middle term

y=x² + 11x + 24

y=x² + 8x + 3x + 24

y = x(x+8) + 3(x+8)

y= (x+3)(x+8)

Thus, the factors are (x + 3)(x+8).

By completing squares, we will see that the radius is 12 units and the center is (-8, 1).

The circle of center (x₁, y₁) and radius r is written as:

(x - x₁)² + (y - y₁)² = r²

Now we go to our equation:

x² + 16x + 64 + y² - 2y + 1 = 144

Now we need to complete squares:

(a + b)² = a² + 2ab + b²

Then we can rewrite:

(x² + 2*8*x + 8*8) + (y² - 2y + 1) = 12²

(x + 8)² + (y - 1)² = 12²

So the center is the point (-8, 1) and the radius is 12 units.

Answer:

second term: 10

A correct answer is option A which is x² + (y – 3)² = 36 is the equation of the circle that has a diameter of 12 units and a center that lies on the y-axis.

A circle is a two-dimensional geometry on the plane having a center point and the circular line is drawn equidistant from the center point.

The general form of the equation of a circle is given as:-

( x - h )² + ( y - k )² = r²

By comparing the given equation we can see the following results:-

x² + (y – 3)² = 36

( x - ( 0 ))² + ( y - 3 )² = 6²

We can see that the coordinate of the center are ( 0, 3 ) and the radius is 6 so the diameter is 12.

Therefore the correct answer is option A which is x² + (y – 3)² = 36 is the equation of the circle that has a diameter of 12 units and a center that lies on the y-axis.

The simple interest in which Casho invests money was 8%.

Simple interest is often a predetermined percentage of the principle amount borrowed or lent paid or received over a specific time period.

We know simple interest (SI) is given by SI = (p×r×t)/100, where

p = principle, r = rate in percentage, and t = time in years.

Given, p = 30, SI = (32.40 - 30) = $2.40 and t = 1.

Therefore, 2.40 = (30×r×1)/100.

240 = 30r.

r = 240/30.

r = 24/3.

r = 8.

So, The rate of simple interest is 8%.
