The odds in favor of winning a prize in the contest of the juice company which gives prizes to anyone finding specially marked caps is 3.2.

In probability, the term odds against is the ratio of probability of non occurring a favorable event to the probability of occurring a favorable event. It can be given as,

[tex]\text{odd against}=\dfrac{P(\overline A)}{P(A)}[/tex]

Here, [tex]P(\overline A)[/tex] is the probability of not occurring a favorable event, and P(A) is the probability of occurring a favorable event.

A juice company gives the prizes to anyone finding specially marked caps on its juice bottles. The 4 bottles have winning cap in 20 bottles. Thus, the probability of winning is,

[tex]P(A)=\dfrac{4}{20}\\P(A)=\dfrac{1}{5}[/tex]

The probability of not winning is,

[tex]P(\overline A)=1-\dfrac{1}{5}\\P=\dfrac{4}{5}[/tex]

Thus, the odd against the winning is,

[tex]\text{odd against}=\dfrac{\dfrac{4}{5}}{\dfrac{1}{4}}\\\text{odd against}=\dfrac{16}{5}\\\text{odd against}=3.2[/tex]

Thus, the odds in favor of winning a prize in the contest of the juice company which gives prizes to anyone finding specially marked caps is 3.2.

Answer:

50

Step-by-step explanation:

I got you this the answer

The required result of the division can be written as:

1258 ÷ 24 = 52 R 14, where R 14 means "52 with a remainder of 14".

In mathematics, divides left-hand operands into right-hand operands in the division operation.

For example 4/2 = 2

When you divide 1258 by 24, the result is a whole number with a remainder.

To find the result of this division, you can use a long division.

24 ) 1258 (52

    -   120

--------------------

       58

    -  48

--------------------

        14

--------------------

So, 1258 divided by 24 is equal to 52 with a remainder of 14.

Answer:

After 7 days there are the same number of both calendars left in the store

Step-by-step explanation:

Let x be defined by the number of days,

41 total, 3 Ocean calendars sell each day

48 total, 4 Space calendars sell each day

expression: 41 - 3x = 48 - 4x

- we set them equal to find when x amount days are the same for both calendars

- we subtract due to selling each calendars

solving:

41 - 3x = 48 - 4x                      

add 4x to both sides, trying to get like terms on the same side

41 - 3x + 4x = 48 - 4x + 4x

41 + x = 48

now subtracts 41 from both sides to get x alone

41 - 41 + x = 48 - 41

x = 7

Step-by-step explanation:

The value of √-4 and not -2 because

-2 * -2 = + 4.

Also there is no real number whose square is a negative.

Hi Student!

This question can seem quite complex but it has a simple explanation.  Just imagine, what is the purpose of a square root?  It shows what can by multiplied against itself and produce the number that is in the square root.  That is why when we take the square root of 4 we get 2 and -2 because they both produce the number 4 when we square them.  Whenever we square a number, no matter if it's positive or negative, the answer will always be positive.  This is because in order to get a negative number only one can be negative to overcome the positive otherwise it's just a double negative.

Therefore, there is a solution to the question of what is the square root of -4.  What we do is practically take out the negative because the square root of -1 is equal to i.  So we take the following steps

Separate the square root

Simplify the expression

Looking at what we have done, we see that although the explanation behind it might seem complex the actual solving portion isn't too hard when explained.  Therefore, the solution to the square root of -4 would be 2i.

Answer:

[tex](x + 4)^{2} + (y + 1)^{2} = 29[/tex].

Step-by-step explanation:

The equation of a circle of radius [tex]r[/tex] and center [tex](a,\, b)[/tex] is:

[tex](x - a)^{2} + (y - b)^{2} = r^{2}[/tex].

In this question, it is given that the center is [tex](-4,\, -1)[/tex], such that [tex]a = (-4)[/tex] while [tex]b = (-1)[/tex].

The radius of this circle could be found as the distance between the center of this circle, [tex](-4,\, -1)[/tex], and any point on the circle- such as [tex](1,\, -3)[/tex]. Using the distance formula, the radius of this circle would be:

[tex]\begin{aligned}r &= \sqrt{((-4) - 1)^{2} + ((-1) - (-3))^{2}} \\ &= \sqrt{29}\end{aligned}[/tex].

Therefore, the equation of this circle would be:

[tex](x - (-4))^{2} + (y - (-1))^{2} = (\sqrt{29})^{2}[/tex].

Simplify to obtain:

[tex](x + 4)^{2} + (y + 1)^{2} = 29[/tex].

The expressions which are equivalent to the trigonometric function cos(theta) are cos(2pi+theta) and cos(-theta)

Equivalent expressions are the expression whose result is equal to the original expression, but the way of representation is different.

The given trigonometric expressions is,

[tex]f(\theta)=\cos\theta[/tex]

The cosine function is the periodic function. The function repeats itself after the 2π. Thus,

[tex]f(\theta)=\cos\theta\\f(\theta)=\cos(2\pi+\theta)[/tex]

The cosine function is an even function. Thus,

[tex]f(\theta)=\cos\theta\\f(\theta)=\cos(-\theta)[/tex]

Cuboid = 200 ft^2

Parallelogram = 27.8 cm^2

Cylinder = 138 yd^2

We can be able to obtain the surface area of various figures by the use of formulas.

For the rectangle, the surface area is = 7.1 yd * 5.1 yd = 36.2 yd^2

For the cuboid, the surface area = 2[(8 ft * 14 ft) + (4 ft * 8ft) + (14ft * 4 ft)] = 200 ft^2

For the parallelogram, the surface area = 5.4 cm * 5.14 cm = 27.8 cm^2

Answer:

Looking at the given points we know that it is going to be a triangle because it only have 3 points.  Therefore the figure is a triangle and the area formula would be [tex]A=\frac{1}{2}*b*h[/tex].

You can look at the attached graph and what we see is that our height of the triangle is from [tex]y=-3[/tex] to [tex]y=4[/tex] which means that our height is 7 units high.  We can also see that our base starts at [tex]x=-4[/tex] and ends at [tex]x=4[/tex] making us have a base of 8 units.

We then plug in the values and solve

[tex]A = \frac{1}{2}*7\ units * 8\ units[/tex]

[tex]A = \frac{1}{2}*56\ units^2[/tex]

[tex]A = 28\ units^2[/tex]

Therefore, the area of our triangle is [tex]28\ units^2[/tex]

Step-by-step explanation:

x² - 12x + 32 = 0

the goal is the vertex form : a form like

(x - h)² + k = r²

with (h, k) being the vertex or center and r the radius.

doing all the multiplications we get

x² - 2hx + h² + k - r² = 0

and we compare this with our original equation. we see

x² = x²

-12x = -2hx

-12 = -2h

6 = h

32 = h² + k - r²

32 = 36 + k - r²

-4 = k - r²

possible solution : k = 0 and then r = 2

but also e.h. k = 12, r = 4

so, without the information about e.h. the radius we cannot identify one solution.

so, "A" vertex form (one of many possible ones) is

(x - 6)² = 4

x = number of matching questions

y = number of essay questions

x >= 3

x <= 12

y >= 4

y <= 15

x + y <= 20

the delimiter lines are therefore

x = 3

x = 12

y = 4

y = 15

y = 20 - x

when you graph these lines, the corners (intersection points) of the inner shaded area are

(3, 4)

(12, 4)

(3, 15)

(12, 8)

(5, 15)

the other intersection points

(12, 15)

(3, 17)

(16, 4)

are outside the inner shaded area.

b.

10x + 25y = score

and this we want to maximize.

we have to try the 5 corners from a. and see, which one gives the maximum score.

(3, 4) gives

10×3 + 25×4 = 30 + 100 = 130

(12, 4) gives

10×12 + 25×4 = 120 + 100 = 240

(3, 15) gives

10×3 + 25×15 = 30 + 375 = 405

(12, 8) gives

10×12 + 25×8 = 120 + 200 = 320

(5, 15) gives

10×5 + 25×15 = 50 + 375 = 425

The measure of the diagonal of the rectangular garden will be 7.2 feet. Then the correct option is a.

It is a polygon with four sides. The total interior angle is 360 degrees. A rectangle's opposite sides are parallel and equal, and each angle is 90 degrees. Its diagonals are all the same length and intersect in the centre.

Landon has a rectangular garden with an area of 24.7 square feet. If the length of the garden is 5.7 feet.

Then the width of the garden will be

Area = Length x Width

24.7 = 5.7 x  W

 W = 4.33

Then the measure of the diagonal of the rectangular garden will be

D² = L² + W²

D² = 5.7² + 4.33²

D² = 32.49+ 18.74

D² = 51.23

D = 7.2

D ≅ 7.2 feet

Thus, the correct option is a.
