The probability of drawing a silver ball out of a certain bag is

1 third. What is the probability of not drawing a silver ball?

Answer:

$76.80

Step-by-step explanation:

When a product has a certain markup, you need to multiply the markup by the price of the product, and then add that to the original price of the product. 20%=0.2, and 0.2*64=12.8. Adding this to the original price, you get 64+12.8=$76.80. Hope this helps!

Answer:

$76.8

Step-by-step explanation:

64 x .2 = 12.8

64 + 12.8 = 76.8

Final answer:

The correct simplified form is \(\frac{1}{r^7} + \frac{1}{s^{12}}\), with each term representing the reciprocal of the base raised to a positive exponent and kept as separate terms.

Explanation:

The simplified form of r-7 + s-12 is \(\frac{1}{r^7} + \frac{1}{s^{12}}\). The negative exponents indicate that each term is the reciprocal of the base raised to the positive exponent. So, r-7 becomes \(\frac{1}{r^7}\) and s-12 becomes \(\frac{1}{s^{12}}\). Since these are two separate terms, they are not combined together into a single fraction.

First, calculate the volume of water needed to fill the pond one-quarter of the way up, then multiply that by the cost per cubic foot to find the total cost, which is approximately $2297.29.

The subject of this question is Mathematics, more specifically, it involves the use of geometry and algebra. The question is asking about the cost of filling a cylindrical pond one-quarter of the way up with water, given the dimensions of the pond and the price of water per cubic foot.

To answer this question, we first need to determine the volume of water needed. Since the pond is cylindrical, we use the formula for the volume of a cylinder: V = πr²h, where r is the radius and h is the height. The diameter is given as 30 feet, so the radius is 15 feet (half the diameter), and we're filling to a depth of 1.25 feet (one-quarter of the 5-foot depth). This gives us a volume of approximately 706.86 cubic feet.

We then multiply this volume by the price of water. At $3.25 per cubic foot, that's a total cost of about $2297.29. So, you would need to spend approximately $2297.29 to fill the pond one-quarter of the way up with water.

Answer:

y=1

Step-by-step explanation:

Let's solve by opening the bracket first

-5-(15y-1)=2(7y-16)-y

Open the bracket

-5-15y+1=14y-32-y

Collect like terms

-5+1+32=14y-y+15y

-5+33=14y+14y

28=28y

Divide both sides by 28

y=1

Therefore the final answer is 1

Answer:

A = 400 cm^2

Step-by-step explanation:

The perimeter of a square is given by

P = 4s where s is the side length

80 = 4s

Divide each side by 4

80/4 = 4s/4

20 =s

We want to find the area of the square

A = s^2

A = 20^2

A = 400 cm^2

Answer:

I think its A

Step-by-step explanation:

Radius of a sphere with a volume of 26,244π inches³ is 27 inches.

Volume of a sphere, V = (4/3)πr³.

Given the volume of 26,244π inches³,

(4/3)πr³ = 26,244π

The radius of sphere (r) =

r³ = (26,244π)/(4/3)π

r³ = 26,244 × (3/4)

r³ = 19,683

r = ∛19,683

r = 27 inches

The radius of the sphere is 27 inches.

The formula for the volume (V) of a sphere with radius (r) is given by:

[tex]\[ V = \frac{4}{3} \pi r^3 \]Given that the volume (\( V \)) of the sphere is \( 26,244\pi \) cubic inches, we can set up the equation:\[ 26,244\pi = \frac{4}{3} \pi r^3 \]To solve for \( r \), we first divide both sides by \( \frac{4}{3} \pi \):\[ r^3 = \frac{26,244\pi \times \frac{3}{4}}{\pi} \]\[ r^3 = 19,683 \][/tex]

Taking the cube root of both sides:

[tex]\[ r = \sqrt[3]{19,683} \]\[ r \approx 27 \][/tex]

Therefore, the radius of the sphere is 27 inches.

Answer: B: 35ab^2c AND 7bc^2

Step-by-step explanation:

The monomials must be multiples of 7bc such as 21b^2c and 14bc^2, because the GCF of two monomials is the highest factor that divides both these monomials. GCF in this case is 7bc.

The Greatest Common Factor (GCF) of two monomials is the highest factor that divides both of these monomials. Given that the GCF is 7bc, these two monomials must have 7bc as a factor. Thus, Valerie possibly used any two monomials that are multiples of 7bc.

For example, one answer could be 21b^2c and 14bc^2. Each of these monomials has 7bc as a factor (3b, 2c, and 2b, 2c respectively). There are other possible combinations, as long as they're multiples of 7bc.

Answer:

-63/16

Step-by-step explanation:

csc x = 5/3

sin x = 3/5

So x is the angle in a 3-4-5 triangle, opposite of the 3.

cos y = 5/13

So y is the angle in a 5-12-13 triangle, opposite of the 12.

tan(x + y) = (tan x + tan y) / (1 − tan x tan y)

tan(x + y) = (3/4 + 12/5) / (1 − (3/4)(12/5))

tan(x + y) = (3/4 + 12/5) / (1 − 9/5)

tan(x + y) = (15 + 48) / (20 − 36)

tan(x + y) = -63/16

Answer:

c 32

Step-by-step explanation:

Given:

a) Area = 121 ft²

b) Area = 81 yd²

To find:

The side length of each square

Solution:

a) Area = 121 ft²

Area of the square = s²

⇒ s² = 121

Taking square root on both sides.

[tex]\Rightarrow \sqrt{s^2} = \sqrt{ 121}[/tex]

[tex]\Rightarrow \sqrt{s^2} = \sqrt{ 11^2}[/tex]

Square root and squares get canceled.

⇒ s = 11

The length of each side of the square is 11 ft.

b) Area = 81 yd²

Area of the square = s²

⇒ s² = 81

Taking square root on both sides.

[tex]\Rightarrow \sqrt{s^2} = \sqrt{ 81}[/tex]

[tex]\Rightarrow \sqrt{s^2} = \sqrt{ 9^2}[/tex]

Square root and squares get canceled.

⇒ s = 9

The length of each side of the square is 9 yd.

Answer:

0.7 or 70 percent

Step-by-step explanation:

Jay's probability of winning the next game, based on his past record, would be 70%. However, probability doesn't guarantee future outcomes as the future performance depends on various factors.

The question requires us to find out the probability of Jay winning the next video game he plays, given his past record. Jay has won 14 out of the last 20 games, which gives us a winning probability of 14/20 = 0.7 or 70%. Probability assumes the conditions remain the same, it doesn't guarantee that the next outcome will be a win.

However, notice that past performance doesn't necessarily indicate future results, especially in random situations such as a game. The future outcome depends on the conditions of the next game he plays and his performance in it. The past winning record of 70% can be taken as an indication of Jay's skills or chances under similar conditions, but not a certainty for future games.

Answer:

B) 1/5

Step-by-step explanation:

First you would have to find the total number of days.

52 + 13 = 65

The total number of days is 65.

Reread the question. The question is, "What is the approximate probability that she will see deer in her yard tomorrow?"

She has seen deer in her yard for 13 days, so the equation to figure this out would be:

13 divided by 65 = 0.2 or 1/5

I also took the Quiz and got it correct :)

(If you found this helpful and got it correct please thank, give 5 stars, and comment your feedback if you can so others know it's correct as well.)

The probability of seeing a deer in her yard tomorrow is 1/5, the correct option is B.

Probability is the likeliness of an event to happen, it has a range from 0 to 1.

Total number of days Maria saw deer is 13 days

Total number of days Maria didn't saw the deer is 52 days

The total number of days is 65

Probability of seeing a deer = Number of days deer was seen / Total          

                                                                                           number of days

Probability = 13/65

Probability = 1/5

Step-by-step explanation:

2. y + 3 = -2x^2 + 5

3. y = 2x^2 - 8x + 6

6. y = 5x (x+9) - 8

Out of the given functions, y + 3 = –2 x 2+ 5, y = 2 x 2 – 8 x + 6, y = 5 x(x + 9) – 8 and y – 2 x 2 = 3 x – 2 x 2 + 4 are quadratic functions. They fit the standard quadratic form a*x^2 + b*x + c = y.

A function can be classified as a quadratic function if it can be written in the standard form a*x^2 + b*x + c = y, where a, b, and c are constants and a is not equal to zero. Quadratic functions graph as a parabola.
