Answer:

14 red marbles.

Step-by-step explanation:

If I am reading this correctly, since the probablitly of choosing a blue marble is 7/9, then 7/9 of the bag must be blue marbles. That amounts to 7/9*63=49 and the bag containing 49 blue marbles. Therefor, 63-49=14 is the number of red marbles in the mag.

The ratio of nonwinners in group A to nonwinners in group B after the selections are made is 156 : 319.

Ratio expresses the relationship between two or more numbers. It shows the frequency of the number of times that one value is contained within other value(s).

Nonwinners in group A = (1 - 3/5) x 390 = 156

Winners in group B = (390 - 156) = 234

nonwinners in group B = 553 - 234 = 319

The ratio = 156 : 319

Step-by-step explanation:

this simply means that the coordinates are multiplied by the scale factor.

(a, b) -> (a×k, b×k)

that's it.

so, the first answer is correct.

well, since we know the point L is on the circle, that means that the segment RL is really the length of the radius of that circle, hmmm let's see what that might be

[tex]~~~~~~~~~~~~\textit{distance between 2 points} \\\\ R(\stackrel{x_1}{2}~,~\stackrel{y_1}{4})\qquad L(\stackrel{x_2}{0}~,~\stackrel{y_2}{8})\qquad \qquad d = \sqrt{( x_2- x_1)^2 + ( y_2- y_1)^2} \\\\\\ RL=\sqrt{[0 - 2]^2 + [8 - 4]^2}\implies RL=\sqrt{(-2)^2+4^2}\implies \boxed{RL=\sqrt{20}}[/tex]

since RL is its radius, anything larger than that is outside the circle, and anything smaller than that is inside it.  Let's check for the distance RQ.

[tex]~~~~~~~~~~~~\textit{distance between 2 points} \\\\ R(\stackrel{x_1}{2}~,~\stackrel{y_1}{4})\qquad Q(\stackrel{x_2}{6}~,~\stackrel{y_2}{7})\qquad \qquad d = \sqrt{( x_2- x_1)^2 + ( y_2- y_1)^2} \\\\\\ RQ=\sqrt{[6 - 2]^2 + [7 - 4]^2}\implies RQ=\sqrt{4^2+3^2}\implies RQ=\sqrt{25}[/tex]

needless to say RQ is larger than RL.

The probability that each person gets off on a different floor is; 3/32

We are told that there are 4 people on the elevator. We are also told that there are four stops on four different floors. Thus;

Total number of ways to get off on the floors = 4 * 4 * 4 * 4 = 256 ways

Now, the number of ways that each person can get off on a different floor is 4! = 24. Thus, the probability that each person gets off on a different floor is;

P(each person gets off on a different floor) = 24/256 = 3/32

Answer:

Step-by-step explanation:

The initial probability of drawing a blue marble would be 3/9 as there are initially 3 blue marbles and in the bag there are a total of 9 marbles however, to get the second blue marble, the probability would be 2/8 since there's one less blue marble in the bag, making it 2 and one less marble in the bag, in general, leaving 8 marbles in the bag. To find the combined probability of getting both blue marbles, multiply the probabilities so:

3/9 x 2/8 = 1/3 x 1/4 = 1/12

Using the formula, we can find that the surface area is 208 in².

Step-by-step explanation:

To find the surface area (SA) for a rectangular prism, substitute its dimensions into the formula and solve.

Dimensions mean the side lengths of the shape, the height, width and length. We know the dimensions from the question.

Height: h = 6 in

Width: w = 8 in

Length: l = 4 in

We will need the formula to find the surface area for rectangular prisms. Note that different shapes have a different formula for finding surface area.

[tex]SA= 2(lw + lh + hw)[/tex]

Substitute the dimensions h = 6in, w = 8in and l = 4in into the formula.

[tex]SA= 2((4\ in)(8\ in) + (4\ in)(6\ in) + (6\ in)(8\ in))[/tex]

Remember order of operations (BEDMAS) when solving. Multiply within the brackets first.

[tex]SA= 2(32\ in^{2} + 24\ in^{2} + 48\ in^{2})[/tex]       Add within the brackets.

[tex]SA= 2(104\ in^{2})[/tex]                                 Multiply.

[tex]SA= 208\ in^{2}[/tex]                                      Final answer

Tip: The final answer for area will always have squared units.

∴ The surface area (SA) of the rectangular prism with a height of 6 inches, width of 8 inches, and length of 4 inches is 208 squared inches.

Please give brainliest!

Hope this helps :)

the answer to the expression 8:4(5+2) is approximately 0.2857.

To solve the expression 8:4(5+2), we follow the order of operations, also known as PEMDAS (Parentheses, Exponents, Multiplication and Division from left to right, Addition and Subtraction from left to right).

First, we simplify the expression inside the parentheses: 5 + 2 = 7.

Next, we perform the multiplication: 4 * 7 = 28.

Finally, we perform the division: 8 ÷ 28 = 0.2857 (rounded to four decimal places).

So, the answer to the expression 8:4(5+2) is approximately 0.2857. Remember that it's crucial to follow the order of operations to arrive at the correct result in mathematical expressions.

The least common denominator (LCD) is: 30.

Rewriting as equivalent fractions with the LCD:

1/2 5/6 2/3 3/5

15/30 25/30 20/30 18/30

Sorting this table by the numerators of the equivalent fractions in order from least to greatest:

Answer:

∠ 1 = 36° , ∠ 2 = 144°

Step-by-step explanation:

∠ 1 and ∠ 2 are adjacent angles on a straight line and sum to 180° , that is

x + 12 + 6x = 180

7x + 12 = 180 ( subtract 12 from both sides )

7x = 168 ( divide both sides by 7 )

x = 24

Then

∠ 1 = x + 12 = 24 + 12 = 36°

∠ 2 = 6x = 6 × 24 = 144°
