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

Answer:

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.

Answer:

A = 314 cm²

Step-by-step explanation:

the area (A) of a circle is calculated as

A = πr² ( r is the radius )

  = 3.14 × 10²

 = 3.14 × 100

 = 314 cm²

The expression that represents the volume of a cone with the same base and height as the cylinder is 1/3 * 20

The volume of the cylinder is given as:

V = 20

The volume of the cone is 1/3 of the volume of the cylinder.

So, we have:

v = 1/3 * V

Substitute 20 for V

v = 1/3 * 20

Hence, the expression that represents the volume of a cone with the same base and height as the cylinder is 1/3 * 20

The tree diagram that represents the events is an illustration of probability and combination

To draw the tree diagram, we make use of the following representations:

See attachment for the tree diagram.

From the tree diagram, the sample space is as follows:

S = {HR, HY, HB, TR, TY, TB}

This is represented as: TY

From the sample space above, we have:

TY = 1

Hence, the number of outcomes that represents "Toss a tail, spin yellow" is 1

We have:

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.

Answer:

D: 2x² +x -3

Step-by-step explanation:

If the width and length of the rectangle are 3 cm and 7 cm. Then the perimeter of the rectangle is 10 cm.

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 center.

Let L be the length of the rectangle and W be the width of the rectangle.

Then we have

4W + 3L = 33 ...1

 2W + L = 13 ...2

Then by the equations 1 and 2, we have

W = 3 and L = 7

Then the perimeter of the rectangle will be

Perimeter = W + L

Perimeter = 3 + 7

Perimeter = 10 cm

Answer:

1/12

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
