In a Bag there are four white marbles and four blue marbles. if two marbles are drawn out at the same time what is the probability that both marbles it will be white

Answer:

$3520

Step-by-step explanation:

Conversion

To convert feet to yards, we divide the measurement of feet by 3 hence for dimenaion given as 48 ft, it will be 48÷3=16 yards

The area will be given by the product of length and width and since both measurements are given

A=lw

A=16*20=320 yd²

Cost will be 320*11=$3520

Therefore, the department will have to pay $3520 for the work to be completed

Answer:

13.9% marginal

Step-by-step explanation:

The percentage of tickets sold to Seniors can be found as:

[tex]p(s)=\frac{S}{N}\cdot 100[/tex]

where

S is the number of all tickets sold to seniors

N is the total number of tickets sold

By looking at the table, we see that:

S = 32 + 14 + 54 = 100 is the number of tickets sold to seniors

N = 35 + 87 + 62 + 56 + 177 + 205 + 32 + 14 + 54 = 722 is the total number of tickets sold

Therefore, the percentage is:

[tex]p(s)=\frac{100}{722}\cdot 100 =13.9\%[/tex]

The three different types of frequencies are defined as:

- Joint: the frequency of a single category calculated with respect to the total number --> this is not the case

- Marginal: the frequency of an entire row/column over the total --> this is the case

- Conditional: the frequency of a single category over a subset of the total --> this is not the case

So, the correct answer is

13.9% marginal

The cyclist rode a total of 172 miles in 9 hours, covering 92 miles at 23 mph for 4 hours and 80 miles at 16 mph for 5 hours.

To find out how far the cyclist rode in 9 hours, we need to calculate the distance covered at each speed and then add those distances together. The cyclist rode at a constant speed of 23 mph for 4 hours and then at a speed of 16 mph for 5 hours.

First, we calculate the distance at 23 mph:

Distance = Speed × Time
Distance at 23 mph = 23 mph × 4 hours = 92 miles

Next, we calculate the distance at 16 mph:

Distance at 16 mph = 16 mph × 5 hours = 80 miles

Now, we add the distances together to get the total distance:

Total Distance = Distance at 23 mph + Distance at 16 mph
Total Distance = 92 miles + 80 miles = 172 miles

Therefore, the cyclist rode a total of 172 miles in 9 hours.

Answer:

16 oz, 12 oz, 4 oz

Step-by-step explanation:

Since 1 pound is equal to 16 ounces, and you can only use each weight once or not at all, you can determine how much is needed by simply adding.

2 pounds is equal to 32 ounces.

To achieve 32 ounces, you can use a 16 ounce weight, which will then bring the scale to need 16 ounces.

After this you can youse a 12 ounce weight, which brings it down to 4 ounces.

The last weight needed is the 4 ounce weight which will then level out the balance scale.

the answer is C. they are both positive.

Step-by-step explanation:

This is because over the y axis is the first quadrant which is always positive.

Final answer:

Upon reflection over the y-axis, the x-values of the vertices become negative, and the y-values remain positive; hence, option A is correct.

Explanation:

The question asks what is true about the vertices of a triangle located in the first quadrant of the coordinate plane when it is reflected over the y-axis. A reflection over the y-axis in the Cartesian coordinate system would mean that for any point (x, y) on the triangle, the x-coordinate would change its algebraic sign while the y-coordinate would remain the same. This is due to the properties of reflection over an axis where coordinates perpendicular to the axis of reflection change signs, and those parallel remain unchanged.

The correct answer here would be A. The x-values are negative because they are reflected across the y-axis, changing their signs from positive to negative. However, the y-values would remain positive since the triangle is still located in the quadrant above the x-axis, where y-values are positive.

Step-by-step explanation:

Answer: The correct options are options 1 and 4.

The quadrilaterals cannot be placed such that each occupies one quarter of the circle because the vertices of parallelogram 1 do not form right angles.

The quadrilaterals cannot be placed such that each occupies one quarter of the circle because the vertices of parallelogram 4 do not form right angles.

Step-by-step explanation: When you have the dimensions of a quadrilateral given along with the diagonal (which is also the hypotenuse) you basically have the quadrilateral divided into two triangles. You can determine if the triangles are going to be right angled or not simply by using the Pythagoras theorem as a test.

Note also that if the angles are right angled, then the quadrilaterals can all be conveniently placed, one in each quarter of the circle without overlapping. This is possible because each quarter of a circle measures 90 degrees.

To test if the angles formed are right angled we shall take the following steps;

Pythagoras theorem states that; AC² = AB² + BC²

Where AC is the longest side (hypotenuse), and AB and BC are the other two sides.

(Quad 1) ------> 20² = 12² + 15²

400 = 144 + 225

400 ≠ 369

Both sides pf the equation are not equal, hence the vertices of parallelogram 1 do not form a right angle.

(Quad 2)------> 34² = 16² + 30²

1156 = 256 + 900

1156 = 1156

Both sides of the equation are equal, hence the vertices of parallelogram 2 forms a right  angle

(Quad 3)------> 29² = 20² + 21²

841 = 400 + 441

841 = 841

Both sides of the equation are equal, hence the vertices of parallelogram 3 forms a right angle

(Quad 4)------> 26² = 18² + 20²

676 = 324 + 400

676 ≠ 724

Both sides sides of the equation are not equal, hence the vertices of parallelogram 4 do not form a right angle.

From the results shown above, if the four parallelograms are placed in each of the four corners of the circle, they would definitely overlap because two of them do not form right angles at their vertices.

Answer:

B & E

Step-by-step explanation:

The quadrilaterals cannot be placed such that each occupies one-quarter of the circle because the vertices of parallelogram 1 do not form right angles.

The quadrilaterals cannot be placed such that each occupies one-quarter of the circle because the vertices of parallelogram 4 do not form right angles.

The length of side "s" of the square is 3 units, as it is equal to one of the legs of the 45-45-90 right triangle formed by the diagonal of the square.

To find the length of side "s" of the square shown below, we can use trigonometry, specifically the properties of right triangles and the fact that the diagonal divides the square into two congruent 45-45-90 right triangles.

Given information:

The diagonal of the square measures 6 units.

One of the angles at the top of the square is 45 degrees.

Step 1: Recognize the properties of the 45-45-90 triangle:

Since the diagonal divides the square into two congruent right triangles, and one angle is 45 degrees, we have a 45-45-90 triangle. In such a triangle, the two legs (the sides opposite the 45-degree angles) are congruent, and the hypotenuse (the side opposite the 90-degree angle) is √2 times the length of a leg.

Step 2: Use trigonometric ratios:

Let "x" be the length of one leg of the 45-45-90 triangle, which is also equal to side "s" of the square.

From the properties of the 45-45-90 triangle:

x (leg) = s (side of the square)

Hypotenuse = √2 * leg

Given that the diagonal of the square is 6 units, we can relate the diagonal to the legs:

Diagonal = 2 * leg

6 = 2 * x

Now, solve for x (the length of one leg of the triangle and side "s" of the square):

x = 6 / 2 = 3 units

So, the length of side "s" of the square is 3 units.

Therefore, from the given options the correct one is B.

According to the information given in the exercise, you know that:

[tex]Angle\ formed \ by\ two\ tangents = m\angle EYL\\\\Difference\ of\ Intercepted\ Arcs=m LVE-mLHE[/tex]

Since there are 360 degrees in a circle, you can determine that:

[tex]mLVE=360\°-mLHE\\\\mLVE=360\°-84\°\\\\mLVE=276\°[/tex]

Therefore, knowing these values, you can substitute them into the formula given above and the evaluate, in order to find the measure of the angle EYL. This is:

[tex]m\angle EYL=\frac{1}{2}(276\°-84\°) \\\\m\angle EYL=96\°[/tex]

Answer:

x + 97 = 180

The equivalent expression is: (C) [tex]$\frac{1}{3^9 \cdot 6^{18}}$[/tex].

To simplify the given expression, we can apply the rules of exponents.

First, we raise 3 to the power of 3 and 6 to the power of 6, individually:

3^3 = 27 and 6^6 = 46656.

Next, we multiply these two values together:

27 * 46656 = 1259712.

Now, we raise the result to the power of -3:

1259712^(-3).

To simplify this expression, we can rewrite it as the reciprocal of the base raised to the positive exponent:

(1 / 1259712^3).

This can be further simplified by raising the base to the power of 3:

(1 / (1259712 * 1259712 * 1259712)).

Finally, we can simplify the expression by multiplying the denominators:

1 / (1954890816015872).
