A bag contains tickets numbered 1 through 5. Use the probability distribution to determine the probability of drawing an odd numbered ticket.
The probability of drawing an odd numbered ticket is __ %
Answers
Answer:
The probability of drawing an odd numbered ticket is 60%.
Step-by-step explanation:
Odd numbered tickets:
Probability of one is 1/5 plus half of 1/5.
\(P(X = 1) = \frac{1}{5} + \frac{1}{10} = \frac{3}{10}\)
Probability of 3 is half of 1/5.
\(P(X = 3) = \frac{1}{10}\)
Probability of 5 is 1/5. So
\(P(X = 5) = \frac{1}{5}\)
Probability of drawing an odd numbered ticket:
\(p = P(X = 1) + P(X = 3) + P(X = 5) = \frac{3}{10} + \frac{1}{10} + \frac{1}{5} = \frac{4}{10} + \frac{2}{10} = \frac{6}{10} = 0.6\)
0.6*100% = 60%
The probability of drawing an odd numbered ticket is 60%.

Answer:
1.32km (answer might differ slightly due to different values of speed of sound, in the range of 320 to 340 ms-1)
Step-by-step explanation:
Speed of lightning = 3 x 10^8 m/s (same as speed of light)
Speed of sound = 330 m/s (most common answer for speed of sound)
Let the time taken for lightning be T seconds
Time taken for thunder to reach her = (T + 4) seconds
Hence, an equation can be formed
Distance between lightning and her = Distance between thunder and her
Distance = Speed x Time
T(3x 10^8) = (T+4)(330)
((3 x 10^8) - 330)T = 4(330)
Solving, T = 4.40 x 10^-6
Hence,
Distance from storm = (4.40 x 10^-6)(3 x 10^8) metres
= 1320m

A cloth bag contains 6 cards numbered 1 through 6. Two cards are drawn without replacement. What is the probability that the sum of the numbers on the two drawn cards is 7
Answers
Answer: \(\dfrac15\)
Step-by-step explanation:
Given : A cloth bag contains 6 cards numbered 1 through 6. Two cards are drawn without replacement.
Favorable outcome: sum of the numbers on the two drawn cards is 7
Since 1+6 = 7 , 2+5=7, 4+3 = 7
So, sum of 7 can be obtained as (1, 6), (2, 5), (3, 4), (4, 3), (5, 2) and (6, 1)
Probability of getting (first 1, second 6) = \(\dfrac16\times\dfrac15=\dfrac{1}{30}\)
Probability of getting (first 2, second 5) = (\(\dfrac16\times\dfrac15=\dfrac{1}{30}\)
Probability of getting (first 3, second 4) =\(\dfrac16\times\dfrac15=\dfrac{1}{30}\)
Probability of getting (first 4, second 3) = \(\dfrac16\times\dfrac15=\dfrac{1}{30}\)
Probability of getting (first 5, second 2) = \(\dfrac16\times\dfrac15=\dfrac{1}{30}\)
Probability of getting (first 6, second 1) =\(\dfrac16\times\dfrac15=\dfrac{1}{30}\)
Required probability =\(6\times\dfrac{1}{30}=\dfrac15\)
Hence, the required probability = \(\dfrac15\)

The store had a discount of $2 off her total purchase. Nicole and her friend then divided the cost of the purchase evenly. Which expression can be used to determine how much Nicole and her friend each paid for the apples?
Answers
6 pounds * $1.50 per pound = $9
Then, we can subtract the discount:
$9 - $2 = $7
Since Nicole and her friend split the cost evenly, we can divide $7 by 2:
$7 / 2 = $3.50
Therefore, each of them paid $3.50 for the apples.
The expression that can be used to determine this is:
($6 * $1.50 - $2) / 2 = $3.50
where $6 is the total cost of 6 pounds of apples at $1.50 per pound and $2 is the discount
A homeowner is planning to paint an 8 foot by 22 foot wall and wants to determine the cost of the project. She tests a 14 inch by 18 inch section of the wall and finds that 1 ounce of paint is needed for good coverage. If she uses paint that costs $28 per gallon, what will be the cost of the paint needed to give the entire wall a good coverage of paint?
Answers
The cost of the paint needed to give the entire wall a good coverage of paint is $22
Firstly, we need to calculate the equivalent areas
Mathematically, we know that 1 ft is 12 inches
So to calculate the area of the wall in square inches, we have;
\(8\times22\times12\times\text{ 12 = 25,344 sq. inches}\)Now let us calculate the area of the test;
We have this as;
\(14\times\text{ 18 = 252 sq.inches}\)Now, we know that1 ounce is okay for the test, the number of ounces okay for the main wall would be;
\(\frac{25,344}{252}\text{ }\times\text{ 1 ounce =100.60 ounces}\)So, 100.60 ounces of paint would be enough to cover the wall
Finally, we proceed to get the cost of this as follows;
Mathematically, 1 ounce is 0.0078125 gallons
So, the number of ounces would be;
\(100.60\times0.0078125\text{ = 0.786 gallons}\)From the question, the cost per gallon is $28
So, the cost in 0.786 gallons would be;

if a is a set of real numbers which is bounded above and b is a set of real numbers which is bounded below then there is at most one real number in both a and b?
Answers
If a is a set of real numbers that is bounded above and b is a set of real numbers that is bounded below, there is at most one real number that can exist in both sets.
A real number is any number that can be expressed as a decimal or fraction and exists on the number line.
If a set of real numbers, represented by a, is bounded above, it means that there exists a real number, represented by M, such that all the numbers in the set are less than or equal to M. Similarly, if a set of real numbers, represented by b, is bounded below, it means that there exists a real number, represented by m, such that all the numbers in the set are greater than or equal to m.
Now, let's consider a real number, represented by x, that exists in both sets a and b. If x exists in a, it must be less than or equal to M and if x exists in b, it must be greater than or equal to m. Hence, x must satisfy both conditions: M >= x >= m.
From these conditions, it can be deduced that M and m must be equal to x. In other words, there can only be one real number that is simultaneously the greatest value in a and the smallest value in b.

B. What is each piece measurement if the angle is cut into 9 equal
lengths? Kerf width is 0.125.
Answers
Each piece Measurement of an angle of 120 degrees cut into nine equal lengths with a kerf width of 0.125 would be 14.4583 degrees.
When a particular angle is cut into nine equal parts, the measure of each piece needs to be calculated.
Therefore, it is essential to first calculate the total angle measure and then divide it by the number of parts into which it is being cut.
What is an Angle?
An angle is a geometrical shape that consists of two rays sharing a common endpoint. The common endpoint is known as the vertex, and the two rays are known as the arms of the angle. An angle can be measured in degrees, radians, or gradians. Degrees are the most commonly used unit of measuring angles.How to Calculate Each Piece Measurement of an Angle if Cut into 9 Equal Lengths
To determine each piece measurement of an angle if cut into nine equal lengths, we will need to carry out the following steps:
Step 1: Calculate the total angle measure Suppose the angle being cut into nine equal lengths is an obtuse angle measuring 120 degrees. In that case, the total angle measure will be 120 degrees.
Step 2: Divide the total angle measure by the number of parts into which it is being cut.120 degrees ÷ 9 = 13.3333 degrees
Step 3: Add the kerf width to the piece measurements.0.125 x 9 = 1.125 degrees13.3333 + 1.125 = 14.4583 degrees
Therefore, each piece measurement of an angle of 120 degrees cut into nine equal lengths with a kerf width of 0.125 would be 14.4583 degrees.

Point K is located at ( 1 , 2 ) on the following coordinate plane. A square that has a perimeter of 20 units will be drawn so that K is one vertex of the square. Which three ordered pairs could represent the location of another vertex of the square? Select the three correct answers.
Answers
Three ordered pairs that could represent the location of another vertex of the square are (7, 2), (-5, 2), (1, 8).
To find the possible locations of the other vertices of the square, we need to determine the distance from point K to any other vertex of the square. Since the perimeter of the square is 20 units, each side of the square has a length of 20/4 = 5 units.
One way to find the other vertices is to draw a circle with center at K and radius 5 units, and then look for points on the circle that have integer coordinates. Alternatively, we can use the distance formula to calculate the distance from K to another point (x, y), which must be 5 units, and then solve for y in terms of x.
Using the distance formula, we get:
\(\sqrt{(x-1)^{2} +(y-1)^{2} }\) = 5
Simplifying and squaring both sides, we get:
(x-1)^2 + (y-2)^2 = 25
Expanding the left side and simplifying, we get:
\(x^{2}\) - 2x + \(y^{2}\) - 4y + 20 = 0
Completing the square for x and y, we get:
\((x-1)^{2}\) + \((y-1)^{2}\) = \(6^{2}\)
This is the equation of a circle with center at (1, 2) and radius 6 units. Any point on this circle that has integer coordinates could be a vertex of the square, since it will be exactly 5 units away from K.
Using this method, we can find several possible locations of the other vertices of the square. Three of them are:
