Answer:

The probability of selecting a face card or a spade when randomly selecting one card from a standard deck of cards is 11/26 or approximately 0.423.

Step-by-step explanation:

Part A

No, selecting a face card and selecting a spade when randomly selecting one card from a standard deck of cards are not mutually exclusive events. This is because there are face cards that are also spades, so there is an overlap between the two events.

Part B

The probability of selecting a face card or a spade when randomly selecting one card from a standard deck of cards can be calculated as follows

P(face card or spade) = P(face card) + P(spade) - P(face card and spade)

Part C

The probability of selecting a face card or a spade when randomly selecting one card from a standard deck of cards can be calculated as follows

P(face card or spade) = P(face card) + P(spade) - P(face card and spade)

P(face card or spade) = 12/52 + 13/52 - 3/52

P(face card or spade) = 22/52

P(face card or spade) = 11/26

Hence, the probability of selecting a face card or a spade when randomly selecting one card from a standard deck of cards is 11/26 or approximately 0.423.

1 kilogram of soil will fit in the container, since 1 kilogram is less than 27/5 kilograms.

We can start by using ratios to solve this problem.

From the information given, we know that:

We want to know how much soil will fit in the entire container (which is equivalent to 3 times the amount that fills 1/3 of the container)

To find out how much soil fills the entire container, we can set up a ratio:

(3/5 kg of soil) : (1/3 of container) = (x kg of soil) : (1 container)

We can cross-multiply to solve for x:

(3/5 kg of soil) * (1 container) = (1/3 of container) * (x kg of soil)

Multiplying both sides by 3/1 gives:

(3/5) * 3 * (1 container) = (1/3) * x

Simplifying gives:

9/5 = 1/3 * x

Multiplying both sides by 3 gives:

27/5 = x

As per the given temperature, the new reading is  0°F

The formula for converting Fahrenheit to Celsius is (°F - 32) x 5/9 = °C. We can use this formula to determine the new temperature in Celsius and then convert it back to Fahrenheit.

First we have to convert the initial temperature to Celsius

(-20°F - 32) x 5/9 = -28.89°C

Now we have to add 20 degrees Fahrenheit to the initial temperature

-20°F + 20°F = 0°F

And then we have to convert the new temperature to Celsius

(0°F - 32) x 5/9 = -17.78°C

When we convert the new temperature from Celsius back to Fahrenheit

-17.78°C x 9/5 + 32 = 0°F

Therefore, the new reading on the thermometer will be 0 degrees Fahrenheit, which indicates that the temperature has risen by 20 units on the Fahrenheit scale.

[tex]x = 2cos(t)*cos^2(t) = 2x^2 - 2y^2[/tex]

A math equation is a mechanism for connecting statements and indicating equivalence with both the equals symbol (=). An equation is an algebraic claim that asserts the equivalency of two formulae in algebra. In the calculation 3x + 5 = 14, for example, the equivalence sign separates the numbers 3x + 5 and 14. To explain the relationship among the two words on each surface of a letter, a formula can really be employed. The software and the logo are usually interchangeable. For instance, 2x - 4 equals 2.

Set T = 300 in the equation and solve for t to discover the number of minutes it takes for the oven's temperature to reach 300°F:

T = 400 - It

300 = 400 - It / subtraction T = 300

It = 400 - 300

It = 100

t = 100 / I

T = 400 minus It I = (400 minus T) / t

When we substitute T = 0 and T = 1, we get:

I = (400 - 0) / 1\sI = 400

Now we can substitute I = 400 into the equation we found before for t:

t = 100 / I\st = 100 / 400\st = 0.25

As a result, it takes around 0.25 minutes for the oven to reach 300°F, or roughly 15 seconds. Rounded to the closest minute, the answer is 0 minutes.

Corresponding angles are pairs of angles that are formed when a straight line intersects two parallel lines.

They are located on opposite sides of the transversal (the line that intersects the parallel lines) and in corresponding positions. Corresponding angles have the same degree measurement as each other.

angle 1 = 82 degrees corresponding angles are equal

angle a = 58 degrees corresponding angles are equal

angle a and angle 2 are linear pair hence angle a and angle 2 are supplementary angles

Answer:

To find the perimeter and area of the square garden shed without graphing the coordinates, you can use the distance formula to calculate the length of one side of the square. The distance formula is d = √((x2 - x1)^2 + (y2 - y1)^2), where (x1, y1) and (x2, y2) are the coordinates of two points. Using this formula with the coordinates of two adjacent corners of the square, such as (-2,8) and (1,8), we find that the length of one side of the square is 3 units. Since all sides of a square are equal in length, the perimeter is 4 times the length of one side, or 12 units. The area of a square is equal to the length of one side squared, so the area of the square garden shed is 9 square units.

This problem is different from finding the perimeter and area of the base of a house because it involves a square shape rather than a more complex shape. However, you can use similar strategies to solve both problems by calculating distances between points and using geometric formulas to find perimeter and area. The specific formulas used may vary depending on the shape of the base of the house.

c = √[(x2 - x1)² + (y2 - y1)²]

c = √[(-7 - 3)² + (1 - (-4))²]

c = √[(-10)² + 5²]

c = √(100 + 25)

c = √125

c ≈ 11.2

Based on the given question, Molly needs a loan of $1,000

A loan occurs when one or more people, businesses, or other entities lend money to other people, businesses, or other entities.

The recipient incurs a debt and is often responsible for both the principal amount borrowed as well as interest payments until the debt is repaid.

How to calculate the amount of loan that Molly needs?

Molly has a $2500 down payment saved for a purchase

The dealer's cash allowance is $1500, this will be deducted from her total

The amount of loan that Molly needs can be calculated by subtracting the dealer's cash allowance from Molly's down payment

Loan= Down payment-cash allowance= 2500 - 1500= 1000

To minimize the distance walked, and the minimum distance is 31.8% of the total circumference of the circle.

If we draw a line segment from A to B, it will intersect the circle at two points, C and D. We can find the distance AC and the distance BD by using the Pythagorean theorem.

Let r be the radius of the circle, and let x be the distance we walk in and then out of the circle.

Then, we have:

AC = √(r^2 - (x/2)^2)

BD = √(r^2 - (x/2)^2)

The total distance we walk is AC + BD + AB. Since AB is fixed, we want to minimize AC + BD.

AC + BD = 2√(r^2 - (x/2)^2)

To minimize this expression, we need to maximize the value inside the square root. That means, we need to set (x/2)^2 to be as small as possible.

In other words, we want x to be as large as possible.

The maximum value of x is the diameter of the circle, which is 2r.

If we walk in and out of the circle along the diameter, then AC and BD are both equal to r, and the total distance we walk is 2r + AB.

Therefore, the percentage of the total circumference that we walk in and out of the circle is:

2r / (2πr) * 100% = 100/π ≈ 31.8%

So, we need to walk in and out of the circle at two points that are opposite to each other, along a diameter, to minimize the distance walked, and the minimum distance is approximately 31.8% of the total circumference of the circle.
