An ice cream shop has 10 flavors and one can choose 4 different flavors. The question asks for the total number of possible flavor combinations.Therefore, we need to find the number of ways in which 4 flavors can be chosen from 10 flavors.

In such cases where order does not matter and repetitions are not allowed, we can use the formula for combinations which is as follows:C(n, r) = n! / (r! (n - r)!)Where n is the total number of items, r is the number of items being chosen at a time and ! represents the factorial function.

Using this formula we can find the total number of possible flavor combinations. Substituting the values in the above formula, we get:C(10, 4) = 10! / (4! (10 - 4)!)C(10, 4) = (10 * 9 * 8 * 7) / (4 * 3 * 2 * 1)C(10, 4) = 210Hence, there are 210 possible flavor combinations when one can choose 4 different flavors

.Explanation:The formula to be used for this type of question is combination. Combination is the method of selecting objects from a set, typically without replacement (without putting the same item back into the set) and where order does not matter. The formula for combination is given by C(n,r)=n!/(r!(n-r)!).

Answer:

The area of the given triangle is 10 sq meters

Explanation:

The area of a triangle is given by the formula:

Area = 1/2 base . height

Given that the triangle has base = 10m, and height = 2m

Area = 1/2 * 10 * 2

= 10 square meters

Answer:

x≤ -2

Step-by-step explanation:

we want black part, so we know it's going to be to the left of -2.

the black dot at -2 means we include -2. if it was just an unfilled dot (circle) we exclude -2 (ie it would just be ( < -2)

so answer is x≤ -2

The Original Price = 547

What is Original Price?

The complete cost of purchasing an asset is known as the original cost. When calculating an asset's original cost, all of the costs associated with buying and using the asset are taken into account.

Given,

Discounted Price = $328

Discount = 40%

Let original price be 100% as the percentage

Then 100% - 40% = 60%

= $328 is 60% of what number?

let what no be x

= $ 328 = 0.60*x

= $ 328 / 0.60 = 0.60/0.60 n

n = $ 328/0.60

n = 547

So, the original Price will be 547

The postfix expression of "7+5-3*2(6*7)/4" is "7 5 + 3 2 * 6 7 * 2 * - 4 /". Evaluating the postfix expression gives the result of the expression. The prefix expression for the given infix expression is "/ - + 7 5 * 3 * 2 ( * 6 7 ) 4".

To convert the infix expression "7+5-3*2(6*7)/4" into postfix expression, we follow the rules of operator precedence and associativity. The postfix expression is obtained by placing operators after their operands.

The postfix expression for the given infix expression is:

"7 5 + 3 2 * 6 7 * 2 * - 4 /"

To evaluate the postfix expression, we use a stack data structure. We scan the postfix expression from left to right and perform the corresponding operations.

Starting with an empty stack, we encounter the operands "7" and "5". We push them onto the stack. Then we encounter the operator "+", so we pop the last two operands from the stack (5 and 7), perform the addition operation (7 + 5 = 12), and push the result back onto the stack.

We continue this process for the remaining operators and operands in the postfix expression. Finally, after evaluating the entire expression, the result left on the stack is the final answer.

To convert the infix expression into prefix expression, we follow similar rules but scan the expression from right to left. The prefix expression is obtained by placing operators before their operands.

The prefix expression for the given infix expression is:

"/ - + 7 5 * 3 * 2 ( * 6 7 ) 4"

The approximate surface areas of corresponding prisms are listed below:

The surface area of the each figure (\(A\)), in square units, is equal to the sum of the surface area of the two bases (\(A_{b}\)), in square units, and the surface areas of the lateral sides (\(A_{l}\)), in square units. Since bases are regular polygons, base surface area can be determined by this expression:

\(A_{b} = \frac{l^{2}\cdot n }{4\cdot \tan \frac{180}{n} }\)  (1)

Where:

The area of one lateral side is expressed by this expression:

\(A_{l} =h\cdot l\)   (2)

Where h is the height of the rectangle, in units.

The total surface area is defined by the following formula:

\(A = 2\cdot A_{b} + n\cdot A_{l}\)   (3)

Now we proceed to calculate each surface area:

\(A = 2\cdot \left[\frac{2^{2}\cdot (6)}{4\cdot \tan \left(\frac{180}{6} \right)} \right]+6\cdot (2)\cdot (9)\)

A = 108.136 units²

\(A = 2\cdot \left[\frac{(4\sqrt{3})^{2}\cdot (3)}{4\cdot \tan \left(\frac{180}{3} \right)} \right]+3\cdot (4\sqrt{3})\cdot (9)\)

A = 228.631 units²

\(A = 2\cdot \left[\frac{6^{2}\cdot (5)}{4\cdot \tan \left(\frac{180}{5} \right)} \right]+5\cdot (6)\cdot (11)\)

A = 453.874 units²

the correct choice is {0, 18}. These elements are unique to set C and do not appear in set A.

To find the set difference C - A, we need to remove all elements from A that are also present in C. Let's examine the sets:

C = {0, 6, 12, 18}

A = {2, 4, 6, 8, 10, 12}

We compare each element of A with the elements of C. If an element from A is found in C, we exclude it from the result. After the comparison, we find that the elements 2, 4, 8, 10 are not present in C.

Thus, the set difference C - A is {0, 18}, as these are the elements that remain in C after removing the common elements with A.

Therefore, the correct choice is {0, 18}. These elements are unique to set C and do not appear in set A.

The correct answer is option  c. Interval. The level of measurement for the data set described is Interval.

This is so because the data set calculates each student's enrollment in classes during the course of a semester at a particular college.

Numerical information that is measured on a scale with evenly spaced intervals but lacks an absolute zero point is called interval data.

The numerical values themselves do not reflect quantities or have any absolute value, but the intervals between them all have the same size.

The interval between 3 classes and 4 classes, for instance, would be the same as the interval between 8 classes and 9 classes if the data set were measuring the number of classes each student took in a semester, but 3 classes and 8 classes do not have any such absolute value.

The correct answer is A. 600 nautical miles is not the distance you will cover when traveling south along the 180° longitude from 5°N to 5°S. The correct distance is 0 nautical miles since the points are on the same line of longitude.

The distance traveled along a line of longitude can be calculated using the formula:

Distance = (Latitude 1 - Latitude 2) * (111.32 km per degree of latitude) / (1.852 km per nautical mile)

Given:

Latitude 1 = 5°N

Latitude 2 = 5°S

Substituting the values into the formula:

Distance = (5°N - 5°S) * (111.32 km/°) / (1.852 km/nm)

Converting the difference in latitude from degrees to minutes (1° = 60 minutes):

Distance = (0 minutes) * (111.32 km/°) / (1.852 km/nm)

Simplifying the equation:

Distance = 0 * 60 * (111.32 km/°) / (1.852 km/nm)

Distance = 0 nm

Therefore, traveling south along the 180° longitude from 5°N to 5°S, you will cover approximately 0 nautical miles.

The measure of arc BED is:

180 degrees

The arc of a circle is the segment or part of the circumference of a circle. The measure of an arc is the angle at which the arc is subtended.

You will notice that AD is the diameter of the circle.

Since the measure of arc CD is 90°.

Thus, the measure of arc AB is:

90 - 52 =  38°

Arc ED = arc AB (vertically opposite angles are equal)

Therefore, the measure of Arc BED will be:

Arc BED = Arc BC + arc CD + arc ED

Arc BED = 52° +  90° +  38°

Arc BED = 180°

After converting from Celsius to Fahrenheit , we will get 54 Celsius is equivalent to 129.2 Fahrenheit.

To convert Celsius to Fahrenheit, you can use the following formula:

°F = (°C x 9/5) + 32

In this case, to convert 54 Celsius to Fahrenheit, we can substitute 54 for °C in the formula:

°F = (54 x 9/5) + 32

Simplifying this expression, we can first perform the multiplication and division:

°F = (97.2) + 32

Then we can add 97.2 and 32 to get the final answer:

°F = 129.2

It's worth noting that the Celsius and Fahrenheit scales are both used to measure temperature, but they have different starting points and different degrees of scale. Celsius is based on the freezing and boiling points of water, where 0 degrees Celsius is the freezing point and 100 degrees Celsius is the boiling point at sea level.

Fahrenheit, on the other hand, is based on a system of degrees devised by Gabriel Fahrenheit, with 32 degrees being the freezing point and 212 degrees being the boiling point at sea level.
