Answer:

24 / 2500

Step-by-step explanation:

Experimental probability = (number of successes / total number of trials)

For rolling :

Total number of trials = ( 10 + 4 + 8 + 11 + 8 + 9) = 50

Number of times 2 is rolled = 4

P(rolling a 2) = 4 /50

For spinning :

Total number of trials = (8 + 6 + 9 + 11 + 9 + 7) = 50

Number of times 2 is spunned = 6

P(rolling a 2) = 6 /50

Hence,

4 / 50 * 6/50 = 24 / 2500

for (-3)^4, if there were more numbers in the parentheses, the exponent would apply to all numbers in the parentheses

for -3^4, the exponent would only apply the -3.

hope this helps!

Answer:

-3^4=-81 and (-3)^4=81

Step-by-step explanation:

Following the rules of PEMDAS you will do exponents before multiplcation.

A negative sign means that you are multiplying by -1.

-3^4 means you will raise 3 to the 4th power and then multiply by -1. So you will do 3^4 first which is 81 and then multiply by -1. Making the answer -81.

When you put parentheses around the -3 it means you are raising the entire -3 to the power of 4 instead of only the 3. So it will be -3*-3*-3*-3 which is 81.

The greengrocer normally sells 20 carrots for £2.80. The new cost of 1 carrot is £0.098.

Original cost is the price of an item or service before any discounts, taxes, or other adjustments.

This means that the cost of 1 carrot is £2.80/20 = £0.14.

When the cost of the carrots is reduced by 30%, the new cost of 1 carrot is £0.14 × (100%-30%) = £0.098.

Therefore, the cost of 180 carrots in the sale is £0.098 × 180 = £17.64.

The discount of 30% reduces the cost of 1 carrot from £0.14 to £0.098, and this reduces the cost of 180 carrots from £25.2 to £17.64.

This is because a 30% discount means that the cost of the item is reduced by 30% of the original cost.

As the original cost of 1 carrot is £0.14, the new cost of 1 carrot is £0.14 × (100%-30%) = £0.098.

Answer:

C. 2/3

Step-by-step explanation:

Answer:

27

Step-by-step explanation:

taking the second digit as 'x'

as per question the first digit is 'x-5'

therefore putting this in the one, tens, hundreds form

u multiply the first digit by 10 and the second by 1

therefore,

10(x-5) + 1(x)

now you have that the 2-digit number is equal to twice the sum of the digits,

so

10(x-5) + 1(x) = 3 [ (x-5) + (x) ]

on solving

10x - 50 + x = 3 (2x - 5)

11x -50 = 6x - 15

taking 6x on the right and -50 on the left

11x - 6x = 50 - 15

5x = 35

therefore x = 7

now substituting this value we get that the number is

27

The required angle is 24.5°.

Given is a right triangle with perpendicular side 16 and the base = 35 we need to find an acute angle in it,

To find the acute angle in a right triangle given the lengths of the perpendicular side and the base, you can use the tangent function.

The tangent of an angle is defined as the ratio of the length of the perpendicular side to the length of the base side.

In this case, the perpendicular side is 16 and the base is 35.

Let's denote the acute angle as θ.

Using the tangent function, we can set up the equation:

tan(θ) = perpendicular side / base

tan(θ) = 16 / 35

To find the value of θ, we can take the inverse tangent of both sides:

θ = tan⁻¹(16 / 35)

θ = 24.5°

Hence the required angle is 24.5°.

The best description for Newton's third law is: When a passenger stepped from a boat to the shore, the boat moved away from the shore.

Newton's third law of motion states that "For every action, there is an equal and opposite reaction". In other words, if an object A exerts a force on object B, then object B will exert an equal and opposite force back on object A. This is the underlying principle behind the concept of action-reaction pairs.

For example, if you push a wall, the wall will push back on you with an equal force, but in the opposite direction. The law applies to all types of forces, including gravitational, electromagnetic, and strong and weak nuclear forces.

It's important to note that the third law only applies to interactions between two objects. If a third object is involved, the forces will not necessarily be equal and opposite.

If you have previous taxable wages of $102,000 and your current taxable wages are $1,100, your Social Security tax would be $6,324 for the previous wages and $68.20 for the current wages.

To calculate the Social Security tax, we need to know the tax rate for Social Security and the taxable wages. Let's assume the Social Security tax rate is 6.2% for both the employee and the employer.

Given that your taxable wages for Social Security purposes are $1,100, and your previous taxable wages are $102,000, we can determine the Social Security tax amount.

First, we need to calculate the Social Security tax on the previous taxable wages of $102,000. Multiply $102,000 by 6.2% (0.062) to find the Social Security tax for that amount:

Social Security tax = $102,000 x 0.062 = $6,324

Next, we calculate the Social Security tax on the current taxable wages of $1,100. Multiply $1,100 by 6.2% to find the tax amount:

Social Security tax = $1,100 x 0.062 = $68.20

Therefore, if you have previous taxable wages of $102,000 and your current taxable wages are $1,100, your Social Security tax would be $6,324 for the previous wages and $68.20 for the current wages.

The y3(t) ≠ y1(t) + y2(t), the system is not linear.

To show that the system is not linear, we need to check if it follows the properties of linearity: superposition and homogeneity.

A counter-example can help demonstrate that these properties do not hold for the given system.
System definition: y(t) = |a(t-1)|
Let's consider two arbitrary inputs a1(t) and a2(t) with their respective outputs y1(t) and y2(t):
1. y1(t) = |a1(t-1)|
2. y2(t) = |a2(t-1)|
Now let's apply the superposition principle:
a3(t) = a1(t) + a2(t)
Let's find the output y3(t) for a3(t) and check if it's equal to y1(t) + y2(t):
y3(t) = |a3(t-1)| = |a1(t-1) + a2(t-1)|
Now let's check if y3(t) = y1(t) + y2(t):
y1(t) + y2(t) = |a1(t-1)| + |a2(t-1)|
Since we cannot guarantee that |a1(t-1) + a2(t-1)| = |a1(t-1)| + |a2(t-1)| for all possible inputs a1(t) and a2(t), we can conclude that the given system is not linear.

Here is a counter-example:
Let a1(t) = 1 for all t and a2(t) = -1 for all t.
Then, a3(t) = a1(t) + a2(t) = 0 for all t.
The outputs will be:
1. y1(t) = |a1(t-1)| = |1|
2. y2(t) = |a2(t-1)| = |-1|
3. y3(t) = |a3(t-1)| = |0|
Now, let's compare y3(t) with y1(t) + y2(t):
y3(t) = 0, but y1(t) + y2(t) = 1 + 1 = 2.

In order to construct a Venn diagram for a survey, first enter the cardinality of the universal set to obtain subsequent cardinalities.

The universal set is the set of all possible outcomes, and the cardinality of a set is the number of elements in the set. Once you have the cardinality of the universal set, you can use it to calculate the cardinality of any other set in the survey.

For example, if the universal set has a cardinality of 100, and the survey asks people whether they like dogs or cats, you can calculate the number of people who like dogs by subtracting the number of people who like cats from the total number of people surveyed.

In order to construct a Venn diagram, you will need to draw two or more circles, each representing a set in the survey. The circles should be overlapping to represent the sets that have members in common.

option B is the correct answer.

The value of angle BCD is calculated by applying intersecting chord theorem, which states that the angle at tangent is half of the arc angle of the two intersecting chords.

Also this theory states that arc angles of intersecting secants at the center of the circle is equal to the angle formed at the center of the circle by the two intersecting chords.

arc AB =  m∠ACB

Hence proved  f is not one-to-one.

A function is a mathematical concept that assigns a unique output value for each input value.

In mathematical notation, a function is usually expressed as "f(x)" where "x" is the input and "f(x)" is the corresponding output. For example, a function could be defined as f(x) = x^2, which means that for any value of x, the function will calculate and return the square of that value.

Functions play a central role in mathematics and are used to model real-world phenomena and to study the relationships between variables. They are also used in computer programming to perform specific tasks, such as converting temperatures from Celsius to Fahrenheit or calculating the square root of a number.

Suppose that f is a function from S to T, where |S| > |T|. This means that there are more elements in S than there are in T.

Since f maps elements of S to elements of T, we can think of f as pairing elements of S with elements of T. However, since |S| > |T|, there will be at least two elements of S that are paired with the same element of T, and these two elements are s1 and s2.

Therefore, f is not one-to-one, as f(s1) = f(s2), meaning that two different elements of S are mapped to the same element of T.

This shows that if f is a function from S to T, where |S| > |T|, then there must exist elements s1 and s2 in S such that f(s1) = f(s2), and hence f is not one-to-one.

Step-by-step explanation:

The expression 80 / 4 is saying that you're splitting 80 into 4 equal parts.

80 / 4 = 20

Each part being 20.

Thus, you're looking for the situations where you're "splitting" 80 into 4 different things, all worth 20.

Option A.

Brady owed his mother 80, but repaid her 4. Brady is reducing his debt to his mom by 4. A good expression would be 80 - 4. You're not splitting up the debt, you're subtracting from it. Our expression doesn't fit.

Option B.

In total, the football team lost 80 yards across 4 plays. Our expression could be used here, but that would be assuming that they lost the same amount of yards (20) each play. This is unlikely, so we can't use our expression here. (E.g. they could lose 10, then 30, then 5, then 35 -- adding up to 80)

Option C.

Sam owed $80 to 4 friends, or, his $80 debt is split into 4 parts. Since he owes the same amount to each friend (all 4 parts are equal), we CAN use our expression here to find out how much he owed each friend.

Option D.

Taya received a total of 80, and divided it into 4 parts (one for each place she spent money at). Since we know she spent the same amount at each place (all parts are equal), our expression CAN be used here.

Option E.

Amanda withdrew $80 each day for 4 days. To find out the total, we'd have to multiply 80 by 4. $80 for each withdrawal, times four, as she did it 4 times. We are not splitting $80 up into parts, so our expression can't be used here.
