If there is more than one value, separate them with commas.

Answer:

A = {1,2,3,4,5}

B = {5,6,7,8,9}

========================================================

Explanation:

Consider the set

A = {1,2,3,4,5}

The mean is found by adding up all the values to get 15, then divide by the number of values (5) to get 15/5 = 3

The standard deviation is a bit more complicated, and it depends which version you select (sample vs population). Let's say we go for the population standard deviation. Using a calculator gets us a population standard deviation of roughly 1.414; this value tells us how spread out the data set is. The higher the value, the more spread out the data set will be.

Now consider adding some fixed value to each item in set A. Let's add 4 to each value

We go from A = {1,2,3,4,5} to B = {5,6,7,8,9}

If you were to use a calculator, then the population standard deviation is still roughly 1.414 but the mean is now 7. The standard deviation hasn't changed because the values are still spread out the same way.

Note: infinitely many answers are possible for sets A and B.

The number of rotations will be the ratio of the total distance traveled to the distance traveled in one rotation thus the total rotation to cover 100 inches will be 4.55.

A circle is a geometrical figure which becomes by plotting a point around a fixed point by keeping a constant distance.

The longest line which can be drawn inside the circle will be the diameter.

The number of rotations will be the ratio of the total distance traveled to the distance traveled in one rotation.

Distance traveled in one rotation = Perimeter of the wheel.

⇒ 2π(3.5) = 21.99

The number of rotations = 100/21.99 = 4.55

Hence "The number of rotations will be the ratio of the total distance traveled to the distance traveled in one rotation thus the total rotation to cover 100 inches will be 4.55".

The distance in kilometers from Sanjay's house to Carl's house is 4.55 kilometers.

According to the question,

We have the following information:

Dyna's house is 6.85 kilometers from Carl's house. Sanjay's house is 2 3/10 kilometers closer to Carl's house than Dyna's house is.

(Closer means that the distance will be [tex]2\frac{3}{10}[/tex] kilometers less than 6.85 kilometers.)

Now, converting the mixed fraction into decimal point:

23/10 = 2.3 kilometers

Now, let's take the distance from Sanjay's house to Carl's house to be x kilometers.

x = 6.85 - 2.3

x = 4.55 kilometers

Hence, the distance in kilometers from Sanjay's house to Carl's house is 4.55 kilometers.

The rate of change at which the value of the auto is -950/year.

What is the Rate of Change?

It is said that the rate at which one quantity changes in relation to another is known as the rate of change function.

In simple terms, when calculating the rate of change in one item, the amount of change in another is divided by the comparable amount of change in another.

From the given data of question,

[tex]V(t) = 24000*0.95^{t}[/tex]

Then, by definition, the rate of change =[tex]\frac{d(v(t))}{dt} = \frac{d(24000*0.95^{t} )}{dt}[/tex]

                                                                 =  [tex]24000*0.95^{t}*ln(0.95)[/tex]

For time (t) = 5 years

The school dance committee can be chosen in 1,86,70,176 ways.

Given, that  7 freshmen, 8 sophomores, 9 juniors, and 9 seniors are eligible to be on the committee.

Also, the school dance committee consist of 2 freshmen, 3 sophomores, 4 juniors, and 5 seniors

So, the number of ways in which the committee can be chosen are

C(7 , 2)×C(8 , 3)×C(9 , 4)×C(9 , 5)

On solving C(7 , 2), we get

C(7 , 2) = (7×6)/2 = 21

On solving C(8 , 3), we get

C(8 , 3) = (8×7×6)/(3×2) = 56

On solving C(9 , 4), we get

C(8 , 3) = (9×8×7×6)/(4×3×2) = 126

On solving C(9 , 5), we get

C(9 , 5) = (9×8×7×6×5)/(5×4×3×2) = 126

So, C(7 , 2)×C(8 , 3)×C(9 , 4)×C(9 , 5) = 21×56×126×126

The constant percent rate of change of the function is option (d) 55% decay

The equation of the function is given as

f(x) = 32(0.45)^x

The above function is an exponential function

An exponential function is represented as

y = ab^x

Where b represents the growth or decay factor

So, we have

b = 0.45

We can see that the value of b is less than 1

This means that the graph would represent a decay

The percent rate of change is then calculated as

Rate = 1 - b

This gives

Rate = 1 - 0.45

Evaluate

Rate = 0.55

Rewrite as

Rate = 55%

The correct option is A . 12(3+2+4) shows the greatest common factor of these three values using the distributive property

A factor is an integer in mathematics that, when multiplied by other integers, produces the desired results. The resultant total is also known as the factors. The numbers can often be combined in a broad variety of ways. If you are familiar with the multiplication tables, it will be simple for you to determine the factors.

When two or more numbers are combined, the largest number is the greatest common factor (GCF). They are divided by the biggest number, which yields a natural number (factor). There are a few things that both share once all the variables that effect the number have been identified. The term "largest common factor" refers to the common factor among the others having the highest number.

The product of the common prime factors of 2 or more numbers is the greatest common factor(GCF) of the numbers.

Using the distributive property, it can be written that  .a(b+c) = ab + ac

Step 2

Write each number as the product of its prime factors. The product of the common factors is the greatest common factor(GCF) of the numbers.

The numbers,36 , 24 , 48  can be factored as follows.

36 = 2 * 2 * 3 * 3

24 = 2 * 2 * 3 * 2

48 = 2 * 2 * 3 * 2 * 2

Hence, the greatest common factor(GCF) of these numbers is equal to  

2 * 2 * 3  or 12 .

Take out the greatest common factor(GCF), 12 from the expression,  36+24+48 using the distributive property to obtain the result.

36+24+48 = 12 * 3 + 12 * 2 + 12 * 4

                 = 12 ( 3 + 2 + 4 )

Hence, the correct option is A .

Option B is incorrect as the factored out term is 6, which is not the greatest common factor(GCF) .

Option C is incorrect as the factored out term is 4, which is not the greatest common factor(GCF) .

Option D is incorrect as the factored out term is 3, which is not the greatest common factor(GCF) .

Step-by-step explanation:

The probability for the given case is 1/3.

Probability is the branch of Mathematics that deals with the measurement of the chance of occurrence of a random event.

The probability of any event always lies in the close interval of 0 and 1 [0,1].

The probability of an event cannot be negative.

A spinner has numbers indicated on it from one to six.

Suppose A be the event spinner lannds on 1.

And, B be the event the spinner land on 4.

Now, the probability of any event is the ratio of number of favorable outcome to the total number of outcomes which is given as,

P(A) = 1/6

And, P(B) = 1/6

Thus, the probability of event A or B is given as,

P(A or B) = P(A) + P(B)

              = 1/6 + 1/6

              = 1/3

Hence, the probability that the spinner lands on 1 or 4 is 1/3.

30% of the area under the normal curve lies to the left of -0.52 z - score.

What is z - score?

The relationship between a value and the mean of a group of values is quantified by a Z-score. The Z-score is calculated using standard deviations from the mean. When a data point's Z-score is 0, it means that it has the same score as the mean.

To find the z - score, divide your data point by your standard deviation after taking your data point and subtracting the mean from it.

Here, 30% = 0.30

So,

P(Z < z) = 0.30

From z - table, z - score for the probability 0.30 is -0.5244

-0.5244 ≈ -0.52

What is the double-declining-balance method?

One of the depreciation methods in use is the double-declining-balance method, however it places more expense in the initial years of an asset's life.

The straight-line rate, which is calculated as the product of 100/estimated useful life multiplied by 2, is doubled in this depreciation technique.

The double rate is applied to the remaining balance at the end of each year for the depreciation expense.

The depreciation expense for the most recent year is calculated as the difference between the ending balance from the prior year and the residual value.

Auto  = $26,000

Estimated useful life = 10 years

Residual = $600

Depreciable amount = $26,000 - $600 = 25,400

Straight-line depreciation rate = 100/10 = 10%

Double-declining depreciation rate =10% x 2 = 20%

Depreciation Expense:

1st year = 26000 x 20/100 = 5200
