Answer:

it is the linear graph

Step-by-step explanation:

Step 1:  Match the questions

1.  Dividing the same base → \(\frac{x^7}{x^3}\) is an example of this and to divide exponents (or powers) with the same base, subtract the exponents.  Therefore we match this with option E

2.  Negative exponent with a fraction base → \((3)^{-3}\) is an example of this and in other words, the negative exponent rule tells us that a number with a negative exponent should be put to the denominator, and vice versa.  Therefore we match this with option H

3.  Product to a Power → \((2x)^3\) is an example of this and what we do is basically distribute out the exponent to everything inside of the parenthesis.  Therefore we match this with option B

4.  Power of 0 → \((15)^0\) is an example of this and what we do is basically say that the exponent of a number shows how many times the number is multiplied by itself. The zero property of exponents is applied when the exponent of any base is 0.  Therefore we match this with option C

5.  Negative exponent → \((\frac{3}{10})^{-4}\) is an example of this and a negative exponent is defined as the multiplicative inverse of the base, raised to the power which is opposite to the given power. In simple words, we write the reciprocal of the number and then solve it like positive exponents.  Therefore we match this with option G

6.  Power to a Power → \((x^2)^2\) is an example of this and what we do is multiply the powers by each other by doing \((x^{2*2})\) which would give us \(x^4\).  Therefore we match this with option A

7.  Multiplying the same base → \(x^5*x^3\) is an example of this and according to the exponent rule for multiplication with the same base, we simply add the powers.  Therefore we match this with option D

8.  Quotient to a Power → \((\frac{a}{b})^x\) is an example of this and when you raise a quotient to a power you raise both the numerator and the denominator to the power.  Therefore we match this with option F

Answer:

This sum is the sum of an arithmetic sequence.  There is a formula for the sum of an arithmetic sequence which can be looked up or derived by a variety of means.

A nice approach for this sequence is the following.  Notice  that the sum of first and last number in the sequence is the same as the sum of the second and second last, and also the same as the sum of the third and third last, and so on.

There are n of these pairs.  So the desired sum is n x (first number + last number).   But the first number is 1 and the last on is 2n.   Thus the desired sum is n(1 + 2n).

Consider the set {1, 2, 3, 4, ..., m} where m is some natural number, i.e. a positive whole number.

Now let's say we wanted to add everything in that set.

What we can do is write out the terms

1, 2, 3, 4, ..., m

then just underneath, we write the reverse of that set

m, ..., 4, 3, 2, 1

Here's an example of what I mean. I'll use m = 7

\(\begin{array}{|c|c|c|c|c|c|c|} \cline{1-7}1 & 2 & 3 & 4 & 5 & 6 & 7\\\cline{1-7}7 & 6 & 5 & 4 & 3 & 2 & 1\\\cline{1-7}\end{array}\)

For each column, add straight down

The third row will be nothing but 8's

\(\begin{array}{|c|c|c|c|c|c|c|} \cline{1-7}1 & 2 & 3 & 4 & 5 & 6 & 7\\\cline{1-7}7 & 6 & 5 & 4 & 3 & 2 & 1\\\cline{1-7}8 & 8 & 8 & 8 & 8 & 8 & 8\\\cline{1-7}\end{array}\)

We can see there are seven copies of '8' being added here, so the sum of all the numbers in the set {1,2,3,4,5,6,7} is 8*7 = 56. But wait, we double-counted each item when we formed the second row. So we must divide by 2 to fix the double-counting error.

Therefore, 1+2+3+4+5+6+7 = 56/2 = 28 instead.

-----------------------------

That previous example showed that adding from 1 to 7 means we have 7 copies of (1+7). In other words, 7 copies of 8 being added.

We could write that as 7(1+7)

Then divide that by 2 to fix the double-counting error.

We have 7(1+7)/2

Now imagine that we applied all of what was mentioned to the set {1,2,3,4,5,6,7,8}. Instead of 7's, we use 8's this time to get 8(1+8)/2

Then we can extend it out to the set {1,2,3,4,..., m} and we get the formula m(1+m)/2

We have m copies of (1+m) being added; hence the m(1+m). Don't forget to divide by 2 to fix the double-counting error.

-----------------------------

The key takeaway here is that summing 1+2+3+4+...+m gets us m(1+m)/2

In this case, m = 2n because we want the first 2n natural numbers.

Therefore,

m(1+m)/2

2n(1+2n)/2

n(1+2n)

n(2n+1)

represents the sum 1+2+3+...+n+...+2n

-----------------------------

Try out a value like n = 5 to find that 2n = 2*5 = 10, and,

1+2+3+4+5+6+7+8+9+10 = 55

also

n(2n+1) = 5(2*5+1) = 5*(11) = 55

Showing that the formula works for n = 5. I'll let you try other values of n.

The amount withheld in December for Social Security is $6,076, for Medicare is $1,421, and the total withheld is $7,497.

To calculate the amount withheld in December for Social Security and Medicare, we need to consider the applicable tax rates for these programs.

For Social Security, the current tax rate is 6.2% of the employee's salary, up to a certain income limit. However, for the year 2021, the Social Security tax has a wage base limit of $142,800. Since Stacey's annual salary of $98,000 is below this limit, we can assume the entire salary is subject to Social Security tax. Therefore, the amount withheld for Social Security in December would be $98,000 * 6.2% = $6,076.

For Medicare, the tax rate is 1.45% of the employee's total salary, without any income limit. Hence, the amount withheld for Medicare in December would be $98,000 * 1.45% = $1,421.

The total amount withheld in December for Social Security and Medicare would be $6,076 (Social Security) + $1,421 (Medicare) = $7,497.

To find the probability that at least two dice show the same number, we can first calculate the probability that all five dice show different numbers, and then subtract it from 1.

Step 1: Calculate the probability that all five dice show different numbers.
The first dice can show any number, so its probability is 1. For the second dice, there are 5 remaining numbers that are different from the first one, so its probability is 5/6. Similarly, the third dice has 4 remaining numbers, so its probability is 4/6, and so on.
So the probability that all five dice show different numbers is (1) x (5/6) x (4/6) x (3/6) x (2/6) = 20/216 = 5/54.

Step 2: Subtract the probability from 1 to find the probability of at least two dice showing the same number.
1 - 5/54 = 49/54.

Therefore, the probability that at least two dice show the same number is 49/54.

Answer:

Yes, it can make a right triangle.

Step-by-step explanation:

We can use the Pythagorean Theorem to determine if the sides make a right triangle.

\(a^2+b^2=c^2\)

We are given the side lengths: 5cm, 13cm, and 12 cm.

13cm is the longest, so it would be 'c'.

5cm and 12cm will be 'a' and 'b'.

Let 5 be 'a', 12 be 'b', and 13 be 'c':

\(5^2+12^2=13^2\\\\\text{Solve the Exponents:}\\ \rightarrow 5^2=25\\\rightarrow 12^2=144\\\rightarrow 13^2=169\\\\25+144=169\\\boxed{169=169}\)

5cm, 13cm, and 12 cm would make a right triangle. It satisfies the Pythagorean Theorem.

Answer:

AC is greater than BC because segment AC is the hypotenuse of right triangle ABC, and the hypotenuse is the longest side of a right triangle.

The hypotenuse is the longest side of the triangle. Side AC of the triangle is its hypotenuse, thus greater than BC (segment and angle theorem of a triangle).

A triangle is a shape with three side and angles. Its longest side is referred to as hypotenuse. And this side is usually opposite to the greatest angle. Examples of triangle include: equilateral, isosceles, acute, right angles, obtuse angle etc.

The given question shows that triangle ACB is a right angled triangle. This is because <CBY = \(90^{o}\).

So that;

<CBY + <CBA = \(180^{o}\)

Now comparing side AC with BC:

The segment and angle theorem of a triangle states that: the longest side of a triangle is always opposite to the greatest angle.

Thus, since <CBA is the greatest of the angles here, then AC is the longest side.

Therefore, the side AC is the hypotenuse of the triangle and it is greater than BC.

$261.80 Net pay

Step-by-step explanation:

340 x 0.23 =   $78.20 in taxes

$340 - $78.20 =  $261.80 Net pay

Answer:

$261.8 Is how much you take home.

Step-by-step explanation:

(* is multiply)

In order to find the percentage of a value, you multiply the value by the percent. Think of 100% as a scale of 1 to 0.00, since 100% of something has all of it's value, so 50% would be 0.5

23% of 340 is 78.2 ( 340 * 0.23)

Subtract 340 by 78.2, and you get your net pay, 261.8

Another way to do this is subtract 100% by 23%.

so 1 - 0.23= 0.77, which is how much percent of that pay you get to keep

so 340 * 0.77 = 261.8

Answer:

Question 1: Vol = 540cm^3

Question 2:

The height is 3 ft.

Step-by-step explanation:

The volume of a cube is: Vol

= length×width×height

So one cube is

3×3×3

which is 27 cm^3

There are 20 of these blocks, so times by 20.

27 × 20

= 540 cm^3

For the second question, a couple of ideas/definitions:

a rectangular prism just means a box shape, so the same volume formula works. A generic formula for all types of prisms is:

Vol = BaseArea×height

We can use this one because the question gives the BaseArea and the Volume.

Vol = BaseArea× h

60 = 20×h

Divide by 20.

3 = h

The height is 3 ft.

There are 360 black counters and 306 white counter in 20:17 ratio.

Let's denote the number of black counters by B and the number of white counters by W. We know that the ratio of black to white counters is 20:17, which means that:

B/W = 20/17

We also know that there are 54 more black counters than white counters, which means that:

B = W + 54

We can use substitution to solve for B. Substituting the second equation into the first equation, we get:

(W + 54)/W = 20/17

Cross-multiplying, we get:

17(W + 54) = 20W

Expanding the left side, we get:

17W + 918 = 20W

Subtracting 17W from both sides, we get:

918 = 3W

Dividing both sides by 3, we get:

W = 306

Now we can use the second equation to find B:

B = W + 54 = 306 + 54 = 360

Therefore, there are 360 black counters in the bag.

Using the binomial probability distribution, the probability of none of the 14 customers ordering a non-alcoholic beverage is approximately 0.000416 or 0.0416%.

We can solve this problem using the binomial probability distribution since we are interested in finding the probability of a specific number of successes (i.e., zero) in a fixed number of independent trials (i.e., 14 customers), where the probability of success (i.e., ordering a non-alcoholic beverage) is known and constant for each trial (i.e., 0.55).

The formula for the binomial probability distribution is:

P(X = k) = (n choose k) * p^k * (1 - p)^(n - k)

where:

P(X = k) is the probability of getting k successes in n trials

(n choose k) is the binomial coefficient, which represents the number of ways to choose k items from a set of n items, and is calculated as n! / (k! * (n - k)!)

p is the probability of success in each trial

(1 - p) is the probability of failure in each trial

Using this formula, we can calculate the probability of none of the 14 customers ordering a non-alcoholic beverage as follows:

P(X = 0) = (14 choose 0) * 0.55^0 * (1 - 0.55)^(14 - 0)

= 1 * 1 * 0.45^14

≈ 0.000416

Therefore, the probability that none of the 14 customers will order a non-alcoholic beverage is approximately 0.000416, or 0.0416% (rounded to four decimal places).

Mr. Harbin would consume 3 3/4 gallons of gas during a five-day work week based on his daily gas usage of 3/4 gallon. The correct option is

3 3/4.

To calculate how much gas Mr. Harbin would use in a five-day work week, we need to calculate the total gas consumption for each day and then add them together.

Since Mr. Harbin uses 3/4 of a gallon of gas each day, the total gas consumption for one day is 3/4 gallon.

For the gas consumption for five days, we multiply the daily consumption by the number of days:

(3/4 gallon/day) * 5 days = 15/4 gallons

To simplify the fraction, we can convert 15/4 to a mixed number:

15/4 = 3 3/4

Therefore, Mr. Harbin would use 3 3/4 gallons of gas in a five-day work week.

In summary, the answer is 3 3/4. Mr. Harbin would consume 3 3/4 gallons of gas during a five-day work week based on his daily gas usage of 3/4 gallon.

A) x = 10

B) x = 12

C) x = 15

D) x = 30

Answer:

The quantity is X= 12

The solution is 12+ ¼(12)= 15

Step by step Explanation

Problem number 26 states " "

The question above can be represented as this,

x + ¼x = 15

Here we want to find the value of x in such a way that when that value is substitute in the expresion we have 15 as our answer,But here we can perform some manipulation, by saying

4/4x + ¼x = 15 ..............eqn(1)

Even with this we can still get the above expression by saying

4/4x= x which means we're still correct.

Then the expresion eqn(1) can simplified as

5/4x = 15

If we multiply both sides by 4/5 we have

=(5/4x)×(4/5)

= 15×(4/5)

= (15/1)×(4/5)

X= 60/5

X = 12

The quantity is X= 12 and the solution is
