The equation, 2(x + 8) = 2x + 8 has no solution because 16 = 8.

To solve an equation, you find the value of the variable that makes the equation true. This can involve using inverse operations (such as addition and subtraction, multiplication and division, or exponentiation and logarithms) to isolate the variable on one side of the equation, and then using properties of equality to simplify the equation.

Given the following, 2(x + 8) = 2x + 8:

Step 1: Distribute 2(x + 8) = 2x + 8 to get 2x + 16 = 2x + 8

Step 2: Subtract 2x from both sides to get 16 = 8

2x + 16 = 2x + 8

2x + 16 - 2x = 2x + 8 - 2x

the amount that results from the given investment $500 invested at 12% compounded quarterly after a period of 3 years is:  $711.66. This can be solved using the concept of compound interest.

When calculating compound interest, the starting principle amount is multiplied by one together with the yearly interest rate raised to the number of compound periods minus one. The resultant value is then reduced by the whole initial loan amount. When you earn interest on your interest earnings as well as the money you have saved, this is known as compound interest. Compound interest accelerates the growth of your money since it calculates interest on both your original principle and the interest that has accrued over time. The initial investments and the revenue generated by those investments increase simultaneously as a result of compounding, which can have a snowball effect.

Principal amount (P) = $500

interest rate (r) = 12%

time (t) = 3 years

period (n) = 3

Final amount = A

As we know, A = P ( 1 + r/n) ^{nt}

or, A = 500 (1 + 0.12 / 3)^{3*3}

If we randomly choose a point on which Federer served and get distracted before seeing his first serve but look up in time to see Federer win the point , then the probability that he missed his first serve given he won the point is (a) 0.3000

To calculate the probability that Federer missed his first serve given that he won the point, we Let , event A is = Federer missed his first serve and

event B is = Federer won the point.

So, probability of Federer missing his first serve = (100-63)% = 37% = 0.37,

probability of Federer winning point given he missed his first serve= 57%.

⇒the probability he first serve and misses point = (0.37)(0.57) = 0.2109  .

The probability of Federer winning the point, regardless of whether he made his first serve or not, can be calculated as

⇒ (0.63)(0.78) + (0.37)(0.57) = 0.7023  .

Let's consider the first roll "a". The second, third, and fourth rolls will be represented as "b", "c", and "d".

The first roll of a can be any integer from 1 to 6.

For the second roll of b, there are 5 possible integers that are greater than or equal to the first roll "a".

For the third roll of c, there are 4 possible integers that are greater than or equal to the subsequent roll "b".

For the fourth roll of d, there are 3 possible integers that are greater than or equal to the third roll "c".

Thus, the total number of possible outcomes that meet the rules is 6 * 5 * 4 * 3 = 360.

The total number of possible outcomes for rolling a fair die multiple times is 6 * 6 * 6 * 6 = 1296.

This is how the probability of every one of the last three rolls being in some measure as extensive as the roll going before it is 360/1296, which can be improved to 5/18.

Answer:

The range is the difference between the largest and smallest values in a set of data. In this case, the heights of the 11 plants are listed as:

14, 15, 15, 16, 16, 16, 17, 17, 18, 19, 20

The smallest height is 14 inches and the largest height is 20 inches, so the range is 20 - 14 = 6 inches.

If another plant with a height of 17 inches is added to the data, the smallest and largest values do not change, so the range would still be 6 inches.

Answer:

Answer to the question posted: The range would stay the same value of 6 inches.

Answer to the question in the comments: The mean would decrease in value to about 16.8 inches.

Step-by-step explanation:

Answer to the question posted:

First, to figure out if the range increases, decreases, or stays the same, we need to find the range. The range is siply the difference between the largest ans smallest number. In this problem, the smallest plant height is 14 while the largest plant height is 20. Since the difference between the smallest and largest plant is 20-14, or 6, inches, the range is 6 inches.

Now, let's figure out what would happen if we added a plant with a height of 17 inches. Well, since our smallest plant height and largest plant height would not be changed, the range would stay the same value of 6 inches.

Answer to the question in the comments:

The first step is to find the mean of the plant heights. To find mean, you need to add up all the plant heights and divide it by the number of plants. Since 13+14+15+15+16+16+16+17+17+18+19+20+22+23=241 and there are 14 plants, we can divide 241 by 14 to find the original mean of the plant heights. When we solve 241/14, we get 17.2142857143.

Now, let's figure out what would happen to the mean if we added a plant with a height of 11 inches. Again, we would need to total up all the plant heights, and it should be 11 inches larger than last time, as we are adding 11 inches to the total plant height. Since our original total height was 241, or new total height, adding in the 11 inch plant, would be 252 inches. Now that we have our total plant height including the 11 inch plant, we need to figure out how many total plants we have. If we started with 14 plants and add another plant into the data set, then the total number of plants, including the 11 inch plant, must be 15. Now that we know the new total plant height and new amount of plants, we can find the new mean, The new mean is 252/15, or 16.8.

So, if our mean went from 17.2142857143 to 16.8 when we added the 11 inch plant, the mean would decrease in value to about 16.8 inches.

The J (Jenny) has $15 , C (Charlie) has $20 and A(Aldo) has $30 in their wallets with total sum of $65.

Since Jenny, Charlie and Aldo have a total of $65 in their wallets. This could be represented as

J + C + A = 65      (equation 1)

Jenny has $5 less than Charlie

J = C - 5         (equation 2)

Aldo has 2 times what Jenny has

A = 2 * J   (equation 3)

Now we can solve the above equations by substitution.

Rearranging Equation 2 as

C = J + 5

Now substituting the values of A and C in equation 1 from 2 and 3. So equation 1 would become

J + (J+5) + (2*J) = 65

Solving the above equation

J + J + 5 + 2J = 65

4J = 65-5

4J = 60

J = 60/4

J = 15

Now if we insert the value of J in equation 2 and 3 we will get C and A.

C = J + 5

C = 15 + 5

C= 20

And

A = 2*J

A= 2*15

A = 30

The J (Jenny) has $15 , C (Charlie) has $20 and A(Aldo) has $30 in their wallets with total sum of $65.

the daily balance equals the previous day's balance plus new purchases minus the payments and credits

New purchases included indicates that at the conclusion of each day, the firm adds any new purchases to the balance. In other words, the daily balance is equal to the previous day’s amount plus any new purchases less any payments or credits. Credit card issuers will also impose a late fee if payment is not received by the due date.

The daily balance approach calculates your finance fee based on your actual amount on each day of your billing cycle rather than an average of your balance throughout the course of the billing cycle. Finance costs are computed by adding each day’s amount and multiplying it by the daily rate, which is 1/365th of your APR.
