Step-by-step explanation:
Yes, there is another exponent.
When you are multiplying exponents, you add the exponents.
So from the equation 2^6 x 2^5, you can keep the 2 the same, as this is the base:
2^11
and add the exponents (6+5)
To check:
2^6=64
2^5=32
64x32=2048
2^11=2048
So, 2^11 is equivalent to your equation. Hope this helps ;)

Celine is training to run a marathon. During her training, she kept track of how much time
she spent running on the treadmill inside and on a trail outside each week. These box plots
show the results.
Where was there more variation in the amount of time Celine spent running?
Answer:
There was more variation in her time spent running outside.
Step-by-step explanation:
This is because the range for running outside is larger.
To find range you subtract the largest number in the data by the smallest.
RANGE FOR INSIDE: 150 - 25 = 125
RANGE FOR OUTSIDE: 200 - 50 = 150
Since the range is larger for the time outside spent running, there is more variation.

11 fewer slices than he received.
how many slices did he eat
The expression for the number of slices Harris ate is [tex](n/44) - 11.[/tex]
What is the expression for slices eaten?Let s be the number of slices each friend received.
Then the total number of slices on the pizza is n and we have: 44s = n because pizza was evenly divided among the 44 friends). Harris ate 11 fewer slices than he received, so he ate s - 11 slices.
The no of slices he received is s and we have:
s = (s - 11) + Harris's slices eaten
Substituting 44s = n, we will solve for s:
44s = n
s = n/44
So, the expression for the number of slices Harris ate is [tex](n/44) - 11.[/tex]

of the figure?
12 in
18 in
A=r²
The area of the composite figure is 343.62 square inches.
What is a 3D composite shape's area?
Composite things that are three dimensional (3D) are created by joining two or more objects. Finding each object's outside surface area and adding the surface areas together will yield the surface area of a 3D composite object.
Area of rectangle = length x width = 12 x 18 = 216 sq in
As a result, the radius is equal to 9 inches, or half the diameter.
[tex]Area \ of\ semicircle = (1/2) * \pi * r^{2} \\\\Area \ of \ semicircle = (1/2) * 3.14 * 9^{2} \\\\Area \ of \ semicircle = 127.62\ sq\ in[/tex]
The combined area of the rectangle and the semicircle is therefore equal to the area of the composite figure as a whole:
Total area = 216 sq in + 127.62 sq in = 343.62 sq in

If you graph the system of inequalities given below, which points would lie in the solution set? Select all the correct answers.
x-y>-4
2x-y<5
2y + x>1
(-2,3)
(-1,3)
(0, 0)
(2,-2)
(3,5)
Answer:
To determine which points lie in the solution set of the system of inequalities x-y>-4, 2x-y<5, and 2y + x>1, we can graph the inequalities on a coordinate plane and look for the region that satisfies all three inequalities.
To graph the inequality x-y>-4, we can first graph the line x-y=-4 by plotting the points on the line:
x y
0 -4
-4 0
Then, we can shade the region above the line, since all points above the line will satisfy the inequality x-y>-4:
|
-4 | x
| /
| /
| /
|/
-8 +------
-4 0
To graph the inequality 2x-y<5, we can first graph the line 2x-y=5 by plotting the points on the line:
x y
0 5
2.5 0
Then, we can shade the region below the line, since all points below the line will satisfy the inequality 2x-y<5:
|
5 | x
| / |
| / |
| / |
|/ |
0 +----|--
0 2.5
To graph the inequality 2y + x>1, we can first graph the line 2y + x = 1 by plotting the points on the line:
x y
0 0.5
1 0
Then, we can shade the region above the line, since all points above the line will satisfy the inequality 2y + x>1:
|
2 | x
| |
1|-----
| /
| /
| /
|/
0 +------
0 1
The solution set of the system of inequalities is the region that satisfies all three inequalities, which is the shaded region in the graph below:
|

Entre que valores varía la masa corporal MC de la mayoría de estudiantes?
The majority of students have a body mass between 46.7 and 79.1 kg, and there are 36 students with a body mass of 61.7 kg or greater.
Assuming a normal distribution of body mass among the students, we can use the concept of standard deviation to answer the question. Let's assume that the mean body mass of the students is 60 kg, and the standard deviation is 5 kg.
To find the range of body mass where the majority of students fall, we can use the empirical rule, which states that for a normal distribution, approximately 68% of the data falls within one standard deviation of the mean, 95% within two standard deviations, and 99.7% within three standard deviations.
Therefore, the range of body mass where the majority of students fall is between 55 kg (60 kg - 5 kg) and 65 kg (60 kg + 5 kg).
To find the number of students with a body mass equal to or greater than 61.7 kg, we need to find the z-score of 61.7 kg, which is
(61.7 - 60) / 5 = 0.34.
We can then use a standard normal distribution table to find the proportion of the area to the right of this z-score, which is 0.3665. This means that approximately 36.65% of the students have a body mass equal to or greater than 61.7 kg.

Lucy received a $1300 bonus. She decided to invest it in a 3-year certificate of deposit (CD) with an annual interest rate of 1.27% compounded monthly.
Answer the questions below. Do not round any intermediate computations, and round your final answers to the nearest cent. If necessary, refer to the list of financial formulas.
(a) Assuming no withdrawals are made, how much money is in Lucy's account after 3 years?
$____
(b) How much interest is earned on Lucy's investment after 3 Years?
$____
Answer:
(a) $1350.46
(b) $50.46
Step-by-step explanation:
You want to know the future value of a $1300 CD earning 1.27% compounded monthly for 3 years, along with the amount of interest earned.
Future valueThe compound interest formula tells you the future value is ...
FV = P(1 +r/12)^(12·t)
where r is the annual interest rate and t is the number of years.
ApplicationUsing the given values, we have ...
FV = $1300(1 +0.0127/12)^(12·3) ≈ $1350.46
(a) The value after 3 years is $1350.46.
The interest earned is the difference between the final value and the amount of the original investment:
Interest = $1350.46 - 1300.00 = $50.46
(b) The interest earned by the CD is $50.46.

What affect does the scale factor of the dilation have on the angles, if any?
After a dilation, the angle measures remain constant, meaning that they are not affected by the scale factor of the dilation.
What is a dilation?A dilation can be defined as a transformation that multiplies the distance between every point in an object and a fixed point, called the center of dilation, by a constant factor called the scale factor.
The side lengths are changed, but the original figure and the dilated figure are similar, meaning that the angle measures remain constant, no matter the scale factor.

standard error of an estimator is not affected by the multiple choice question. population standard deviation. sample size. population size
The term that is not affected the standard error of an estimator is population size, from the provide data in options. So, option (c) is right one.
The standard error is a statistical term that used to measured the accuracy that a sample distribution represents a population by using standard deviation. The standard error(SE) is very similar to standard deviation of a distribution. Both are used to measure the spread of distribution. Higher the value SE, the more spread out your data is. In statistical way, standard error is also called standard error of mean, SEM, it represents the deviation of sample mean deviates from the actual mean of a population.
It is calculated simply by dividing the standard deviation by the square root of the sample size. That is [tex]SE = \frac{σ }{\sqrt{n}}[/tex]
where , n --> sample size

imagine that you are offered two jobs. there is a 50% chance that you will take the first job and a 40% chance that you will take the second job. assume that you cannot take both jobs. what is the probability that you will take either one job or the other job?
Answer:
The probability of taking either one job or the other job can be calculated by adding the probabilities of taking the first job and taking the second job, and then subtracting the probability of taking both jobs (since we cannot take both).
Let A be the event of taking the first job, and B be the event of taking the second job. Then, the probability of taking the first job is P(A) = 0.5, and the probability of taking the second job is P(B) = 0.4. The probability of taking both jobs is zero, since we cannot take both.
Therefore, the probability of taking either one job or the other job is:
P(A or B) = P(A) + P(B) - P(A and B)
= 0.5 + 0.4 - 0
= 0.9
So the probability of taking either one job or the other job is 0.9 or 90%

The average rate of change of each function on the interval 2 ≤ x ≤ 6 is given as follows:
f(x): -1.25.g(x): -0.715.How to obtain the average rate of change?The average rate of change of a function is given by the change in the output of the function divided by the change in the input of the function. Hence we must identify the change in the output, the change in the input, and then divide then to obtain the average rate of change.
For the function f(x), we have that:
When x = 2, y = 7.When x = 6, y = 2.Hence the rate is given as follows:
r = (2 - 7)/(6 - 2)
r = -5/4
r = -1.25.
For the function g(x), we have that:
When x = 2, y = 2(-5/7) - 6 = -7.43.When x = 6, y = 6(-5/7) - 6 = -10.29.Hence the rate is given as follows:
r = (-10.29 - (-7.43))/(6 - 2)

Historically, your company has calculated bad debts using an aging of accounts receivable. Near the end of the fiscal year, the company is in a cash crunch and needs to borrow money from the bank, using accounts receivable as collateral. The owner of the company knows that many of the accounts receivable are more than 90 days past due, resulting in net receivables equal to only 80% of total receivables. Respond to the following in a minimum of 175 words: The owner asks you to change the method of estimating bad debts to a flat 3% of receivables. What should you do?
If owner asks you to change the method of estimating bad debts to a flat 3% of receivables, then you should carefully "evaluate request to change method of estimating bad-debts", "use prudent and analytical approach" and to communicate effectively with stake-holders.
As a "financial-advisor" for company, it is important to consider request of owner to change method of estimating "bad-debts" to a flat 3% of receivables, given the circumstances described.
(i) It is crucial to understand the reasons behind change in method of estimating bad debts.
In this case, the company is facing a "cash-crunch" and needs to borrow money from the bank, using accounts receivable as collateral.
The owner is aware that many of "accounts-receivable" are more than 90 days past-due, which results in net receivables equal to only 80% of total receivables,
It indicates that company is experiencing a higher level of delinquency in its accounts receivable, and the owner may be seeking a more conservative estimate of bad debts to reflect this situation.
(ii) A more prudent approach would be to conduct a thorough analysis of the company's accounts receivable, considering factors such as the aging of accounts, historical collection patterns, industry norms, economic conditions, and creditworthiness of customers.
This help in developing a more accurate and reliable estimate of bad debts that aligns with the company's specific circumstances.
(iii) it is important to communicate-effectively with owner and other relevant stakeholders, explaining reasons behind recommended method of estimating bad debts and the potential implications of using a flat percentage.
This can help in building transparency, trust, and confidence in the financial reporting process and decision-making of the company.
