When you are dealing with a problem like this how do you solve it to make sure that the exponent is positive?
14 to the -4 power times 14 to the 7 power. I know that we will keep the base because they are the same but do I add or subtract the exponents?
Answers
Answer:
All you need to remember is the rules
Step-by-step explanation:
Let us remember
a to the m power x a to the nth power is = a to the m+n power. (add the exponents)
And
a to the m power ÷ a to the nth power is = a to the m-n power. (subtract the exponents) So
14 to the -4 power x 14 to the 7 power= 14 to the -4+7 which is equal to 14 to the 3rd power

Answers
When we measure a ECG waveform the large boxes represents 0.2 seconds.
To determine the measurements of the big box on ECG paper, we need to consider the standard calibration of ECG paper.
In most ECG papers, the standard calibration is as follows:
The horizontal distance (width) of a big box is typically 0.20 seconds.The vertical distance (height) of a big box is typically 0.5 millivolts (mV).
These measurements allow for accurate interpretation of the ECG waveform and analysis of heart activity.

Answer:
D) 116
Step-by-step explanation:
Supplementary angles add up to 180°
∠CDE + ∠FDE = 180
3x + 10 + 6x + 8 = 180
3x + 6x + 10 + 8 = 180
Combine like terms,
9x + 18 = 180
Subtract 18 from both sides,
9x = 180 - 18
9x = 162
Divide both sides by 9
x = 162 ÷ 9
\(\sf \boxed{\bf x = 18}\)
∠FDE = 6x + 8
= 6*18 + 8
= 108 + 8

Marcia makes jewelry to sell at the artists' fair. She spends $120 to rent a stall at
the fair for the day and each piece of jewelry costs Marcia $15 in materials.
Which equation would compute the number of pieces of jewelry Marcia must sell at
the artists' fair such that the average cost per piece of jewelry would be $20?
110
Answers
The equation that can be used to compute the number of pieces of jewellery is ($120 + $15q)/q = $20 .
What is the equation?
Average cost is total cost divided by the quantity of jewellery sold.
Average cost = total cost / quantity
Total cost is the sum of fixed cost and variable cost.
Total cost = fixed cost + variable cost
The fixed cost is the cost of renting the stall. The variable cost is the cost of the materials.
Total cost = $120 + ($15 x q)
T = $120 + $15q
Average cost = ($120 + $15q)/q = $20

A simple random sample of 500 elements generates a sample proportion p= 0.81. Provide the 90% confidence interval for the population proportion (to 4 decimals). b.Provide 95% the confidence interval for the population proportion (to 4 decimals).
Answers
a) The 90% confidence interval for the population proportion is approximately (0.7777, 0.8423).
b) The 95% confidence interval for the population proportion is approximately (0.7737, 0.8463).
To calculate the confidence intervals for the population proportion, we can use the formula:
Confidence Interval = sample proportion ± margin of error
The margin of error can be calculated using the formula:
Margin of Error = critical value * standard error
where the critical value is determined based on the desired confidence level and the standard error is calculated as:
Standard Error = \(\sqrt{((p * (1 - p)) / n)}\)
Given that the sample proportion (p) is 0.81 and the sample size (n) is 500, we can calculate the confidence intervals.
a. 90% Confidence Interval:
To find the critical value for a 90% confidence interval, we need to determine the z-score associated with the desired confidence level. The z-score can be found using a standard normal distribution table or calculator. For a 90% confidence level, the critical value is approximately 1.645.
Margin of Error = \(1.645 * \sqrt{(0.81 * (1 - 0.81)) / 500)}\)
≈ 0.0323
Confidence Interval = 0.81 ± 0.0323
≈ (0.7777, 0.8423)
Therefore, the 90% confidence interval for the population proportion is approximately (0.7777, 0.8423).
b. 95% Confidence Interval:
For a 95% confidence level, the critical value is approximately 1.96.
Margin of Error = \(1.96 * \sqrt{(0.81 * (1 - 0.81)) / 500)}\)
≈ 0.0363
Confidence Interval = 0.81 ± 0.0363
≈ (0.7737, 0.8463)
Thus, the 95% confidence interval for the population proportion is approximately (0.7737, 0.8463).

Answers
P-value =0.0108 , The true mean stay is longer than 4 days.
AS per the details given in the above question are as follow,
The details are,
The random sample size of patient n=28
The sample sample mean time \($=\bar{x}=4.6$\)
The sample standard deviation is S.D. \($=S=1.3$\)
Where \($\alpha=0.05$\)
Degree of freedom =n-1
Substitute the value in above equation we get,
Degree of freedom =28-1=27.
Point estimate = n - α
substitute the value in above question we get,
Point estimate=1.3- 0.5 = 0.6
Standard error= sample standard deviation/ sample mean^α
Standard error=0.246
Test statistic = Point estimation / Standard error
Test statistic = 2.442
Critical value for right trailed = T. Inv(Level of significance X Point estimation)
Critical value for right trailed = 1.703
P value for right trailed = T. Div (Level of significance X Degree of freedom)

Answers
The estimated 95% confidence interval for the mean is [10.4, 13.6], making answer choice (a) correct.
To estimate the 95% confidence interval for the mean, we can use the formula
CI = X ± t(α/2, n-1) * (s/√n)
where X is the sample mean, s is the sample standard deviation, n is the sample size, t(α/2, n-1) is the t-value for the given confidence level and degrees of freedom, and α is the significance level (1 - confidence level).
For a 95% confidence interval with 15 degrees of freedom (n-1), the t-value is approximately 2.131.
Plugging in the values, we get
CI = 12 ± 2.131 * (3/√16)
CI = 12 ± 1.598
CI = [10.402, 13.598]
Therefore, the closest answer choice is (a) [10.4, 13.6].

Jake's parents want $100,000 at the end of 40 years. They put their money in an account that yields 4% per year compounded continuously. How much money should jakes parents deposit?
Answers
Answer:
$ 20,189.65
Step-by-step explanation:
Jake's parents want $100,000 at the end of 40 years. They put their money in an account that yields 4% per year compounded continuously. How much money should jakes parents deposit?
From the above question, we are to find the Principal. The formula for Principal compounded continuously =
P = A / e^rt
Where:
A = Amount after time t = $100,000
r = Interest rate = 4%
t = Time in years = 40 years
First, convert R percent to r a decimal
r = R/100
r = 4%/100
r = 0.04 per year,
Then, solve our equation for P
P = A / e^rt
P = 100,000.00 / e ^(0.04×40)
P = $ 20,189.65
Therefore, the amount Jake's parents should invest = $ 20,189.65

Ali has hired mark and alexis to work for his shipping company. mark can load a truck with packages in 120 minutes. alexis can load the same number of packages in 240 minutes. if mark and alexis work together on a particular truck, they can load all of the packages in___minutes.
Answers
If mark and Alexis work together on a particular truck, they can load all of the packages in 90 minutes.
It will take 90 minutes for both Mark and Alexis to load all of the products.
Given,
that Mark can load a truck with items in 120 minutes and Alexis can do the same in 240 minutes, the average time for the two of them is as follows:
Average = (120 + 240) ÷ 2
= 360 ÷ 2
= 180
In this case, the term "Average" refers to the value that should be used to represent the sample. By dividing the total number of values in a particular set by the sum of all the values in that set, the average is determined. also known as the arithmetic mean.
Since there were two parties engaged, our calculation is 180 ÷ 2 = 90.
Hence, in this case, it is concluded that the correct answer is option B. 90 minutes.
