Which of the following options would guarantee a simple random sample? asking the first 50 employees who come to work on Monday morning to take the survey telling the managers in each of the 5 departments to randomly select 10 people to take the survey giving each employee a unique number from 1 to 250 and randomly selecting 50 people to take the survey sending an email to all 250 employees asking them to complete the survey within the next couple of days
Answer:
b
Step-by-step explanation:
Among all the given options, the one that would guarantee a simple random sample is: “telling the managers in each of the 5 departments to randomly select 10 people to take the survey.” Hence, Option B is correct.
What is a random sample?An unprejudiced portion of a population is chosen in a simple random sampling. With this sampling technique, the possibility of selection bias is reduced because every person of the population has an exact equal probability of being chosen.
A simple random sample is a group of people chosen at random, all with the same probability, from a larger group of people in statistics. It involves a method of randomly choosing a sample.
Random sampling assures that the results of sample should be close to those that would have been found if the complete population had been measured. With the simplest random sample, each unit in the population has an equal probability of being chosen.
Therefore, Option B is correct.

Step-by-step explanation:
Juan jogs each day from his house to a local park, and then he jogs back along the same route. On his way to the park, he averages 4 miles per hour. On his way home, he averages 6 miles per hour. If the total trip takes 1 and one-half hours, which equation can be used to find x, the distance in miles from Juan’s house to the park? Distance (mi) Rate (mi/hr) Time (hr) Trip to Park x 4 mph Trip to Home x 6 mph StartFraction x Over 4 EndFraction + StartFraction x Over 6 EndFraction = 1 StartFraction x Over 4 EndFraction + StartFraction x Over 6 EndFraction = 1 and one-half 4 x + 6 x = 1 and one-half 4 x + 6 x = 1
Answer:
The distance traveled equals the speed v multiplied by the time t
:
Since the speed varies, and we only know the total time, we must rewrite this as:

Jody works at the finish line and gets $36 each day he works plus $1.50 for each pair of shoes he sells. Write a function to represent the total (y) he will make in one day in relation to the number of shoes he sells.
Answer: y=36+1.50x
Step-by-step explanation:
Given: Daily wages = $36
Commission per pair of shoes he sells = $1.50
Let y= Total he will make in one day by selling x shoes .
Total earnings per day = Daily wages + Commission (Number of shoes)
y=36+1.50x
Hence, a function to represent the total (y) he will make in one day in relation to the number of shoes he sells: y=36+1.50x
Lara charges $12 per hour for babysitting. If f represents Lara's total fee after babysitting for h hours, which equations can be used to model the situation?
Answer: f= 12h , where f = Lara's total fee after babysitting for h hours.
Step-by-step explanation:
Given: Lara charges $12 per hour for babysitting.
Charge per hour = $12
Let h= Number of hours
Total charge = (Charge per hour) x (Number of hours)
If f = Lara's total fee after babysitting for h hours.
then, f= 12h
Hence, the required equation to model the situation : f= 12h

Oliver estimates the weight of of his cat to be 16 pounds. The actual weight of the cat is 14.25 pounds. What is the percent error of Oliver's estimate rounded to the nearest tenth of a percent.
Given:
Estimated weight of a cat = 16 pounds
Actual weight of that cat = 14.25 pounds
To find:
The percent error to the nearest tenth of a percent.
Solution:
We know that,
[tex]\text{Percent error}=\dfrac{\text{Estimated value - Actual value}}{\text{Actual value}}\times 100[/tex]
Using the above formula, we get
[tex]\text{Percent error}=\dfrac{16-14.25}{14.25}\times 100[/tex]
[tex]\text{Percent error}=\dfrac{1.75}{14.25}\times 100[/tex]
[tex]\text{Percent error}=0.122807\times 100[/tex]
[tex]\text{Percent error}=12.2807[/tex]
Round the percent error to the nearest tenth of a percent.
[tex]\text{Percent error}\approx 12.3[/tex]
Therefore, the percent error is 12.3%.

Michael wants tto start a garmets business. He borrowed 50000 for 5 years at 14% from his friend. The intrest is compoudee semi-annually from his friend. What is the total amount he will have to pay back to his friend?Round to the nearest cent
Answer:
98,357.57
Step-by-step explanation:
The formula to find the total amount obtained using compound interest is given as:
A = P(1 + r/n)^nt
Where:
A = Amount returned or payed back.
P = Amount borrowed = 50,000
R = Interest rate = 14% = 0.14
T = Time = 5 years
n = number of time compounded = semi annually = 2
Hence,
A = 50,000(1 + 0.14/2)^2 ×5
A = 50,000(1 +0.07)^10
A = 98,357.57
The amount he is paying back to his friend is 98,357.57.

A car enthusiast learns that a particular model of car, which costs $42,000 new, loses 25% of
its value every year. How much will the car be worth in 2 years?
If necessary, round your answer to the nearest cent.
Answer:
23 625
Step-by-step explanation:
[tex]42000 - 25\% = 31500 \\ 31500 - 25\% = 23625[/tex]
Answer:
The value of the car in 2 years will be 21,000 I believe.
Step-by-step explanation:
The car originally costs 42,000 dollars. Every year the car loses 25% of it's original value.
The first thing to do is multiply .25 by 42,000. This should give you 10,500.
(42,000)(.25) = 10,500
Next is to multiply 10,500 by 2 to cover the second year. Your answer should be 21,000.
(10,500)(2) = 21,000
Now subtract that from the original value. And you should get 21,000.
42,000 - 21,000 = 21,000
Best of Luck!
If this is not the answer then it is, $23,625.

Since there is a rise of 2 units every one unit, the slope or m = 2.
Since we know two points by observing the graph (0,0) and (3,6). m = y2-y1/x2-x1 = 6-0/3-0 = 6/3 = 2/1 = 2

The factors of expression into prime numbers is 2 and 11.
We are given that;
The expression= 22x
Now,
Factorization is the method of breaking a number into smaller numbers that multiplied together will give that original form.
To factor an expression into primes, we need to find the prime factors of each term and then write the expression as a product of those factors.
For example, 22x can be written as:
[tex]$22x = 2 \times 11 \times x$[/tex]

Brianna invested $990 in an account paying an interest rate of 9 3 4 9 4 3 % compounded continuously. Penelope invested $990 in an account paying an interest rate of 9 1 2 9 2 1 % compounded monthly. After 16 years, how much more money would Brianna have in her account than Penelope, to the nearest dollar?
Answer:
Brianna would have $177 more in her account than Penelope after 16 years.
Step-by-step explanation:
Note: There are errors in the question especially in how the interest rates are stated. These are therefore fixed before answering the question. The complete question with the fixed errors is given as follows:
Brianna invested $990 in an account paying an interest rate of 9.34943% compounded continuously. Penelope invested $990 in an account paying an interest rate of 9.12921% compounded monthly. After 16 years, how much more money would Brianna have in her account than Penelope, to the nearest dollar?
The explanation to the answers is now provided as follows:
Step 1: Calculation of the amount of money Brianna would have in her account after 16 years
Since the interest rate is compounded continuously, the amount can be calculated using the formula for calculating the future of value (FV) with a continuous compounding interest rate as follows:
FVB = Pe^(rt) …………………………. (1)
Where;
FVB = Future value or the amount of money Brianna would have in her account after 16 years = ?
P = Amount invested = $990
e = exponential function
r = interest rate = 9.34943%, or 0.0934943
t = number of years = 16
Substituting the values into equation (1), we have:
FVB = $990 * e^(0.0934943 * 16)
FVB = $990 * e^(1.4959088)
FVB = $990 * 4.46339103998695
FVB = $4,418.75712958708
Rounding to the nearest dollar, we have:
FVB = $4,419
Therefore, Brianna would have $4,419 in her account after 16 years.
Step 2: Calculation of the amount of money Penelope would have in her account after 16 years
Since the interest rate is compounded monthly, the amount is calculated using the normal formula for calculating the future value as follows:
FVP = P * (1 + R)^n …………………………. (2)
Where;
FVP = Future value or the amount of money Penelope would have in her account after 16 years = ?
P = Amount invested = $990
R = monthly interest rate = Interest rate / 12 months = 9.12921% / 12 = 0.0912921 / 12 = 0.007607675
t = number of months = number of years * 12 months = 16 * 12 = 192
Substituting the values into equation (2), we have:
FVP = $990 * (1 + 0.007607675)^192
FVP = $990 * 1.007607675^192
FVP = $990 * 4.28510670976906
FVP = $4,242.25564267137
Rounding to the nearest dollar, we have:
FVP = $4,242
Therefore, Penelope would have $4,242 in her account after 16 years.
Step 3: Calculation of the amount of money Brianna would have more in her account than Penelope after 16 years
From Step 1 above, we have:
FVB = Future value or the amount of money Brianna would have in her account after 16 years = $4,419
From Step 2 above, we have:
FVP = Future value or the amount of money Penelope would have in her account after 16 years = $2,242
The amount of money Brianna would have more in her account than Penelope after 16 years can be calculated by deducting FVP from FVB to obtain the difference as follows:
Difference = FVB - FVP = $4,419 - $4,242 = $177
Therefore, Brianna would have $177 more in her account than Penelope after 16 years.
