We can simplify the fraction by dividing both numbers by 4 (or by 2 two times), we will get the equivalent fraction 19/18
How to simplify the quotient?Here we have a quotient (or we can also call it a fraction) which is:
76/72
To simplify any fraction, what you need to do is divide both numerator and denominator by the same number.
For example, if we use 2, we will get:
76/2 = 38
72/2 = 36
then we have the equivalent fraction.
38/36
But we can keep simplifying this, divide by 2 again:
38/2 = 19
36/2 = 18

3.1.2) Determine the Accumulated amount for the investment at FNB.
3.1.3) Use the information you worked out to help Lebo decide which bank will give her the better investment. Explain your answer.
1. The accumulated amount for the investment at CAPITEC is R36,750.
2. The accumulated amount for the investment at FNB is R33,480.
3. Lebo will earn more interest if she invests her money at Capitec than at FNB.
What is the Accumulated amount for the investment at CAPITEC?The accumulated amount for the investment at Capitec with a principal amount of R30,000 invested at a simple interest rate of 7.5% for 3 years can be calculated as follows:
[tex]= Principal + (Principal * Rate * Time)\\= R30,000 + (R30,000 * 0.075 * 3)\\= R30,000 + R6,750\\= R36,750[/tex]
What is the Accumulated amount for the investment at FNB?The accumulated amount for the investment at FNB with a principal amount of R30,000 invested at a compound interest rate of 3.5% per annum for 3 years can be calculated using the compound interest formula:
[tex]= Principal * (1 + Rate)^Time\\= R30,000 * (1 + 0.035)^3\\= R30,000 * 1.116\\= R33,480[/tex]
Now, based on the calculations, the investment at Capitec will yield R36,750 after 3 years while the investment at FNB will yield R33,480 after 3 years. Therefore, Lebo will earn more interest if she invests her money at Capitec than at FNB.

solve problems 3 and 4 in homework 2 by constructing confidence intervals about the parameters to be tested, rather than performing hypothesis testing. do you get the same results as before?
Confidence intervals provide more information than hypothesis tests as they give an estimate of the parameter value as well as a range of plausible values, whereas hypothesis tests only give a decision about the null hypothesis.
To solve problems 3 and 4 in homework 2 by constructing confidence intervals about the parameters to be tested, rather than performing hypothesis testing, we need to take the following steps:
Step 1: Calculate the sample mean and sample standard deviation from the given data.
Step 2: Calculate the standard error (SE) using the formula: SE = σ / √n`,
where `σ` is the population standard deviation (if known), or the sample standard deviation (if population standard deviation is unknown)
and `n` is the sample size.
Step 3: Calculate the margin of error (ME) using the formula: `ME = z * SE`,
where `z` is the z-score corresponding to the desired level of confidence.
Step 4: Calculate the confidence interval (CI) using the formula: `CI = sample mean ± ME.
Step 5: Interpret the confidence interval in the context of the problem.
Statement: Do you get the same results as before.
No, we do not get the same results as before.
When we construct a confidence interval, we obtain a range of plausible values for the parameter with a certain level of confidence, whereas in hypothesis testing, we either reject or fail to reject the null hypothesis based on the sample data at a certain level of significance.

4) Tom has ran 10 miles of a 75 mile running challenge. If he runs 4 miles each day until he finishes the challenge, write an equation that can be used to find the number of days, d, it will take Tom to finish running the challenge miles.
Step-by-step explanation:
Let's use d to represent the number of days it will take Tom to finish the challenge miles.
Since Tom is currently 10 miles into the challenge and plans to run 4 miles each day until he finishes, the total number of miles he will run is 75 - 10 = 65 miles.
If he runs 4 miles each day, we can use the equation:
total distance = distance per day * number of days
to find the number of days it will take Tom to run 65 miles. Plugging in the known values, we get:
65 = 4d
Simplifying this equation, we can solve for d:
d = 65/4
So, it will take Tom d = 16.25 days to finish the running challenge if he runs 4 miles each day. However, since he cannot run a fraction of a day, we can round up the answer to the nearest whole number of days. Therefore, it will take Tom 17 days to finish the challenge.
The equation that can be used to find the number of days, d, it will take Tom to finish running the challenge miles is:
d = ceil(65/4)
where ceil is the ceiling function, which rounds up the result to the nearest whole number.
Answer:
16 days + 1 mile

_______ is/are formed immediately after the union of sperm and ovum in the fallopian tube.
A Zygote is/are formed immediately after the union of sperm and ovum in the fallopian tube.
What is a zygote?A zygote is a cell formed when two gamete cells are fused by means of sexual reproduction. These cells contain a single set of chromosomes from both the father and the mother of the offspring. As a result, the zygote contains all of the genetic information required to create a completely new person. After the fertilization of the ovum by the sperm, the zygote is formed. The zygote will continue to divide into a multicellular embryo and eventually a fetus after fertilization has taken place.
The fusion of a sperm cell with an ovum in the fallopian tube leads to the formation of a zygote, which involves the combination of genetic material from both parents resulting in the creation of a single-celled zygote. This zygote then initiates the process of cell division and progresses into an embryo.

analysis of a pert problem shows the estimated time for the critical path to be 108 days with a variance of 64. there is a .90 probability that the project will be completed before approximately day: group of answer choices 108. 98. 115. 118. 109.
There is a .90 probability that the project will be completed before approximately day 118.
The given information can be solved by using the formula of z-score as follows:
Z = (X - μ)/σ
Where: Z = z-score
X = the time for project completion
μ = the mean time for the critical path
σ = standard deviation for the critical path
σ² = variance of the critical pathσ = √64
σ = 8
Given that the mean time for the critical path is μ = 108 days and σ = 8 days,
Therefore, the z-score of the completion of the project before 108 days is given by:
Z = (X - μ)/σ0.90
= P(Z < z)
= P(Z < (X - 108)/8)P(Z < (X - 108)/8)
= 0.90
Using a z-table or calculator, we find the z-value to be 1.28.
Then,1.28 = (X - 108)/8
Multiplying both sides by 8, we get:10.24 = X - 108
Adding 108 to both sides, we get: X = 118.24

Which of these investments would be considered high-risk?
Stocks

Certificate of Deposit

Answer: Stocks
Step-by-step explanation: People mainly live on wim's so stocks at times can be unpredictable.
suppose that the value of a stock varies each day from $8.82 to $16.17 with a uniform distribution. find the third quartile, i.e., 75% of all days the stock is below what value?
The third quartile is $10.6575, which means that 75% of all days the stock is below this value.
The range of the stock price is from $8.82 to $16.17, and the distribution is uniform, which means that the probability of the stock price being any value between the minimum and maximum is the same.
To find the third quartile, we need to find the value x such that 75% of the observations are less than or equal to x, and 25% of the observations are greater than or equal to x.
Since the distribution is uniform, we can find x by finding the value that separates the bottom 25% of the distribution from the top 75% of the distribution.
The bottom 25% of the distribution spans from $8.82 to some value x. Since the distribution is uniform, we can find x by setting the probability of the stock price being less than or equal to x to 0.25, which gives:
(x - 8.82) / (16.17 - 8.82) = 0.25
Solving for x, we get:
x - 8.82 = 0.25 * (16.17 - 8.82)
x - 8.82 = 1.8375
x = 10.6575

The probability of the spinner landing on the letter C is 1/4
To understand the probability of the spinner landing on the letter C, we need to start by looking at the total number of possible outcomes. In this case, there are four possible outcomes, corresponding to the four letters A, B, C, and D.
Since each of the four quadrants on the spinner is equal in size, each of the four letters has an equal chance of being landed on. Therefore, the probability of the spinner landing on the letter C is the number of ways that the spinner can land on C, divided by the total number of possible outcomes.

the estimated simple linear regression equation minimizes the sum of the squared deviations between each value of y and the line. True or false
The given statement "The estimated simple linear regression equation minimizes the sum of the squared deviations between each value of y and the line" is true because it provides the best fit line.
The simple linear regression equation estimates the relationship between two variables - a dependent variable (y) and an independent variable (x) - by fitting a straight line through the data points.
The line is chosen so that the sum of the squared deviations (also known as the sum of squared errors or SSE) between the observed values of y and the predicted values of y on the line is minimized.
In other words, the simple linear regression equation finds the line that is closest to all the data points in terms of the vertical distance between the points and the line.
This line is chosen to minimize the sum of squared deviations because it provides the best estimate of the relationship between x and y, and it allows for the prediction of y values for a given x value.
Thus, minimizing the sum of squared deviations is a crucial aspect of the simple linear regression equation because it ensures that the line of best fit provides the most accurate estimate of the relationship between the variables.

Hence, the rate of change of temperature after 4 minutes can be used to calculate the additional time it will take for the liquid's temperature to decrease from 70°F to 35°F:R = (T₂ - T) / t₂ = (35°F - 25°F) / t₂t₂ = (10°F / R) = (10°F / 111.25°F/minute) = 0.089728 minutes ≈ 5.38 seconds.
Adding this time to the initial 4 minutes, we have the additional time it will take for the temperature of the liquid to decrease to 35°F after 4 minutes: t = t₁ + t₂ = 4 minutes + 0.089728 minutes ≈ 4.089728 minutes or 4 minutes 5.38 seconds.
The additional time it will take for the temperature of the liquid to decrease to 35°F after 4 minutes is 21.54 minutes (rounded to two decimal places).
